Cromar Flexiglass Encapsulating Primer 5kg


What is FlexiGlass GRP multi surface overlay?

Cromar Flexiglass is a liquid applied roofing product designed to work on a variety of existing roof surfaces, providing a hard wearing and rapid cure solution. Flexiglass is full compatible with our range of GRP Trims and accessories.

Application of Primer:

It is important that the products are mechanically stirred in the tin, prior to pouring into mixing buckets. Add the required Flexiglass catalyst (after shaking vigorously) and again stir thoroughly for a minimum of 2 minutes using a mixing paddle.

Once catalysed the Flexiglass primer should be applied with a roller or brush at the recommended coverage ratio 200-500g/m2, dependent on substrate. Once the primer has cured and is trafficable, the roof should be inspected for defects.
