Hi all, I'm planning to Coppercoat my 38' GRP sailing boat this year and would appreciate some advice on a couple of points. I don't want to spark off the whole debate about whether or not to Coppercoat, I'm aware there are some strong views but have researched this and decided that for my boat use the advantages make sense. Specifically I'd be grateful if anyone has any advice regarding:
1. Drying out; the boat is currently in the water, I have read that it should be allowed to dry out before treating but I want to keep time ashore as short as possible. Would a week or so out of water be adequate? Also the boat has previously been epoxied below the waterline, does this reduce or remove the need to dry as it is already supposedly impervious?
2. Application conditions - does anyone have any advice regarding conditions at the time of application, eg does it need to be warm, not too warm etc? How critical is this?
3. Blasting - as I have a lot of underwater area and I've heard that surface prep is key, I'm planning to get the hull sand or slurry blasted before painting on the Coppercoat myself. In particular I'm keen that this is done sympathetically enough not to remove the existing epoxy layer. Can anyone recommend a good blaster in the London area? Also can anyone give an idea of what I should expect to pay for this?
All answers much appreciated
