If you're asking whether you can refinish a Stone Plaster wall, the good news is that Earthaus Stone Plaster can be refinished to restore its texture, depth, or overall appearance. The process involves sanding off the existing sealed surface and either recoating with Stone Plaster or rebuilding the system entirely with primer and new coats.
Option 1: Light Refinishing — Sand and Recoat
If the existing Stone surface is sound and only needs aesthetic renewal, a light sanding and single finish coat are sufficient.
Steps:
Use 80–100 grit sandpaper on a drywall pole sander or an electric sander to remove the sealed and burnished layer.
Sand evenly across the surface, taking care not to damage or gouge the plaster.
Continue until the wall appears matte and absorbent.
If the surface has not been sealed, Stone Plaster can be applied directly without sanding.
Wipe the surface thoroughly with a damp cloth to remove all dust and residue.
Reapply Stone Plaster following the Earthaus Stone Finish Application Guide (PDF).
Why it matters: this process removes the hydrophobic seal, restoring surface porosity so the new plaster bonds correctly.
Option 2: Complete Reapplication — Starting Over
If major surface adjustments are needed or the client desires a completely renewed finish, the existing Stone surface can be primed and both coats re-applied.
Steps:
Prime the existing Stone surface: Apply a water-based primer with Earthaus Primer Grit added. This creates a uniform, textured bonding surface.
Apply the Stone Plaster base coat: Use standard Stone Plaster as the first layer to re-establish the desired texture and base depth.
Apply the Stone Plaster finish coat: Follow the Stone Finish Application Guide for application and optional sealing.
Why it matters: starting over ensures complete consistency in texture, color, and sheen — especially when the surface has been significantly altered or damaged.
Additional Notes on Refinishing Stone Plaster
Ensure the existing plaster is stable and free of structural cracks before refinishing.
Always remove all surface dust before applying the new coat or primer.
Refinishing does not require re-priming unless both coats are being redone.
Once refinished, the surface may be left matte or resealed with Olive Oil Soap Sealer for added depth and protection.
