Sealers

STONE SEALERS

All natural and manufactured stones are porous since they are made up of countless interconnected capillary pores through which liquids and gases can move (YES…Natural stone is porous too!).  These porous materials act like a “hard sponge” and actually suck in liquids over time, along with any dissolved salts and other minerals.

What exactly is a sealer?

A sealer is a liquid applied to porous surfaces such as concrete, natural and manufactured stone, or tile, to prevent staining (efflorescence & spalling) from either water or oil-based materials. A sealer reduces the natural absorbency of a stone or material.

Modern stone sealers are divided into 2 types:

Topical sealers

Sometimes a topical sealer is referred to as a coating because this is exactly what it does…. coats the surface of your stone with a protective barrier.  It’s a layer or thin film sitting on the surface of your stone. Generally made from polyurethanes or acrylics. These sealers may be effective at stopping stains but, being exposed on the surface of the material, they tend to wear out relatively quickly, especially on high-traffic areas on driveways etc, and typically need to be removed before a new coat can be applied.  These sealers are typically not breathable, and are not effective against salt attack such as efflorescence and spalling.    

 

Impregnating sealers (Our Favorites!)

These are a type of penetrating sealer, which penetrate deeply into the material, impregnating it with molecules which bond to the capillary pores and repels water and / or oils from within the material. Most impregnating sealers impregnate deeply enough to protect against salt attack such as efflorescence and spalling.   A good depth of sealer is also essential for protection from weathering and traffic.

Kodiak Mountain Stone  initially will be offering two  Acrylic Sealers to our customers for application on natural and manufactured stone applications.

Matte Look Finish VS Wet Look Finish
