Easy to process Very good flow Dries very quickly Fibre-reinforced Wooden floors can be installed directly to the surface after only 6 hours (layer thickness 3-5 mm), and after 48 hours in layer thickness from 5 to 40mm. When applying on a dry and absorbent sand cement screed or anhydrite subfloor, Wakol D3035 primer should be used underneath to promote adhesion.
