- Suitable for use on surfaces with the highest measurable levels of moisture content (up to 98% RH)
- Suitable for use on Anhydrite/Calcium Sulphate based screeds
- 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
- Apply ARDEX K 60 direct without priming
ARDEX DPM 1 C: High-Performance Damp Proof Membrane
ARDEX DPM 1 C is a low-viscosity, solvent-free, two-component epoxy system that forms a robust membrane to manage extreme levels of residual moisture and rising damp. Engineered for fast-track installations, it provides reliable protection on both new and existing substrates, including anhydrite screeds and underfloor heating systems. Its exceptional bonding strength and chemical resistance make it ideal for demanding site conditions, even on fully saturated concrete. Compatible with ARDEX smoothing compounds in as little as 6 hours, it ensures a seamless transition to final floor finishes.
