A new topcoat peeling from sound older paint calls for investigation of recent preparation, contamination, compatibility, and application conditions.
Remove all loose, lifting, bubbling, and poorly adhered paint.
Field practiceFor the older, peeling coating condition in the original pilot, I particularly favor an oil-based exterior wood primer.
Look for stains, checking, peeling, and physical damage. Identify dirt, debris, or contamination that must be removed. Material between the surface and the next coating can interfere with adhesion and contribute to later peeling.
Remove all loose paint, including adjacent areas that have detached but have not yet fallen away.
Once the surface is clean and dry, remove peeling paint and other loose coating back to firmly attached material.
Is the surface Level 5 smooth, knockdown, orange peel, or skip trowel? Note the heaviness of the texture. This first question guides roller selection and how closely application texture will show in the finished work.
I first look for rust, oxidation, and peeling paint.
On previously coated aluminum, also look for peeling, checking, bubbling, and other paint failure.
