Ardex DPM 1 C is a one coat solvent free, low viscosity, two component flexibilised epoxy resin, supplied in pre-gauged units of 6kg, 10kg and 25kg. After hardening, it 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. It protects the final floorcovering from residual construction moisture and rising damp, and can be applied where a structural damp proof membrane is not present or is ineffective.
Ardex DPM 1 C is suitable for use on surfaces with the highest measurable levels of moisture content (up to 98% RH), and adheres to saturated concrete even at lower temperatures. It can receive Ardex Smoothing and Levelling Compounds in as little as 6 hours, and you can apply Arditex NA and Arditex RS PLUS direct without priming.
Ardex DPM 1 C is suitable for use on cement/sand screeds containing water based under floor heating systems. It 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 used as a damp proof membrane that deals with damp concrete where a structural damp proof membrane is not present or is ineffective, with the risk of rising damp. A thinner application may be used to suppress residual moisture in concrete slabs and sand cement screeds which are well compacted and sound, where readings of up to 92% RH are measured. See table below for details. The product is suitable for heated concrete and sand cement screeds. The surface temperature should not exceed 27°C in accordance with BS 8203 and BS 5325.
