Flex Roofing Resin & Catalyst
Polyester resin incorporating flexible additives to provide a low styrene emission, fast wet out roofing resin. This resin is able to withstand thermal expansions, contractions & cures quickly to give a strong, durable Fiberglass flat roof.
Flexible Resin. This helps the roof to withstand thermal expansion/contraction variations, slight movement in roof flexing due to people walking on it and slight movement in roof alignment due to settling.
How to laminate a GRP / Fibreglass Roof
How much Resin do I need?
Work out how much Glass you have by weight and multiply by 2.5. i.e. for 2kg of fibreglass mat, you will require 5kg of resin. Alternatively, use our Materials Quantity Calculator. Roofing applications may require more resin if the resin is applied to OSB3 boards as the boards will soak more resin. Our Read more
Laminating a Fibreglass Roof
Before starting laminating, ensure that the weather conditions will be acceptable. Do not lay the roof if rain is forecasted. Temperatures should be at least 15°C to allow the resin to cure. If the temperature is too hot (over 25°C) the resin will cure too quickly.

Yes, all Resins, Topcoats and Gelcoats sold by FibreGlassDirect are supplied with sufficient catalyst.
How to Repair a Fibreglass Roof Valley
In this instance, a fibreglass roof kit may be used to complete the repair. The first step would be to sand back the exisiting surface to expose the fibreglass and then clean with acetone. Measure the amount of fibreglass mat you will need.
Cut your new fibreglass mat into strips of an appropriate width for covering over the cracks. Ensure there is an overlap of 50mm either side of the crack.
Apply a wet coat of resin to the... Read more
