Exterior wall cracks
3-year old block & stucco IVY. I'm seeing hairline stress cracks in the stucco exterior beneath most windows. Some cracks, while hairline width, run 3 feet or more. Have been filling in the cracks with touch-up paint.
1. Is filling in with paint the right thing to do (vs caulk and paint)?
2. Is this a precursor to a larger problem?
