ᐅ Bathroom: Is paint on the wall sufficient, or is plastering necessary?

Hello

Do you need plaster or wallpaper in the bathroom?

Our house will have "Q2 level finished walls" (outside made of sand-lime brick blocks, inside solid gypsum boards). In the bathroom, we have tiles up to 1.5 m (5 feet) high, and above that, we planned to paint. Now, a painter has offered a cost-effective solution to paint the walls just twice with a breathable dispersion paint, so without applying wallpaper or plaster in between (of course, these can be done for an additional cost). We understand that the surface finish won’t be as smooth as Q3 level finishing / plastering / wallpapering and then painting.

I’m just wondering if this approach is advisable in a "wet room" or if the masonry needs more protection than just 1–2 mm (0.04–0.08 inches) of paint.

Good luck

I wouldn’t use wallpaper in the bathroom anyway. With Q2 and just paint, I think you could see the difference between the skimmed and non-skimmed areas.
I would therefore go for something with texture, like a textured paint or a rough plaster finish. But I’m not a painter, so if in doubt, you should trust their advice more.

Here is how it looks in our rental apartment. Tiled up to 1.50m (5 feet), then a coarse textured finish. The ceiling has a woodchip wallpaper, which I wouldn’t recommend for a damp room.

Hello Zaba12, what exactly do you mean by coarse grain? Roughcast, plaster, or paint with texture?

Well, if I knew that, I could tell you. Unfortunately, I can’t say. For colored finishes with aggregates, it looks too uniform.

Sto-sil filled plaster base?
