Interior Painting Advice (plywood and pine)

[chibb]

We're fitting out a small steel sailing boat (Tom Thumb 24), and getting thoroughly confused about what to paint the wood with. We have some bits of pine framing, and mostly marine plywood.

We would like to end up with it mostly painted a light colour (magnolia?) in a satin/silk finish so that it doesn't show the imperfect job we've done on it. And pick out a few areas in varnish.

I'm reasonably happy that we'll probably be doing something like: Knotting solution->Primer->Undercoat->Topcoat )although some primers claim to be self knotting!)

Having looked at various paint manufacturers websites am now perplexed about what paints to use - interior? (might wash away in the boat ;-)) exterior? (contains fungicides that might not be nice to sit against). And then there's water based/alkyd based/latex based????

Thanks in advance for any advice.

I use a Dulux exterior paint. All seems fine after 5 years /forums/images/graemlins/smile.gif

If the inside woodwork got wet then I'd have more things to worry about than which paint I used. If it's good enough for 5 - 10 years outside in the British climate then I reckon it's fine in my saloon.

I had the same problem.

36 year old boat, too much dark wood inside, too many old screw holes, redundant fittings to be removed, a mixture of plywood and other woods.

I removed the old stuff, filled the holes with B&Q wood filler, sanded down the whole lot, dulux undercoat then Dulux Exterior gloss. (light blue)

Done earlier this year so I have no idea how it will last but it looks great now.

I would definitely use knotting solution on the pine - primers that claim knotting properties are only half way there. Primer is essential but undercoat less so unless you need to cover dark coloured primers. Undercoat will also help (a little) to fill surface imperfections but if you are filling anyway that is a better way to get a good finish. Unless you want a high gloss, acrylic (water based) paint will be better as alkyd tends to yellow in artificial light. Just take care it does not get wet in the first week or so after application
