Cromar Pro GRP Top Coat

This dark grey Pro GRP top coat is a pre-pigmented, isophthalic acid based roofing top-coat which is fire retardant.

Designed to be applied by roller, this topcoat shows good levelling and sag resistance when applied to an inclined surface. Once used alongside the other products in the Pro GRP  cured you are left with a non-sticky, watertight surface which gives fantastic weather and water resistance and giving you a virtually maintenance free end result.

Applying a liquid layer between 500 – 600 microns to a single ply of 450 g/m² of emulsion bound chopped strand mat will help to create a strong structure, which can then be strengthened by using the optimum amount of orthophthalic acid based laminating resin onto 18mm OSB grad 3 board.

Application: 3-4m² per litre (1-2 coats)

Coverage: 6m² per kg

Curing: Several hours per layer dependant on atmospheric conditions

Recommended to be used with our Pro GRO Glass Fibre roofing system.

Size: 10kg and 20kg
