Introduction Restoring plaster picture rails means repairing damaged plaster while keeping the thin, shadowed groove where the rail meets the wall intact. This is a hands-on patch job that focuses on feathering new material into the old, matching texture, and protecting the shadow line during work. Expect to use basic plastering tools, patching compounds, and […]

Introduction Plaster cornice repairs using simple running molds means making a flexible or straight guide that lets you press or cast matching profile runs to restore damaged cornice sections. It’s a hands‑on jig you shape to the original profile and use to form or press repair material in place. This approach is practical for small

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 Repairing plaster around window casings means removing loose material, backing up the returns, and filling and finishing so the casing meets the wall with straight returns and crisp corners. This is a hands‑on job that starts with good surface prep and the right tools—check product labels for compatibility and drying times before you buy.

Introduction Reinforcing plaster at material transitions means embedding the right type of mesh or alternative so the joint won’t crack or show through once the plaster dries. Pick a mesh compatible with your plaster and substrate and follow the product label and common-sense joint detailing to avoid telegraphing. If you’re unsure which mesh to use,

Introduction Plaster delamination “bubbles” are areas where the top plaster coat has lost adhesion to the substrate and forms a raised blister that can pop or tear back. This usually means moisture, weak bonding, or movement has separated layers; check the surface and product instructions to confirm causes before you act. In many cases you

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 Plaster over cement board means using the right bond coat and a keyed scratch surface so the plaster mechanically and chemically adheres to the board. In plain jobsite terms: use a compatible bonding agent or cement-based scratch coat, make a consistent scratch pattern so the plaster keys, and follow product label instructions for mixing

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
