For a semi-gloss coating, one coat of level wall paint and also one coat of semi-gloss paint ought to be related to the primed surface area. For a high-gloss finish, one layer of semi-gloss paint and one coat of high-gloss enamel need to be utilized over the priming coat.
Prior to using water paints of the calcimine type to brand-new plastered wall surfaces they should be sized, making use of either a glue-water dimension or, if the plaster is dry, a thin varnish or primer-sealer.
Cold water paints of the casein type may be used either directly to a plastered surface, or the surface may be first given a layer of primer-sealer to match unequal suction effects. The same is true of resin-emulsion paints, with the recommendations of the maker of the item being provided choice in case of question. Since resin-emulsion paints normally contain some oil in the binder, they should generally be applied only to plaster which has dried extensively.
Structure wall surface paints might additionally be made use of on plaster surface areas. The benefits of this sort of paint are that layer economically generates a textured decoration and eliminates the monotony of smooth level paint. It likewise covers fractures or patches in the plaster better than common wall paint.
