How to Seal Soapstone Countertops

Make cleaning and maintenance of soapstone countertops easier by applying sealer.

The metamorphic rock soapstone has a wide variety of uses, including sinks, bowls, baking decks for ovens, and countertops. Soapstone is an ideal choice for countertops due to its long-lasting durability and vast array of color choices. Countertops serve as places to perform many tasks within the home, many of which may damage the surface of soapstone if left unsealed. By sealing a soapstone countertop, you will add extra protection from everyday wear and tear, minor scratches and surface staining.

Things You'll Need

• Dish detergent
• Wooden spoon
• 2 clean sponges
• Clean towel
• Stone sealer
• 2 soft cloths

Instructions

1. Fill the kitchen sink with warm water. Add three to four drops of dish detergent to the water. Use a wooden spoon to stir the water until soap suds develop.

2. Dampen a clean sponge with the soapy, warm water and wipe the soapstone countertop to remove dirt, oil and grease.

3. Empty the kitchen sink and fill it with clean water. Dip a clean sponge into the water and rinse away the soap residue left behind on the countertop.

4. Dry the soapstone countertop with a clean towel, or allow it to air-dry.

5. Pour stone sealer formulated for use with soapstone into a small bowl. Dip a portion of a soft, clean cloth into the stone sealer.

6. Wipe the stone sealer over the soapstone in a light and uniform layer. Continue to dip the soft cloth into the stone sealer and rub it onto the soapstone countertop until every inch develops an even color and sheen.

7. Allow the stone sealer to remain on the soapstone countertop up to two hours or as directed on the sealer's label.

8. Remove excess sealer from the surface of the countertop with a clean, soft cloth. Use the soft cloth to buff the countertop in circular patterns.

Tips & Warnings

• Sealing soapstone is optional. Since scratches and stains cannot penetrate deeply, sealing soapstone will aid in faster maintenance.

• Unlike marble or granite, which can absorb stains deep within, soapstone is nonabsorbent. Stains will stay on the surface without penetrating deep within the stone.

• If you choose a cleanser formulated for use on soapstone products, read the directions carefully; some manufacturers may require the cleanser diluted with water before use.

• Avoid using cleansers containing abrasives, acids and alkaline chemicals on a soapstone countertop, as these will scratch and damage the stone.

• Never cut directly on the soapstone countertop. Always use trivets and cutting boards.
