Thorough substrate preparation is essential.
The surface must be free of brittle particles and laitence. Any remains of previous coatings should be removed by means of scabbling, shotblasting and/or diamond grinding.
Important: Free pores must be exposed to ensure good adhesion to the surface.
All water must be removed from the surface, leaving it damp but not wet. DPM Primer may then be applied to the damp surface immediately after cleaning.

Mix part ‘A’ to part ‘B’ in a suitable container, and thoroughly mix for at least 3 minutes. For best results use a slow speed drill with a mixing paddle, making sure all material from the sides and bottom of the container are thoroughly mixed in.
Thorough mixing is imperative as an unmixed product will result in a poor or non-cure situation.

Apply by brush, roller, or squeegee, in one or more continuous applications until the material is absorbed and a film has formed. Make certain that the entire surface is completely covered to prevent water migration.
If the DPM Primer is being used underneath a screed or self level we advise that you apply one coat of DPM Primer to the surface and allow to cure and then apply a second coat with kiln dried sand broadcast into the wet coating to create a key for the screed or self level to adhere to.
Under no circumstances should aggregate be added to the first coat as this will allow water to bleed through the primer and contaminate the following coats. Relative Humidity Required Reading % Coating Thickness 75-85 1 coat of DPM Primer at 200 microns 85-92 2 coats of DPM Primer at 200 microns per coat 92-97 3 coats of DPM Primer at 200 microns per coat.
