Excellent video and sound quality.Very impressive product!!
You've now got 3 whisks coated with gluey gunk. It's almost impossible to clean them. I use wood battens as mixing sticks which can simply be thrown away. Saves having a drill outside in the elements too.
Thanks for the video though.
That's what I've always done and just normal black builders bucket with the litres on them, instead of those fancy ones
is this better than felt ?
For an overlay system it is, but I would just strip it and just use their 10 10 products or Cure-It with new osb3 t&g
Can you put felth on a fibre glass ?
Obviously don’t forget that not everything is obvious, obviously
He's most probably taking to people with previous experience with grp/liquid waterproofing
NAH, rip it off and start again.
Load of crap. Just go over it again with sbs two layer felt
This is a quick overlay system. You can't beat classic grp though. Just stip the felt and overdeck with osb3 and fibreglass
@@bradley.h just about every fibreglass roof I’ve been on is leaking due to it cracking. Far too rigid.Only plus is that is looks well. I’ve recovered far too many grp roofs in my lifetime to reguard it as a good roof.
@@user-qz8wp7hy8x Do you mean cracking of the topcoat or base layer. Fibreglass roofs do allow movement for expansion and contraction, however if expansion joints aren't installed or if the foundation is stable this will happen, expecially on warm roofs. It always comes down to the installer
@@bradley.h completely cracked enough for water penetration. Funny you say they allow for movement but I found this is not the case. The weather in uk and Ireland does not suit it. One day can be 3 degrees next day 20c
This is the fault of the installer. The topcoat is UV resistant and if the base layer cracked, they either haven't used suitable matting (600g) or the boarding is wrong. T&g sterling allows moving with spacing between the joins, also expansion joints are fitted at 50m2. I only do fibreglass roofs, and occasionally ponds, pools and wet rooms. If installed correctly, you cannot beat it. This shouldn't be an off-the-shelf product for anyone to buy
Obviously!! What ever you chose to do proper trades, strip and start again, secondly don't use a whisk with anything with a catalyst its a no no, it cooks too quickly. Don't be sold by the confusing buckets they are a complete waste of time and for marketing purposes only, it looks messy, amateurish and just another roofing gimmick.
