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.
I believe it was a Glidden latex (I'm not 100% sure of the latex though - I know it was Glidden). The length of time that they waited to paint the house after washing is an issue. My wife says they painted the same day. The painters say they waited until the next day. I'm wondering if they should have waited even longer than one day for this type of asbestos shingle siding. Do you have any thoughts. Thanks for your reply.
I feel that even 1 day is not long enough to wait afetr power washing a house it should be at least 3 clear days before painting is started. There may have been some paint that was loose on your house that did not show up while they were working on your house and latex paints shrink when they dry and that will pull off any paint that is not adhearing to the surface.If it is just a few spots you should be able to touch up thoes areas. Also bear in mind that once a house hits a certain age the original paint is going to let go and take all of the later coats with it and the only way to stop this from happening is to remove all the paint and start over. Hope this helps out.
