granite countertops

Granite is the ultimate in durability and beauty, but it’s still vulnerable to erosion. When a rock develops tiny cracks that can be filled by water or air particles, then there will slowly start being cloudy spots on your granite countertop which ruin its surface appearance completely.

When it comes to the lifespan of your granite surface, water might be number one on that list. With this in mind, I’ll take a look at the best granite sealers which can waterproof and increase your granite’s durability for years.

1. Stonetech Bulletproof Sealer – Best Granite Sealer

This is a penetrating sealer for granite, and the formulation is obviously designed to maximize that feature. The advertising repeatedly refers to something called “microbond protection”. This means that Stonetech Bulletproof Sealer will supposedly bond with the stone surface in a way that is stronger and longer-lasting than other sealers of this type.

I can say that this sealer is one of the most long-lasting sealers on the market. When we look at the reviews for this sealer they seem to be quite positive. There are a few complaints, but well over half of the reviews that we see are positive ones. Let’s start by looking at the better qualities.

Versatility Is High

I’ve have used Stonetech many times. I can definitely say that it’s very easy to apply, so do most reviews.

Overlap doesn’t seem to be a problem, as everyone reports a sealer that makes a good smooth layer regardless of application method. Some users say that they used a “flooding” approach while others did the job in small spots. Either way, it comes out very even.

This granite sealer also seems to do a good job of creating a glossy sheen without darkening the stone.

No one wants to dull the natural color of granite, as this is one of its main strengths. In terms of longevity, this one lasts for five years on interior surfaces and 3 years on external surfaces.

The complaints about this sealer are pretty inconsistent, which speaks well for the quality. The most common complaint is the relatively short shelf life. Stonetech Bulletproof is only good for two years unopened and one year after being opened. This means that you should only buy what you need for a particular job. Some others said that Stonetech left a haze on the top of the stone surface. But in my opinion, all those problems are caused by the improper application.

  • Easy to use granite sealer
  • Quick to dry
  • Lasts 3-5 years
  • Water-based, no nasty chemical smell
  • One of the most expensive
  • Can leave a haze on the surface if done wrong way

2. Trinova Granite Sealer And Protectant – Top Granite Sealer and Polish

As the name of this sealer implies, Trinova Granite Sealer And Protectant is a combination sealer. Not only does it seep into the pores of the stone surface and seal them thoroughly, but it also creates a protective layer over the surface of the stone. Although this might have the potential to dull the coloration of a beautiful and multicolored granite surface, it definitely provides superior protection.

Spray Bottle

When we look at the reviews, one thing that we immediately see is a pattern of people having problems when using a spray bottle. Although the manufacturer’s instruction advises this method of application, most people seem to get better results using a damp cloth or soft brush. They even included a special extra-long spray nozzle, but it doesn’t seem to help matters very much.

Still, everyone seems to agree that Trinova provides a strong, shiny, and non-stick coating. It’s great 2-in-1 polish and sealer.

The advertising says that this property comes from an advanced mix of polymers. Another real plus is the fact that this sealer is designed to work on grout. Although any granite sealer can theoretically do a good job of sealing up some grout, a lot of them seem to have trouble with this task in practice.

Inexpensive And Easy To Use Sealer

Trinova does get a few points for its low cost. It is one of the cheapest sealers on this list.

Trinova does get a few points for its low cost. It is one of the cheapest granite sealers on this list. This means that even if the coverage isn’t as good as advertised (which is always possible) it won’t really be that big a deal because another bottle won’t cost you a whole lot of money. This granite sealer also loses a point or two for the fact that it usually requires some buffing in order to achieve a truly clear and shiny surface.

  • Quick-drying time
  • The sealer is designed to work on grout
  • Seals and creates a protective layer as well
  • Suitable for food preparation surface
  • Spray bottle doesn’t seem to work as well as a wet cloth
  • Might require a little buffing for a clear finish

3. Granite Gold Sealer Spray – Easy to Use Sealer

This is another spray-on sealer, and it offers many of the same advantages and disadvantages that I have seen before in sealers of this type. It’s a water-based formula that is intended for maximum ease of use.

Not Harsh Sealer

This is a relatively non-toxic granite sealer. I ain’t sure just how “non-toxic” the sealer really is, because the package still has a warning. It says to keep this sealer away from small children, so it must not be completely safe.

Still, this is not an acid-based formula, which is good because you don’t have to worry about yellowing or other discoloration. This granite sealer creates a surface that is safe for food preparation, and it’s also biodegradable for those who care about that sort of thing.

Not Permanent

This sealer will need to be re-applied about once a year. The manufacturer recommends that you re-do the finish every 12-18 months, so once a year is a very conservative estimate. While this is a fairly long duration, it still creates more work and expense over the long haul.

Gloss And Durability

One of the good things about this granite sealer is the shine that it offers. This complements the moisture-resisting properties of the sealer with the elegant look of a Roman palace. This finish is also quite durable so that you won’t scratch it too easily. I also like the fact that this sealer can be used on virtually any type of stone surface.

The only bad part is that you will need to use multiple coats if you want these benefits. The manufacturer recommends 2-3 coats for the best results, which reduces the convenience factor somewhat. Also, you cannot polish the surface for 24 hours after application.

  • Provides a hard and durable finish
  • Improves shine of a surface
  • Can be used on nearly any type of stone
  • Safe for food surface use sealer
  • Ready for re-coating in 20 minutes
  • Usually requires multiple coats
  • Must be re-applied about once a year
  • Cannot be polished for 24 hours after application

4. Tuff Duck Granite, Marble and Grout Sealer – Another One Great Sealer

This one seems attractive to the eye, maybe because of the angry and militant cartoon duck on the label. When we look closer, we see that this sealer claims to include twice the active ingredients used by other brands. If true, this might not actually translate to double the effectiveness, but it’s definitely a plus.

Simple And Non-Toxic Sealer

Tuff Duck is a water-based formula, which is good because it won’t burn your nose so badly when you are working. It is a penetrative granite sealer that is designed to preserve the natural appearance of the stone surface in every way. This means that it isn’t adding beauty to the stone, but it certainly isn’t taking anything away from it either.

