Cabinet refinishing, explained

A durable cabinet finish is mostly prep: degrease, scuff-sand every glossy surface (220 grit or coarser), apply a bonding primer matched to the substrate, then spray two or more thin coats, sanding lightly between them.

Dry isn't cured. One cabinet enamel at 77°F and 50% RH is dry to the touch in 4–6 hours and recoatable in 16, handles light use after 5–7 days, and can take up to 30 days to reach full hardness. Cool or humid conditions slow every step.

Cabinet enamels level out to a hard, furniture-like finish, and catalyzed conversion varnish meets KCMA tests for chemical, moisture and mar resistance. Catalyzed finishes have a limited pot life and some need at least 70°F to cure (varies by product).
