Butterfield CHO Concrete Cleaner, 5 Lb CHO5

CHO Concrete Cleaner is a concentrated citric acid based cleaner that mixes with water and is used to open the pores of concrete while aiding in the removal of efflorescence and other organic stains from the surface of concrete. CHO Concrete Cleaner is very effective for cleaning and preparing concrete prior to staining, sealing or overlaying. The etched surface allows for greater penetration of topically applied coloring materials and sealers, and improves the adhesion of cementitious overlays.