Excellent For Waterproofing

Tuff Duck lasts 3-5 years, much like other sealers on this list. Coverage is very good with this sealer, as you can do about 200 square feet per quart.

Based on the advertising, this granite sealer is especially intended for use on grout surfaces. Even most of the critical reviews (of which there aren’t very many) admit that Tuff Duck sealer will do a good job of repelling water.

However, there was more than one complaint that said that the layer was too thin. It could be that the sealer was diluted a little bit too much in order to cover more area. But trust me, I have used this sealer so many times and I haven’t seen any problems yet. Also, this granite sealer is only good for natural and porous stones. Any other type of stone will simply repel the sealer.

  • Very good water protection
  • Particularly good on the grout surface
  • Higher level of active ingredient
  • Simple sealer, protects from moisture with no frills
  • A little too thin if applied wrong

5. Miracle Sealants Impregnator Penetrating Sealer – The Eternal Sealer

With a name like “impregnator,” you can get a pretty good idea of how this granite sealer works. It is made to penetrate deeply into the surface of the stone and provide an exceptionally long-lasting effect.

Sealer that Lasts An Insanely Long Time

The main thing that stands out about Miracle Impregnator is its longevity. It is meant to last for up to 20 years. Apparently, the sealer is designed for indoor or outdoor use. This longevity is backed by a money-back guarantee that is subject to certain conditions.

Long Warranty With Many Provisions

There are quite a few conditions to this warranty, but most of them are just ways for the company to say “if you destroy your granite surface through your own stupidity, we won’t pay for that mistake.”

The only condition that might be a problem is that the guarantee does not cover grout use. Commercial use is also not covered under the guarantee, which may be a big problem for contractors.

Several reviewers complain of a strong chemical smell when using this granite sealer, and it seems to last quite a few hours before subsiding. This is a good reason to always put a fan in the door or window when working with this stuff. Good ventilation combined with a mask can do a lot to make the job more pleasant.

It’s Easy To Make A Mistake With This One

The only consistent complaint with this granite sealer is that it isn’t easy to use. Apparently, it has to be applied very carefully to avoid smudging or discoloration. There aren’t many complaints, but almost all of them center around this problem.

  • Long-lasting sealer
  • Good for indoor and outdoor surface
  • Money-back guarantee covering the full 20 years
  • Provides an invisible barrier
  • Smells very bad but not for long
  • Difficult to apply without ruining the surface

6. Supreme Surface Granite Sealer and Polish – Top Granite Cleaner and Sealer

This is of the cheapest sealer on my list, but it also comes in the smallest package. Supreme Surface only comes in an 8.5-ounce bottle, but they attempt to pack every possible function into that little bottle. Supreme Surface is advertised as being a cleaner, a polisher, and a sealer all in one.

Both Cleaner and Sealer

There were some doubts as to whether this sealer achieves all three of its aims,  but I can say that it definitely does a great job cleaning the surface. Despite the fact that it’s a good cleaner you need to do preparatory cleaning if your granite surface is in very bad condition.

This sealer is meant to be sprayed onto a stone surface and rubbed with a cloth. This quick and easy method makes re-application a breeze. Another thing that contributes to this easy re-application factor is the lack of a strong chemical smell.

The smell is not deceiving in this case because this granite sealer contains no alcohol, no ammonia, and no non-biodegradable materials whatsoever.

Apply it Properly

There were a number of complaints from people who said that Supreme Surface simply didn’t work. However, they probably failed to realize that this granite sealer is meant to be sprayed on stone surfaces in very thin coats. As such, it takes a few more coats to do the same job, and those who aren’t prepared for this fact might be convinced that the sealer is ineffective.

  • No bad smell
  • Environmentally friendly granite sealer
  • Three functions in one
  • Very cheap sealer
  • Re-application is extremely easy
  • Great surface cleaner
  • No info on longevity
  • Requires more coats to do the same work

7. Miracle Sealants 511 Porous Plus Sealer – Great Sealer for Floors

This is a special-purpose granite sealer that is meant to preserve the natural feel and texture of the surface of the stone. Although this might not be ideal for stone coat countertops, it’s a great thing for granite or other stone floorings. You don’t want your floors to be too smooth, as that will create a slip hazard. At the same time, you want them protected from moisture. This sealer is meant to be the solution to this quandary.

Permanent But Invisible Sealer

This isn’t one of those sealers that will have to be re-applied. One job is supposed to last up to 20 years before losing its water resistance. Not only that, but the sealer contains ingredients that make it resistant to UV light degradation. It works by simply allowing UV light to pass through. Light can get through, but moisture cannot.

What surprises many people is the fact that this sealer does not alter the appearance of the stone. Instead of filling in the pores that give the granite surface its texture, this substance penetrates without filling. Thus, you get the best of both worlds.

Slightly Inferior Stain Resistance

Although this granite sealer does fulfill its stated purpose, the porous surface that it creates will be more vulnerable to staining. This is the case because offending substances (like coffee, paint, etc.) have a chance to penetrate the stone, making them much harder to remove from the surface.

Not Eco-Friendly Sealer

This one is definitely not good for the environment. When using this granite sealer on an indoor surface, you will need to make sure that you wear some kind of mask so that the fumes do not make you ill. It’s also a good idea to dispose of all waste carefully so that you minimize any contamination. Also, be sure to keep flame and heat away from this stuff, as it is highly flammable.

  • Lasts up to 20 years
  • Great coverage (1000 feet per quart)
  • UV transparent sealer
  • Safe for food prep surface
  • Meant to preserve the natural texture
  • Pretty expensive granite sealer
  • Smells terrible
  • May not do a good job of resisting oil and grease

8. Black Diamond Stoneworks Granite Sealer – Finicky But Effective Sealer

This is a water-based penetrating granite sealer that is meant to be easy and simple. The spray bottle makes it easy to apply, although the bottle is not included when you buy a large bottle. Still, this professional granite sealer does a great job of sealing a granite countertop surface to prevent staining. Being a water-based granite sealer, it leaves a hard finish that resists scratching and scuffing with effectiveness.

