Why is my paint peeling or cracking?
Peeling or cracking paint is almost always a sign of a problem underneath, not a paint-quality issue on its own — damp getting into the wall, poor preparation before the last paint job, or paint applied over a surface it doesn't bond to. Repainting over the problem without fixing the cause is why it keeps coming back.
If the peeling is near a window, roof line, or external wall, check for damp ingress first — a leak or failed render is a job for a roofer or general builder, not more paint.
New plaster needs a mist coat before a full coat of emulsion, and old gloss woodwork needs sanding and priming — paint applied straight onto either without that step will eventually fail.
In older properties, flaking paint on woodwork is also worth a cautious look before sanding — older coatings can contain lead, and disturbing them needs care.
What to check
- Is it near a window, roofline, or external wall (points to damp)
- Is it on new plaster (needs a mist coat) or old gloss woodwork (needs sanding/priming)
- How old the property is, if lead paint on older woodwork might be a factor
When to call a pro
If damp is the likely cause, sort that first — see our roofing and plumbing guides — then repaint.
