I've just climbed onto my 3 week old GRP roof, I knelt down on it to look at the flashing, when I got up, some of the topcoat was stuck to my trousers..............'that's odd' I thought to myself, so I tested a few other areas and sure enough I can push it about a bit like a thin layer of Blutack. Is the topcoat supposed to be soft n squidgy? I assumed it should have a hardener added to it just like the fibreglass layer.............or am I just a great big old wombat?
