DPM Primer XFH is a solvent-free, low viscosity, high solids content twin pack epoxy resin with water-reactive and oil binding properties. Designed for application to open pored damp and oily surfaces, DPM Primer XFH is highly resistant to rear side soaking from both oil and water, allowing the most difficult of floors to be coated.

Thorough substrate preparation is essential.
The surface must be free of brittle particles and laitance. Any remains of previous coatings should be removed by means of scabbling, shotblasting and/or diamond grinding or steam cleaning.
Important: Closed 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 XFH™ may then be applied to the damp surface immediately after cleaning.
Mix only as much as can be applied within the pot life (see ‘Pot Life and Curing Time’). Add 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 and a homogeneous mix is obtained.
Ensure thorough mixing 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 oil or water migration. Oil or grease impregnated surfaces should be primed using a paintbrush or soft sweeping broom to work the material well into the surface.
Under no circumstances should aggregate be added to the first coat as this will allow oil to bleed through the primer and contaminate the following coats.
If the period between the application of the primer and relevent top coat will exceed 24 hours, then a second coat of primer MUST be applied with fine kiln-dried aggregate sprinkled evenly over the WET second coat at a rate of 1kg per m² to provide a key for the final coating. Spiked shoes should be worn to avoid disturbing the wet coating. Allow to cure for a further 24 hours before removing all loose aggregate from the surface, which is then ready to receive a suitable top coating (Flortex EP/Flortex Professional/Flortex Chemical Coat).
If time is very limited – the following method may be used, but this is not advisable for very damp or heavily contaminated substrates: The first coat of DPM Primer XFH™ may be over-coated within 4-12 hours with an appropriate top coat (Flortex® EP/ Flortex® Professional/Flortex® Chemical Coat). To ensure chemical bonding between DPM Primer XFH™ and the over-coating this interval should not exceed 12 hours. Allow to cure and re-coat if required: see appropriate coating Data Sheet.
