Protect Your Stone Countertops

Sealing is strongly recommended for all-natural stones. It is important to select a high-quality sealer to protect your natural stone. Sealing every 6-12 months will ensure your stone continues to look its best (follow stone sealer instructions to determine how to seal and how frequently to seal). Some types of stone may require more frequent sealing such as marble, leathered or brushed granite, and quartzite. We suggest sealing those types of stones at least every 6 months.

When should I seal my countertop?

A simple way to test your stone countertop to see when you should seal, do the water test. Place a couple of drops of water onto your stone. Observe the drops, do they stay in the raindrop shape and sit on top of the stone, or do they spread out and begin to penetrate? If the water drop begins to spread and penetrate, it is time to reseal your stone countertops. If water is absorbing, then stains can penetrate the stone. For best care, make sure to be proactive with your sealing to prevent staining.

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.
