Liqui-Hard Ultra concrete densifier and chemical hardener from W.R. Meadows is a ready-to-use, colorless liquid that hardens and dust-proofs concrete at a molecular level. A surface finished with the product exhibits improved abrasion and chemical resistance, durability, and sheen compared to untreated concrete. As Liqui-Hard Ultra penetrates into the concrete surface, a chemical reaction takes place, producing a byproduct that fills in the pores of the concrete one molecule at a time, eliminating dusting and pitting. With no brushing or rinsing required, the water-based, zero-VOC product is sprayed on and left moist on the surface of concrete for 20 minutes. wrmeadows.com
