Pealing paint

A friend had her house painted four years ago, and the paint is coming off
in flakes.

The house had oil paint green originally. It was scrapped, power washed,
primed, and painted white with outdoor latex.

When the pealing chips are examined, the back of the chip is green and the
bare wood can be seen where the chip came off.

It seems that the latex stuck to the primer and the primer stuck to the oil
based.

The house was painted in October in Memphis. I don't know how long they
waited between the power wash and painting. I also don't know if the primer
was oil or latex based.

Any ideas?

I know that the answer is scrape and paint, but wonder what caused it.

There could be two reasons that I can think of. The first depends on the
wood itself. Sometimes the wood is cut quickly and the outside of it is
actually "sealed" by the friction of the saw. If this is true, only certain
boards will be effected. To cure this you need to remove the paint from
these individual boards, sand them and repaint them. Unfortunately the new
boards may be "off" in color when compared to the others. The only other
explanation is that the first layer was put on poorly (i.e.. no primer or
unlearned wood.). Hope this helps!

I meant uncleaned wood.

Sorry for the multiposts all. But you may also want to check for moisture.
If the paint is peeling around a vent, spigot, etc. There may be moisture
coming from the inside as well (radiator, bathroom). To fix this you need
to insert little wedges under the clapboards in a pattern that any decent
painting store (sherwin williams, benjamin moore) can show you. If this is
the case make sure that when you repaint you DO NOT seal the underneath part
of the board. There that's my final answer. Hope this helps.

seems like your original coating is letting go. sometimes puttig a new
coating can cause this. needs to be scraped again real good and painted
again.

Well, obviously if there is green under the white then the green was
never completely removed. If the green dates from the era I think it
does then there are probably 3-4 coats of oil paint on there and they
are failing. The only real solution is to remove ALL the old paint. A
paint job is only as good as the worst coat of paint under it.

Thanks a lot for the information.

I think the primer may have been put on when the wood was still wet from the
power washing. Also, one really bad area is where they ran a sprinkler and
the area was constantly wet.
