How to keep paint from peeling in bathroom?

I painted the bathroom 4 months ago due to peeling paint.





Surface prep included scraping, sanding, and priming with moisture resistant primer.





The room was then painted with a bathroom specific moisture resistant paint.





Now it's peeling up again.





The bathroom has a fan that is run during and after showers.





I believe the walls are lathe and plaster.





Looking for painting suggestions so I don't have to do this again in six months.How to keep paint from peeling in bathroom?
There are specific primers and paints for plaster. My guess is these plaster walls never have had the proper primer (then a drying period) and then final coat of paint.


The plaster is transfering moisture gathered in the walls and then it permeates the plaster/primer/paint until it finally blisters the primer and paint off the wall.


Stop by a local Specialty paint store such as Sherwin Williams,Porter or other paint retailer that is geared toward professional painters. They can tell you the proper procedure to remove the existing layers of primer/paint and then the proper prep you need to do to the plaster prior to applying their specific primer/paint for plaster.How to keep paint from peeling in bathroom?
Two reason cause the peeling in the paint .


1-A wet or moist surface.


2- A greasy surface .


In your case dry wall has to be wet cause of vaporization or steam in bath-room .Before painting you should provide a hot air blower with a heater or a fresh air till dry wall completely dry .Other fast action is to patch that section with fast dry plaster .Paint one cote primer white and then any other color that you choose.
If everything was done properly and the paint is peeling after only 4 months , then you probably have moisture getting into the plaster from behind . There could be 1001 reasons why .
Sounds like your vent is venting into the attic... moisture returns to the walls and lifts paint...check that first
