How Is Roofing Resin Used?
Roofing resin is used in the application of GRP roofing and construction. The exact method you might find yourself replicating will depend entirely on which brand of roofing resin you use, however more often than not the process is the same as, or similar to the following:
- The resin is mixed with the catalyst. The catalyst is the element which causes the resin to harden, therefore it should only be mixed with the resin once you are ready to apply the resin, no sooner.
- The resin is applied generously to the roofing surface. The resin should cover the edges and there should be no air bubbles present for when the matting is laid, nor should there be any thinner areas – the resin should be even across the surface. Consider also that the resin may seep through the roofing substrate, so you may want to add slightly more resin than you think to compensate for this.
- While the resin is still wet the fibreglass matting should be laid onto the surface. The squares of matting will soak up the resin mix so you’ll need to keep adding more until the matting is completely soaked and there is a thin layer residing on top of the matting.
- Next, you’ll want to use some form of roller in order to remove any air bubbles or raised areas of matting before the resin hardens completely. Air bubbles being present can decrease how protective the resin is and may leads to cracks and breakages in the roofing in the future.
