Best Granite Sealers 2019 – Reviews and Buyer’s Guide

granite countertopsFor all its beauty and toughness, granite is still vulnerable to erosion just like any rock. When the surface begins to erode in any way, the appearance becomes cloudy and the beauty of the surface is ruined.

It might surprise you to find out that water is probably the number one threat to the longevity of your granite surface. With that fact in mind, let’s take a look at the best granite sealers that are designed to waterproof your stone surfaces and increase their lifespan.

1. Stonetech Bulletproof – Top Granite Sealer

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

I can say that this sealer is one of the most long-lasting options on the market. When we look at the reviews for this product 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 product 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 option 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. But in my opinion, all those problems are caused by the improper application.

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

2. Tuff Duck – 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 product claims to include twice the active ingredient 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

Tuff Duck is water-based formula, which is good because it won’t burn your nose so badly when you are working. It is a penetrative sealer which is designed to preserve the natural appearance of stone 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 products on this list. Coverage is very good with this product, as you can do about 200 square feet per quart.

Based on the advertising, this sealer is especially intended for use on grout. Even most of the critical reviews (of which there aren’t very many) admit that this product 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 product was diluted a little bit too much in order to cover more area. But trust me, I have used this product so many times and I haven’t seen any problems yet. Also, this product is only good for natural and porous stone. Any other type of stone will simply repel the product.

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

3. Miracle Sealants Impregnator – The Eternal Sealant

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

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 product 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 product, 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 product 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.

Miracle Sealants Impregnator Technical Data Sheet PDF

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

4. Trinova Granite Sealer And Protectant – Best Granite Polish and Sealer

As the name of this product implies, Trinova Granite Sealer And Protectant is a combination product. Not only does it seep into the pores of the stone 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 product 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

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 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 product 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.

Pros
  • Quick drying time
  • Designed to work on grout
  • Seals and creates a protective layer as well
  • Suitable for food preparation surfaces
Cons
  • Spray bottle doesn’t seem to work as well as a wet cloth
  • Might require a little buffing for a clear finish

5. Supreme Surface – Top Granite Cleaner and Sealer

This is of the cheapest product 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 product 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 product is meant to be sprayed onto a stone surface and rubbed in 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 product 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 product is meant to be sprayed 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 product is ineffective.

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

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

This is a special-purpose sealer that is meant to preserve the natural feel and texture of stone. Although this might not be ideal for 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 product is meant to be the solution to this quandary.

Permanent But Invisible

This isn’t one of those products 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 product 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 its texture, this substance penetrates without filling. Thus, you get the best of both worlds.

Slightly Inferior Stain Resistance

Although this product 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.

Not Eco-Friendly

This one is definitely not good for the environment. When using this product indoors, 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.

Miracle Sealants 511 Data Sheet PDF

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

7. Granite Gold Sealer Spray – Ease And Convenience

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

Not Harsh

This is a relatively non-toxic product. I ain’t sure just how “non-toxic” the product really is, because the package still has a warning. It says to keep this product 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 product 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 product 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 product is the shine that it offers. This complements the moisture-resisting properties of the product 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 product can be used on virtually any type of stone.

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.

Granite Gold Sealer Safety Data Sheet PDF

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

8. Black Diamond Stoneworks Granite Sealer – Finicky But Effective

This is a water-based penetrating 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 product does a great job of sealing a granite countertop to prevent staining. Being a water-based sealant, 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 product 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 product in exchange for this gentler formula. Some customers have complained that this product simply did not seal the surface properly, leading to staining problems.

Follow The Instructions Carefully

The consensus on this product 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 product.

The biggest issue with this product is the fact that it doesn’t last very long. 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 product, that is a serious downside.

Black Diamond Stoneworks Granite Sealer Safety Data Sheet PDF

Pros
  • Very easy to apply
  • Penetrates deeply for better resistance
  • Low-odor
  • Safe for food surfaces
  • Not toxic or corrosive
Cons
  • 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’s Choice Gold – For The Big Jobs

When you’ve got a large surface to seal, this is one product 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 product does the job.

Keeps The Natural Look

Some people prefer the look of polished stone, and for these people, this product 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

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

Possible Issues

This product 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 product. The 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.

Aqua Mix Technical Data Sheet PDF

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

10. Tenax Stone Sealer – Great Value

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

Why Tenax Is A Great Value

Coverage is excellent for this product, 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 product, but that can easily be avoided.

Another great thing is the fact that this product only needs to be applied once. Unlike many stone sealers, you can slap it on there and forget about it. With some other products, 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

Most users say that the easiest way to apply this product 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 product dries so quickly. Within ten minutes, you are ready to start buffing and polishing.

