Window reveals collect dust, condensation and hand marks, so they are painted with paint that stands up to regular washing. DIAMOND acrylic latex paints have wet-scrub class 1: silky DIAMOND 15 for smooth reveals, satin DIAMOND 7 hides small flaws better, deep-matt DIAMOND 2 masks uneven plaster. Silky Barvy Pryrody with ready colours is class 1 too, and thixotropic AKRYLTIKS, class 2, does not drip from the roller. Before painting, seal the joint with the frame with paintable acrylic sealant, prime the reveal and apply two coats; wash it after 7–14 days.
