Hi all. I am working on a paint job with some drywall repairs and repainting. Pretty simple. Yesterday I go to second coat the walls after priming and first coating and the entire wall breaks out in these crazy blisters!! You can push on the blisters but they come back. Then they peel.....in sheets. The client insisted on using Behr paint and I complied but after calling their customer service number I still have no clue how to fix the situation. The drywall mud had at least five days to dry and the first coat dried for at least a day. Any ideas how to fix it?
