We have a large (40 x 10) covered patio that is only one side open air, it has two ceiling fans up there, there is a 6″ wood edge along the top of the roof where the patio is open to the outside. There is a treatment on the ceiling that was applied with a sponge texture of some sort (stucco???) painted w/ latex and on the 3 sides closest to the open side there are now appearing blistering.
The paint/finish was applied in Dec which is the dry cool season here in Central Fl. It is now HOT & Humid and as that occurred the blistering occurred.
We need to correct and are looking for advice on how to prevent this from occurring in the future.

Perhaps there was no primer before the stucco was finish coated… it needed to be primed first with a Pigmented Shellac Sealer Primer… or an Oil Base Stain Killer…
Scrape it and sand it down with course grade paper and/or wire brush … then prime it (use Pigmented Shellac) then finish coat with a high grade product like Sherwin Williams A-100 (an exterior acrylic product, since it is exposed to the outside climate)… use a flat finish on the stucco…
