Use XPRESS PRIMER H2O PLUS for: Preventing blistering and delamination of coatings due to residual moisture, enhancing adhesion, and reducing efflorescence.
XPRESS PRIMER H2O PLUS is a high-performance, single-component vapour barrier primer designed for use on concrete and mineral surfaces. Unlike traditional primers, it does not alter the surface profile but enhances adhesion for overlaid membranes and coatings. Fast-drying and water-resistant, it allows finishes to be applied within just 1 hour. Its unique colour-changing formulation provides a clear visual indication of when it's ready for overcoating, reducing guesswork and ensuring optimal application.
