TL;DR
An adhesion test is a field check of how firmly an existing coating grips its substrate, performed before repainting by cutting a small crosshatch or X through the film and pulling firmly bonded tape across it, per ASTM D3359. If flakes lift on the tape, the old paint must be scraped, sanded, or primed with a bonding primer before topcoating, because new paint can only hold as well as what is under it.
What it means
An adhesion test is a field check of how firmly an existing coating grips its substrate, performed before repainting by cutting a small crosshatch or X through the film and pulling firmly bonded tape across it, per ASTM D3359. If flakes lift on the tape, the old paint must be scraped, sanded, or primed with a bonding primer before topcoating, because new paint can only hold as well as what is under it. Painters run it on chalky siding, glossy trim, and previously peeling areas. The few minutes it takes can prevent a whole-house peel failure a year later.
