Apply to an approximate wet film thickness of 190 microns to achieve 75 microns dry film thickness.
Small areas and narrow sections can be brush applied. Apply with a full wet brush, do not attempt to ‘brush out’ or ‘lay off’.
Overcoating : Maybe overcoated after 45 minutes or as soon as film-dry with all white spirit based finishing coats (eg. Dacrylate Vehicle and Machinery Enamels, QD2, DacSheild, etc.)
Fast-drying finishing coats based on stronger solvents (eg. Dacrylate QD3, QD1, etc.) should be overcoated when primer is firm-dry but within 2 hours, or allow primer to dry overnight.
Note : Overcoating and drying times will depend on ambient temperatures and especially ventilation, air movement, etc.
If allowed to dry overnight the primer should be ideally be abraded to improve intercoat adhesion of white spirit based finishes.
Clean-up : Dacrylate Thinner R5.
