Dove Technology has developed a high performance polyurethane based primer for preparation of weathered single ply membranes prior to subsequent adhering or application of liquid applied waterproofing membranes. The primer is a free flowing liquid providing substantial coverage rate per litre of up to 12m2, making for simple and cost effective application. PVC primer offers long term performance but will discolour if exposed to UV light.
We also have NPVC Primer available for use on new PVC to prepare the PVC prior to detailing PVC single ply systems with liquid waterproofing or for use in hybrid specifications. This formulation ensures that plasticisers do not migrate and degrade the bond strength of the waterproofing or adhered system, it would also be suitable for use over weathered single ply systems.
