Key #804 Acrylic Sealer
Moisture Vapor Control Coating & Flooring System
KEY #804 is a water-based, clear acrylic emulsion formulated to create a clear, non-yellowing, protective coating. Key 804 provides a tough, UV and abrasion resistant film that protects surfaces from moisture, staining, dirt, dust, wear and provides a surface that is easy to clean and maintain. Key #804 is an excellent choice for interior or exterior applications. Key #804 is designed as an effective water-based terrazzo sealer thereby replacing solvent-based acrylic sealers. Key #804 can be used to seal concrete, decorative concrete toppings, masonry, brick, Saltillo tiles, or any cementitious substrate. While it is a clear-drying formulation, it will tend to impart a rich darkening or "wet look" quality to many substrates, especially those of a dark or tinted nature.
