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.
Manufacturer directionCabot distinguishes penetrating finishes from film-forming coatings: solid stains can peel, and excess penetrating stain can form a surface film that also fails.
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.
Look closely for peeling, bubbling, and fine cracking or checking.
Surface condition: Peeling, bubbling, or checking · My field sequence: Remove the failed material; start around 120 grit, feather with 180 or 220, and finish with 320.
Allow the specified evaluation time and check for lifting, softening, beading, poor adhesion, and an unacceptable finished appearance.
Neither a conditioner nor a primer turns loose paint or unstable stucco into a reliable substrate.
For light sand-finish stucco, comparable in texture to orange peel, I typically use a 1/2-3/4-inch nap.
I first look for rust, oxidation, and peeling paint.
On previously coated aluminum, also look for peeling, checking, bubbling, and other paint failure.
If inspection finds peeling, loss of adhesion, water damage, or another failing condition, address that problem before applying these corrective coats.
Drywall finish: Light orange peel · My nap length: 3/8-1/2 inch · Cover choice: Microfiber, lamb's wool, or synthetic fiber compatible with the coating
