Granite sealer can prevent stains unless you’re sealing granite countertops that specifically should not be sealed (black granite for example). Granite sealers are often misunderstood and misused as a marketing weapon.

It’s generally believed that when a material is delicate and hard to maintain, it needs to be sealed. Why are these granite care products the only ones you should ever use to protect your granite investment? As a fabricator and installer, we always degreased countertops and gave them their final cleaning with denatured alcohol. We have provided this to all our customers as part of a stone care kit when we install a new countertop and when we show them how to clean granite.Sealers for stone (also known as impregnators) are below-surface penetrating sealers, not topical hard shell sealers like those, for instance, that are applied onto wood floors or furniture. They are delivered inside the stone by natural absorption. One of the most important phases of the whole sealing process, is the thorough and complete cleaning and removal of any residue from the stone surface. It should be pretty clear that to work, an impregnator must go into the stone. If you apply it anyway, there’s the distinct chance that some of it will remain on the surface of the stone and it will be affected by spills, giving the impression that the stone is damaged. This damage will appear in the form of “ghost water stains” or “water rings”.

Different granites each have their own needs depending on how porous they are. You can test your stone to see if it needs sealer by putting a few drops of lemon juice in an inconspicuous place. If the lemon juice doesn’t absorb at all, the stone does not need to be sealed. We recommend and use a fluorocarbon alphatic resin sealer. Unfortunately, fluorocarbon alphatic resin is more expensive, but you get what you pay for. If you’re dealing with calcium based stones like limestone or marble, no matter what sealer you use, you cannot avoid the damage caused by acids.

Sealing granite is as easy as spray on, let sit, and wipe off. Should you seal granite and marble tables? I didn’t know what that was, and he told me that’s probably the reason the last countertop got ruined so quickly. Granite and marble countertops seem rather sturdy and long-lasting at first glance, while also being breathtaking to behold. It appears like they will last forever and stay pristine for a long time without much maintenance. However, this couldn’t be farther from the truth. There’s one question most people don’t ask themselves – is granite porous? They just don’t mind too much about spillage on granite surfaces and simply wipe it off with a rag or something similar. Stains are not considered important and are just brushed off – it’s a big piece of rock, how could that do harm? What appears to be a stain on the granite might not be that, but damage to the stone itself. The difference is that stains can be removed – although it is sometimes difficult (see the video below) – while damage can only be undone by replacing that part of the stone, and is usually caused by chemicals or acidic liquids.

That costs far more than you might think. Granite sealers are meant to prevent such damage (and even simpler stains) from occurring. They are usually made from a petroleum-based solvent, or a resin dissolved in water. They work by being absorbed into the pores of the stone and hardening, thus sealing them – hence the name. This process stops spilled liquids from being absorbed deeper into the stone, which gives you more time to wipe them and makes any stains that form easier to remove. There’s the quality of the stone itself, as well as the effectiveness of the sealer, but also how well the sealer is applied. First , you need to clean your granite countertop as best you can.

Then , apply the sealer evenly on the stone and let it be absorbed before wiping it up and leaving to dry for around 48 hours.

Some people don’t wipe the sealer off, which is the wrong thing to do and can damage the stone. All of this doesn’t apply just for granite though, but for other countertops made of different stones, like marble, as all stones are porous to some degree. As noted, all stones are porous, but some less than others.

The less porous they are, the more resistant they are to stains, as it’s harder for them to absorb liquids.

If you apply a sealer to a very dense stone, it doesn’t help keep stains and damaging liquids out of it at all. It only ruins the stone by making stains.

Removing a stain like this can be hard and damaging to the stone, so be careful. You can determine if your stone needs sealing with a simple test. Pour a bit of water on it, watch and time how long it takes the stone to absorb it. If around half an hour or more passes before the water’s absorbed by the stone, or if it’s not absorbed, it doesn’t need sealing. For example , you usually do not need to seal marble countertops.

Sealers do not form a protective shell on the surface of the stone – they just seal the pores in the stone, below the surface. Physical damage to the stone, like etching and scratches, can still occur even when it’s sealed since sealing has nothing to do with that and only protects from stains.

Another common misconception is that they make the stone shinier – this is not true. If you want your stone to shine, you want to get the best granite polish you can get and look up how to polish granite rock. Penetrating sealers are the most standard type, the one that just penetrates the stone and seals the pores.

There are premium versions as well, which protect better from oil based liquids.

Enhancing sealers are a penetrating sealer mixed with a polisher.

They have the usual function of a sealer, while also making the stone nice and glossy. Topical coating , as the name implies, actually makes a protective film on the top of the surface, while also giving the stone some sheen. However, they wear out much faster than penetrating sealers.

After that, there is the life span of the sealer – some last longer than others, and there are even those that last indefinitely and never need to be re-applied. It’s usually marked on the label – for example, “15 year granite sealer” or something similar. Granite sealers can smell , sometimes unpleasantly, and that stink can permeate your kitchen for weeks or even months after sealing, so choose wisely. It’s recommended for use on granite, marble, travertine and similar stone surfaces.