A Kinder, Gentler Stone Sealer

This is also one of the least harsh granite sealers that I have used. By that, I mean that it doesn’t have a very strong odor, and it isn’t made with a brew of toxic chemicals. In fact, most users say that it has a smell that is reminiscent of lemons. For those with pets or small children in the house, this is definitely a plus. Not only that, but this sealer is also a fine choice for kitchen surfaces because of its non-toxic formula.

Some sealers can discolor the surface of the stone if they are left too long. Thankfully, this is not one of them. However, they may have sacrificed some of the effectiveness of the sealer in exchange for this gentler formula. Some customers have complained that this sealer simply did not seal the surface properly, leading to staining problems.

Follow The Instructions Carefully

The consensus on this sealer seems to be that it is very good, but only if you follow the instructions completely. Even a small deviation from the recommended process can lead to bad results. For instance, failure to quickly wipe away the excess fluid can result in a cloudy surface that always looks dirty. However, there is a much bigger problem with this sealer.

The biggest issue with this granite sealer is the fact that it doesn’t last very long on the surface. It has to be re-applied every four to six months, and six months is a very optimistic figure. Considering the relatively high price of this sealer, that is a serious downside.

  • Very easy to apply sealer
  • Penetrates deeply for better resistance
  • Low-odor granite sealer
  • Safe for food surface
  • Not toxic or corrosive
  • Has to be re-applied every 4-6 months
  • Creates a slightly “cloudy” appearance
  • Some customers have complained of inferior stain resistance

9. Aqua Mix Sealer – Decent Sealer For The Big Jobs

When you’ve got a large surface to seal, this is one granite sealer that is tailor-made for your needs. It is a water-based penetrating sealer that is designed to preserve the natural look and feel of the stone. This is a difficult thing to achieve, but most seem to agree that this granite sealer does the job.

Keeps The Natural Look

Some people prefer the look of polished stone, and for these people, this sealer would not be ideal. However, there is something to be said for the look of natural stone. Some people like that rough-hewn look, and some people like the rough feel of stone underneath their hands or feet.

Durable and Long-lasting Sealer

Like any water-based sealer, this granite sealer will dry very hard and will resist damage with ease. In this case, the resistance should be even greater since the sealer is embedded deeply within the stone. It may actually strengthen the stone surface and keep it from breaking as well. According to the manufacturer, this sealer will last for up to 15 years once applied.

Possible Issues

This sealer will usually require multiple coats. In fact, some users claim that they needed more than three coats to do the job, so that is a problem in terms of value. If you overdo it, you can end up with a thick layer of chalky material, which will likely be covered in whitish blotches.

There are also some concerns about the antimicrobial component of this sealer. The granite sealer is impregnated with Microban (technically called Triclosan). Although there is no doubt that this substance works, there are some reasonable questions regarding its use. Some studies have shown a link between Triclosan and certain types of cancer.

  • Mold and mildew resistant sealer
  • Works on many different types of stone
  • Safe for food surfaces
  • Doesn’t change the appearance of the stone
  • Lasts up to 15 years
  • Not available in smaller sizes
  • Requires multiple coats
  • Can create a chalky look and feel on a surface
  • Some have concerns about the use of Triclosan

10. Tenax Marble and Granite Sealer – Great Value Sealer

This granite sealer provides great value with good results. There are several ways in which this sealer is helpful for those who want to save money on a medium to a large project. For a start, I might mention that this sealer is one of the cheapest sealers on my list.

Why Tenax Is A Great Value

Coverage is excellent for this granite sealer, so you should be able to get a lot of use from one quart as long as you are careful. Obviously, a sloppy application technique will cause you to waste some of the sealers, but that can easily be avoided.

Another great thing is the fact that this sealer only needs to be applied once. Unlike many stone sealers, you can slap it on there and forget about it. With some other sealers, you would need to mark your calendar to remind yourself to re-apply the sealer. Chances are, you don’t need another obligation in your life, especially one that is completely optional.

Easy To Use Sealer

Most users say that the easiest way to apply this granite sealer is to dab it on a piece of scrap cloth. This could be a strip from an old bedsheet or a stained T-shirt, as any cloth will do. In any case, the process is made much easier by the fact that this sealer dries so quickly. Within ten minutes, you are ready to start buffing and polishing your surface.

The best thing about this fast-drying formula is that you can do large surfaces (like floors) in minimal time. However, although this granite sealer does dry quickly, you will not see the water-repelling effects until 24 hours later.

Quite a Toxic Sealer

Most of the downsides of this sealer come from its harsh and toxic nature. There is a very strong smell, requiring you to use some kind of breathing protection when using this sealer indoors. In addition, there are some questions about whether or not this sealer is safe for use on kitchen countertops.

This stuff is so harsh that it is classified as a hazardous material, which means that you could run into trouble when ordering this granite sealer by mail. Obviously, it depends on where you live, but shipping costs are likely to be higher no matter where you are.

  • Excellent coverage
  • Very inexpensive compared to most others
  • Dries quickly (within ten minutes)
  • Provides exceptional moisture resistance
  • Only needs to be applied on a surface once
  • Very toxic sealer
  • Several customers report discoloration after use
  • Shipping limitations
  • No real water resistance for 24 hours

11. Black Diamond Stoneworks Granite Plus 2 in 1 Cleaner & Sealer – The Sealer For Everyday Use

Are you searching for a streak-free clean granite cleaner? This 2-in-1 granite cleaner & sealer could protect your countertop from spills.  Black Diamond could seal your granite countertop and other natural stones similar to granite. This is not a stand-alone granite sealer though.

Built-In Sealer

This granite cleaner and sealer could save your countertop surface from spills coming from household stuff such as coffee, wine, peanut butter, oil, and food stains. Black Diamond should be able to keep your countertop skid-proof to protect your kids from accidental slip-ups.

Easy to Apply Sealer

This sealer is easy to use. All you need to do is to spray it on the granite countertop and wipe it down after use. You need to purchase the sprayer bottle separately because this sealer does not come with the sprayer.

Cleans All Natural Stone

You can use this cleaner and sealer for other natural stones besides granite such as marble, travertine, limestone, quartzite and travertine. This granite sealer could also work on man-made quartz surfaces too. However, you can only use Granite Plus for maintenance cleaning purposes only. If you need a stronger granite sealer you might need to look for another sealer to do the job.

