Render Crack

"A fissure in an external render, ranging from fine hairline crazing to structural cracks. Causes include thermal movement, substrate flex, and poor application."

In detail

Hairline cracks (<0.3mm) can be bridged by high-build masonry paint. Cracks over 1mm require cutting out, reinforcing mesh, and fresh base coat before redecoration. Always establish the cause before cosmetic repair.
