The Right Bathroom Door Paint ..

[eleanor2]

... with all the steam that a shower creates within! I'm looking at the ideal primer & top coat paint. Are the following two products o.k after an initial sanding of the door? The paint on the bathroom door at present is 'Dulux satinwood mid sheen & hasn't lasted.

Hi, I know it shouldn't make much difference but it may be better to use either both water based paints or oil based and not mix the 2. The topcoat you are going to use comes in both types and unless you are trying to cover up a dark colour can be used without an undercoat using either 1 or 2 coats. Bathroom as the others have said needs to be as dry as possible which can be difficult when people are using it all the time. Tell them that they need to spend less time in there just until you have finished and paint has dried properly. I know you said about sanding the door but make sure you do it well and washing it off with sugar soap may help too as often there could be grease there that you can't see and this would stop the paint from adhering properly.

I just wanted to reply to Nailit's question, eleanor.

Nails, years ago you would have been quite right. Oil-based paint, (usually gloss) would have been preferred over water-based or matt and satin finishes.
Paint technology has leapt forward in recent years. That preference no longer applies.

It really is all about surface preparation. Not just rubbing down, but more importantly, de-greasing. Water vapour (steam) in a bathroom is loaded with body oils and other greasy yuk.
Shedders mentioned a very old traditional product - sugar soap.
It's cheap and easily scrubbed on.
It's still a very effective de-greaser.
