Steps

Goal: Map which paint layer fails and whether moisture or chemistry caused it.

  • Tape-test; note if bare drywall, primer, or old oil is exposed.
  • Good: Localized—feather wide and use correct primer.
  • Bad: Chalky substrate everywhere—consider full strip or pro spray.

Interior

Goal: Match primer to slick or stained surfaces in baths and kitchens.

  • Use mold-killing primer only where needed; do not substitute for leak repair.
  • Good: Topcoat adheres after 24-hour tape test in inconspicuous spot.

When to get help

Hire a lead-certified contractor for:

  • Disturbing more than small areas of probable lead paint.
  • Multi-story exterior where ladder work is unsafe for you.

Verification

  • No lifting edges after light fingernail scrape at seams.
  • Color and sheen match surrounding area at eye level.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Tape test See which layer fails.
  2. Scrape sand Feather edges.
  3. Prime coat Right primer for substrate.
  4. Pro Lead or spray cabinets.

Frequently asked questions

Why does bathroom paint peel?
Steam-softened paint, wrong sheen for wet walls, or latex applied over glossy oil without primer.
Can I paint over peeling paint?
No—remove loose material first or new paint will release with the old layer.
Do I need oil primer everywhere?
Use oil or shellac primer on tannin knots, stains, and slick surfaces; PVA on new drywall only.