Other claims on the label are that it protects the stone from not only staining but etching as well. Even when applied multiple times, as stated on the packaging, it does not do its job properly. At first, it seems to work fine, but after a few weeks, it’s a different story. Water still leaves stains on the stone if not wiped off very quickly, not to mention any other substances, and acidic liquids still leave etching on the stone.Still, it’s cheap and comes in a large quantity so it can be re-applied at will, and it probably works better with denser stones than mine. In the end, it’s just a simple sealer with no added benefits.

It claims to be usable with any surface made of natural stone. Since it is based on water, it should also have a relatively low odor. Even though the label claims that this is a ‘long lasting’ sealer that is not the case. For granite, it only lasts about a few months before it needs to be re-applied, and even in those few months, the benefits are dubious.


You should seal your granite or marble countertops once every year. Instructions for sealing granite counter top the right way are …

It worked great on my bathroom granite, but no so on my kitchen granite, for some reason. It’s rather greasy as well, so make sure to wipe it off well or it will leave stains on the stone. This is also supposed to work as a cleaner, and that is a function that it performs rather nicely, but it is not such a good sealer. It’s also supposed to work well for re-sealing and doesn’t have any harmful chemicals or bad odors.

It comes in an 18-ounce bottle and is usable with any surface made of natural stone. The good news is that it works rather well, and protects my stone surfaces when applied. It’s also easy to apply, and polishes the granite, giving it a rather beautiful shine that lasts for a long time. However, the protection itself doesn’t last as long, and it needs to be re-applied after a month or even a couple of weeks if it’s a surface that is often used. Thus, you get through the bottle rather fast, and the amount is not large for the asking price. Has barely any smell at all, which is a good point. It also works to enhance natural color and veining making them more pronounced. It is also usable on pretty much any countertop made from natural stone, and it won’t damage them or leave stains as it is made from safe materials.

Well, this is what it claims to do at least.As a cleaner this seems to work rather fine, taking out smaller stains and dealing with some imperfections and damage, while not leaving any bad smells in the kitchen. However, it’s not so good for other applications listed here. For starters, it’s pretty much useless as a polisher as it doesn’t give the stone any shine at all. You’ll still need a proper polisher when using this.

Not good as a sealer either, as it seems to provide no protection despite claiming that it does.

All liquids still stain the stone equally even after applying this product. It claims to make the colors more vibrant, the surface smoother and more reflective while also offering protection from staining that becomes better with every application. It’s apparently safe to use on all natural stone surfaces.

Well, for starters, this is an excellent cleaner as it works well for removing most stains and dirt from stone surfaces around the house. It’s useful as a polisher too, leaving the surface nice and shiny for a long time, even if the granite is regularly used. However, it seems not to be any good as a sealer. Even after multiple applications and using almost the entire bottle up, it shows no effect. Water still penetrates the stone as it did before. Moreover, this is a rather pricey product, considering that it does not work as a sealer at all. It’s a product that has some obvious flaws for sure, especially the fact that it’s a bit costly and needs to be re-applied often. Despite that, it still offers rather good protection while it lasts and polishes the stone up nicely. Because of all that, it has become my granite sealer of choice . I hope my experiences will help you find a good granite sealer for your kitchen countertops . I think that this is probably a good product for those who need to seal their stone products fairly often, like every 6 months or so. Otherwise, you’ll probably end up trashing the leftover product – not very cost effective. Overall, it’s been a somewhat pricey proposition for my granite countertop care but, so far, so good! We need to take care of our granite countertops, while not getting sealers which will last for a short time. Frequent use of the water-based stone sealer maintains maximum surface protection against staining, etching and soil build-up. Now you can quickly and easily enhance the shine and luster of your granite, marble and other natural-stone surfaces.

Whether you’re looking for a sealing product for the first time or a resealer for long-lasting protection, this product can give your granite surfaces the before and after results you want to see. It also works miracles on grout to guard against stains that develop between your shower or bath tiles that can be the most difficult to remove with your hands and a sponge, no matter how hard you scrub. Then share your excitement with your family because that much joy should not be trapped inside. The finish on this nearly white stone is honed (to about ‘satin’) rather than polished. However, the finish was not as slippery as we would have liked. The first pie dough we did wanted to cling to the stone, despite abundant flour under it, too much flour in fact as it started to make the dough overly stiff. Polished stone would have been slicker, but presented the problems noted above. It sprays on wet and beaded on the stone surface, but a clean cloth was used to wipe it in thoroughly to the surface and it wetted out nicely. I put on a moderately heavy coat, rubbed it in and waited for it to dry. It picked up a little bit of shine, water beads on it, it feels much ‘slicker’ than it did. My only complaint is that a smaller offering than 18oz size would have been sufficient – even applying a couple of times a year this is a lifetime supply, a 6oz squeeze bottle without the sprayer at an appropriate price would be appreciated. I cleaned the counters and stone backsplash thoroughly, let them dry. I applied it with one clean microfiber cloth, timed 2 minutes, then buffed with a new cloth. I waited 2 hours and repeated on both the counters and backsplash. We moved into the house with granite installed already and never really liked the color. I read recently that granite needed to resealed occasionally and the lightbulb went off! I cleaned the counters, dried them and applied the sealer as instructed. Holy moly, the granite is the shining star of our kitchen again. It is making me want to repaint the cabinets so to highlight them better.
