If you're wondering whether you can seal Sand Plaster, the answer is that Earthaus Sand Finish can be sealed with Olive Oil Soap Sealer to enhance durability, reduce surface dusting, and create a more wipeable surface. Sealing also deepens color tones and adds a soft, natural sheen while maintaining vapor permeability.
Why Seal Sand Plaster?
Although Sand Finish is often left matte and unsealed, applying Olive Oil Soap Sealer can improve cleanability and protect against surface marking in higher-use areas.
Why it matters:
Creates a mildly water-resistant, wipeable surface.
Reduces surface dusting and micro-abrasion.
Where it's useful:
Hallways, stairwells, or other areas where walls are frequently touched.
Rooms where gentle cleaning or moisture exposure may occur.
How to Seal Sand Plaster
The sealing process for Sand Plaster is similar to the Stone and Marble systems.
Steps:
Allow the plaster to fully dry before sealing.
Follow the Olive Oil Soap Sealer instructions found in the Stone or Marble Finish product guides.
Apply thin, even coats and gently buff to achieve the desired sheen.
Why it matters: proper sealing preserves the natural lime aesthetic while adding subtle protection without forming a film or altering breathability.
Additional Notes on Sealing Sand Finish
For a matte, fully mineral appearance, Sand Finish can be left unsealed.
Once sealed, the finish cannot return to its fully matte state without refinishing.
Avoid using wax or non-breathable coatings over Sand Plaster.
