Flowprime DPM is a two-component solvent-free liquid applied surface damp proof membrane and residual moisture suppressant. After curing, Flowprime DPM provides a surface membrane with excellent adhesion to damp concrete and polymer modified sand/cement screeds. Hygrometer readings up to 98% RH as measured in accordance with BS 8203:2001 can be accommodated. Flowprime DPM is available in red and yellow as a visual aid for application and coverage.


Flowprime DPM has been designed for use as a coating over cementitious surfaces which posses high levels of residual moisture or where an integral DPM is not present or not effective. This practice should only be adopted subject to a survey confirming adequate underlying ground stability. Moisture testing should be carried out in accordance with BS 8203.

Flowprime DPM permits early overlaying with vinyl, carpets and resin based products without the conventional “drying out” period being observed. This product is not suitable for use over under-floor heating systems.
