We have seriously flaky paint in our bathroom and it's on Dry Lining! I'm guessing that's because when the Dry Lining orinially put up the buidler didn't treat the Dry Lining before they initially painted the walls.
A lot of the paint comes off with a scrapper but there are parts where the paint hasn't flaked and it's very difficult to get off. It also leaves a ridge at the edge of the paint. Is there a way of removing this paint from Dry Lining?
Also, when I've got all the paint off can you suggest what I should use to prime the Dry Lining so that it'll take the paint without flaking?
Dave, firstly, what the heck is dry lining? If it's drywall you mean, the flaking is being caused by steam, which will happen whether the builder primed or not. They used a flat finish which is par for the course in new construction these days. Scrape the loose off, prime the surface with a good latex primer. Then spackle the edges to feather them out. Reprime the patched areas. Then apply two coats of a latex finish with a minimum satin sheen or a specialty bath paint, such as Zinsser Perma-White or BM Bath and Spa. Make sure you dust the surfaces after you sand and don't waste time trying to remove any old finish that is sound, just prime over and spackle.
