Painting a room with BM satin paint and walls have blisters showing up under new paint job. Tempature at 70 degrees in house. Room was painted once before 5 years ago. Walls were spackled, dried and sanded. Any Ideas

Did you give enough dry time between coats? This will cause problems.
What type of paint was put on 5 years ago? You didn't put latex on oil?
Was it papered 5 years ago? Latex will activate any clue left behind creating blisters. Anybody have any other ideas??

Sounds like what you are calling spackle might have been joint compound that was sanded and painted over unprimed before it was dry? There is nothing that will blister paint like uncured joint compound.

I'm assuming j/c rather than spackle also...

Lack of primer and/or not dusting the joint compound repairs would do it
Neither was mentioned as part of the process

blisters are typically due to poor prep from previous paint jobs. Example - walls were plaster, previous painter painted them without primer - heck, the homeowners painted them without priming - I've seen this. Homeowners that start trying out spots of color all over their plaster walls without primer. Anyways, it will work the first time - but second or perhaps 3rd recoat over said base - will detach the poor bond and cause blisters.
