Designed for use over concrete, masonry, and polymer-modified cementitious substrates, Mirastain I architectural accent stain is a combination of metallic salts suspended in an aqueous solution that is slightly acid. Its chemical reaction with the substrate results in permanent coloration. The stain accepts most solvent or water-based sealers and can be roll, spray, or sponge applied. All of the 14 colors are UV-light resistant. Miracote div. of Crossfield Products. 310-886-9100.
