To make a long story short - I have an old house (asbestos/asphalt shingle siding). It has probably been painted many times. I lived in the house for 5 years with no blistering at all - my neighbor has not seen blistering for 10 years. Shortly after it was repainted last fall it started blistering (up to softball sizes!). Painter told me it would settle down after the summer heat cured it. No sir - back with a vengeance after any good rain. Anyhow, painter finally came and punctured a blister and water poured out. After peeling it back, it peeled right down to the siding. Painter says that because it goes down to the siding, this is not their fault, but is rather a breakdown in the prior primer/paintjobs. Obviously (to me) they at the very least triggered something to cause this. Could they have pressure washed too hard? Would not drying properly after washing potentially cause this? I should note that this house seems to have peeled in the past. The painter pointed out (after the fact) numerous spots where peeling appears to have occured in the past. However, nothing was wrong for years. They basically acknowledge that this house can never be properly painted again without stripping all the way down (they won't do this). Any ideas as to solutions and whethet this was their fault.

Get manufacturer’s representative to look at the problem. Do this yourself instead of having the painter do it. (Keep it unbiased) Find out what they say the problem is and go from there.
