Under Eaves Peeling
Intercoat peeling: Occurs in protected or shady areas where condensation collects sulfur dioxide from air. These salt crystals are washed away by rain in areas not protected. Painting over these crystals will cause peeling as the salts draw moisture through the paint.
Peeling probable causes: Improper surface preparation to painted surfaces located in areas protected from weather. Condensation causing a collection of salt crystals from the air. If salt deposits aren’t removed, new paint will peel. Lack of adhesion of a top coat over a hard, shiny surface.
Intercoat peeling solutions: Wash and rinse thoroughly before painting. When dry, remove all loose paint with a scraper or wire brush. Sand all glossy areas and remove sanding dust. Remove mildew if present. Mix 1 part bleach with 3 parts water.
Primers & exterior finishes: Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality exterior paint in your color and sheen.