Everyday Cleaning Needs

Every time that you use Granite Plus to clean your granite it fortifies the performance of your granite sealer. Normally, you can use this sealer to clean not just your kitchen countertop but, on the shower and floor surface too. Make sure that you have wiped the surface clean first before you apply this granite sealer. Don’t forget to allow this sealer to dry first to avoid streaks. It is advisable to use microfiber cleaning cloths to get maximum results.

  • Seals and cleans granite surface
  • Fewer times spend on countertop maintenance
  • Good maintenance cleaner for all types of natural stone
  • Keeps kitchen countertop safe for kids
  • Gives a granite surface a nice bright shine
  • Pleasantly scented
  • Use every two months for surface maintenance
  • Not for embedded stains on marble
  • Not a sealer to seal tile grout
  • Not strong enough to remove soap scum

12. Tenax Ager Marble and Granite Sealer – Color Enhancing Wet Look Stone Sealer

If you are trying to find ways to preserve the color of your granite countertops Tenax Ager is just for you. This sealer could intensify the beauty of your granite by giving the countertop a permanent “wet” look appeal. This granite sealer does not change color when exposed to the sun thanks to its “UV” stable properties.

Water Repellant

You can only appreciate the water repellant effect after 24 hours of applying this stone color-enhancing sealer. This sealer should be able to protect kitchen countertop surfaces against water, oil, and stains. For best and quicker results, use in a well-ventilated space. Otherwise, you might need the help of an industrial fan.

Long-Lasting Sealer

Tenax Ager is said to be premium-grade high-quality sealer that makes your granite last for a long time. There are other cheaper stone darkeners out in the market but, they quickly fade. Don’t spend your money on imitations if you want to save on cash, choose to buy this stone color enhancer instead. On average, each two-coat application can last for a year or a bit more.

Retains Color

Some other color-enhancing sealer will fade quickly failing to protect the stone.  You should get the darker granite effect by using at least 2 coats of this color-enhancing sealer.  You can even use Tenax Ager to enhance old terrazzo floors.

Don’t forget to test a small area first to see the results before you proceed in applying this sealer over the entire floor. This sealer can improve color retention if you use it in rough, sanded or flame textured granite surfaces.

Solves Color Mismatch

To solve the edge color mismatch this granite sealer should be applied after polishing the edges. For best results, you must ensure that you use this before any other standard “impregnating” sealer.  Otherwise, Tenax Ager won’t absorb well at all. Use as many coats as needed to get the best color match for your countertop surface.

Correct Way to Apply

If you accidentally mess up the application you can simply correct this by reapplying the sealer. Use a damp cloth and rub a small area. Subsequent rubbing will make the messy coating even out. Switch to using a clean dry cloth to rub all traces of the damp sealer.

This will leave a beautifully sealed surface. You can actually use a brush, sponge with gloves instead of using cloth when applying the sealer. When you apply it properly this will cause a blending effect on potholes.

  • Hides micro fissure and small scratches
  • Deep rich color
  • Color enhancing effect
  • Versatile edge color mismatch
  • Remains stable even in sun exposure
  • Indoor and outdoor environment application
  • Magnifies “wet” effect on a surface
  • Available in Packs of 1 to Packs of 4
  • Subsequent applications will not produce better results
  • Not a filler
  • Blending effect; not for potholes
  • Does not have the same results in manufactured synthetic stone

13. Stone Care International Granite Sealer – Sealer with Protection for Natural Stone

To ensure that your granite looks great and remains that way for a long time you need a sealer that can expertly protect your granite stone.  This sealer is a penetrating sealer that forms adjustable molecular links to effectively protect the granite and stone surface.

What Makes This Sealer Unique

Unlike coating sealers, this penetrating granite sealer can reach into the pores of the stone for thorough protection. To get the best results you must apply this sealer on a dry surface. Stone care could protect stone surfaces from water and stains. This granite sealer should be able to allow the stone to breathe; releasing moisture vapors.

Shine Retention

Surprisingly, this granite sealer should be able to keep the countertop surface shiny even after you clean the granite counter. Most buyers are pleased with the results. I noticed that Stone Care protects the granite from water spots but, it was not yet observed if it can still protect the granite a few months after.

Sealer That Works on Travertine

This sealer works on rough travertine or limestone surface. Don’t forget to follow the directions found on the bottle. This granite sealer can also work on honed travertine. However, don’t expect to see a change in the overall look of the stone. Stone Care will just protect the honed travertine against staining.

Not For All Stone Types

This sealer could be a good granite sealer for some stone surface types but, it is not for flooring because there is a need to wait for the pre-treatment time to do its job.

Tips on Sealing

Before you begin to seal try to remove all the items on the surface. Be sure that the surface is clean and completely dry before you start sealing. To get the best results you need to work at above room temperature using a microfiber cloth.

Allow the first coating to dry up first at least 3 to 5 minutes before you do the second application. Certain colors of granite or stone may require you to repeat for an additional application. Once the application is complete wait it to dry for 24 hours. This will completely cure and bond the seal onto the stone.

  • Safe to use on food contact surfaces
  • Penetrating sealer
  • Easy to apply; spray, wipe and seal
  • Use on all solid stone surfaces
  • Streak-free formula
  • Superior coverage with 1 application
  • Ammonia and phosphate-free
  • Track record more than 50 years in the business
  • The surface takes 24 hours to dry
  • Needs a well-ventilated area to allow faint ammonia fumes to escape
  • An additional application for porous stones
  • Use every six months for best results
  • Issues about leaky bottle when delivered

14. Stain-Proof Premium Impregnating Sealer for Stone – Another Decent Sealer

This is a heavy-duty sealer that is designed to be stronger than average. I can see that the goal was achieved because this product is definitely a lot stronger than the average sealant. It penetrates deeply into the stone, creating a hard and durable finish that is suitable for counters, floors, or any other granite surface.

