Larsen DPM One Coat Rapid is a high-performance, single-coat liquid damp proof membrane formulated to suppress residual moisture vapour emissions from concrete and sand/cement screeds prior to the installation of moisture-sensitive floor coverings. Applied as a single coat to the prepared substrate, it provides a reliable vapour control layer without the delay associated with multi-coat systems.

Suitable for use under vinyl, carpet, engineered timber and other moisture-sensitive floor covering systems, it dramatically reduces the risk of adhesive failure, surface bubbling and floor covering degradation caused by residual construction moisture.
