Intercoat peeling

Back to exterior problems...
Occurs in protected or shady areas where condensation collects sulfur dioxide from air. These salt like crystals are washed away by rain in areas not protected. Painting over these crystals will cause peeling as the salt draws 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, shinny surface.

Intercoat peeling solutions - wash and rinse thoroughly before repainting. 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 and Exterior Finishes - Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Ask your Muralo dealer for the best Muralo exterior paint for your project, in the color and sheen of your choice.
