No direct from the spec sheet When wood flooring is to be adhered, first prime the cured ARDEX DPM 1 C with ARDEX R 3 E Epoxy Primer, blind the surface with ARDEX Fine Aggregate and allow to cure. Vacuum off the excess fine aggregate to leave a ‘sandpaper’ finish. Apply the relevant latex or water based smoothing compound in accordance with the relevant data sheets. So no to direct bond.

Shame you didn’t use fball or Mapie epoxy dpm. You can bond direct to both. Wonder why Ardex don’t advise it?
