Unlike an acid-bases stain, Pure-Stain requires no neutralizing, rinsing, or post-job clean-up. This is because most concrete coatings are more porous than a conventional concrete pore. The pores are already open to eliminate the need for acids to help the colors penetrate. Simply spray it on, let it dry, and seal it. Pure Texture. 336-698-9800. www.puretexture.com
