How to Seal a Soapstone Counter

Soapstone countertops are a popular choice for decorators and homeowners. The name soapstone comes from the look and feel of the stone. Soapstone is available in a wide range of colors including browns, yellows, greens, black, reds and grays along with mottled combinations of colors. Color choices depend on the area of the world soapstone quarries are located. Soapstone countertops are very long-wearing and durable. Soapstone will not damage from heat. Stains will not absorb deep into the soapstone; they lie near the surface. Even with all its resilience, sealing soapstone to protect the surface is a good idea. Sealing helps protect the surface from minor scratches and mars.

Things You'll Need

• Mineral oil or commercial soapstone sealer
• Rags

Instructions

1. Pour mineral oil or commercially prepared soapstone sealer onto a soft, clean rag. Use a pharmacy or food-grade mineral oil.

2. Spread the mineral oil or sealer over the soapstone lightly and uniformly. Continue to reapply mineral oil to the rag and spread it evenly over the countertop until the entire countertop has an oily sheen.

3. Allow the mineral oil or sealer to sit for 1 to 2 hours.

4. Buff the surface with a clean, soft rag to remove excess oil.

Tips & Warnings

• Choose a well-washed flannel rag to apply mineral oil and buff the surface.

• Mineral oil will darken the soapstone surface.

• Reapply mineral oil every six to eight weeks or sooner depending on use.

• Soapstone sealers sit on the stone's surface; they do not penetrate.

• Do not cut with knifes directly on soapstone countertops.
