Types of Sealing Products
There are two categories of sealing products: penetrating/impregnating and stone enhancer/coating sealer.
Penetrating/Impregnating Stone Sealers are no-sheen, natural-look sealers that can be water-based or solvent-based and are good for interior and exterior applications. Most quality sealers of this type are rated to protect the stone for several years. A premium natural-look penetrating/impregnating sealer is the standard choice on natural stone countertops.
Enhancer/Coating Stone Sealers are also a no-sheen, penetrating/impregnating sealer that is formulated to darken, enrich, and highlight the natural color and beauty of stone products. They will rejuvenate and improve the appearance of worn and weathered stone. However, they will also darken the color of seams and joints. They are, generally, suitable for interior and exterior use, and rated to protect the stone for several years.
Always reference manufacturers’ literature for specific information on the duration of the sealer’s protection and make sure that the sealer is applied in strict accordance with the manufacturer’s instructions.
Wisconsin Granite does not endorse a specific brand of sealer. However, we do suggest an impregnating stone sealer as mentioned above. We currently use Tenax Pro Seal, but there are many good sealers on the market. Always follow the manufacturer’s instructions.
