DESCRIPTION

Loss of adhesion of exterior paint, usually exposing the bare surface.

POSSIBLE CAUSE

Peeling results when a wet substrate (e.g. the surface that has been painted) swells, causing the paint film to loosen, crack, and fall off. Among the variety of ways for water to seep under the paint film are:

• Worn-out or no caulking in joints, corners, and openings, allowing moisture to enter.
• Interior moisture migrating through to the exterior walls.
  

• Painted surfaces that are too close to bare ground.
• Leaking roofs.
• Painting  a surface that is damp with rain, condensation, or dew.

SOLUTION

Remove loose or cracked caulking and repair with a quality product.

Install vents, louvers, fans, and dehumidifiers to reduce moisture, especially in the kitchen, bathroom, and laundry area.

If wood siding is touching the ground, remove that portion of the wood. Siding should be installed not less than 6" above the ground.

Repair the roof as needed.

Test the coating in a 6" to 12" radius around any peeled areas to be sure the adhesion is adequate.
