Application

Substrates must be dry, clean and free from loose particles, fungal growth, oil, grease and other contaminants that may affect the adhesion.

Apply Britannia Universal QD Primer-Sealer followed by the waterproofing system to repaired areas incorporating Britannia Reinforcing Scrim overlapping by 5cm.

For PVC, hypalon, TPO single ply membranes and plastisol coated substrates, it is good practice to inspect and carry out adhesion tests on any existing coating or aged single ply substrate prior to application of the coating. Follow the pull /adhesion test procedure to access suitability of the system. Stir well before use. Do not thin.
