*** PEELING ON GUTTERS & DOWNSPOUTS
Peeling will eventually occur whenever something comes between the substrate and its coating. Applying paint over a layer of grease, detergent film, dirt, oil, wax or moisture is a common cause of peeling. Another is the failure to properly prime your substrate. Solutions vary according to the substrate being painted.
Solutions for Gutters and Downspouts: Sand to bare metal. Wipe down with a solution of 1 part vinegar and 4 parts water. Reprime Oil Base Primer Sealer and repaint House & Trim. Peeling of gutters and downspouts can almost always be avoided by applying primer prior to painting.
