How to Paint Over New Plastered Walls
- 1). Cover the floor and any surrounding areas with protective plastic or drop cloths to prevent dripping or spilling the primer and paint.
- 2). Prime the plaster surface with masonry primer or with a mixture of four parts emulsion paint with one part water. Paint on a thin layer of the appropriate primer; you will see and hear the plaster absorb some of the moisture from the sealer. This will prevent the paint from completely covering the plaster.
- 3). Paint the plaster with microporous paint, available from painting specialty stores. Coat the wall in one thin layer of paint, allow it to dry, and repeat with a second coat. These paints do not completely seal the surface, but allow the plaster to continue to breath so the moisture is not trapped.