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

Quite Toxic

Most of the downsides of this product 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 product indoors. In addition, there are some questions about whether or not this product 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 product by mail. Obviously, it depends on where you live, but shipping costs are likely to be higher no matter where you are.

Tenax Stone Sealer Tech Sheet PDF

Pros
  • Excellent coverage
  • Very inexpensive compared to most others
  • Dries quickly (within ten minutes)
  • Provides exceptional moisture resistance
  • Only needs to be applied once
Cons
  • Very toxic
  • 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 – 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 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 Use

This product 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 product 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, and limestone. This product 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 product 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 product to clean not just your kitchen countertop but, on showers and floors too. Make sure that you have wiped the surface clean first before you apply this product. Don’t forget to allow this product to dry first to avoid streaks. It is advisable to use microfiber cleaning cloths to get maximum results.

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

12. Tenax Ager – Color Enhancing Sealer

If you are trying to find ways to preserve the color of your granite countertops Tenax Ager is just for you. This product could intensify the beauty of your granite by giving the countertop a permanent “wet” look appeal. This 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 product 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

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 product can improve the color retention if you use it in rough, sanded or flame textured granite surfaces.

Solves Color Mismatch

To solve the edge color mismatch this 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 sealant.

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

Pros
  • 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
  • Available in Packs of 1 to Packs of 4
Cons
  • 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 – 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 product is a penetrating sealer that forms adjustable molecular links to effectively protect the granite and stone countertops.

What Makes This Unique

Unlike coating sealers, this penetrating 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 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.

Works on Travertine

This product works on rough travertine or limestone. Don’t forget to follow the directions found on the bottle. This 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 product could be a good product for some stone 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.

Pros
  • 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
Cons
  • 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. Stone Pro Pro Sealer – Great Protection Against Oil and Water

Pro Sealer works as a multipurpose impregnating 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.

Cheaper Alternative

I can say that Pro Sealer is sold at a less expensive price than most solvent-based 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 product is actually watery which will make it easier to apply. Since this product is water-based there is no need to dilute it in water. You just need to follow the directions on the container.

Doesn’t Leave Bad Odor Fumes

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

Easy Application

No scrubbing 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 product does not leave a residue or streak. It will take from 24 to 72 hours in order for this 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.

Pros
  • Long-lasting 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
Cons
  • Level of stain is not as good for marble surfaces
  • Not allowed to use heavy soap and products because of too much surfactant
  • Must be reapplied after six months 

15. More Premium Stone Sealer – Works Best on Natural Stone and Tile Surfaces

More Premium Stone Sealer protects the countertops by enhancing the natural stone.  This 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 product 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 indoors and outdoors.

Works on Most Surfaces

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

Safe and Effective

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

Makes Cleaning Easier

This product 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.

Keep the Room Smelling Fresh

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 product.

Pros
  • Natural Stone Color Enhancer
  • Easy spray-on application
  • Subtle scent
  • Does not leave haze or residue
  • Creates an impenetrable barrier against stains
  • Safe for food preparation
Cons
  • Provides surface care only
  • Must be allowed to dry between 50 to 80 degrees Fahrenheit to get best results
  • Dried longer for some spots
  • Cannot be used on ice stone though

Buyer’s Guide

Stone sealing is the process of applying surface treatment to products made of natural stone to stop the process of staining and corrosion. Granite is porous and is prone to damage if unsealed. Sealers slow down the natural rate of absorption but, they won’t completely block stains. Granite sealer will keep the liquid off the surface so that you can easily remove the stain.

What is Granite?

Granite is made of interconnecting mineral crystals. The most common type of granite is feldspar and quartz. People have used granite for thousands of years for different applications. It was once found only in expensive homes but, granite is most commonly used today as one of the most popular materials for countertops. Also, granite is used in bridges, buildings, and other exterior projects. Indoors, polished granite tiles are used for countertops, tile floors, and other design elements. When used on kitchen countertops, granite is far superior to marble.

As a hard igneous stone granite is formed millions of years by volcanic activity. Various natural materials give granite its “crystal-like” appearance. Unlike a diamond that can deliver a story of its own, turning raw granite into a polished countertop requires the use of special tools. Granite can be the best choice for your home remodeling needs. Granite is referred to as harder than a rock. Having heat-resistant properties granite does not easily blister, scratch and chip. It is highly resistant to acid, heat and low porosity.

Advantages of Granite

Granite is resistant to common wear and tear. Granite is a tough and hard material that can resist scratches, staining, scorching and even slicing. Having a granite countertop will not damage your knives. In normal use granite will not easily crack. Besides, you can easily repair cracks using ground granite and a strong adhesive.

