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

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

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.

Unfortunately, Polyester Resin cannot be used on Polystyrene as it will eat into it! An Epoxy Resin would be better suited for this application.
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 surface and bed down the new matting. Ensure the glass is... Read more
