When solvent-based stain repellants cannot be applied to your concrete surface, Ameripolish SR2 WB is an ideal water-based alternative. This penetrating sealer provides excellent stain repellency in residential, commercial, and industrial applications. Ameripolish SR2 WB provides extreme hydroponic and oil-phobic characteristics for maximum stain repellency while still allowing treated surfaces to breathe. It also protects the treated surface from acidic etching agents. Ameripolish SR2 WB can be used on polished, dyed, and non-dyed concrete. It can be used as a stand-alone product, but to obtain optimum performance, it is recommended for use with Ameripolish 3D HS or 3D HSL Densifiers.
