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
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.
- Sweep down the roof to remove any debris. We start by bandaging the... Read more
Yes, all Resins, Topcoats and Gelcoats sold by FibreGlassDirect are supplied with sufficient catalyst.
In short, no. The deck would have to be sanded back to the fresh timber and wiped down with Acetone prior to any fibreglass 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... Read more
This depends on the temperature of your working conditions and how much catalyst has been incorporated into the mix. Warmer temperatures will reduce your curing time and colder temperatures will increase the length of cure.
Likewise, adding extra catalyst will speed up the curing process - often necessary for colder temperatures and reducing catalyst will reduce curing - again often necessary during warmer temperatures.
We would recommend mixing no more than 1.5 - 2kg... Read more
