Ameripolish® SR² Plus is a penetrating stain repellent specifically formulated to protect polished, dyed and non-dyed concrete from oil and water-based stains. The water and oil repelling qualities of SR² Plus provides superior stain protection on most substrates. SR² Plus can be used as a standalone product but, to obtain optimum performance, Ameripolish® SR² Plus is recommended for use with Ameripolish® 3D HS or HSL Densifiers.
