My mother just called me to say that she is painting her bathroom. She used
a latex primer. When she went back to check the job she noticed a bubble.
She picked at the bubble and some of the paint peeled off. My assumption is
that the previous paint was oil-based. Any suggestions as to how we can fix
Glossy old finish? Washed well before painting? Possibly she used a
fan or heater to dry the paint, or bright sun was on the area causing it
to dry too fast? Blistering is commonly from either suface drying too
fast and solvent trapped under the film, or surface was damp and water
caused the blister. You can pierce blisters and often they will flatten
out and not be a problem. Latex on top of a properly cleaned and dry
alkyd should not be a problem.
Good grief! Don't use paint remover! There are loads of posts on this
newsgroup about removing wallpaper. Just pull off the paper. If you
try to use paint remover, you will have a goshawful mess.
Unless there are many blisters, or the paint is peeling, you may not
have to do anything. If it looks good and stays on, leave it.
You can generally remove paper quite easily and google will give you
lots of hits. Messy but not difficult.
You still should not use paint remover for that. There are products for
removing wallpaper, and their primary target isn't so much the paper as the
glue that held it on. Whatever brand is sold at Home Despot worked for me,
and it's much gentler on your hands than paint remover. No matter what you
use, it's going to take effort and a certain level of cussing.