Wear And Tear

First, even when you use the best quality granite, this stone can easily lose its elegance.  Granite has tiny holes sealed into the compound where oils and stains can seep in. You must make an effort to protect it using a granite sealer. Before using the granite sealer you must clean and polish the surface first.

Resistance to Heat

Second, even when you subject granite to temperatures as high as 480 ºF up to 1,200 ºF, granite can withstand heat. However, to avoid potential damage you should not subject this stone in extreme changes in temperatures. Avoid placing something cold on the granite counter after you place something hot in the same area.

Stain Prevention

Third, just a simple reminder not to allow coffee, wine, oil, and similar substances to stay long enough since these will cause stains. Sealers do not prevent stains completely but, using these sealers will make it harder for stains to saturate the granite. Stain protection depends on the granite or marble countertop.

Minimal Time to Clean

Fourth, when granite is sealed, you don’t have to spend a lot of time to clean up. You can easily wipe out dirt without the need to scrub. You will only need dishwashing soap and rinse it well. In case, there are some spaces that have residues you can use a small amount of acetone. Wipe the excess solution using a clean cloth.

Typical Uses of Granite

Granite is one of the world’s toughest materials. Have you ever wonder why granite is used for monuments. This is because granite can last down the generations. Before power tools were discovered, carving granite was a difficult process. This is the reason why this stone is often reserved for use on very important projects. Granite is used indoors and outdoors.

Indoors

In terms of indoor use, granite is primarily used for kitchen countertops. Granite can be used on kitchen and bathroom floors in homes and commercial buildings. Granite has two kinds of finishes: polished and honed. Polished can be easily identified because of its mirror gloss sharp reflection properties. Honed, doesn’t cause reflections. Honed finishes can be used for bathroom and kitchen countertop.

Outdoors

Because of its ability on low water absorption and being scratch-resistant granite is used for patios. Granite is ideal for outdoor areas. Granite’s durability and versatility make it a common choice for the outdoors. Granite is often used for exterior walls. Its properties prevent granite from suffering from structural damage and water stains.

Flamed finishes are typically used as outdoor paving because this makes the floors slip-resistant. Flamed finishes cause a granite surface to become porous. The intense flame is fired at the stone that causes the granite to become rough. Bush hammered is another type of outdoor finish. The textured finish is created by hammering. This type of finish makes the stone slip-resistant too. Both types of finishes are susceptible to water and “efflorescence”.

Efflorescence Explained

Efflorescence alone won’t cause a major problem by its own. However, this is a sign of moisture intrusion. Mold grows in the presence of high levels of moisture. This can compromise the structural material. Efflorescence is induced by moist conditions, low temperatures, rain, dew and water added to the surface of fresh concrete.

Marble versus Granite

It all boils down to two of the most popular choices of stones used around the home. Granite wins this round because it is harder than marble. Granite being chip and scratch-resistant. Both of these two materials have similarities too. Marble and granite need a significant amount of care. With some extra care, both granite and marble countertops will look fantastic for decades. You can expect a beautiful bathroom, kitchen, laundry, and another office area with any of these two stones.

What is A Granite Sealer Made Of?

Sealers are composed of resin dissolved in water. “Fluoropolymer” as an ingredient is highly resistant to acids, bases, and solvents. Choose water-based “fluoropolymers” that can protect your granite for 5 years or even beyond.  This type of sealer provides you with extra-strong sealing protection.

Light versus dark granite

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 last and perform will depend on your particular stone and sealant.

Penetrating Sealer

A penetrating 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 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 sealer produces sheen in different intensities to highlight and enhance the color of the surface where it is used.

Ideal Granite Sealer

The most ideal kind of granite sealer is a sealant that can offer you the maximum protection for granite, grout, limestone, concrete, marble, travertine and slate. A good granite sealer will offer maximum protection even when you use just one single coat.

Advances in “nanotechnology” has made it possible to use the most advanced and durable sealer yet invented.  The latest technological breakthrough consists of coatings that protect your polished stone surfaces using a clear environmentally friendly breathable sealer.  This type of sealer is ideal not just for granite but for other surfaces that need protection from moisture and stain damage. Better ingredients mean more expensive ones.

Toxicity

First, choose nontoxic granite sealers to do the trick. There are organic or water-based sealer sold online that are better alternatives. Look for products that are 100% natural and does not contain harsh chemicals. Using non-toxic products like this can help you save on as much as 50% of labor cost.

