Which paint for a plywood garage

Inside? I'd have said that white emulsion is as good as anything.

You could try 'Ranch Paint', it is microporous and I've never known it peel etc. When we had houses with painted exterior wood (windows, soffits, facias...) I used nothing but.

It isn't cheap but I would imagine it will last 'forever' inside, it lasted years outside.

I used International Ranch Paint. It has a 'silk' or semi gloss finish. No primer/undercoat on bare wood, just a couple of coats.

I would very much expect condensation & mould with single skin. Adding a li ttle copper sulphate, borax or aspirin to paint can majorly help with that. Emulsion would work, OTOH household gloss would be a lot more cleanable. O TOH you'd need to ventilate well for a while after applying it, and during.

I'd be tempted to use backing paper to line it first.

Can't disagree either about ranch paint or gloss. Gloss might benefit from a primer/undercoat. IME modern vinyl silk is pretty easy to clean. A lot depends on what sort of "art". With emulsion, easy enough to wash it over and add another coat if it gets tatty. From "single skin" I was assuming it's a fairly low tech requirement.

made me wonder if the paint needed to be frost-resistant ;)
