Unless you’re a world-class chef cooking 7 nights a week with high kitchen traffic you don’t need to seal your stone more than once or twice a year.

If the stone underneath hasn’t darkened then your counters are sealed and you can begin enjoying them! Your post is helpful for everyone who want to know how to seal granite countertop.

Most stone countertops need to be sealed to keep out stains and bacteria. With that in mind – here’s a guide to sealing your countertops. To test the integrity of the barrier simply place a drop of water on your counter for 30 minutes and then wipe away.


We have performed our own tests by creating stains using common foods, condiments and beverages on sealed and unsealed granite. The film prevents either liquid or vapor from passing into and through the stone.

If the pores in stone are completely blocked the stone will not “breath” trapping water vapor in the countertop. Vapor trapped in the stone eventually causes topical coatings to crack, flake and fail. As the liquid is absorbed into the surface of the stone the solids are distributed across the surface. They do this without blocking the stone’s pores and once cured keep food borne particles from adhering to the countertop. There is a misconception that water rings will not appear in a properly sealed countertop. On the other hand there are light colored stones that will darken when water is splashed on their surface regardless of how well they’re sealed. While sealing your countertops does make them more difficult to stain and easier to clean it doesn’t eliminate the need to cleanup up spills promptly.

Many customers have heard that natural stone countertops are difficult to clean and require constant sealing and resealing. Does this mean granite countertops don’t need to be sealed? There are definite benefits to sealing natural stone countertops, especially light colored and porous stones. Sealed granite outperforms unsealed stone when spills are left unattended for 24 hours.

A countertop sealer is a product used to make cleanup easier and protect stone surfaces from stains caused by food borne particles and liquids. Topical sealers are coatings that bond to the surface of the stone forming an impermeable, protective film on the surface. Topical coatings should never be used on natural stone countertops.

Depending on the type of stone this can result in iron oxidation, the appearance of rust colored stains on the surface of the stone or efflorescence, the residue of soluble salts both of which can affect the appearance and integrity of the stone. Penetrating sealers are comprised of a solution and microscopic solids held in suspension. As the liquid evaporates the solids are left behind adhering to the microscopic nooks and crevices in the stone’s surface. The fact is there are certain granite varieties so dense that even unsealed they won’t darken if water is spilled on them. The important thing to remember is that once the water evaporates the stone returns to its normal color.

Once properly sealed, the surface will be more resistant to everyday dirt and spills, which can result in stains and etching marks. However, keep in mind that contrary to the common perception, sealers do not provide an impenetrable protective shell; instead, it gives us more time to clean up the messed area before a stain occurs.

Even though the majority of fabricators do seal the countertops before installing, it is recommended to do a quick test just to be safe. Let the water rest on the counters for five to ten minutes; if you notice that the areas where you applied the water are darkening, it means the surface is letting the water in too fast, and you need to get the tops resealed. However, good care on a daily basis and regular maintenance will determine how that beautiful granite or unique marble island will look like years from the date it was installed.

Whether you have guests over for a wine and cheese night or kids are playing with their colorful markers on the countertops, you can have peace of mind that by just wiping off the mess will bring your stone back to its beautiful look.

Protecting your investment from getting unattractive in a short period of time will cost you less than 7% of the amount paid for the countertops, and it needs to be done once a year only.

Here is how to do it: pour small amounts of water in different areas of your countertop surface. Natural stone countertops are an investment that could last for very long years, if not forever. Getting professionals to maintain your investment in good shape is a smart and cheap decision in a long run.

In its natural form, granite is already strong, durable, and attractive. It is important to properly clean and maintain granite countertops.

Some people seal their granite countertops once every six months to a year, though stone can never be oversealed. As there are varying guidelines, it is important to pay attention to the condition of your granite. Other indicators include dull places on otherwise glossy countertops. Immediately wipe the sealer into the stone with a dry, lint-free cloth, as leaving it to dry can cause hazing.

As a result, people get strong, enduring, and visually pleasing countertops for their homes. If they are not sealed, they would easily be subject to material wear and tear. In fact, it will most likely just stay on the surface of the countertop and leave behind a film of the liquid. As what can be seen, quartz is a kind of material that is virtually low maintenance, unlike its natural stone counterparts. Be careful with the chemicals that can come in contact with your worktop. Ensure that they are not exposed to other chemical products such as paint thinners or cleaning products for kitchen appliances, like over cleaners. Exposing your quartz countertop to extreme heat may also destroy it. In other words, it may be fine when you place your occasional coffee mug or hot bowl of soup on it, but it laying a scorching pot or pan on it for a long time is a different story.

With their durable and aesthetically pleasing nature, quartz countertops have undoubtedly gained some popularity alongside granite and travertine. Even if they are made of different natural stones, quartz, in the completion of its fabrication process, a permanent seal on their surfaces is then created. Meanwhile, marble, limestone, and granite countertops need to be sealed because they are naturally porous. First of all, since it is non-porous, it will not absorb the sealant that you will put on it. On the other hand, doing this on natural stone countertops like marble allows the sealant to permeate the surface of the countertop and fill in the gaps of its pores.

If you want to polish it and make it shine like the first time you got it, all you have to do is clean it with warm water with soap. Even if they are low maintenance, without proper care, problems can still arise.

As a result, you may be faced with dull, unpolished worktops since using abrasive products takes away the shine from their surfaces. Sealing quartz countertops may be unnecessary but this does not mean that they are invincible from the damages that incompatible solutions may bring. It may be heat resistant, but this does not mean that it is heat-proof. As a matter of fact, this can lead to discoloration or burn marks on your precious quartz countertop’s surface. Cutting things on the surface is a big no-no for your quartz countertop. What chemicals can damage your quartz countertops without a sealant? If there is dried gunk, just scrape it away with a plastic tool, such as a putty knife.

In case of grease, wipe this away with disinfectants or degreasing products which do not contain bleach.

How Often To Seal Granite by

How often to seal granite countertops, marble, travertine tile or any stone installation depends on several factors. A few granite varieties are very porous and should not be installed (in a kitchen anyway) because they are difficult to seal at all and may need re-sealing every year. Plus, your slab may have been “resined” to fill in any chips or defects (a perfectly normal process). The only accurate way to determine whether or not any stone needs sealing or re-sealing is to perform the water test for sealing granite countertops. Perform the water test in-between coats to determine when the surface has been effectively sealed and/or if another coat is needed. There’s no explanation of the water test in this article because we’ve explained how to do it in a different article.

Naturally, homeowners want to protect their beautiful, and expensive countertops from unsightly stains.

First, a little stone education will help you understand the answer completely and rest easy with confidence that you know exactly what to do and when. Remember granite and marble are natural products and thus characteristics like absorbency can vary from slab to slab. When a sealer can’t absorb properly, it may leave a haze on the surface that is difficult to remove in most cases. This generality is blandly passed about as if it is an absolute fact. These happen on marble very easily, though, so you may want to determine if you indeed have granite or if it is in fact marble.

It will be true of some granites and some sealers, but certainly not all granite or all stone. Most of what you hear about sealing granite is a broad generality that cannot apply to every case.
