Bostik Hytec A370 Rapid DPM (12kg Polyjerry)

Recommended Professional's Choice - LOWEST ONLINE PRICE - Bostik HYTEC A370 RAPID DPM is a ready for use, one part, waterbased damp proof membrane. It has been developed to suppress residual construction moisture in textured and absorbent cementitious subfloors, concrete and sand/cement screeds. It is not recommended for use on dense compacted or profiled floors or subfloors without an intact base DPM.

Bostik HYTEC A370 RAPID can also be used on heated sand/cement screeds with a confirmed moisture level not exceeding 90% RH when tested in accordance with BS 8203. Underfloor heating must have been fully commissioned and any cracks, damages etc. in the subfloor fully repaired. 

It has a 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).
