Increased bonding and levelling with P500 primer

P500 PU primer is a single component, low viscosity, high solids content polyurethane resin. It has been specifically designed to increase bonding and improve the surface levelling of the substrates prior to the application of the liquid rubber membrane.

Using primer offers you to chance to further ease application and create a stronger installation overall. When tackling large projects, consider using a spray method of applying the liquid product. This gives better coverage too, which can contribute to reduced materials cost in addition to the labour.

Applying the full P500 system, including primer, main coat, detailing with bandage (edges and extrusions) and sealing with a UV top coat can help to maximise performance over the long term.
