Render / Stucco

Render / Stucco covers exterior cement-based finishes that protect walls and make them look good for years.

I write about substrate prep, lath and base coats, mixing, application techniques, control joints, curing, waterproofing details, and patch repairs. You’ll also see guides on diagnosing problems like cracking, hollow spots, moisture damage, and delamination.
