Tough-Seal WB 525 sealer system is designed for use over interior/exterior conventional and architectural concrete surfaces. This system consists of a fast-curing, two-component water-based polyurethane primer and a finish coat of a high-performance, two-component water-based polyurethane coating. It is an excellent choice when a low odor, high-performance sealer system is required.


With respects to chemical and abrasion resistance, it is equal to or superior to other commercial solvent-based systems on the market today. Tough-Seal WB 525 does not darken the substrate to which it is applied, making it ideal for applications where the traditional “color pop or wet look” of a solvent system is not desired. Due to its high level of chemical resistance, it is ideal for automotive areas. Additionally, it has tire stain resistance equal to conventional solvent-based systems. A low-VOC formulation is available.
