Bostik Screedmaster Rapid DPM is best buddies with Screedmaster Speed 30 for a combined fast installation of screed.
Screedmaster Rapid DPM is a ready to use, one part, water-based damp proof membrane developed to suppress residual construction moisture in cementitious subfloors and sand/cement screeds.
It has a super-fast drying time of about one hour, which enables quicker access to the site and minimises downtime. Two coats will provide protection up to a maximum hygrometer reading of 95% relative humidity (RH).
No mixing or primer required - just use straight from the 12kg bottle. 2 coats covers up to 40m2.
