Painting old plaster walls in Montreal
Older plaster walls have character, but they need careful reading before paint.
Understand the substrate
Plaster may have fine cracks, old repairs, powdery areas, or multiple paint layers. Each issue needs a different preparation method.
Painting too quickly can reveal defects or reduce adhesion.
Adapted preparation
The method may include local scraping, patching, gentle sanding, dust removal, and sealing primer. The goal is to stabilize the surface without erasing its character.
In Montreal homes and plexes, corners, high ceilings, and trim also need special attention.
Finish choice
A finish that is too glossy can reveal plaster waves. A quality matte or velvet finish often creates a calmer, more elegant result.