Lets Moisture Evaporate

One good thing about this sealer is the fact that it lets the stone “breathe.” This means that there are microscopic gaps in the finish. Those gaps aren’t big enough for water or oil to penetrate, but they are big enough for air or vapor to escape. That’s a good thing because it keeps the sealer from locking in moisture, as sometimes happens with other sealers. This one is also suitable for indoor or outdoor use.

Not for Small Jobs

Where most sealers need to be re-applied every year or two, this one claims to be a permanent job. If true, that does help to justify the high price of this sealer, but it’s still pretty expensive. I would recommend this one for serious jobs only because of its high cost. You usually need 2-3 coats of this stuff to seal a surface properly, but each coat only takes about 10 minutes to dry. Thus, you can be done pretty quickly.

As high-end sealers go, this is considered to be one of the best. Reviews for this product have been about 80% positive, which is always a good sign. It gives one of the most stunning mirror finishes that I have ever seen, so it’s definitely a great choice for the people who like their shine.

  • Each coat dries in only ten minutes
  • Allows the stone to breathe
  • Provides very long-lasting protection
  • Provides a beautiful mirror finish
  • Suitable for indoor and outdoor use
  • Pretty expensive
  • Usually requires three coats

15. Stone Pro Granite Sealer – The Sealer Against Oil and Water

Pro Sealer works as a multipurpose impregnating granite sealer.  Stone Pro Sealer performs better by penetrating polished calcite that includes granite, marble, travertine, limestone, terrazzo, and onyx surfaces. This sealer should work on both honed and very porous limestone. One coat should be sufficient for use on the travertine surface.

Cheap Sealer

I can say that Pro Sealer is sold at a less expensive price than most solvent-based granite sealers. You get solvent protection sold at a water-based sealer price.

Water and Oil Repellant

Pro Sealer is said to be an excellent oil and water repellant sealer. It is not too thick nor too thin. The sealer is actually watery which will make it easier to apply. Since this sealer is water-based there is no need to dilute it in water. You just need to follow the directions on the container.

No Bad Odor Fumes Sealer

For those who are concerned about odor fumes, this granite sealer may smell a little bit since it’s diluted, the slightly stinky smell will quickly go away. This granite sealer can be applied even in an enclosed room since this sealer does not emit strong odors.

Easy Application

No scrubbing is required because it should be easy to apply using a sponge mop. There is no need to go on hands and knees nor a need for long handle application. This sealer does not leave a residue or streak on the surface. It will take from 24 to 72 hours in order for this granite sealer to fully cure. This will depend on the kind of natural stone where it was used for.

Not for Sealing Countertop Paint

You cannot use this to seal the paint since the sealer soaks into the stone.

  • Long-lasting surface protection
  • Cheaper solvent-based protection
  • Safe on food preparation areas
  • Non-flammable
  • No odor fumes
  • Extremely durable
  • Volatile Organic Compliant
  • UV stable
  • Suitable for indoors and outdoors application
  • Well packaged
  • The level of stain is not as good for marble surfaces
  • Not allowed to use heavy soap and sealers because of too much surfactant
  • Surface must be reapplied after six months 

16. More Premium Stone Sealer – The Sealer for Natural Stone and Tile Surfaces

More Premium Stone Sealer protects the countertop surface by enhancing the natural stone.  This granite sealer works best on almost all different kinds of natural stone such as granite, marble, stone, clay, slate, tile, and a lot more.

Solid Barrier

The “polymers” More Premium Stone Sealer formula contains are said to build an invisible barrier not just on stains. This granite sealer effectively protects grout to preserve and make it look almost new. I find the seal and protect features of this sealer practical as a stain protector both for indoor and outdoor surfaces.

Works on Most Surfaces

Apply generously on the surface. This sealer should leave behind smoothly covered surfaces without bumps. This granite sealer improves the natural stone’s color and texture.

Safe and Effective Sealer

More Premium Stone Sealer should be safe enough to use even in all rooms of the house. This sealer should be efficient and safe enough for everyday use. Aside from using a spray use a paintbrush and let it dry for at least 15 minutes as directed.

Makes Cleaning Easier

This granite sealer is simple and safe to use. It should provide an effective way of keeping the countertop spill-free without leaving behind stains on the stone.  More Premium is effective in dissolving dirt and oil which makes the surface easy to clean.

More Sealer has faint peppermint and thyme scent leaving the room smelling fresh and clean. It appears that there are no issues about untoward odors when applying this sealer.

17. HMK S234 Stone Impregnating Sealer – Sealer Without Shine

This is another solvent-based granite sealer. Solvents penetrate deeper than water or oils, allowing this sealer to penetrate much more deeply. That leads to a thicker finish with more of the stone protected from damage.

Preserves Natural Look of The Stone

This one does not add anything to the natural look of the stone. In fact, it doesn’t even add that much of a shine. If you like the look of natural, unpolished stone, this product might be just what you want. It’s also vapor-permeable, which is very helpful. If some moisture should happen to get trapped in the stone, this sealer will allow it to evaporate away.

This one is safe for food prep surfaces while still being tough enough for floors. That’s a great balance between two extremes, so the manufacturer deserves a little bit of credit for that. I also like the fact that you only need two coats of this sealer. Some of the more absorbent types of granite may take three coats, but most will be fine with two. That might have something to do with the thick and goopy consistency of this product.

Some Problems

Of course, I do see a few problems as well. This one is still pretty expensive, and some people may not like the fact that it doesn’t make the stone slick and shiny. In order for this sealer to adhere, the surface must be exceptionally clean and dry. The label says that it’s best if the surface hasn’t contacted liquids in at least 24 hours. This one also takes a little longer to dry; You’re looking at 2-4 hours of dry time and about 48 hours of curing time. That’s a little bit inconvenient, but the results are well worth the wait.

  • Solvent-based for extra strength
  • Preserves the natural look of the stone
  • Vapor permeable
  • Safe for food prep surfaces
  • Usually requires just two coats
  • Takes a while to dry (4 hours to dry, 48 to cure)
  • Requires serious cleaning and drying of the surface

18. FILA Solvent Based Sealer – Safe Sealant

The FILA Solvent Based Sealer is designed to seal surfaces of granite and protect the surfaces from damage or stains. The solvent-based sealer does not only protect granite countertop surface alone, it also acts and protects the natural stone, marbles, and porcelain. It also acts as a water repellent as water destroys surfaces. The sealer is regarded as a deep sealant, it penetrates deep to protect surfaces from stains, moisture, and other types of contaminants.

