Mouldy Bathroom Ceiling - Bought Too Many Products

Postby Jeemy » Fri Aug 23, 2019 2:50 pm


I hope somebody can advise me how to continue this project I've started.

The bathroom has no windows, its our ensuite.

I'm refurbishing said bathroom, which was starting to get really bad black mould on the white plasterboard ceiling and cornices. In addition the paint was flaking off the walls & cornices from damp and there are a few cracks in the plasterboard paper (?) covering.

So I got some advice from old threads and took everything off the walls - mirrors, cupboards etc, so I could ensure any hidden mould was treated, and washed the whole lot down.

I then treated it with HG Mould Spray, leaving it overnight, washing it all down hot, then drying it for a day. I sanded all the bad paint, then used the mould spray again, treating again for 30 minutes and washing it down hot.

Then I cut all my holes in the ceiling, fitted a much better extractor fan with a timer (previous one barely extracted and only worked with the lights on) and left it for a week. We haven't used it to shower, but nothing appears to be growing back so I am pretty sure I'm just left with discoloration.

The trouble is I've bought so much stuff, I'm not sure in what order to apply it.

Here's what I've got:

Zinsser Gardz primer/sealer - actually bought to treat the areas behind the radiators where they were clearly used to dry clothes all over the house by the previous occupiers. But I have it if its useful for this.

Ronseal White Anti-Mould paint - to do what it says on the tin.

Everbuild Filler Coat - to cover all the flaking paint and hopefully give a smoother surface.

Dulux white emulsion - again not really for this project, but I have it.

So my gut instinct is to paint the anti-mould paint on first, then use the filler coat, then finish with white emulsion or the Ronseal again.

Does anybody have any advice as to what order I should put all of this on to ensure the best longevity?

I need to paint the ceilings, cornices and walls down to the tiles which are tits-high, and all of them need a bit of filler to smooth them. I do have some Polyfilla also.

Thanks in advance!

I am guessing an answer now will be too late for the OP but I am desperate for an answer to pretty much the same question!
I am about to repaint a bathroom which has both stains and peeling paint on the ceiling. I've bought the following but am not 100% sure which to use first. I think I know... well i know which way round would make more sense to me but if anyone can confirm then it would be great!
I bought..
- Zinsser Peel Stop Binding Primer (to bind the peeling paint and prevent further peeling)
- Zinsser B-I-N Primer Sealer Stain Killer
In my wee head it makes more sense to bind the peeling edges of the pain first, then seal the stains but can anyone te me if this indeed the right way round??
