Once dry ensure the primed surface is kept free of dust prior to the application of the bituminous membrane.

Drying time

Allow to dry thoroughly before over coating. Drying time is dependent upon ambient temperature, atmospheric conditions and substrate porosity however Xtra-Seal QD Bitumen Primer can be dry within an hour at 20°C.
