The bathroom is the most demanding room for paint: damp, steam and temperature swings. Here's how to avoid mould and blistering.
The real issue: damp
Ordinary paint doesn't last in a bathroom: steam seeps in, the paint blisters and mould appears. You need a paint designed for damp rooms.
Which paint should you choose?
- An acrylic paint made for damp rooms (anti-damp, anti-mould)
- A satin or enamel finish, washable and resistant to condensation
- For heavily exposed areas (around the shower), favour tiling or a suitable coating
Preparation is decisive
A sound surface is essential: treat any mould, clean up, sand and apply a suitable undercoat. Without this step, even the best paint will eventually blister.
Ventilation and upkeep
- Air the room after every shower
- Check that the mechanical ventilation is working properly
- Wipe down the most exposed surfaces

Frequently asked questions
Can you repaint over blistering paint?
No: you first have to remove the paint that is no longer adhering, treat the cause of the damp, then prepare the surface.
Which finish for a bathroom?
A satin or enamel finish, which is more washable and more resistant to damp than a matt paint.
