Custom-colored Skin veneer plaster wall panels start as 3/4-inch-thick, 4-by-8-foot fiberboard sheets. A layer of water-based plasters and organic pigments is then applied, which is in turn fixed with an acrylic coating. The matte or gloss results range in appearance from linen to glass. 94 Ninth Street, Brooklyn, NY 11215; 718-832-8390; postlogicstudio.com. circle 745
