Hiya, Amazing video with a lot of information. Thank you. I have a coated fibre glass flat roof which hasn't been maintained for about 20 years. It's not leaking but I want to restore it to prolong it's life. I am getting conflicting info from companies. Some say use acropol some say don't, some say cromopol and acropol would peel off after a couple of years because of the old previous coating on it etc. I am so confused. Can you help please? Thnx
Hi, Thanks for the feedback 👍 I'm not an expert, and have never used any of these type of resin-based fibre-reinforced roof coatings on anything apart from felt roofs, however I can't see that you would do any harm by applying them to a fibreglass roof. If I was doing it, I'd try to make sure that any loose dust and debris was thoroughly brushed off the surface first, and then apply it on a dry day. I know they say they can be applied in damp conditions but .... If you're just doing relatively small patches, you could also try roughening up the existing surface with some coarse sandpaper, to give it a better chance of sticking, but if you're doing a large area then that would be a lot of hard work! Can't say how long it would last. Cheers, Chris
They nearly always use the cheapest felt there is on sheds to keep costs down. I have had same problem with two sheds. One I replaced with EPDM, the other a small shed I used Cromapol as soon as I got the shed and despite 3 coats it still leaked. In the end I used a large roll of Bostik flashband and that stopped the leaks
Totally agree, although I thought we might have got a little bit more life out of it than 18 months or so 😞 Didn't know about Cromapol - looks similar to the Evercryl but slightly lower cost. I suspect I'm just going to end up re-felting it with a better quality felt in the summer, but just wanted to hopefully get a quick repair done in between the (almost) continual rain .... Cheers!
@@handyman-at-home I dont think its that much more than good felt your looking around £50 for a decent one a roll and last around 15 years. EPDM lasts over 25 years and you can easily patch it up if you get a hole just like a tyre
Hi, Yes - still working, although I did end up giving it an additional coat a few days after the video was filmed, as there was still a little bit of water getting through in one spot. After that however, it's been fine. I will probably end up replacing the felt completely either before the end of this year, or if not, then certainly next year. They use really thin felt on these pre-manufactured sheds (the shed itself is great). Cheers, Chris
Fair point - Mea Culpa 🤣 At first it looked like it had completely cured the leak, but then after some very heavy rain I noticed a very small damp patch in just one localised spot. Ended up giving the stripes another coat, and it's been fine ever since. I suspect that the holes from one or two staples in the felt hadn't been thoroughly blocked up by the first coat. Cheers, Chris
