Painting Kitchen Cabinets So the Finish Actually Lasts

Painting cabinets is one of the most dramatic upgrades you can make to a kitchen or bathroom without replacing anything. It's also one of the easiest paint jobs to get wrong. Cabinets are handled every day, splashed with grease and water, and bumped by pots and shoes. The paint has to stick hard, level smoothly and cure tough.

Why cabinet paint jobs fail

Nearly every failed cabinet job we see has one of these causes:

• Grease left on the surface. Kitchen cabinets near the stove carry invisible cooking oil; paint won't bond to it.
• No sanding or bonding primer over a slick factory finish or old varnish.
• Wall paint used instead of a cabinet enamel. Wall paint stays soft and sticks to itself, so doors stick to the boxes.
• Thick coats that sag and stay soft underneath.
• Rushing back into use before the paint has cured.

What kind of cabinets do you have?

Solid wood and wood veneer (oak, maple, cherry, birch) paint very well with proper prep. Oak has open grain that shows through paint as texture; you can keep it or fill it (see below). MDF doors paint beautifully but must be sealed carefully, especially on cut edges. Thermofoil and laminate are plastic-wrapped surfaces that are harder to paint; peeling or bubbling thermofoil can't be fixed with paint. Older painted cabinets may contain lead paint in homes built before 1978; see our lead-safe guide.

Choosing the products

Primer

Use a primer designed for bonding to glossy surfaces or for cabinets. On oak and other tannin-rich woods, a shellac-based or other stain-blocking primer stops tannins from bleeding through light colors as yellow or brown spots. On knots, spot-prime with shellac.

Topcoat

Choose a cabinet and trim enamel. Waterborne alkyd and urethane-modified acrylic enamels are popular because they level out smoothly like oil paint and cure hard, with easier cleanup and less yellowing than traditional oil. Traditional oil-based enamels are very hard and level beautifully but yellow over time, especially whites, and have strong odors.

Sheen

Satin and semi-gloss are the most common for cabinets. Semi-gloss is easier to wipe; satin hides small imperfections better. Matte cabinet enamels exist, but check that the product is rated for cabinets.

Spraying vs brushing and rolling

Spraying with an HVLP or airless sprayer with a fine-finish tip gives the smoothest, most factory-like finish. It requires removing doors, a clean spray area and masking everything else. Brushing and rolling with a quality synthetic brush and a fine foam or microfiber roller can look very good with self-leveling enamels, especially on flat doors. Many pros spray doors and drawer fronts off-site and brush and roll the boxes in place.

The cabinet painting process

1. Empty the cabinets, label every door and drawer with its location, and remove doors, drawers and hardware.
2. Degrease every surface with a dedicated degreasing cleaner, then rinse with clean water and let dry.
3. Repair dings and gouges with wood filler and fill unused hardware holes if you're changing pulls.
4. Scuff sand all surfaces with fine sandpaper or sanding sponges to dull the gloss, then vacuum and tack off the dust.
5. Mask walls, countertops, appliances and the cabinet interiors you aren't painting.
6. Prime every surface with a bonding or stain-blocking primer suited to your cabinets.
7. Lightly sand the dried primer smooth, then remove all dust.
8. Caulk small gaps where face frames meet walls and where panels meet frames, if needed.
9. Apply the first thin coat of enamel, starting with the back of doors, then let it dry fully.
10. Lightly sand between coats and apply the second coat to all faces.
11. Let the doors cure as long as you can before rehanging, then install bumpers and hardware.
12. Treat the finish gently for the next few weeks while it fully hardens.

Dealing with oak grain

Painted oak shows its grain as a pattern of small grooves. Some people like it; others want a smooth modern look. To minimize grain, apply a grain filler or a heavy-bodied primer, sand it smooth and repeat as needed before the topcoat. This adds real time to the job, so decide up front.

Curing: the step everyone rushes

Most cabinet enamels are dry to the touch in hours, but they take days or weeks to reach full hardness, depending on the product, temperature and humidity. During that time the finish is easy to scratch and can stick to bumpers or other doors. Install soft bumpers, open and close doors carefully, and avoid harsh cleaners for the first few weeks.

How to care for painted cabinets

Clean with a soft cloth and mild soap. Avoid abrasive sponges and strong solvent cleaners. Keep leftover paint for touch-ups; small chips are easy to fix if you deal with them early.

DIY or professional?

A kitchen cabinet painting project is a big commitment: it typically takes many days for a DIYer and the kitchen is out of commission during prep and painting. Professionals bring spray equipment, controlled conditions for doors and experience with the products. Either way, the steps above are the ones that matter.
