Peeling - Due to Moisture (Outside)

Loss of adhesion of exterior paint, usually exposing the bare surface.
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.
  • Ice-filled or clogged gutters, causing moisture build-up under the shingles.
  • 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.
Remove loose or cracked caulking and repair with a quality product.

Clean and repair gutters so they properly channel water away from the house.

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.

Follow label and data page directions for proper surface preparation and environmental conditions.
