Ameripolish^® Dye-N-Seal Pro SB concrete dye system is for professional decorative concrete installers. The product was formulated using extremely fine molecules of color designed to penetrate and color most interior concrete surfaces. Dye-N-Seal dye can be used as a stand-alone color application on concrete, or can be used as a base coat prior to acid staining concrete in order to add color to problem areas that will not react to acid stain.
