If your kitchen cabinets are solid but the color is stuck in 1998, refinishing them is one of the highest-return updates you can make. The two main routes are brushed or rolled cabinet paint and sprayed lacquer, and they produce noticeably different results.
Cabinet paint, when it's a quality alkyd or urethane enamel applied with proper prep, gives a durable, attractive finish. Applied by brush and roller, though, it leaves some texture, and it cures slowly, so doors stay soft for days and can show fingerprints and dings during that window.
Lacquer is sprayed, dries in minutes, and builds up in thin coats that can be sanded between applications. The result is a glass-smooth, furniture-grade surface with no brush marks, and it hardens quickly enough that doors can go back on far sooner. It's the finish you see on factory cabinets, and done well, it's hard to tell refinished doors from new ones.
The trade-off is that lacquer requires real equipment, ventilation, and a controlled process: doors and drawer fronts come off, everything is degreased and sanded to a uniform profile, primed, and sprayed in a clean environment. It's not a weekend DIY project. But if you want your cabinets to look like they came that way, and to stay that way, lacquer is usually the right answer.
