Peeling paint is almost always a symptom of something underneath. Fix the cause first — or it'll peel right back in the same spot. Here are the usual culprits.
The most common causes
- Moisture: the number-one cause. A leak, condensation or damp behind the wall lifts paint from the surface.
- Poor prep: painting over dust, grease or a glossy surface without cleaning and sanding means nothing bonds.
- No primer: bare or patched surfaces need primer, or the topcoat has nothing to grip.
- Latex over old oil paint: a classic in older BC homes — water-based paint won't stick to oil without prep.
- Sun and age: years of UV and weather eventually break down even a good exterior finish.
How to fix it properly
- Find and fix the moisture source first — painting over damp guarantees it comes back.
- Scrape away all loose and flaking paint.
- Sand the edges smooth so repairs blend in.
- Prime the bare spots with the right primer.
- Repaint with quality paint in full, even coats.
