Xpress Primer H2O Plus is a unique, one-component vapour barrier primer designed for concrete, screeds, and mineral surfaces. It protects against moisture-related issues like blistering and delamination, while also enhancing adhesion for subsequent coatings and finishes. This fast-drying primer changes colour as it dries, indicating readiness for overcoating in just one hour. Unlike traditional vapour barriers, Xpress Primer H2O Plus does not alter surface properties, ensuring optimal bonding with Gripset membranes, adhesives, and other finishes.
