FirmeWash Concentrate

FirmeCrete® FirmeWash Concentrate is a professional-grade etching and haze-removal solution formulated specifically for FirmeCrete Floor & Wall Coatings. Unlike harsh acids that can burn or discolor coatings, FirmeWash creates a clean, uniform sand finish while safely removing laitance and cement haze. It can be used to etch concrete substrates before coating or to open existing FirmeCrete surfaces for Acid Etch finishes. Designed for exterior use only, the concentrate is diluted with water and applied using plastic tools, then rinsed thoroughly for a clean, bond-ready surface.