Food safe

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

Countertop Protection

Third, ideally, you can clean your granite countertop using soap and water solution. You must avoid using regular cleaning chemicals because this might strip the seal. Certain chemicals will leave the porous surface of the granite exposed. Don’t use acidic products in food preparation since this can eventually damage the granite countertops eventually. Using hot pan residue from the stove burners can leave burnt marks.

Preserves Natural Beauty

Last but, the least, a coat of granite sealant will help your granite look beautiful. A sealer will prevent water, oils or other forms of contaminant to leave behind a dull and lifeless looking countertop.

Seal or Not?

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 in the countertop. If dark spots appear quickly, this means the stone is reacting to an acid. It also means the stone is either calcite-based or made of limestone. If it takes a minute for lemon to be absorbed, granite sealer is needed to protect the countertops. If lemon doesn’t absorb, there is no need to seal.

Reasons To Seal Your Granite

Granite countertops may be visually appealing but, it is vulnerable to normal wear and tear. Quality granite sealers offer good protection to the delicate stone surface.  When you seal granite this process transforms the interlocking mineral crystals into a source of aesthetic beauty to grace your kitchen or bathroom.

There may be a basis for your concerns about whether you need to have your granite countertop sealed or not. If left unsealed acidic substances can cause granite to deteriorate over time. Stains may result when you use household items like lemon juice, vinegar and similar food substances with color. Sealing the granite is necessary to protect the stone from being exposed to these elements. Over time, water and acidic substances will wear away the seal. Simply put, you need to choose the right granite sealer.

Seal Granite Before Using It

First, there is a need to have granite sealed prior to using it. This means you should seal this before it is installed. 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.

Multiple Coats

Second, it is a good idea to apply multiple coats of granite sealer. You should read the product label since it shows just how much time you need to wait in between coatings. Apply the sealer on areas that are usually exposed to getting wet. These are areas adjacent to faucet, sink, and cooktops. Liquids can easily seep into these areas.

Sealing Existing Granite

Third, 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 cheap granite sealer. It would be better to play safe by having these granite tops sealed immediately.

Misconception

There are things that 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. 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.

Care Guide

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

Daily Cleaning

Step 1, calls for cleaning 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

Step 2, each week, you made need to do a deep cleaning. You need a pH neutral cleaner specifically made for the purpose of cleaning granite countertops. Never use home remedies like bleach, vinegar or any products containing ammonia. These products will destroy the countertop surface.

When to Seal

Step 3, you need to use granite sealer every 6-24 months. Sealing will ensure that stains and germs will not settle into hairline cracks which are common in any natural stone like granite. Installing granite in your kitchen is an investment that will go to waste if you don’t take care of it.

Unused Sealant Shelf Life

Silicone sealant might be durable however, it is not immune ongoing bad. You need to check on the expiration date. Normally, silicone sealant has a shorter life span than other types of sealant. If you leave it unopened for more than 1 year the sealant will harden. Another alternative would be to contact the manufacturer to ensure that you got your facts straight.

Resealing

It’s recommended to reseal granite countertops at least once a year. This is especially true if you love to cook in your kitchen. You need to reseal the granite more frequently if you’re using the countertops on a daily basis.

How to Make Granite Countertops Last

First, select the right granite. Choose a granite that will not easily scratch and stain. The right granite will not be prone to breaking or crumbling like marble.  Bianco Romano granite, for instance, is perfect even in climates with freezing temperatures. This type of granite is available in shades of white and gray and will complement most cabinet color. You actually got the best of both worlds, a type of granite that is sturdy while enjoying its aesthetic beauty for a longer period of time.

Basic Don’ts

Second, avoid using hot pots and pans directly on the countertop surface. However, experts do recommend to use 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 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.

Daily Basic Maintenance

Third, do light daily cleaning every day using a lint-free cloth or paper towel. Use a specially formulated granite cleaner. Finish this off by drying the area using a separate clean cloth or towel. Avoid using abrasive cleaners that can potentially destroy the protective sealant. Wipe up spills on the countertop to avoid potential long term granite damage. Once you notice spills, blot it off immediately using a soft cloth. Clean the area as previously mentioned.  Blot but, avoid wiping since when you wipe this can spread the spill further.

Conclusion

Everyone wants a granite countertop, though not all of us can afford them. If you are one of those who can do so, you definitely want to get the most out of your investment. For such a common stone, granite can be quite expensive, but this is mainly due to the fact that it isn’t easy to work with such a hard stone.

Any of the products listed above are likely to do a good job of protecting your investment for years to come. However, a person should never just scoop up the first available product hoping for the best. After spending all that money on a nice stone surface, it really would be silly to omit the last step, which is waterproofing.

Any of these products 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 product doesn’t try to be all things at once. It simply does one job and does it well.
