You've seen the TikToks. A person with a foam roller and a gallon of "Cabinet Magic" transforms a 1990s oak kitchen into a sleek, emerald green masterpiece in a 15-second montage. It looks effortless. It looks cheap. It looks like something you can knock out on a Saturday morning before lunch.
Honestly? Those videos are lies.
Painting cabinets is a brutal, tedious, and technically demanding chore that most homeowners underestimate. If you jump in without a plan, you’ll end up with sticky doors that peel within six months and a texture that feels like orange peel. Most people fail because they treat a cabinet like a wall. It isn't a wall. It's a high-touch furniture surface that takes a beating every single day. If you want a factory-grade finish, you have to stop thinking like a painter and start thinking like a finisher.
The Prep Work Nightmare (That You Can’t Skip)
Let’s talk about grease. Even if you think your kitchen is clean, it isn’t. Years of bacon fat, steam, and skin oils have bonded to those door frames. If you paint over that, the paint literally won't stick. It’ll bead up or, worse, look fine for a week before sliding off in sheets. You need a heavy-duty degreaser like TSP (Trisodium Phosphate) or a substitute like Krud Kutter. Scrub until the water stops turning gray.
Then comes the sanding.
You don't need to strip the wood down to its soul, but you do need to "scuff" it. Use 120-grit or 150-grit sandpaper. You're just looking to break the shine of the old varnish so the primer has something to bite into. Many "no-sand" primers claim they don't need this step. Don't believe them. A quick scuff is the cheapest insurance policy you'll ever buy.
Label everything. Seriously. Put a piece of painter's tape inside the hinge hole of the door and write a number. Put a matching number on the cabinet frame. You think you’ll remember where the door for the "weird corner cabinet" goes? You won't. When you have 24 identical-looking shaker doors leaning against your garage wall, you will enter a world of pain trying to solve that jigsaw puzzle later.

Why Your Choice of Primer Is More Important Than the Paint
People walk into big-box stores and buy the most expensive "Cabinet Paint" they can find, then slap it over a cheap water-based primer. Huge mistake.
When you're painting cabinets, specifically if they are oak or cherry, you're dealing with tannins. These are natural oils in the wood that will bleed through water-based paint, leaving ugly yellow or brown streaks. You’ll keep painting over them, and they’ll keep appearing. It’s like a ghost in the machine.
The solution is shellac-based primer, specifically something like Zinsser BIN. It smells like a chemistry lab explosion and dries in about fifteen minutes. It is the only thing that reliably blocks those tannins and bonds to old, stubborn finishes. It’s thin. It drips everywhere. It’s a total pain to work with. But it works. If you use a standard hardware store primer on old oak cabinets, you are basically wasting your weekend.
The Grain Problem and Wood Fillers
If you have oak cabinets, you have deep, cavernous grain. If you just paint over them, you’ll see every single one of those "veins" through the finish. Some people like that "painted wood" look. Most people hate it.
To get that smooth-as-glass look, you have to use a grain filler. Aqua Coat is a popular choice among professionals. You wipe it on, let it dry, and sand it back. It fills those microscopic valleys so the paint sits flat. It adds a full day to the project. Is it worth it? Only if you can't stand the sight of wood texture.
Also, check your hinges. If you’re switching from old-school exposed hinges to modern "hidden" European hinges, you’re going to have holes to fill. Use a high-quality wood filler, not spackle. Spackle shrinks. Spackle cracks. Wood filler stays put.

