If you're wondering whether you can apply Stone Finish over textured drywall, the answer is that Earthaus Stone Finish can be applied over lightly textured drywall, but surface preparation depends on the depth and type of texture. Proper leveling ensures that the plaster finish appears smooth and consistent once complete.
Light Texture — Apply Directly
Stone Plaster can successfully cover very light drywall texture such as subtle roller or orange peel finishes. These minimal textures are usually thin enough that one or two coats of Stone Plaster will create a smooth, refined surface.
Recommendations:
Clean the wall surface thoroughly before plastering.
Apply primer with Earthaus Primer Grit to equalize suction and provide a mechanical key.
Proceed with standard Stone Finish application, ensuring even coverage and consistent trowel pressure.
Why it matters: light textures can be absorbed into the plaster layer without telegraphing through, preserving the visual smoothness of the finish.
Medium to Heavy Texture — Surface Correction Required
For deeper or more aggressive wall textures, additional surface correction is needed to prevent the pattern from showing through the plaster.
Options:
Scrape down any raised areas with a drywall knife to reduce high points.
Apply an extra coat of Stone Plaster to build up the surface and fully bury the remaining texture.
For heavily textured walls, skim coat with drywall compound, then sand smooth and prime before applying Earthaus Primer Grit and plaster.
Why it matters: uneven or rough textures can telegraph through thin plaster layers, especially under certain lighting conditions. Proper preparation ensures a uniform and professional finish.
Additional Notes on Plastering Over Textured Drywall
Always assess wall flatness and texture depth before beginning application.
Apply primer with Primer Grit to improve adhesion and leveling on any previously painted surface.
Thicker plaster applications may extend drying time — allow full cure before sealing or finishing.
