Soapstone — common questions

Soapstone is commonly used for Countertops, sinks, fireplaces. Its Mohs hardness of 1–2 and Good freeze-thaw rating determine where it performs best.
Soapstone has a Mohs hardness of 1–2. For reference, granite is Mohs 6–7, marble is Mohs 3–4. Higher hardness means better scratch and wear resistance.
Soapstone has a water absorption of 0.05%. Stones with higher absorption benefit most from a penetrating sealer applied annually. Always test with the water-drop test: if water absorbs in under 4 minutes, reseal.
Soapstone typically costs $70–120 / sq ft installed per square foot for the material. Installation adds $8–$20/sq ft depending on complexity and region. Request current pricing from SmartStones verified suppliers.
Soapstone is rated "Good" for freeze-thaw performance. Its water absorption is 0.05%. Lower water absorption = better freeze-thaw resistance. For northern climates, verify the stone meets your project's freeze-thaw requirements.

How to Care for Soapstone

Essential maintenance steps to keep Soapstone surfaces looking their best for decades.

1

Daily cleaning

Wipe with a damp microfiber cloth. Use a pH-neutral stone soap for weekly cleaning. Avoid vinegar, bleach, or multi-surface cleaners.

2

Blot spills immediately

Blot (do not wipe) any spills to prevent staining or etching. Rinse with water and dry.

3

Annual sealing

Apply a penetrating impregnator sealer to dry, clean Soapstone. Allow 10–15 minutes of dwell time, wipe excess, and cure for 24 hours. Re-seal when the water-drop test fails.

4

Professional restoration

If the surface develops deep scratches, chips, or loses its finish, contact a stone restoration professional. Most damage can be corrected by re-honing or re-polishing.
