Best Granite Sealer
Trinova Granite Sealer is a long-lasting stone sealer which will protect your granite from water and stains. This spray is easy to apply which means it’s a great choice for those who’s never used granite sealers.
For 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. Here is why you need a granite sealer.
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.

Here are the best granite sealers you can get.
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.
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.
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 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.
This is a penetrating granite 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 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
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.
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 improper application.
This is another spray-on sealer, and it offers many of the same advantages and disadvantages that we 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.
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 surfaces.
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.
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 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 Sealer
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 granite sealer which is designed to preserve the natural appearance of 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
Based on the advertising, this granite sealer is especially intended for use on grout surface. 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 stone. Any other type of stone will simply repel the 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
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.
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 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.
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 surface 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.
This is a special-purpose granite sealer that is meant to preserve the natural feel and texture of the surface of 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 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.
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.
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.
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.
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 our 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 sealer, 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 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.
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.
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, and limestone. 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 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.
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.
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.
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.
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 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 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. We 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.
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.
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.
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.
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.
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 concern about odor fumes, this granite sealer may smell a little bit since its 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.
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 sealer does not leave a residue or streak on 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.
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.
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 using 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.
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 sealer.
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.
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.
Stone sealing is the process of applying a sealer treatment to a surface 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 many year 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.
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 surface 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, a surface of this stone can easily lose its elegance. Granite has tiny holes sealed into the compound on a surface 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 surface after you place something hot in the same area.
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 surface. 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.
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 surface.
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 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 granite sealer provides you with extra-strong sealing protection of a stone surface.
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 surface and 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.
Ideal Granite Sealer
The most ideal kind of granite sealer is a sealer 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 granite 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 granite sealer is ideal not just for granite surface but for other surfaces that need protection from moisture and stain damage. Better ingredients mean more expensive ones.
First, choose nontoxic granite sealers to do the trick. There are organic or water-based granite sealer sold online that are better alternatives. Look for sealers that are 100% natural and does not contain harsh chemicals. Using non-toxic sealers like this can help you save on as much as 50% of labor cost.
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 granite sealer chemically un-reactive meaning this will not contaminate your food.
Third, ideally, you can clean your granite countertop surface 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 sealers 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 sealer will help your granite look beautiful. A granite 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, a 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.
Second, it is a good idea to apply multiple coats of granite sealer. You should read the sealer label since it shows just how much time you need to wait in between coatings. Apply granite 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.
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.
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.
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.
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 surface. Never use home remedies like bleach, vinegar or any sealers containing ammonia. These sealers 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 Sealer Shelf Life
Silicone granite sealer might be durable however, it is not immune ongoing bad. You need to check on the expiration date. Normally, silicone sealer has a shorter life span than other types of sealer. If you leave it unopened for more than 1 year the sealer will harden. Another alternative would be to contact the manufacturer to ensure that you got your facts straight.
It’s recommended to reseal granite countertop surface 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.
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 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.
Daily Basic Maintenance
Third, do light daily cleaning of your granite surface 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 sealer. Wipe up spills on the countertop to avoid potential long term granite surface 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.
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.
To see if your countertop surface needs sealing (or re-sealing), just drop a few drops of water on the surface and leave them for a few hours. If your stone is well-sealed, the water will not penetrate the surface of the stone. If you see dark spots where the water droplets were, it’s time to re-seal.
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.
At the same time, you should know that some types of granite do not require sealing. The darker colors of granite tend to be much less porous, and these will not show most stains anyway. Thus, you don’t always have to use a sealer.
For less-porous granite, there are special stone cleaners and granite countertop sealants that can take the place of a sealer. There are also non-penetrating finishes that can improve the sheen and smoothness of your surface without sealing. However, if you are using a more porous type of stone, you don’t have much choice but to use a sealer.
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.
That being said, you need to be careful about sealing your stone when it is wet. When you add a sealer, you are trying to lock moisture out. However, if the stone has already absorbed moisture, you will end up trapping it in place.
Does granite sealer make it shine?
A good granite sealer will usually add to the shine of the stone surface. While there are exceptions, most sealing sealers are intended for this purpose. By doing this, you give the stone surface a more appealing look while creating a perfectly smooth working surface.
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 sealers 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 sealer 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 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.
