Peeling and poor adhesion
A finish can only hold to a stable surface.
Dust, grease, glossy coatings, moisture and loose previous paint can prevent adhesion. Preparation should address the condition rather than covering the symptom.
- Remove unstable material safely
- Clean and prepare for the selected coating
- Resolve active moisture before repainting
Flashing and uneven sheen
Patches and touch-ups can reflect light differently.
Porous repairs, inconsistent priming, uneven film build and viewing light can create visible dull or shiny areas. The correction depends on the surface and finish.
- Prime repairs where the system requires it
- Maintain a consistent wet edge
- Review walls under normal room lighting
Coverage and colour change
A dramatic change needs a plan, not just more paint.
Existing colour, coating quality, application and surface porosity affect coverage. Confirm colour, sheen and expected coat system before the room is disrupted.
- Use sample areas for important colours
- Discuss primer and coat expectations
- Separate colour approval from workmanship review
