SEAL & FINISH is an easy-to-use, water base coating that makes concrete surfaces easier to clean and resistant to staining. Its clear, low-gloss finish seals and protects new or existing, interior or exterior horizontal concrete. It can also be applied over or under other concrete coatings or as a protective layer over concrete stains. The final gloss will be determined by the initial porosity of the surface and the number of the coats applied. Multiple coats will produce a semi-gloss finish. SEAL & FINISH does not require acid etching and can be touched up or recoated with simple surface preparation. SEAL & FINISH is not recommended for some areas.
