SPD Protector utilizes new protection technology that significantly increases concrete’s resistance to stains, acid etching, and liquid penetration, but remains breathable.

protects concrete floors and enhances the appearance of decorative concrete finishes

"SPD (Silica Polymer Dispersion) is a two-part polymer combined with nano-sized colloidal silica. Colloidal silica bonds readily to the concrete, enhancing the concrete surface and improving the bond of the polymer for more effective stain resistance.  Third party laboratory testing has shown that it extends protection for a duration heretofore unheard of."
