Cold water paints of the casein type might be used either straight to a plastered surface, or the surface area might be first given a coat of primer-sealer to match unequal suction results. The same holds true of resin-emulsion paints, with the recommendations of the supplier of the product being given preference in case of doubt. Because resin-emulsion paints normally have some oil in the binder, they must normally be applied only to plaster which has actually dried completely.

Structure wall paints may also be used on plaster surface areas.