Sprayer vs. Brush: The Great Debate
Everyone wants to use a sprayer. The finish is undeniably better—no brush marks, no roller stipple, just a smooth, misty coating. But the learning curve is steep. If you’ve never used an HVLP (High Volume Low Pressure) or an airless sprayer, your kitchen cabinets are not the place to learn. You will get "runs." You will get "sags." You will accidentally paint your refrigerator.
If you go the DIY route with a brush and roller, use a "mini-flock" or a high-density foam roller.
Apply thin coats.
Two thin coats are infinitely better than one thick, gloopy coat. Thick paint takes forever to cure, meaning it will stay soft and "tacky" for weeks. You’ll go to close a drawer and the paint will literally fuse together. This is called "blocking," and it’s the hallmark of a bad DIY job.
The Paint You Actually Need
Forget "Latex." Never use standard wall paint on cabinets. It’s too soft. You need what’s called an "Alkyd-Urethane Enamel" or a "Waterborne Alkyd." Brands like Benjamin Moore (Advance) or Sherwin-Williams (Emerald Urethane Trim Enamel) are the gold standards here.
These paints behave like oil-based paints—meaning they "level out" and hide brush marks—but they clean up with water. The trade-off? They have long "re-coat" times. Sometimes you have to wait 16 hours between coats. If you try to rush it and paint the second coat after only four hours, the bottom layer won't cure properly, and you’ll have a sticky mess that stays soft for months.

Setting Up Your "Drying Station"
This is where most people's houses become unlivable. You need a dedicated space to lay out 20+ doors. You can buy "Painter’s Pyramids" to prop them up, or you can build a rack out of 2x4s.
Keep the environment clean. A single dog hair or a speck of dust floating through the air will look like a boulder on a freshly painted white cabinet door. If you’re painting in a garage, damp down the floor with a little water first to keep the dust from kicking up when you walk.
The Curing Phase: The Hardest Part
This is the tip for painting cabinets that nobody wants to hear: Once you finish the last coat, you shouldn't put the doors back on for at least three to four days. And even then, you have to be incredibly gentle.
Paint "dries" quickly, but it "cures" slowly.
Drying is just the water evaporating. Curing is the chemical process where the paint molecules link together to form a hard, durable shell. This can take up to 30 days. If you put your bumpers on or screw the handles in too tight the day after painting, you will ruin the finish. Treat them like fine china for the first month. No scrubbing. No harsh chemicals. Just air.
Common Pitfalls to Avoid
- Ignoring the Backs: Always paint the backs of the doors first. If you get a drip on the edge, it’ll be on the front of the door where it’s less visible, and you can sand it off before you flip them to do the "show side."
- Cheap Brushes: A $20 brush is cheaper than a $2,000 professional paint job. Buy a Purdy or a Wooster. The bristles don't fall out as easily, and they hold more paint, which leads to fewer strokes and less texture.
- Climate Issues: Don't paint in the garage if it's 90% humidity or 40 degrees Fahrenheit. The paint won't dry right. Aim for a goldilocks zone of 60-75 degrees.
- Skipping the Micro-Sand: Between every single coat of primer and paint, hit the surface lightly with a 220-grit sanding sponge. It knocks down any "nibs" or dust particles. Wipe it clean with a tack cloth afterward. It makes the final result feel silky.
Actionable Next Steps for Your Project
If you are ready to tackle this, don't start by ripping the doors off. Start by testing.
- Buy a Sample: Get a small quart of the primer and the specific paint you want.
- The Test Door: Find a door in a laundry room or a bathroom—somewhere low stakes—and go through the entire process. Degrease, sand, prime, sand, paint, sand, paint.
- The Scratch Test: Wait three days, then try to mar the finish with your fingernail. If it peels or scratches easily, your prep wasn't good enough or your primer is wrong.
- Inventory Your Hardware: If your hinges are old and greasy, buy new ones. Putting old, gunked-up hardware back onto fresh paint is like wearing dirty shoes with a tuxedo.
- Schedule the "Void": Realize that your kitchen will be a construction zone for at least 7 to 10 days. Plan for takeout or slow-cooker meals in another room.
Painting cabinets correctly is about 80% preparation and 20% actually moving a brush. It is a test of patience more than it is a test of artistic skill. If you follow the "Clean, Scuff, Prime, Paint" mantra—and don't skip the shellac—you'll have a kitchen that looks like it cost $15,000 to remodel for the price of a few gallons of high-end enamel.
