Centrecoat Strongcoat DPM

Centrecoat Strongcoat DPM is a two-pack, solvent free epoxy based damp-proof membrane for use with the Strongcoat range of surface coatings and toppings.

Best Uses

Centrecoat Strongcoat DPM is formulated to suppress residual construction moisture and rising dampness in concrete and sand/cement screeds. This damp proof membrane can be used in situations where the relative humidity level is above 75%.

Centrecoat Strongcoat DPM is made to be applied by brush or roller in one or two coats, depending on the relative humidity of the floor.

Application

The surface must be clean, dry and free from dust, laitance, oils, paints or other forms of contamination. Grit blasting can be used to remove laitance and surface contamination. For treatment of surfaces containing expansion joints, consult our Technical Department.

Taking care to ensure that the bottom and sides are thoroughly scraped, transfer the entire contents of the Strongcoat DPM Hardener container into the Resin container and, using a paddle mixer attached to a slow-running electric drill, mix for approximately two minutes. Never mix Strongcoat DPM by hand as this could lead to areas of uncured material. Never leave the mixed Strongcoat DPM kit to stand for any length of time prior to application, as this will considerably shorten its working time.

Once mixing is complete, transfer the Strongcoat DPM to a roller tray and, using a medium-pile simulated sheepskin roller, apply it evenly over the surface. One coat of Strongcoat DPM is required where the relative humidity level of the screed is between 75% and 85%. For RH levels between 86% and 98%, use 2 coats.
