Plaster can be a painter’s dream, or nightmare, depending on how you prep it. Its porous nature means it absorbs paint like a sponge, but skip a step, and you’re left with streaks, peels, or worse. Whether you're working with fresh plaster or revamping an older surface, here’s how to get a smooth, durable finish that lasts.

Understanding common issues when painting on plaster

Often caused by painting too soon on fresh plaster, or skipping the primer/mist coat.

Unsealed plaster absorbs paint at different rates, creating patchy, blotchy finishes.

Using the wrong paint or skipping prep leads to peeling later down the line.

3 tips for painting on plaster

Fresh plaster should be fully dry (pale pink). Sand lightly, if needed, and wipe off dust with a dry brush or damp cloth.

Apply diluted emulsion (70:30 water:paint) or use a plaster-specific primer.

Use breathable emulsion or mineral-based paint. Apply thin, even coats.
