Can You Paint Cultured Stone Counters?

Remove any fixtures such as faucets and soap dishes from your cultured stone countertop. Clean the counter thoroughly with spray cleaner and paper towels, being sure to remove any grease.

Sand the counter with an electric sander and 150-grit sandpaper to roughen the surface. Work slowly, in manageable sections, until the surface no longer looks shiny and smooth. Vacuum up the dust and wipe the counter with a soft cloth moistened with plain water. Allow the counter to dry completely.

Apply painter's tape over any areas you don’t want to paint. Spray the counter with primer, covering the entire surface, and allow it to dry completely, which will take about two hours (review the primer container label for specifics). Use even strokes and avoid building up too much primer in any one area.

Spray the counter with paint in your chosen color, moving the can of paint back and forth to distribute the paint evenly and avoid drips. Allow the paint to dry completely, then apply a second coat. Follow with a third coat if needed. Use flat, not glossy, paint designed for use on floors; it’s more durable than other kinds of paint.

Seal the paint with polyurethane gloss. Brush the polyurethane directly onto the countertop using quick, even strokes. Allow it to dry completely, and apply a second coat if needed.
