A soapstone counter is made of magnesite and talc. Soapstone can be easily maintained and is less prone to staining. However, a soapstone counter can also get scratches, chips, or cracks. The materials you use to repair chipped counters will depend on the size and depth of each individual chip. Typically, the cyanoacrylate-based adhesive is suitable for lighter scratches and smaller chips, while epoxy and pieces of soapstone are necessary for larger chips or corner chips.

Step 1— Prepare the Area

Remove the dust and debris from the counter. Sand the area with a 220 or 330 grit sandpaper or a sander machine. Remove the dust that is created. Some light scratches can be removed through sanding, but deeper chips will persist. Identify the chipped areas and then clean these with acetone and cotton buds. Wear gloves and mask to avoid damaging your skin or inhaling toxic substances. Allow the acetone to evaporate before you proceed.

Step 2— Apply 1 Layer of Adhesive

Cyanoacrylate-based adhesives can be used to repair smaller chips. Opt for liquid glue if the chip is on a horizontal surface. Use gel glue if the chip is on a vertical area because the gel will stay put. Apply a layer of glue in the chip and allow it to dry.

Step 3— Apply Several Layers of Glue

Apply several layers of glue and wait for it to dry between the layers. Apply layers until you overfill the chips in the soapstone counter.

Step 4— Repair Larger Chips

If you identify larger chips on the surface of the soapstone counter, use pieces of soapstone that are similar to the one used for your counter. Break the piece of soapstone into fine particles. Wrap the pieces of soapstone in tin foil and use a hammer to break them. Mix the fine particles with clear epoxy. If your counter is darker, opt for pigmented epoxy. Use the obtained solution to fill the chips in your counter.

If the chip is located on the edge of the counter, make a mold from masking tape to support the epoxy solution until it dries.

Step 5— Even the Surface

If you have used glue, even the surface with a razor blade. Shave off the excess glue from the countertop. Make sure you don’t pull out the glue from the chips. Should you pull out glue, reapply glue and allow to dry. If you have used epoxy, sand the area with a fine-grit sandpaper.

Step 6— Finish the Soapstone Counter

Use mineral oil to finish the surface. Rub the solution employing a towel. The surface may become darker, but it will be more resistant to heat and staining.
