A new finish must adhere to the actual prepared surface it will touch.
My cleaning check is a fresh-rag wipe: no visible contamination should transfer. Repeat cleaning where residue remains. A visually clean surface still needs the adhesion and compatibility checks for the chosen system.
Field practiceWhere I use water-based grain filler, I prefer to apply it after a compatible bonding primer, such as STIX, because I have experienced beading over sanded lacquer.
The reviewed DTM Acrylic sheet lists a separate bonding-primer system for baked-on siding finishes. Its previously painted-surface guidance calls for an adhesion test after a one-week drying period.
Only after investigating other likely causes should widespread, gradual release at the original coating-to-wood bond be attributed to age-related failure.
If inspection finds peeling, loss of adhesion, water damage, or another failing condition, address that problem before applying these corrective coats.
