Hi,
I suppose I should really post this in the diy disasters forum, but I need a bit of advice/help.
I've replaced my flat garage roof with a warm deck as it was converted (badly) to a habitable room by the previous owner. I decided to fibreglass the roof to finish it and, not having done it before, I've watched countless videos, read lots of advice and so on. Cue roll of eyes from professional roofers...
The deck is 18mm OSB3 (not T&G) - I've left 3mm gaps between boards and 25mm to the wall of the house; I've taped all the joints and began fibreglassing the trim and joins with 75mm bandage. Unfortunately the deck surface temperature was 38 degrees when I started and my resin started to go off incredibly quickly. I was using 1% catalyst and mixing 1 litre at a time; after 25 minutes my roller was unusable - rock hard. The second one barely lasted 20 minutes. By that time my bandage had fully cured and in most cases I couldn't use a consolidating roller by the time I'd finished wetting out the bandage. All in all, a disaster. My question is, can I remedy the situation? I have some lumps of hard resin and bandaged areas that have visible air pockets in, not to mention pin-holes etc. I've not laid the fibgreglass mat yet; I've covered the whole roof with tarpaulin while I consider the next move. Help!
I'll post some photos in due course, just wondered if a thorough sand and start again on a cooler day (or cooler time of day) would be OK.
Thank-you
-Rob.
