Nitoflor DPM is a two-component, solvent-free liquid applied surface damp proof membrane and residual moisture suppressant. After curing, Nitoflor DPM provides a surface membrane with excellent adhesion to damp concrete. Hygrometer readings up to 98% RH within the substrate can be accommodated. This practice should only be adopted subject to a survey confirming adequate underlying ground stability. Moisture testing should be carried out in accordance with BS 8203. Nitoflor DPM is available in red and yellow as a visual aid for application and coverage.
