Ardex DPM 1C – One Coat Damp Proof Membrane

Ardex DPM 1C – One Coat Damp Proof Membrane is a solvent free, low viscosity, two component flexibilised epoxy resin, supplied in pre-gauged units of 6kg, 10kg and 25kg. After hardening, the Ardex DPM 1 C produces a membrane which can accommodate hygrometer readings up to 98% with high inherent bond strength. Ardex DPM 1 C has excellent resistance to water, grease, oil, aqueous salt solution and dilute mineral and organic acids.


Ardex DPM 1 C has been specifically developed to provide either a DPM, or to suppress residual moisture in concrete slabs and cement/sand screeds which are well compacted and sound, where readings of up to 98% RH are measured. Ardex DPM 1 C can be applied to give a dry film thickness of 250 microns where all surface moisture readings are below 85% RH. Ardex DPM 1 C should be used at a dry film thickness of 350 microns where any surface moisture readings are between 85 and 98% RH Suitable for heated concrete and sand cement screeds. The surface temperature should not exceed 27°C in accordance with BS 8203 and BS 5325
