CTech-LLC® LSH™ is the premium hardener and sealer for concrete surfaces. CTech-LLC® LSH™ is a waterborne, lithium-silicate-based, ready-to-use, colorless liquid penetrates into the concrete surface, a chemical reaction takes place, producing a byproduct that fills in the pores of the concrete. This patented formulation when properly applied, offers substantial improvement in abrasion and chemical resistance and will significantly improve the durability of the concrete surface when compared to untreated concrete.
