Painting Surface

Plaster

Plaster is a smooth or textured wall finish made from gypsum, lime, cement, or similar mineral binders. New plaster remains porous as it cures and dries.

Plaster paint compatibility

Acrylic, emulsion, milk, chalkboard, metallic, distemper, and some spray paints can work on plaster once it is fully dry and properly prepared. Rigid plaster objects can also accept encaustic when they are absorbent and heat resistant.

Paint Compatibility Preparation Primer or ground Finish Guide
Emulsion paint Excellent when fully dry Let new plaster dry completely and remove dust or loose material. Use the manufacturer's approved new-plaster sealer or first-coat method. Apply the specified finish coats after the sealed surface dries.
Distemper paint Excellent on suitable porous interior plaster Make sure the plaster is sound, fully dry, clean, and free of incompatible modern coatings or loose material. Use only a preparation or size specifically compatible with the selected distemper system. Produces a very matte, breathable decorative finish that is less washable than modern wall paint.
Chalkboard paint Good on sound, fully cured plaster Make sure the plaster is cured, dry, smooth, and free of dust or loose material. Prime porous or repaired plaster when required for an even base. Condition with chalk after curing when the product directs it.
Metallic paint Good when fully cured, smooth, and properly primed Let new plaster cure and dry fully; repair defects and remove dust or loose material. Use the specified metallic-paint primer to create a uniform base. Apply in the recommended direction and method to keep the metallic sheen even.
Acrylic paint Good when dry Let new plaster cure and dry fully; remove dust and loose material. Recommended on porous plaster. Optional indoors; protect if exposed to wear. Acrylic plaster guide
Milk paint Good on fully dry, porous plaster Let new plaster cure and dry fully, then remove dust and loose material. Usually unnecessary on raw porous plaster; previously painted plaster may need primer or a bonding additive. Product-specific; add protection where the surface will face moisture or handling.
Spray paint Good when dry Make sure the plaster is fully dry, sound, and free of dust. Helpful on porous plaster unless the chosen spray paint says otherwise. Product-specific.
Encaustic paint Good on rigid, fully dry, absorbent, heat-resistant plaster Make sure the plaster is fully cured, sound, clean, and dry before applying wax paint. Use an encaustic-compatible ground only when the surface needs additional preparation. Fuse carefully because the support must tolerate the working heat.
