How to Repair Cracked Soapstone

Updated February 21, 2017

Soapstone is a relatively soft rock since its primary composition is the mineral talc. This composition makes it an attractive substance for sculptures and ornaments (and sometimes for surfaces), but it also makes it prone to structural weakness. If one of your soapstone products cracks or breaks, it is possible to fix it yourself.

Clean out the crack or break with a damp cloth to ensure the break is clean and ready for the repair.

Use a small paintbrush to apply epoxy adhesive to the crack. This is massively strong glue. Place pigments the same colour as the soapstone onto the epoxy to hide the broken area.

Put the soapstone in an oven. The most effective way to cure epoxy is by putting it in the oven at around 200 degrees Celsius. Take the soapstone out of the oven after 30 minutes, being careful to wear oven gloves to protect your hands.

When the soapstone has cooled, scrape the excess glue off the surface. Any structural weakness from the chip or crack will now be fixed; it is now merely a case of restoring the look.

Use fine grain sandpaper to lightly sand the surface of the soapstone. Work in gradual, circular motions, and keep sanding until there is no discernible difference between the repaired area and the rest.

Polish the soapstone with linseed oil. This will ensure the soapstone regains its original vibrancy of colour and shine, and it will make the repair almost invisible.
