How To Fix Flaking, Cracking or Peeling Paint
Simply painting over any cracked, flaky or peeling paint will not resolve the issue, in fact it will cause it to become a bigger problem. Issues will arise from the new paint not adhering to the surface unless you have removed the flaking peeling paint and prepped the surface properly. It is important that the old flaking paint is scraped off first before painting over the area.
If you are the DIY type painter, here are a few tips you can follow to ensure you repair the problem properly, and prevent it from happening again.
- Never apply oil based paints over a latex based paint
- Apply minimum of two coats of paint over a properly primed surface.
- Use high quality paints that provide good coverage and prevent you from having to paint often
- Allow enough time in between coats of interior or exterior paint to dry completely. Failure to allow sufficient drying time in between the application of paint coats will cause poor adhesion, followed by paint problems such as peeling, cracking, flaking, sticking or blistering bubbles.
- Remove the loosened or flaking paint with a scraper for interior paint or wire brush exterior paint.
- Sand the area to smooth everything out. Patch any drywall compound to create a smooth surface on any interior walls or ceilings and use a filler if necessary after scraping off several layers of old paint.
- Use a good paint primer to ensure the best protection to the surface and the best adhesion of your final paint finish.