Safe for use in food areas

It is always difficult selecting a sealer to use interiorly, especially in sensitive areas where food is being prepared or handled like the kitchen. Foods can be predisposed to toxic chemicals that are contained in some sealers. For FILA solvent-based sealer, there is no risk to food or health, it complies with the recommended level of Volatile Organic Compound (VOC).

Food preparation countertops surface made of granite, marbles, porcelain, natural stone, etc can easily be sealed with the FILA solvent. It contains no toxic fume or odor as well. The safety of the MP90 for use in food-sensitive areas is certified by regulatory bodies.

Seals and protects surfaces

The major expectation of sealers is to protect the surface they are applied to, surfaces like granite or tiles require sealers to keep their surfaces intact and get protection from external materials. FILA sealer is produced with the use of Solvent technology, the technology offers extended protection onto surfaces. FILA sealer dissolves stains and grim on surfaces and goes further to penetrate deeply into surfaces to give long-term protection to surfaces.

The process of application of FILA sealer to surfaces is quite simple, as a beginner, you can easily apply this sealer yourself without the assistance of a professional. FILA seals and protects the all-natural stone, porcelain tile, quartz, and granite surface. Surfaces should be cleaned and kept dry before the application of the MP90 solvent sealer, you can use a paintbrush to apply a generous coating of the sealer. It is best to give about the surface about 10 minutes before wiping to allow it to penetrate deeply.

Leaves surfaces in a natural state

Granite surfaces and other types of natural surfaces have a very attractive visual appeal and smooth surface, however, if the surfaces are left unprotected, they get stained and marred. The FILA solvent sealer solves this problem by sealing and protecting the surfaces of these stones, it doesn’t stop there, the solvent leaves the surfaces in their natural state or color.

The natural stone look and surface are preserved without discoloration or deterioration. FILA Solvent also gives long-lasting protection to such surfaces, it makes maintenance of the stone surfaces easy to carry out.

  • It does not form a film or change the natural look of surfaces over time.
  • The sealer is water repellent and suitable for use on surfaces constantly exposed to water.
  • The sealer does not protect marble and limestone from acid stains.

19. Dupont Stone Sealer – Long-lasting protection

The Dupont Stone sealer is large, it comes in a one-gallon container large enough to cover large surfaces and saves the cost of having to buy more sealers for a project. If you have just newly installed your tiles or granite countertops, or you are planning to carry out a renovation the Dupont stone sealer is one of the best options to go for in terms of size and quantity. The Dupont stone sealer is not only significant for its size alone, it also protects surfaces and gives long-lasting protection.

Long-lasting protection

A desirable trait for sealers is their ability to protect surfaces for a long time, nobody wants to keep changing sealers or reapplying sealers frequently, the process of applying granite sealers can be time-consuming and resource-draining. It is best to have a sealer that does the job once and protects your surface for a long time.

The Dupont stone sealer protects the surface and not just as a one-time thing, it protects surfaces for a long time. The stone sealer protects surfaces for up to 2 years, this long-term duration is beneficial to surfaces that require a great deal of protection and prevents damages from moisture or stains.

Tiles, granite, and other surfaces that are exposed to moisture and steam, the exposure to moisture weakens seals placed on these surfaces and tiles. Moisture and steam can constantly damage these surfaces. The Dupont Stone sealer is great for a lot of surfaces like granite, marble, and travertine, and when these types of stones are used in moisture exposed areas. The stone sealer creates a strong barrier over surfaces and seals them off, this makes Dupont reliable and efficient in protecting surfaces from damage.

Another added advantage of using the Dupont stone sealer is in its form of protection. It forms a dual means of protection; it protects against both water-based and oil-based stains. The ability to able to prevent both water-based and oil-based stains makes it versatile and desirable for use within the house.

Large Coverage area

Dupont has a large coverage when applied to surfaces, due to its large content it can cover up to 450 square feet. If you have large space or you have several surfaces you want to seal, the Dupont sealer is a great option for use in this regard to have a cost-effective means of sealing.

The Dupont sealer comes in a large container, and might not be convenient for application, you can make use of kits to apply effectively to surfaces, you can also make use of small spray bottles for direct application to surfaces. Surfaces can require more than one coating of sealant for effective action.

  • Dupont gives strong protection to surfaces.
  • It works well with bathroom walls and floors exposed to moisture.
  • The container does not support direct application and takes more time to use.
  • The surface might require more than one coating for effectiveness.

What to Consider When Buying the Best Granite Sealer

Consider the following important factors when choosing the best granite sealer.


First, choose nontoxic granite sealers to do the trick. There are organic or water-based granite sealers sold online that are better alternatives. The latest technological breakthrough consists of coatings that protect your polished stone surfaces using a clear environmentally friendly breathable sealer. Look for sealers that are 100% natural and do not contain harsh chemicals. Using non-toxic sealers like this can help you save on as much as 50% of labor costs.

Food safety

Second, you must choose a food-safe granite sealer. Using stone sealers will prevent deep absorption of liquids. This simply means, your food will not come in direct contact with the stone sealer. It will take 1 to 2 days before the sealer is fully cured. The process will make the granite sealer chemically un-reactive meaning this will not contaminate your food.


Some sealers may be cheap but they aren’t that good at sealing your granite. Also, they aren’t often environmentally friendly and safe for you. It’s better to spend a little bit more to get a good granite sealer that will protect your countertops for years.

stone Colors of Granite Sealer

Lightly colored and white granites are unpolished softer stones that need sealing every 1 to 3 years. Dark-colored granites which include polished marble can be sealed less frequently on average; every 3 to 5 years.  How long granite lasts and perform will depend on your particular stone surface and sealer.

Types of Granite Sealer

There are two main types of stone sealers: penetrating and film-forming.

Penetrating Sealer

A penetrating granite sealer has a high level of ability as a liquid repellant. This type of sealer provides invisible protection to allow moisture to escape from a porous surface. Penetrating sealers are usually used outdoors because it provides excellent protection against severe environmental conditions like change in weather patterns.

