I am thinking about painting over the epoxy-coated interior of Little Cat. I would rather not have to do multiple coats of the usual to get adequate coverage over the ply finish. Is there any such thing as an interior paint that gets good coverage in a single coat? I think I saw a post by Boatsmith on this some time ago but can't find it...
We have used household paint for the interior of our boat and it has successfully survived at least 5 years. The UK DIY chains have single coat from the main manufacturers (Dulux I think) and I think I may have used this but can not say so definitely as it was a while ago - I tend to use what ever we happened to have left over from painting the woodwork in the house!
Some stores no longer carry oil based polyurethane porch and deck paint, but if you can get the Glidden product, we have used it inside the boat and also on the deck and it is extremely strong and washable and bears up well at sea on Peace IV. We get ours in Norfolk Virginia at Home Depot for about 25 bucks a gallon. Roller or brush.
The interiors of every boat I have ever owned or built have been painted with quality household exterior latex paint using either a roller or airless sprayer. The advantage of latex is that it allows moisture underneath to escape, but does not allow moisture to flow the other way. Most quality exterior latex paints will last 20-30 years. Using an airless, one coat is all it takes.
Thanks for all the help folks,
Per Ann's comment, Glidden has a porch and deck paint, oil based for gloss, water based for semi gloss. I did use a semi gloss anti mildew paint from Petit in the bilges, but at $40/quart, that's as far as that went once I found the Glidden. Applied with a foam roller.
Confession time. Nev says the ceiling in both hulls was anti mildew interior latex bathroom paint. It scrubs well. But when I paint the companion way ladders, I will use oil based polyurethane porch and deck paint from Glidden. It really takes foot traffic in stride even with sandy feet from the beach.
