Introduction Fixing plaster cracks at ceiling medallions means cutting relief gaps to stop old stresses and then rebuilding the substrate so the medallion sits on sound plaster, not cracked or loose bits. Start by exposing the damaged area cleanly, check the lath condition and how the medallion is attached, and decide whether to repair lath […]

Introduction Salts in masonry plaster are soluble minerals that migrate to the surface as moisture moves through the wall, leaving white or powdery deposits called efflorescence and in worse cases causing spalling where the plaster flakes or crumbles. This usually comes from water intrusion, damp soils, or moisture wicking through masonry and carries salts via

Introduction Plastering over painted masonry can be a challenge due to the existing paint layer. To ensure a strong bond and prevent peeling, decontamination is crucial. The process involves removing contaminants that could compromise adhesion. By following these steps, you’ll improve the bond between your new plaster and the painted surface. Key takeaways Assess feasibility

Introduction Veneer plaster repairs are the process of fixing damaged plaster by feathering new material into the old so the wall looks continuous and solid. This means assessing whether the existing veneer is well-bonded, cleaning and wetting the surface, and choosing a compatible patching mix and bonding method. I’ll focus on practical steps you can

Introduction Plaster key failure on wood lath happens when the plaster pulls away from or loses grip on the lath, leaving loose or hollow areas that will crack or fall out. This write-up shows practical ways to diagnose where keys failed, how to re-key small patches, and when adding mesh or repairing lath is the

Introduction Fixing rust bleed through plaster means stopping iron staining at the metal source and isolating it so stains don’t reappear through new finishes. In practice that means exposing the area, treating or replacing corroded metal, and using an appropriate isolation/stain-blocking primer before replastering or painting. Check product labels and manufacturer instructions for compatibility with

Introduction Plastering over old calcimine paint means confirming the paint is the flaky, powdery lime-based finish that repels new plaster and then removing or treating it so plaster can bond. I’ll show simple tests to identify calcimine and practical fixes for adhesion problems you can do with common tools. If a product or spec matters,

Introduction Getting dead-flat plaster walls means using straightedge checks and a stepwise build-up of layers until any high or low spots are leveled out. It’s a practical process of finding the worst deviations, feathering in material, and rechecking with a straightedge until the surface reads flat to the eye and tool. Expect to use joint
