The paint looked perfect for about four months. Then it started chipping everywhere a fingernail lands: the edge beside the sink, the rail under the handle, the corner a knuckle catches when a door swings back too hard.
That failure is almost never the paint. Cabinets chip because the paint had to grip grease, a factory gloss, and a bare surface no primer ever keyed into. Fix those three, and a repaint on a sound box holds for years.
The steps below cover that, plus an honest read on when new doors cost less.
TL;DR
Adhesion is the whole game. Degrease, scuff the gloss, and prime with a bonding primer before any color goes on.
- ●Two or three thin coats of a cabinet-grade enamel beat one thick coat every time, and each coat needs real dry time.
- ●Paint fully cures over two to three weeks, so cabinets feel dry long before they are hard enough for daily abuse.
- ●Thermofoil, melamine, and swollen fibreboard doors do not take paint reliably. On those, new doors are the better call.
- ●A careful DIY repaint runs a few hundred dollars in materials. New factory-finished doors or full cabinets are a bigger number but reset the boxes, the hinges, and the finish at once.
Why Painted Cabinets Chip, and What Actually Prevents It
Every early paint failure I see traces back to the same short list. Learn it once, and you can inspect your own work as you go.
| The cause | Why the paint lets go |
|---|---|
| Grease | Kitchen cabinet doors carry a thin film of cooking oil and hand oil that a quick wipe does not remove. Paint over it and the paint bonds to the grease, so the grease is the weak layer. |
| Gloss | Factory finishes are cured hard and slick on purpose. A fresh coat slides off a glossy surface unless you dull it first. |
| No primer | Color paint is formulated to look good and flow. Gripping a foreign surface is the primer’s job, and a bonding primer is the glue coat between the old finish and the new one. |
| One thick coat | Heavy paint sags, traps solvent, and stays soft underneath for weeks. Thin coats dry through and stack into a harder film. |
| Rushed cure | A door can feel dry in an hour and still dent under a thumbnail for two more weeks. Reassemble too soon, and the first knock leaves a mark. |
Get those five right and the finish stops peeling at the handles. Miss any one and the kitchen tells on you by month four.
What You Need Before You Open a Can of Paint
Buy the materials for the job, then set up so you can prep, prime, and paint without stopping to hunt for a tool. Here is the working kit.
- ●A grease-cutting cleaner. A strong degreaser or a phosphate-free TSP substitute lifts the cooking film. Rinse afterward so no cleaner residue stays on the surface.
- ●Sandpaper or a liquid deglosser. Medium grit around 120 to 150 for scuffing, and a finer 220 grit for knocking down each primer and paint coat.
- ●A bonding or stain-blocking primer. That coat decides whether the job lasts.
- ●A cabinet-grade enamel. Water-based acrylic and urethane trim enamels made for cabinets and trim level out smooth and cure hard. In Canada, they are also formulated to meet the country’s paint emission rules, which I cover below.
- ●A quality angled brush and a smooth foam or microfibre roller. The brush cuts the grooves and profiles; the roller lays the flats.
- ●Painter’s tape, a screwdriver or drill, sandwich bags for hardware, and a labeling system.
- ●A dust mask and ventilation, which matter more than most guides admit once you start sanding.
Buy the best enamel your budget allows. The paint is the cheapest part of the labor you are about to put in.
How to Paint Kitchen Cabinets Step by Step
Work in order. Each step exists to protect the one after it, and skipping the boring middle steps is exactly how a finish fails early.
Which Cabinet Surfaces Do Not Take Paint Well
Not every door is a candidate. Before you buy a single can, find out what your doors are made of, because two common surfaces fight paint no matter how well you prep.
- ●Thermofoil. A vinyl film is heat-wrapped over a fibreboard core. Paint struggles to bond to the vinyl, and once thermofoil starts lifting at a seam, it cannot be repaired, only replaced. The same trait that makes it hard to repaint is covered in our breakdown of painted doors versus thermofoil.
- ●Melamine and high-pressure laminate. These are hard plastic surfaces fused to a substrate. A specialty bonding primer can grip them, but the failure rate on a busy kitchen is high, and the result rarely looks factory.
- ●Swollen or water-damaged fibreboard. Once a particleboard or MDF door has absorbed water and swelled at the bottom edge, paint hides nothing, and the panel keeps failing underneath. Paint is a finish and cannot rebuild a failed panel.
Solid wood and factory-painted wood or fibreboard doors that are still flat and sound are the reliable candidates. If yours are thermofoil or swollen, skip ahead to the paint-or-replace section, because a repaint on those is money spent twice.
