How long do I mix the catalyst for?
I have a small bay window that I want to use the GRP roofing system on and want to know how long should I mix the catalyst in the resin and topcoat before I apply and how can I tell if it's been mixed correctly?
Once you've measured out the correct amount of GRP roofing base resin or finishing topcoat into your mixing bucket, add the desired amount of catalyst using the special measuring bottle or syringe and then you'll need to give it a good mix for at least 2-3 minutes making sure to get in all the corners.
The Fibrelast system has a special colour change indicator which will turn the resin from a blue to a deep green to indicate the mixing is complete and you're ready to apply.
