Paint adhesion is lost and the loose paint starts coming off in single to multiple coats.
PEELING PROBABLE CAUSES
Moisture trying to escape through the paint film. This is more common with oil-based paints. Moisture leaks from roofs, walls, uncaulked or dried-out caulked joints. Painting over a wet surface with alkyd or oil-based paint. Inadequate surface preparation.
Identify and eliminate the cause of moisture. Long term satisfaction is assured when moisture is controlled. Remove all loose paint by scraping. Power washing is recommended for large areas. Feather sand edges for smooth appearance and rinse thoroughly with a hose.
PRIMERS & EXTERIOR FINISHES
Spot prime all bare areas for better adhesion, sheen uniformity, mildew control and durability. Select a top quality exterior paint in the color and sheen of your choice.
