The paint in our bathroom (room dimensions 6'6" x 7') has begun to blister.
The top layer of sand textured paint is blistering, beneath that is a white
plaster-like coating approximately 1/8" thick, and then a pinkish colored
drywall. It looks as though the blistering is occurring along the seam where
two pieces of drywall are butted together.
The three inside walls are the ones with the blistering paint problem, and
all three of those walls have either a hallway or a bedroom on the other
side. The paint on the ceiling and the bathroom's outside wall is fine..
There is an exhaust fan in the bathroom. I do not know what capacity it is.
My questions are:
What is the proper method to repair these walls?
Do I just repair the areas that have blistered, or do I have to strip down
all the walls to drywall?
How do I prevent this from occurring again? Get a bigger fan?
We have lived in the house for 7 years, and this problem only began this
Thanks in advance for any advice
