Mapei adds to its surface membranes range with rapid drying Mapeproof Primer

August 14, 2020

Mapeproof Primer is the latest addition to Mapei’s range of surface membranes, with the added bonuses of being single component, water-based and moisture suppressing, with very low emission of VOC. 

Ready for use with no mixing required, Mapeproof Primer is quick and easy to roller apply; the primer is green in colour to assist with application, certifying full coverage of cement-based substrates. Suitable for both large projects and domestic installations internally, this Mapei offering also benefits from no waste, and can be resealed and stored with no qualms for future use. 

For particularly porous substrates, Mapeproof Primer should be diluted 1:1 with water prior to a further two undiluted coats, to ensure that the primer penetrates into the surface of the screed. It must be applied in a minimum of two coats over the whole floor at a temperature of above 10°c. 

Upon full application and once dried, the primer provides a waterproof surface membrane, blocking the passing of residual construction moisture from affecting subsequent floorcovering installations, thus allowing early installation of floorcoverings. 

For protection against moisture, use Mapeproof Primer before levelling your floor.
