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.
New paint cannot restore the bond of a detached old layer.
Check existing paint for adhesion and chalking.
If inspection finds peeling, loss of adhesion, water damage, or another failing condition, address that problem before applying these corrective coats.