Film Forming Sealer

Film-forming granite sealers are used for decorative concrete. There are actually three main types of film-forming sealers. All of these are available in water-based and solvent-based versions. Film-forming sealers range from the thinnest to the thickest. This type of granite sealer produces sheen in different intensities to highlight and enhance the color of the surface where it is used.

Check If Your Granite Really Needs Sealing

Not all granite countertops are created equal. You can use the water test to see if your granite needs to be sealed. Using about ¼ cup of water pour this into the counter. Take note of how fast the water is absorbed into the granite. If you notice immediate absorption you need to apply a couple of layers of granite sealer. For the slow absorption rate of 4 to 5 minutes, you need to re-do the sealer every 3 to 5 years.

Lemon Juice Test

Similar to the water test, you need to place a few drops of juice in an unnoticeable spot on the countertop. If dark spots appear quickly, this means the stone is reacting to an acid. If it takes a minute for lemon to be absorbed, a granite sealer is needed to protect the countertops. If lemon doesn’t absorb, there is no need to seal.

When It’s Better to Seal Granite

Granite sealers must be applied to the polished surfaces of the granite when there is a small amount of airborne dust. If there is ongoing construction in your kitchen you need to do sealing after the final cleaning has taken place.

Sealing Granite in A New House

In case you moved into a previously owned house, generally, you are clueless about whether these are sealed or not. There is also a chance, that the previous owner uses a cheap granite sealer. It would be better to play safe by having these granite tops sealed immediately.

What Granite Sealer Doesn’t Do

There are things that granite sealer doesn’t do. Sealers do not form a protective barrier on the stone surface. Sealers only seal the stone below the surface.  Sealing a stone will not protect it from being etched. Granite sealer does not make the granite shinier. If you want to see a shiny granite countertop you can use granite polish to get the job done.

Taking Care of Your Sealed Granite

If you want your granite countertop to look new for decades you can follow the suggestions given in this care guide. Stick to these easy steps on how to perfectly maintain your granite countertops

Daily Cleaning

Clean the countertop daily by using a damp cloth. Use a few drops of dishwashing soap. Rinse the countertop using clean. Dry it up using a clean cloth. There is no need to use chemicals and other kinds of specializing cleansing materials.

Deep Cleaning

Each week, you made need to do a deep cleaning. You need a pH-neutral cleaner specifically made for the purpose of cleaning granite surfaces. Never use home remedies like bleach, vinegar, or any sealers containing ammonia. These solutions will destroy the countertop surface.


You need to reseal your granite every 12-24 months.

What Not to Do With Your Sealed Granite Countertops

Second, avoid using hot pots and pans directly on the countertop surface. However, experts do recommend using a trivet for crockpots that emit heat for long periods of time. There is a chance that heating one area of the top and not the entire area can cause the countertop to crack. If you can use coasters when placing hot drinks do so.

If you will use the countertop surface to cut vegetables and other food items use cutting boards. This will prevent scratches and etchings left behind by the tools that you are going to use to prepare food.

Frequently Asked Questions

How often should you seal granite countertops?

The answer to this question will vary based on which sealer you use and which kind of stone you have. Some types of granite are much more porous than others, and the more porous types will need to be re-sealed more often.

As a general rule, you need to re-seal your granite countertop once every 1-3 years. Again, this will vary by sealer (the more expensive ones tend to last longer). If you use your counter every day, it should not take long to recognize when liquids are no longer beading on the surface.

How long do you have to wait to use counters after sealing granite?

Once again, this will vary somewhat by stone and granite sealant type. However, you should make sure to wait at least two hours after sealing. If you use your granite countertop before then, the sealer might still be wet.

Make sure to consult the label of your sealing sealer for more specific information on drying time. Regardless of anything, however, you will need to give the counter surface twenty-four hours to cure before you attempt to buff or polish.

Is it possible to protect granite countertops without sealing?

Penetrating sealers represent the only good option for the long-term protection of granite and other stone countertops. By creating a water-repellent surface, you keep water and other liquids from penetrating the stone. Unless you use something else as filler, you won’t get the same level of protection.

Does sealer darken granite?

In general, a sealer will darken the stone slightly, but the difference should be very slight. In most cases, the difference is extremely subtle. Unless someone places a sample of unfinished stone next to the counter for comparison, it will make little to no difference.

When you first apply the sealer, you will probably notice a difference in tone, but that’s no reason to worry. The finish will lighten up as it dries and cures, which shouldn’t take longer than 48 hours. The effect will be more noticeable on textured surfaces and less noticeable on smooth ones.

Can sealer make granite look wet?

Yes, some sealers can make granite look wet. That’s because they contain a chemical called a gloss enhancer. A gloss enhancer makes the surface of the stone look shiny by reflecting light. It can also make colors look more intense.

Some sealers also contain a wetting agent. A wetting agent is a substance that helps water spread out evenly on a surface. When it’s combined with a gloss enhancer, the wetting agent helps the sealer to create a wet look on the granite.

It’s important to note that not all sealers contain gloss enhancers or wetting agents.

Can you use oil to seal the granite?

No, you cannot use oil to seal granite. Oil is typically used to treat wood, but not stone surfaces. Oil can actually make the granite look dull and it can also promote the growth of mildew and mold. Use should use granite or stone sealers instead of oil. These products are designed especially for stone sealing.


Any of these sealers will allow any piece of granite to be used indoors without fear of seeing them ruined by the destructive effects of the water, oils, and stains. However, the best all-around granite sealer on my list is probably the Stonetech Bulletproof. It’s important that this sealer doesn’t try to be all things at once. It simply does one job and does it well.

30 thoughts on “20 Best Granite Sealers 2023 – Reviews”

  1. Make sure when you apply the Tenax Ager that it is for sure not going to rain within 24 hours. I applied mine and then it rained within 5 hours and the whole thing was ruined. I had to restart basically from scratch the next day. It took forever but in the end, the product came out great and if I had just looked at the forecast I could’ve avoided this whole ordeal honestly. Just check the forecast!

    • Hi, Macie.

      Yep, if you’re going to apply sealer outdoors you have to make sure it’s going to rain soon. Thanks for the tip.

