I am repainting a bathroom. Previous
owner painted latex on top of oil based.

Want to repaint with latex but concerned
with peeling.

I have been told I have to sand off all
the latex paint then start with a primer.

Is this the proper way? Is there an
easier way? Please offer suggestions?
Does ALL the latex have to come off,
or just roughed up?

willj, This can be a tough one. If the latex doesn't come off very well it will leave you wondering if problems are in your future. This is what I would do. Using water, sponge or spray with a garden sprayer keeping the latex wet for a peroid of time. Using a coarse scrubber should break the paint loose and help a great deal. If you really have a latex over oil situation sanding or any other prep will not help prevent trouble as time goes by. I share your pain and concerns due to my 70 year old home being freshened up by a bum with a gallon or two of cheap Walmart paint right before I bought it. You guessedit, he put it right over 70 years of fine oil based enamel. Some I removed as described above and other areas I KILZed and hope for the best.....Mike

I've never had any problem with latex over oil. As long as the paint surface is sound now, it should not present a problem in a bathroom, since it has worked for me on exterior applications.
