How To Stop Peeling Paint



Peeling paint normally occurs when an exterior substrate is damp or wet for a long length of time.  When the surface is warmed by the heat of the sun, the water tries to evaporate by coming through the paint surface, which cracks the paint.  It is then just a matter of time before the paint starts to peel.  In order to fix this problem, follow these steps.


Materials Needed


Wire brush scraper, Peel Stop primer, TSP or other cleaner, sandpaper 




  1. Remove as much of the peeling paint as possible by scraping or using a wire brush.
  2. Thoroughly clean the surface to remove dirt, oil, grease, and other material that may interfere with adhesion.  Wash the surface with a strong detergent, such as ammonia and water.  Then Rinse the surface.
  3. Sand the edges of the remaining paint to create a smooth surface.
  4. Use a primer/sealer called Peel Stop manufactured by Zinsser.  Apply when the air temperature is between 50 and 90 degrees.  Apply by brush, roll or sprayer.  Back brush or roll to work the products into the cracks of the old paint. 
  5. If the peel stop dries to a dull sheen, apply a second coat.
  6. After the surface has been sealed, prime the entire surface with a primer such as 1-2-3 before applying your finish coat.


 Another Tip


Replace all of the caulking on the area that you are working on.  Caulk will shrink over time and can lead to rain and moisture getting into places where it shouldn't be.  If you do not replace the caulk, the priming and painting you did will not last for very long.
