renovating varnished sidedecks - moved from dinghy

   Rupert,

I suspect Ive exactly the same problem.  The modern GP has painted decks and with the underside just primer or bare so any damp has come up through the decks and trapped under the cover just sits under the paint and delaminates my decks.

Ive made sure the underside is paint and swapped to an old fabric cover.

	I've been having trouble with lifting varnish on the Minisail this winter. The boat has one of those black plastic covers, and I'm sure it is to blame, so I've just spent more than the boat is worth on a breathable cover. It arrived today, so I'm going to go and see if it fits tomorrow.

	S, Nothing much has changed your in much the same postion really. The problem you have that any primer will now darken it so unless you do the same thoughout its gonna look a bit funny. I dont understand why its lift to so quick, my varnish was in good nick this year with such a wet summer, painted decks suffered a bit from the damp collecting under the cover though. Kev

	Well just to resurrect my old thread, I ended up taking the decks back to wood pretty much all over and varnished up with 2 coats of thinned international original, and then a couple of coats un thinned. It seemed to come up pretty well, I also ended up spending more than the boat cost on some new fittings (dont tell the wife!) Anyway, the kids really enjoyed the summer - which was the point. I planned to put the boat in the garage before christmas but ended up moving house in feb so it only came home last week. Unfortunately, parts of the Topsides have deteriorated again, particularly the foredeck which was the worst area previously. The varnish had started to lift a bit again, so I want to fix it better this time. I wonder if it would be better to use nitromors to clean off the old damaged varnish - rather than sanding as I did perviously and possibly using a clear primer instead of thinned varnish. grateful for tips s

	If you use a roller and get bubbles, waggle a heat gun over them (100 to 200mm away from the varnish) and they pop. Obviously you need to be careful with heat guns and boats but it works and is quick. Also works with epoxy.

	I would make good for now and go sailing. If you have somewhere dry to work on her in the winter then that is the best time to do it. I am always tempted to rush things when the weather is good for sailing.

	So, I got the boat home last night and it doesnt look as bad as the pictures had suggested. There are patches where the varnish has started to lift and other areas where it seems pretty solid. The wood seems to be pretty fair for a 30 year old boat. Unfortunately the transom is painted rather than varnished, which I dont really like, I am tempted to strip , this but am a bit concerned that it might uncover some unpleasantness. Perhaps I will leave that for now, and just get with getting it on the water. I'll see how the day goes, but I am considering removing the old flaky bits, then building up these areas to match the good bits of deck, before overcoating the whole lot, with a view to doing a whole repaint next winter. Do think I would really be better biting the bullet stripping off the whole lot from the decks now and be done with it?
