Gordon Posted September 19, 2010 Share Posted September 19, 2010 Over winter and spring 2008/9 I gave my mirror dinghy a birthday. Having replaced a square in the floor towards the aft end I then decided it would be a good idea to give the whole floor a coat of epoxy resin. "last for ever thought I" The dinghy spent 6 months of 2009 outside covered with a canvas cover. After some heavy rain a small amount of water got in remaining there for a couple of weeks at the most. I was surprised to see that the resin had been attacked in places when the water had stood and was reduced to white powder There were a couple of similar spots on the deck as well. The mirror has spent the last 12 months in my garage at home and today I was full of enthusiasm to have a closer look at the resin. The inspection revealed some opaque patches and closer inspection suggested that it was away from the wood Chipping and scraping away reveals that I can peal the resin off even where it appears to be stuck. So the question is did I make the mistake of resining over varnish, even though it was roughed first, and what to do next I have scraped/pealed it off from the lowest part of the hull ie inside batten as far as the thwart The resin it still looking good behind the thwart I am reluctant to try to remove it all as it would take hours and hours. Any idea why the resin was attacked and did not stick?. Have I got to get it all off and varnish instead. ? Was it bad luck and can I get away with just re-resining where I remove the old stuff. The resin was a new tin of SP 106 The temperature was cold at the time and I put the boat cover over it with a 60 watt bulb burning for a couple of days. Boat was nice and dry having been in the garage for some months and the resin dried hard and was three months inside after the resin was applied Possibly difficult to answer but has anyone any ideas please Quote Link to comment Share on other sites More sharing options...
