What is the best way to paint a bathroom ceiling?

Best Answer

"There maybe a couple of reasons for your predicament.
Firstly when you applied the dulux specific paint the surface may have been dusty (this stops the paint adhering). Other possible reasons for bad adhesion are wax furniture polish (by accident) concentrated PVA glue(can be used for sealing surfaces), and/or the paint may have needed stirring and/or was dry when applying.
But the most likely reason for the cracking/flaking of the paint might be that in the past an oil based (satin or gloss finish) paint has been applied to the surface and then you have put a water/vinyl based paint on top. This has the effect that up-cycling people are after when trying to give furniture an ”antiquey” look.
As long as you have ruled out past water damage and/or condensation problems (bad ventilation) the solution is to firstly apply a primer/sealer (matt finish) , over which you can apply almost any paint.
As you can see there are many possible reasons for the condition of your bathroom ceiling. I hope that this answer is not too long winded. Trying to cover all bases. :-):-)"

"I would pva the ceiling first then try the bathroom paint."

"Hi,
First of all dulux isnt as good as it makes out, secondly how was the surface before you started to paint? Clean, and dust free? I would recommend removing what you can of the flaking paint and using a pva bond to seal the ceiling let dry and re paint over"

"Damp seal all the ceiling then repaint with soft sheet emulsion"

"You have used the right paint but not prepared the surface properly, sand down old paint and give it two coats of kitchen and bathroom paint and it should be fine
