Hello!
We have renovated our upstairs. The ceiling in the bedroom has a somewhat inadequate air gap, and the hallway completely lacks an air gap. Fixed it as best as possible, added a moisture barrier, but it's doubtful it will be 100% tight without any leakage. Would it be smart to paint the ceiling & walls in the bedroom with wet room paint (alternatively, wet room paint primer and then regular paint over it)? I saw a claim that the paint would be toxic for 6 months, but without evidence of that.
Thanks for the input!

I don't think you'll gain much from it, wet room paint is hardly much more dense compared to a few layers of regular ceiling paint. It's basically the same chemistry in both paints, it's an acrylic suspension - a latex paint.
Significant leakage of moisture to the attic rarely occurs directly through painted layers. Look along the room's corners and the ceiling-wall angle instead. Often large gaps behind the moldings.

Your question is quantitative; I guess in quantitative terms, wet room paint is much denser than, for example, matte ceiling paint. But the question is more whether ceiling paint isn’t in absolute terms dense enough to prevent damaging moisture migration. An argument for this is that regular ceiling paint is used in bathroom ceilings, significantly humid environments.eligri said:
Ah, okay!
So it's not much denser than regular 07 wall/ceiling paint then?
I think they tend to be water-based, or are they often latex paints?
Thanks for the quick reply
All these paints are "lattex paints," which is the industry's old-fashioned term for acrylic-based paints. Almost all paints have this chemistry nowadays since the alternative, alkyd-based paints, have largely been phased out.
