BRICKFORM E-Stains are penetrating, reactive stains that produce unique color effects in finished cementitious surfaces that simulate the natural shadings and aged appearance of stone or masonry. The color effect produced is unique to each stained surface and cannot be duplicated with other materials. BRICKFORM E-Stain creates a chemical reaction within the concrete substrate. This reaction slightly etches the concrete surface to provide deeper and more permanent color. The color value of the stain can be reduced by blending the stain with E-Stain Plus. Special colors can be produced by blending two or more colors together.
