Blistering Paint

Got a weird one for all of you. Trying to paint a bathroom using good quality paint, Porter. We are priming the walls first, with Porter primer. Once appliend, the paint started to blister. What would cause this? The guys are Porter didn't have a clue.

Thanks

Is the old paint oil base? Did you sand before priming? Was it a latex primer?

I did sand, the primer is latex and I from what I can tell it's not oil base paint (but could be wrong). If it is oil base, would I really see blistering? If so, what is the correction?

It can be difficult to get latex to adhere to interior oil base enamels. If you indeed did apply latex over oil, it is best to remove as much of the latex as possible and prime with oil base [or shellac] Sometimes aggressive sanding will be good enough for latex to adhere.

It is also possible some sort of contamiment was on the wall preventing the primer from adhering.

The primer is blistering?
Or the primer went up fine, and the paint is blistering?

If it's the primer, post up exactly what the label name says
Do the oil/latex test on the previous paint (the sticky is at the top of the paint forum) and post the results
And post up exactly what steps and/or products, if any, you used to prep the wall before applying anything
