Paint and acrylic caulk are blistering 3–4 months after renovation work.
Hi!
Walls are replastered clay brick walls, quality products were used, and there’s acrylic caulk between door frames and walls.
The house was not heated during winter due to ongoing renovations, and the issue appeared recently after warmer weather. Mostly above doors and on corners.
The plaster underneath does not seem damp or crumbly.
Could this simply be caused by humidity/temperature changes and the walls still stabilizing?
