CP-WE Polymer-Modified Water-Based Epoxy Primer

CP-WE

CP-WE is a polymer-modified water-based epoxy primer and sealer that prepares non-porous surfaces such as moisture remediation barriers, ceramic tiles, metals, well-bonded cutback adhesives and plywood or OSB surfaces for the application of an appropriate CUSTOM® self-leveling underlayment. It seals porous surfaces and improves the bond of the underlayment to the surface.
