Different types of Products about the Sealing of Natural Stone

Make sure you understand the differences between the common product types available on the market. The products typically fall into two major categories: Topical Sealer/Coatings and Impregnators.

Topical Sealers are coatings (film formers) designed to protect the surface of stone against water, oil, and other contaminants. They are formulated from natural wax, acrylic, and other plastic compounds. Coatings are classified into two general types: strippable and permanent:

 

Strippable coatings are formulated to be easily stripped or removed from the stone. These coatings are made of polymers such as acrylics, styrene, and polyethylene, and are usually water-based. Many of the janitorial coatings available on the market are water-based, polymer-type products designed for resilient tile floors and not for stone. Read the label carefully and/or consult with the Manufacturer prior to application.

 

Permanent coatings, once applied, are very difficult to remove. They’re made of solvent-based or water-based polymers such as polyurethane and epoxies. These are not normally recommended for stone.

 

When a topical sealer is applied, the maintenance program often shifts from a program focused on the stone care to a program focused on the maintenance of the sealer (for example: stripping and reapplication).

 

If a coating is used on a countertop where food is to be used, verify the coating is approved for food use.

 

Impregnators, water- or solvent-based, penetrate below the surface and become repellents. Impregnators keep contaminants out, but do not stop the interior moisture from escaping. These products are considered “breathable ,” meaning they allow for vapor transmission. They are generally hydrophobic (water-repelling), may also be oliophobic (oil-repelling):

 

Hydrophobic impregnators are formulated to repel only water and water-based chemicals. Fruit drinks, coffee, tea, and soda, for example, would be repelled by a hydrophobic impregnator.

 

Oliophobic impregnators are designed to repel water and oil-based liquids. Cooking oil, grease, and body oils are examples of substances that would be repelled by an oliophobic impregnator.

 

An important distinction between oliophobic and hydrophobic impregnators is that an oliophobic impregnator is always hydrophobic, but a hydrophobic impregnator may not be oliophobic. Be sure to read sealer product labels carefully or contact the Manufacturer to determine if they are hydrophobic, oliophobic, or both.

 

Some products are also labeled as “oil-resistant,” but “oil-resistant” and “oil-repellent” are entirely different. An oil-resistant impregnator will only slow down the absorption of oil into the stone. An oil-repellent impregnator will prevent oil from entering the stone. Make certain that you’re buying the appropriate product for your particular application.
