Hi,
Most of the bubbling is occuring was previously painted with semi-
gloss Moorgard paint- It was an acrylic paint.
Before the painting they were supposed to prime it and do two layers
of new semi gloss Benjamin Moore paint. Sounds to me from all the
feedback that he might have missed the priming step or not allowed the
primer to completely dry before adding the other coats on.
As for the initial powerwash, how long do painters usually wait?
Thanks for your feedback.

Can you determine what primer was used? My suspicion is that it was an
oil base over a still damp surface possibly followed too soon with a
waterbased top coat.

What kind of response do you expect from the painter, I bet it will be
along the line of, "I dont know it must be defective paint I did
everything right". Some of the areas look like water could now be
entering from behind, cut open bubbles to see if any water is in them
indicating it could be your issue. Did he paint over gloss oil, did he
paint in sun or a sun heated surface. Ben Moore has local reps that
might come over, they do have a lab you can ship a piece of wood with
bubbling paint to, that will be conclusive as to reason of failure. I
painted for years and cant remember that happening, it might be
several things that happened like wet wood and sun, wet as in wet from
old leaks and pressure washing, but bubbled areas never bonded.

*Take your pictures over to the paint store where you got the paint and see
what they say.
My thoughts are that one day was not enough for the house to dry after
power washing. Also could be a compatibility problem with the old paint.
You didn't say if primer was used or not, but I am wondering if a second
coat of paint was applied before the first coat or primer fully cured.
It remains to be seen if this will continue or not. The problem may
eventually stop, but I wonder if the bubble areas will ever adhere properly
and last as long as the rest of the house.

Maybe wrong type of paint (acrylic?) applied either over a still damp
surface or a house that has moisture within its walls.
Here in a much cooler climate it is wisest to use some sort of stain.
Not paint that forms an impermeable skin that does not allow moisture
(water) to breathe/evaporate to outside. And the amount of moisture
also depends on the interior of the house having a proper moisture
barrier. But not familiar with your conditions.
