Concrete stain protection
SPD Protector provides technology that is reported to significantly increase concrete’s resistance to stains, acid etching, and liquid penetration. Using silica polymer dispersion, the product consists of a two-part polymer, combined with nano-sized colloidal silica, that bonds and shields concrete. The product can be applied to most troweled, burnished, or polished concrete. Applied with a roller, the product is said to dry to 1-mil thickness in about 2 hours.
