Efflorescence Remover

GST International Efflorescence Remover is used to remove the white chalky deposits, known as efflorescence, found on concrete and masonry surfaces. This efflorescence remover is a water-soluble and biodegradable blend of nontoxic acids and surfactants, which is a safer alternative to the highly reactive muriatic acid. It can also clean and brighten newly placed masonry construction by removing mortar residue and properly prepares surfaces for the application of one of GST International’s contractor-grade protective sealers. It’s also effective in removing mild rust stains from concrete.
