I have a problem with peeling paint on a 1920 house in Nashville, Tenn.
The house was gutted and remodeled 2 years ago. the wall construction is 2×4 studs, 5/8 drywall, no vapor barrier, 1/2 x 6 beveled spruce siding applied directly to the studs- no sheathing, no building paper, no housewrap. The stud cavities are filled with open cell foam applied directly to the siding. The paint job was poorly done with reports of the paint being applied without primer over siding that had been previously stained(age and condition unknown),and also reports of drywall mud being used to patch and skimcoat areas. The paint is lifting off the siding in bubbles the size of your hand. The failure is occuring on all areas of the house, both wet and dry, more so in the wet areas. The paint fails in the same way each time. First it turns loose in a 1 inch strip directly below the lap of the siding, the loose area then growing to cover the whole 5″ face of the siding. I opened a 2 sf area of a bedroom wall directly behind an area that was begining to fail (including foam) and discovered that the 1′ strip below the lap was very wet, the rest of the siding was only slightly wet if at all. The house was bought in late Sept. 09 and the paint job looked great. Following a 2 week occupancy at Thanksgiving the problems began and after a 2 week occupancy a Christmas the problems really accelerated. When the house was not occupied the heat was on with the thermostat set in the 50 to 60 range. My question- Is this only the result of a poor paint job or is the open cell foam applied to the siding part of the problem. Thanks, Tom
