Stone Sealer: What You Need To Know


A stone sealer is a clear protective material or a penetrating sealer that is poured over the face of a tile, countertop or other kind of stone surface. The seal coats the exposed surface with a thin film for protection from stains and contamination, as well as providing increased resistance to wear and abrasion. In addition, it can also make cleaning easier by allowing dirt and grime to be wiped away without marring the stone. Stone sealers can be used use on patios, walkways, driveways, pool decks, countertops, walls, backsplashes and other surfaces where water may come in contact with the stone.

Treating your pavers, stone, slate, concrete, brick, driveways, and garage floors with a wet look sealer will enhance the color of the natural stone and provide a gloss, if that’s the look you are going for.  Other sealers provide a natural untouched appearance.  The choice is up to you!

Two Types of Natural Stone Sealer


There are film forming coatings and penetrating sealers.  The proper way to seal stone is with a penetrating stone sealer as it will pernitrate the stone and protect it from staining, salt degradation, and staining.

Film Forming Natural Stone Sealer

Film forming sealers (wet look stone sealers) appear as a wet-looking sheen and provide gloss on the stone surface. Some stone paver manufacturers like to use it on polished stone pavers.

Film forming stone sealers tend to be more suitable for stone, tile, and masonry surfaces which do not hold up as well as porous stone surfaces to stone sealer penetration.

Film forming stone sealers are applied using a brush, spraying on or roll-on application and will provide protection against soiling, staining, salt degradation, and mild acid etching. Film forming sealers can also be used on other stone surfaces like stone pavers, brick pavers, stone veneer, stone tile, and other various stone surfaces like granite countertops.

Porous Natural Stone and Penetrating Sealers

Stone Sealer: What You Need To Know 1

Penetrating natural stone sealers are available in ‘oil based’, ‘water based,’ and more recently, polymer formulations. Penetrating natural stone sealers are designed to soak into porous stone surfaces like stone pavers, limestone, slate, sandstone and marble to form a protective coating inside the pores of the stone. 

Porous stone is stone that will absorb oil, water and dirt. When stone sealers are applied to porous stone, they soak into the stone’s pores. There are different types of stone that need different types of stone sealers – penetrating or film forming. Generally, natural stones like slate, limestone, sandstone are generally classified as porous stone.

The natural stone sealer penetrates into the stone pores to prevent staining, salt degradation, etching and abrasion of stone surfaces. The proper way to seal natural stone, is by using a penetrating sealer.  They are recommended for exterior applications and for thick, smooth or polished stone types such as granite or marble and will provide long lasting protection.

Solvent Based Sealers


Solvent-based sealers use polymer molecules that are combined with solvents. The solvents help to create a continuous solution. When the solvent evaporates, the polymers will remain behind. Solvent based natural stone sealer contains high volatile organic compounds and are not good for the environment.

Water Based Sealers

Water-based and solvent-based sealers have comparable UV resistance and durability. The real difference is water based paver sealers and stone sealers have low volatile organic compounds and are environmentally friendly, plus you won’t breath in any harmful vapors as you would a solvent based sealer. They’re applied in the same manner.  The major drawback of water-based stone sealers is that they are not as durable as solvent-based stone sealers. The durability of natural stone sealer is often associated with the stone type, thickness and amount used for application. We recommend using a water based sealer.

The Difference Between Sealer Brands

Stone Sealer: What You Need To Know 3

The main difference between stone sealer brands, like at your local stores, is their ability to penetrate into the pores of stone pavers, stone tile, stone veneer, stone brick. Penetrating stone sealers are more expensive than film forming stone sealers because of their increased performance levels on stone surfaces.

Many stone paver manufacturers sell stone sealing products that are specifically designed for their stone pavers.  Natural stone sealer should be applied to the face of your stone surface, stone pavers or stone tile at least once a year unless you are using Seal RX HD or Seal RX Enhance, which both offer a 5-year warranty.

New Stone Installation

New stone surfaces should be sealed prior to installation and stone surfaces that have been recently cleaned, repaired, refinished, or changed in any way should be resealed immediately.

Stone sealers will help prevent stains and make it easier to clean your stone surface by allowing dirt and grime to be wiped away without harming the stone surface.

What Happens If I Apply Too Much Sealer?

If stone sealer is applied to stone pavers and stone tiles too frequently, the stone sealer can fill in the pore spaces which will reduce the stone pores’ ability to breathe, and release trapped moisture underneath your stone pavers or stone tile surfaces. If moisture gets trapped underneath your stone pavers or stone tile, damage from freeze/thaw cycles can be a problem.