Paint Safety Worth Knowing in a Canadian Kitchen
Two facts are worth having before you sand or open a can.
- ●First, older cabinets can carry lead in their existing coatings. Canada now caps total lead in new consumer surface coatings, including furniture, at 90 mg/kg under Health Canada’s Surface Coating Materials Regulations, but coatings applied decades ago predate the modern limits. If your cabinets are old and you are about to sand them, wear a proper mask, control the dust, and test the old finish first if you have any doubt.
- ●Second, the paint you buy in Canada is already regulated for what it puts into your air. The Volatile Organic Compound (VOC) Concentration Limits for Architectural Coatings Regulations, SOR/2009-264, made under the Canadian Environmental Protection Act, cap the VOC content of the coatings sold here. A low-VOC cabinet enamel still has an odor while wet, so ventilate the kitchen and give the space air until the smell is gone.
Come and open the drawers, feel the boxes, and see painted and stained doors in real light. Monday to Friday, no appointment needed.
When Painting Kitchen Cabinets Is Worth It, and When New Doors Cost Less
Here is the honest part, and I will say it even though we sell cabinets. Painting is the right answer more often than a cabinet dealer would like to admit. A color change on sound boxes and real wood doors is one of the best-value upgrades in a kitchen.
The question is what you are actually painting over. A repaint refreshes the color, and does nothing for a tired hinge, a sagging drawer, a swollen box, or a layout that never worked. When those are the real problem, paint hides the symptom for a season, and the underlying kitchen keeps aging underneath.
Compare the ten-year cost. The weekend price is only part of the story. A careful DIY repaint runs a few hundred dollars in materials plus a couple of days of your labor.
New cabinets are a larger number: most full kitchen cabinet packages we sell fall between $5,000 and $25,000 CAD, roughly $350 to $700 per linear foot, flat-packed and before HST (15% NB) and installation. That larger spend buys back the boxes, the soft-close hinges and slides, and a factory finish at the same time, which a repaint cannot do.
Use this to place yourself honestly.
| If you are… | Painting your existing cabinets makes sense | New factory-finished doors or cabinets make sense |
|---|---|---|
| Working with sound plywood or solid wood boxes and real wood doors | You are a strong candidate for a repaint | Only if you also want a layout or storage change |
| On a tight budget and comfortable with careful prep | A DIY repaint is the best value on the board | Not yet, unless the boxes are failing |
| Refreshing a rental or a short-term home | A repaint gets you the look for the least money | Hard to justify the spend |
| Looking at thermofoil or peeling laminate doors | Paint will not hold reliably on these | New doors are the durable fix |
| Dealing with swollen, water-damaged, or racked boxes | Paint cannot repair structure | New boxes reset the problem properly |
| Fighting worn hinges, sticking drawers, or a layout that no longer works | A repaint leaves all of it in place | New cabinets solve the finish and the function together |
At BluePrint, we sell framed, ready-to-assemble cabinets with 5/8″ plywood boxes and 3/4″ solid birch face frames, and soft-close hardware standard on every cabinet under a limited lifetime hardware warranty. Our painted door styles, Shaker White, Shaker Grey, and York White, are a high-density fibreboard frame with an HDF center panel, chosen because HDF takes a factory paint finish beautifully and stays flat.
To be clear about what we do and do not do: we supply new cabinets and doors, and we do not refinish or paint the cabinets you already own. If a repaint is genuinely your best move, paint them, and keep this guide handy.
How to Decide Without Regret
If you are on the fence, spend twenty minutes on the boxes before you decide anything. Open and close every door and drawer, push on the sink-base floor, and look at the bottom edges of the doors nearest the dishwasher and the kettle for swelling. Knock on a box side and listen: solid plywood answers with a tight, dense sound, and hollow particleboard answers thin.
If the bones are good, paint with confidence and follow the steps above. If the boxes or hinges are the real story, a repaint is lipstick on a problem that will keep costing you. That is the same test I ran on my own 30-year-old kitchen before I gutted it, and the boxes lost.

The Bottom Line on Painting Your Cabinets
A cabinet repaint lives or dies on prep. Degrease it, dull the gloss, prime with a bonding primer, build the color in thin coats, and give it real time to cure. Do that on sound boxes and the finish holds up to daily cooking for years, for the price of materials and a weekend.
The only trap is painting over a problem paint cannot fix. If the doors are thermofoil, the boxes are swollen, or the hinges and layout are worn out, put the money toward doors or cabinets that reset the kitchen instead. Bring your measurements to the showroom or start a free layout online, and we will tell you honestly which way to go, even when the answer is paint.
