We had to do some repairs to some walls, putting up a few sheets of new
drywall. We used Durabond setting type drywall compound, both all-purpose
and then lightweight. We used Conco PVA primer/sealer and Pittsburg latex
paint sprayed on with an airless painter. A few hours after painting we
went back and found several spots where the setting type lightweight
compound turned soft and bubbling up, but only over the old, smoke-covered
walls, not over any of the fresh drywall. We also found a spot where no
work had been done, but it is bubbling up too. We have more painting to do
and don't want the same problems. Any ideas on what happened and how to
prevent it? Thanks.
