Re: Bathroom ceiling keeps peeling despite sanding, sealing, skim coating.
What is the original ceiling material, plaster or drywall?
What was the original top coat lead based paint, oil based, ???, ?
How clean was the original surface before it was skim coated?
What is he skim coating with, plaster or drywall compound?
Is he allowing this skim coat to fully dry/cure before sealing?
Is he actually using BIN primer?
Is he allowing the primer to fully dry/cure before applying the top coat?
Are the primer and top coat compatible?
Are the primer and top coat new materials or something that's been sitting in your garage for a few years?
From the sounds of the problem, you could have moisture issues in the substrate or something about the original top coat of the substrate which is causing adhesion issues with everything being applied to it now. Moisture issues will have to be corrected before anything is going to stick. Incompatibility issues can be cured when you know what you're working with. Lead and oil based paints don't do well when latex is applied over them, you have to use an oil based primer first, then you can apply latex. BIN primers will work too, but it will take multiple coats of a bin to counteract the "oil on water" effect that lead and oils based paints have with new top coats.
