Bathroom - Flaking paint - PVA?

Hi all,

In the bathroom due to moisture when showering (and the window not being opened) a lot of the paint on the walls is flaking away revealing bare plasterboard underneath.

What should I do to prep the walls prior to painting? I have been advised to flake away any loose paint, sand down the edges where the remaining paint meets the cleared area and then paint with 1 part PVA 2 parts water.

The paint I would use afterwards would be Dulux bathroom paint.

Is this the correct thing to do?

Under NO circumstances use PVA. You will only make matters worse.

DON'T use PVA. Sand down, then seal the surface with Zinsser Bullseye or Bin. Then apply two coats of a suitable emulsion.

I have found Dulux bathroom paint to be very disappointing. Ditto their 'Kitchen paint'.

By far the best paint for condensation/mould-prone ceilings is Zinsser Permawhite.( If you don't want white, it can also be tinted to various colours).

But in the end, the room needs an extractor fan and it needs to be properly ventilated. Is it a rented property?
