WAKOL PU-280 MOISTURE BARRIER is a ready-to-use, single-component polyurethane primer designed for absorbent and non-absorbent subfloors. It strengthens sanded concrete edges and effectively manages moisture up to specified levels in cement screeds and concrete, both heated and unheated. Easy to apply with a primer roller, it dries in about 40–50 minutes and offers reliable moisture protection without prior moisture tests on unheated surfaces. Store cool above 5 °C to maintain product quality.
