Bathroom Paint Peeling

[johnykp23]

Hello All,

I'm after some advice. Our bathroom paintwork had peeled very badly in some areas. I put this down to the ago of the house and the fac the bathroom hadn't been decorated in many years.

We plan to do a full bathroom upgrade, however in the meantime I decided to do a repair and repaint.

The bathroom is small amd had poor circulation and was very steamy when the shower was in use, so I upgraded the fan to the most powerful one I could find.

I then removed all the old paint and filled all the larger cracks with ronseal multipurpose filler amd the small parts with toupret fine filler. I then used zinsser peel stop primer on any old paintwork i couldn't fully remover before finally painting the bathroom with a bathroom paint.

Now, about 6 months later the paint is peeling in some of the areas that the old paintwork had peeled in.

Any ideas what could cause this and how to fix it? Thanks

Condensation.
Make sure the loft above has plenty of insulation as this will keep the surface warm and condensation won't settle on surface.
You need a extractor and open window.
Also buy a cheap humidity monitor so you can see what's going on.

During winter months if you have high humidity around the bathroom and you can't control it then get a dehumidifier and run for a few hours every evening.

Drying towels on radiator and the wet surfaces in a bathroom causes high humidity in that area..
We dry bathroom with squeegee and paper towel.
We dry towels and washing with a dehumidifier in spare room.

You have steamed the paint off, ventilation you have is ineffective .

Thanks for the replies,

It's disappointing as I spent some time finding a powerful fan. Would adding a second fan further along help? Also, the wi down in the bathroom isn't very good amd will eventually be replaced, could the seal cause an issue? As the most peeling is directly above the window? I'll also look at the insulation when he properly redo the bathroom

Is there a sufficient gap under the door to draw dry air into the room. People often overlook this rather vital fact

10mm plus gap under door.
Insulation
Dehumidifier to suck moisture out the property as it's probably saturated.

Watch some of the skillbuilder condensation videos on YouTube.

It's all very simple to understand...

As for above widow problem. That's a cold spot

A second fan could help, I used to have a windowless shower room and I fitted twin vents , was effective .
