Introduction Delamination in stucco paint means the coating is no longer firmly attached to the underlying surface. Testing adhesion before repainting shows whether the surface is ready to be prepped and primed. A quick check helps you plan the cleaning, scraping, and sealing steps. To test adhesion, use a simple peel or lift test on […]

Introduction Cracks at stucco corners are stress-related failures at the joints where surfaces meet. They form when the wall moves or settles and the outer layer can’t flex enough. Addressing them starts with understanding where the stress concentrates and how the mesh supports the patch. Repair technique should reinforce corners with proper mesh at joints

Introduction Bottom-edge stucco moisture wicking occurs when capillary rise pulls moisture from the foundation into the lower stucco courses. This guide helps you spot the signs and understand why the drainage plane matters. Look for damp patches, staining, softening, or peeling where the stucco meets the foundation, and check for poor drainage or blocked weep

Introduction Tracking hidden metal in stucco is the process of locating metal components behind the stucco to prevent rust-related damage. Rust stains can reappear if metal isn’t found and treated. This introduction covers practical steps for checking, repairing, and preventing future issues. Techniques for detecting hidden metal include visual clues and non-destructive checks. Common causes

Introduction Stucco patches can blend in by matching the sand texture, applying a light fog coat, and feathering the edges to disappear. This approach focuses on how the repair looks from close up and at a distance, not on replacing the entire wall. It’s a practical, hands-on method for making repairs less noticeable. Start by

Introduction Screed straightening of the stucco brown coat is the process of leveling and smoothing the outer layer to prevent visible waves. It relies on controlled, even passes with a straightedge to create a flat, true surface. The goal is to set the first and second coats with minimal movement after initial setting, while maintaining

Introduction Keying the scratch coat means creating a rough, gripping surface on the lath so the plaster adheres without excessive manipulation. It gives the base a bite that helps the next layer hold. Start with thorough surface preparation: clean and dampen the lath so dust is removed and the surface isn’t drawing moisture too quickly.