  2. Thanks for the article, Robert.

    I can definitely vouch for the Stonetech Bulletproof granite sealer. It worked so well for me and I only ever recommend it to anyone that asks. I totally agree that it created a glossy sheen without taking away from the original color fo the granite. I highly recommend.

    • Hello Brandon.

      Thank you. I agree with you and I think most people may use this sealer even if they’ve never done sealing before.

  3. Tuff Duck is by far my favorite from this list. I have tried a few of the others but they just don’t seem to do the job exactly how I like it. Tuff Duck is easy to apply and is very cost-friendly for the amount and quality you are getting. It helps me not break the bank and still get the job done.

    • Glad to see you on my blog, Jen.

      There are many great sealers on the list, but yes, Tuff Duck is a high-quality product. It’s unlikely to be disappointed with this one.

  4. Thanks for review Robert. I originally bought the Trinova granite sealer and protectant because it was in my price range and I figured I would just go for it. I’m glad I did because not only was it super easy to apply (because of the spray bottle) but it saved me a ton of money! I always go for a good two for one when I can because why do something twice when you can just do it once? My granite looks great and feels great so I can’t complain.

    Thank you.

  5. A lot of people said they had problems using the spray bottle but I can honestly say that never happened to me. I just always made sure I had a rag handy to wipe off the spray nozzle to ensure that the product wasn’t getting stuck or backed up inside the little hole. You have to be able to take care of the product case if you want it to work right.

  6. My experiences with BulletProof brand have always been really great. I really like it because it doesn’t have a crazy chemical smell that makes me want to throw up and gag every time I breathe it in. Some of those other brands cannot be good for your lungs or body with how they smell and make me feel afterward.

    • Hi Justin.

      Lack of smell is a great feature of StoneTech. By the way, there are several other sealers on the list that have no or low odor: Supreme Surface, Black Diamond Granite Sealer and Stone Pro Pro Sealer (smells a little bit but odor quickly goes away).

  7. I laughed the first time I read the name “miracle sealants impregnator.” It honestly is what made me buy it in the first place and it turned out to be a great product. I have only had to use it once in the last decade and the sealant still looks great even after a lot of wear. I’m going to have to redo it soon but I’m in no rush because it doesn’t look horrible.

  8. Yeah, I definitely used the supreme cleaner wrong the very first time. I’m not the kind of guy who actually reads the instructions on anything. I just look at the product and assume how you use it and then just go for it. Sometimes this works out horribly, especially in this case. Always read the instructions.

  9. I suggest using the supreme surface cleaner and sealant when you either just need to do a quick cleaning and touch up to a surface. Or, when you are working with a very small area that is needing to be sealed. It isn’t the easiest to use and I found the bottle would quick working after a few sprays.

  10. My only downside to the Tenax sealer was that it had a really horrible and harsh smell. I opened it up and was getting ready to seal but then the smell hit me and I had to close it up. I went to the store and grabbed some of those face masks and they seemed to help quite a lot but they definitely did not block all of the smell.

    • Yes, The Texas has a strong odor. Make sure you have a respirator or something like that before applying this product. Also, make sure the room is well ventilated.

  11. Great post Robert.

    Polished stone is quite possibly my favorite look throughout the house and I was super worried with sealing and polishing it that it would take away that great natural look. I used an extra piece of the granite and tested different brands out for months and I can now say that the aqua mix is the exact one you need to use if you’re trying to keep the look all-natural.

  12. i don’t know if I have ever followed a set of instructions more carefully. I got the black diamond brand of sealer and all of the reviews said that it needed to be done exactly as stated or it wouldn’t work correctly. All I can say is, while it was meticulous, it came out looking awesome and my countertops can attest to that..

  13. Hi there Robert.

    I was helping my grandparents to seal the granite on their backyard patio and I needed something that was going to be a one and done because there was no way I was going to have time to come up once or twice and year and help them with it. Thanks for the list, I’m glad I chose the tenax stone sealer because it is looking like I may never have to go up there again. We can only hope though because I’m not skilled in granite sealing in the slightest.

  14. For all of my granite countertops, I use the black diamond stoneworks granite sealer and it has great shine and durability in my opinion. Now, the granite is definitely in my house so it doesn’t get the wear and tear of the outdoor elements so I can’t vouch for that. However, inside, this stuff works wonders. In my opinion, it should be the #1 option on your list.

  15. Hi Robert. Thank you, I bought granite gold. I used it on my granite countertops in my kitchen a few months ago and it is still holding strong. The smell really wasn’t that bad when I was sealing them so that was great because I know some really have a bad chemical smell. I don’t do great with strong smells so I tried to find one that would be relatively mild for the sake of my gag reflex.

  16. I tried my hand at the Miracle Sealants Impregnator and I just couldn’t get the discoloration to look right. I don’t know if I was just flat out doing it wrong but it’s not like I haven’t ever sealed anything before. I say it a really great product when you use it right but it’s picky about how you use it.

    • Hi Scott.

      It’s very important to read instructions before applying literally any sealer. It will help to avoid unwanted results.

  17. I wonder why Granite Gold isn’t even in top 5. I use the granite gold sealer for most of the granite in and out of my house. It does need to be redone about once a year but that doesn’t really bother me. I’m retired so it’s something for me to do regularly. It does create an amazing shine which is why I choose to stick with it.

  18. What always gets me about the miracle sealant brand is that they are not eco-friendly by any means. I try my best to do everything in my power to help live a sustainable lifestyle and support the environment in a positive way. However, this sealant is great at its job but not great for the environment. It’s too bad, they need to work on that.

    • Hi, Victor.

      It’s because of Miracle Sealants’ formula. It’s hard to create eco-friendly sealer which will last for 10+ years. Only ‘harsh’ formula can be persistent.

  19. Hi Robert,
    Appreciated your post and all the work in complying the list of stone sealers. In one of your other blogs about using sealer you recommend using one that has fluorocarbon aliphatic resin in it. Do any of the above contain this ingredient?

    • Hi Barbara,

      StoneTech BulletProof definitely contains fluorocarbon aliphatic resin in it as most of the sealers on the list.
