All good points. The painters did consider moisture, but didn't think moisture was involved. I was concerned about the Laura Ashley paint, but took comfort in the fact that it was manufactured by Valspar (out of Wheeling, IL) which produces some other good paints. I called the Valspar Customer Service Hotline, and found them to be very professional. They asked us to send some of the paint flakes for analysis, and said they would then be able to recommend a solution. I will keep you posted on what they discover.
