Paint adhesion is lost and the loose paint starts coming off in single to multiple coats.
PEELING PROBABLE CAUSES
Usually improper surface prep and not identifying the conditions that need pre-painting attention. Uncontrolled moisture conditions, painting over rust, loose paint, chalking paint or dusty surfaces.
MASONRY PEELING SOLUTIONS
Remove all the loose paint with a wire brush. Power washing or sand blasting is recommended for large areas. Fill all cracks with a masonry patching compound. Use an alkali-resistant primer.
METAL PEELING SOLUTIONS
Remove all the loose paint and rust. Apply a rust conversion or rust inhibitive primer. Lightly sand factory primed metal and remove dust.
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.
