It is possible to challenge stains thanks to a granite sealer. As a result of our long and detailed research, we have listed the five best granite sealers and examined them for you. So, what are you going to buy? What should be your priority criteria? Let’s take a look at our buying guide together now!

Granite Sealer Groups

When you decide to buy a granite sealer, you come across two groups. The first of these is the penetrating sealer; the second is a topical concealer. Both can be water and oil-based. The general characteristics of oil-based seals are that they leave a pungent odor, and the cleaning step is more challenging than water-based ones. You should especially use it on granite surfaces in your outdoor areas. Otherwise, even if you wipe it, the pungent odor will not pass. Water-based seals, on the other hand, are odorless. Some users even say that some water-based seals applied to granite leave a pleasant odor. Unlike oil-based seals, you can also use water-based seals on your surfaces such as tile, onyx, sandstone, porcelain tile, concrete, etc., which do not require the granite to be dry or clean. Knowing the two main categories will help you make a seamless match to the surface you have.

Granite Coating Types

It cannot be obvious to come across many types of sealants. Each sealant has a different structure and properties. Let’s look at the features of the varieties we have explained for you so that you do not waste time on detailed research:

A) Penetrating Sealers

This type of sealant penetrates the surface. It infiltrates the surface of your granite and forms a film on top. Thanks to this film, the body’s water-based stains are not absorbed and cannot cause permanent damage. They do not alter the surface and friction loss (COF) of your granite. Penetrating sealers, which are more suitable for domestic use, also have two scopes. The first of these is standard sealers. Although these concealers do not show durability for a long time, they can protect your granite surfaces from dirt, various liquids, and residues. However, they are not suitable for kitchen type areas as they cannot protect against oil-based stains. The second scope of penetrating sealers is Premium sealers. These sealants provide top-notch and long-lasting protection against all colors, including oil and water-based paints and water dispensers. They are more suitable for domestic and commercial kitchens and are useful in saving you money in the long run.

B) Development of Sealers

They are the sealants that effectively strengthen the natural colors on your stone surfaces and protect your granites without reducing their brightness. These types usually eliminate your aesthetic concerns when you want to get a better appearance. Healing sealants can be expensive as they also contain oil-based and other stain protection properties.

C) Topical Pastes

These types are the ones with the lowest durability compared to other seals. They peel off briefly quickly and are very troublesome as you have to apply them regularly. Although most users prefer surfaces with less usage intensity, it is not a popular coating and is inexpensive compared to other layers.


What Happens If You Don’t Seal Granite?

When granite surfaces are not covered with sealants, the liquids penetrate the stone, creating a dirty appearance. Liquids that get inside over time can also cause malodor and corrosion. Sealants push fluids and prevent them from penetrating the stone.

How Often Should Granite Be Sealed?

With the help of a sealer, you can prevent damage to your granite surfaces. Depending on how light or dark your granite color is, you should seal it every three months and annually. Adequately sealed granite surfaces will not cause you problems for a long time from the first use.

Will Bleach Harm Granite?

Yes, any bleaching chemical that contains acid is not suitable for granite surfaces. Cleaning agents that will be used all the time should be diluted with water. There are some safe special bleaches diluted with water on the market. However, if you have sealed your granite surfaces, it will be sufficient to wipe with hot water and liquid detergents.

Can Lysol Wipes Be Used On Granite?

No, you cannot use it. You should not use it on your granite countertops and your vanity tops or backsplashes because Lysol will cause your sealer to lose its effectiveness due to the hard ingredients and citric acid it contains. Mainly lemon-scented Lysol contains intense citric acid. As we mentioned before, granite surfaces are not resistant to acidic components.

How Do You Clean Granite Before Sealing?

You should clean your granite surfaces at least 24 hours before you start sealing. Be careful not to use hard acids such as vinegar, baking soda, bleach, lemon juice in your cleaning. After completely emptying the surface, wipe it thoroughly with a dry microfiber cloth to remove the dust on it. Take care that there are no fingerprints, oil, or water stains from the surface.


The maintenance of granite surfaces is a necessary process that provides highly effective results. Mostly the unsealed granites will wear and deform over time. Liquid stains begin to penetrate porous granites over time and form permanent stains. That’s why you can protect your granite surfaces only with sealers. Sealers, which you can find suitable for granite on every surface and structure, also have options ideal for every budget. In this review of the five best granite sealers, our preference was for our first recommendation, Black Diamond. We have obtained significant results on all our granite surfaces with this product that provides sealing and protection.
