ARDEX DPM 1 C Once Coat Damp Proof Membrane

DPM 1 C is a one coat system to suppress residual moisture in lightly shot blasted power floated concrete sub-floors and dense cement and sand screeds. It provides a surface damp proof membrane where a dpm is not present in the floor or it is not effective.


  • Protects the final floorcovering from residual construction moisture and rising damp.
  • Can be applied where a structural damp proof membrane is not present or is ineffective.
  • Suitable for use on surfaces with the highest measurable levels of moisture content (up to 98% RH).
  • Adheres to saturated concrete even at lower temperatures.
  • Can receive ARDEX Smoothing and Levelling Compounds in as little as 6 hours.
  • Suitable for use on cement/sand screeds containing water based under floor heating systems.
  • Apply ARDITEX NA and ARDITEX RS PLUS direct without priming.
