Blisters in Acrylic Stucco Texture

user-6833488 | Posted in General Questions on

We have an issue with acrylic stucco texture coat blistering off of the brown coat. Stucco system is

1-ply of 60 min Fortifiber paper over 1-ply of Fortifiber Henry WeatherSmart Housewrap, with

1″ Rigid R-Tec, Platinum Foam, then 1/2″ brown coat then the Acrylic texture coat and painted with Dunn Edwards Spartasheild acrylic flat paint.

Seems to come a go.  Comes during this time of year as the sun gets a bit hotter on the wall.  Blisters reduce/retract during cooler temps.  We are in N. California Climate Zone 4B.

Any ideas what is going on here?
