Flaking paint in Bathroom walls and ceiling

[Mikebh53]

Hi

Son moved into an Ex Army house that had been renovated but the bathroom is a mess please see pictures. I started scrapping the paint off but the areas are getting bigger and bigger. I have read other posts but still not sure what i need to do should i keep going removing all the loose paint with a scrapper? and how do i level the paint out afterwards will i need to seal the exposed plaster and go over any paint that's left?

Any advice greatly apricated.
Mike

Looks like there was no mist coat and hence it’s peeling

Agreed, it looks like someone didn't mist coat correctly.

I am, by trade a decorator. I groan when asked to deal with such jobs. It took the supposed decorator a couple of hours to paint the ceiling, it will take me more time than that to soak the paint and remove it.

In your case, you can mist the missing area (following the manufacturer's dilution recommendations). Use a small rad roller with a short nap. I recommend that because if you use a 9" roller you risk the roller pulling off the old paint as it becomes soft.

I guess you will not want to remove all of the poorly applied paint. Path of least resistance- mist coat/ fill & feather the edges with a soft filler such as Toupret RedLite. Sand/mist coat again. Then use a small roller to paint the ceiling and wall with waterbased eggshell. Once that has cured, you can use a 9" roller.

Alternatives, use a shellac based paint such as Zinnser BIN to coat the whole area (as a primer/undercoat). It is shellac & pigment suspended in alcohol. The alcohol will not activate/soften the oil paint. To clean the brushes and rollers, use household ammonia.

I would scrape it all off. Do it once, do it properly. Then mist cost first before painting...

It’s a PITA but remove.

Yes, continue removing all the loose and peeling paint until you’re left with only solid, well-stuck areas. After scraping, sand the edges to smooth them out so there aren’t visible ridges. Then use a filler to level any uneven spots and sand again once dry.

You should seal any exposed plaster with a primer or mist coat before repainting, and it’s a good idea to prime over the remaining paint as well to create an even surface. Finish with a bathroom paint designed to handle moisture.
