Yes, you can paint melamine cabinets, and the result can last for years. But melamine is one of the hardest surfaces to coat, because it is slick, sealed and built to repel liquids. Ordinary wall paint on a wiped-down door will peel within months. The work that matters is mechanical sanding, a true bonding primer and a durable topcoat, applied in thin coats and given time to cure.
This guide walks through the process step by step, explains where DIY jobs usually fail, and tells you when it makes sense to hand the doors to a professional crew.
TL;DR
- Melamine can be painted, but only with a scuff-sand and a high-adhesion bonding primer. Regular interior paint over a cleaned surface will not hold.
- Sanding is not optional. Liquid deglossers alone often lead to peeling, especially near the dishwasher and oven.
- Use thin coats of primer and a hard-wearing cabinet enamel, then respect the cure time before the doors go back into daily use.
- Check the edges and any chipped or swollen spots first. Painting will not fix damaged particleboard.
- If you want a factory-smooth look on a whole kitchen, a sprayed finish by a pro usually beats a roller and brush job.

Why melamine resists paint
Melamine cabinets are usually particleboard or MDF covered with a resin-impregnated paper that is heat-cured under pressure. The surface is hard, glossy or satin, and non-porous. Paint normally grips by soaking into a surface or by biting into a rough one. Melamine offers neither.
CompositePaint’s melamine guide puts it bluntly: the material is engineered to refuse paint, so one bonding primer and one durable topcoat are what make the finish last. That matches what we see in kitchens across the GTA: when a melamine paint job fails, the cause is almost always the first step, not the colour on top.
Is it worth painting melamine cabinets?
It depends on the condition of the boxes and what you want from the kitchen.
Painting makes sense when:
- The cabinet boxes are solid, level and dry, and the layout works for you.
- The finish is dated (white, almond, faux wood grain) but not damaged.
- You want a new colour without the cost and mess of a full replacement.
Painting is the wrong call when:
- The particleboard core has swollen around the sink or dishwasher. Water-damaged substrate keeps moving, and paint cracks over it.
- The laminate or melamine skin is lifting off in sheets. Paint will not re-glue it.
- You are planning to change the layout anyway.
If you are weighing options, our guides on cabinet painting versus refacing and painting versus full replacement lay out the trade-offs for GTA homes. For budget thinking, see what cabinet painting costs.
Melamine, laminate or thermofoil: know what you have
Three different surfaces get confused, and they behave differently.
| Surface | What it is | How it feels | Paint difficulty |
|---|---|---|---|
| Melamine | Resin-saturated paper fused to particleboard or MDF | Hard, smooth, slightly glassy | High, needs sanding and bonding primer |
| High-pressure laminate | Thicker layered sheet glued to a core | Hard, often textured | High, similar prep |
| Thermofoil | Vinyl film heat-moulded over MDF | Slightly softer, wraps around profiles | Risky, the film can peel with heat |
If your doors have routed profiles or a wrapped, seamless edge, you probably have thermofoil, not melamine. That is a different job, and we cover it in painting thermofoil cabinets: what works. Most flat-panel melamine boxes from the 1990s onward, and many budget and builder-grade kitchens, are true melamine.
What to check before you start
Spend ten minutes on inspection. It saves a ruined weekend.
- Edges. Look at the edge banding on doors and drawer fronts. If it is lifting, re-glue it and let it dry before sanding.
- Swelling and chips. Press around the sink base. Soft or puffy board needs repair or replacement.
- Grease. Cabinets near the range carry a film of cooking oil you can barely see. It will defeat any primer.
- Heat zones. Doors beside the oven, above the kettle or next to the dishwasher are the first to fail. Plan for extra care there.
- Hardware. Decide now whether you are keeping existing hinges and pulls. Filling old holes means one more repair step.
How to paint melamine cabinets, step by step
1. Remove doors and label everything
Take off the doors, drawer fronts and hardware. Number each door and its matching opening with painter’s tape. Paint the doors flat on a table or sawhorses so you can control drips.
2. Degrease thoroughly
Wash every surface with a degreasing cleaner and rinse with clean water. Let it dry fully. Do this before sanding, otherwise you grind grease into the scratches.
3. Scuff-sand mechanically
This is the step people skip. Professional refinishers describe scuff-sanding with roughly 220-grit abrasive pads to give the coating a physical anchor, and warn that skipping it or relying on liquid deglosser alone often ends in peeling near heat sources. The goal is a uniform dull surface, not deep scratches. Some retail guides suggest slightly coarser paper, around 120 grit, so test on the back of a door and keep the pressure light to avoid cutting through the melamine skin.
Wipe off the dust with a barely damp cloth, then let it dry.
4. Fill and repair
Fill chips and old hinge holes with a two-part filler suited to particleboard. Sand flush, and spot-prime the repair.
5. Prime with a true bonding primer
This is the heart of the job. You need a primer made for hard, glossy surfaces, not a general-purpose latex primer.
- Sherwin-Williams describes Extreme Bond as a waterborne, urethane-modified acrylic primer designed for hard, slick, glossy surfaces with minimal surface preparation.
- CompositePaint’s review of INSL-X Stix calls it a bond coat for cabinets, laminate, melamine and thermofoil, and says standard latex, oil-based or shellac-based primers often lead to poor adhesion, peeling or yellowing.
In an independent test on the Decorators Forum, every primer tried struggled on melamine when the surface had not been keyed first. The lesson holds regardless of brand: the sanding and the primer work together.
Apply one thin, even coat with a fine foam or microfibre roller, or spray it. Do not try to hide the old finish in one heavy pass. Thick primer sags and cures poorly.
If your kitchen has stains from smoke, water or tannins coming through, a stain-blocking layer may also be needed. Our note on stain-blocking primer in Canada explains how to match it to the stain.
6. Lightly sand the primer
Once the primer is dry to the manufacturer’s recoat window, sand it very lightly with fine paper (320 grit or finer) to knock down dust nibs. Wipe clean.
7. Topcoat in thin layers
Use a hard-wearing cabinet enamel, such as a waterborne urethane-alkyd or acrylic-urethane. Two thin coats beat one thick coat every time. Sand lightly between coats if the product calls for it. Behr’s cabinet guidance also stresses scuff-sanding or deglossing previously glossy surfaces for proper adhesion before painting.
8. Let it cure, not just dry
Dry to the touch is not cured. Most cabinet enamels take days to harden and weeks to reach full durability. Keep doors off their hinges for at least a day, hang them gently, and leave the first week or two free of scrubbing, tape and heavy loading. In a cold, dry Ontario winter kitchen, or a humid July one, cure times stretch, so follow the data sheet for your product.
Common mistakes that cause peeling
- Painting straight onto melamine. Paint alone has nothing to grip.
- Relying on liquid deglosser. It dulls the shine but does not create a mechanical key.
- Using the wrong primer. Shellac or standard latex primers can look fine for a week, then lift.
- Heavy coats. They trap solvent or water and stay soft.
- Rushing the cure. Fingernails, pot lids and wet cloths will mark a half-cured finish.
- Ignoring edges. Doors fail at the corners and edges first, where wear is highest. Sand and prime them with the same care as the faces.
We also have a separate piece on painting cabinets without sanding. On melamine, treat any no-sand claim with caution: sanding is the safest route.
Spray, brush or roller?
A foam roller and a quality brush can give a decent result if you work slowly. Roller texture and brush marks are the usual giveaways, and melamine’s flat panels show them clearly.
Spraying is different. A sprayed finish lays down evenly, leaves no brush marks and builds a smooth film on flat doors. It needs masking, ventilation and a way to hang the doors while they dry, which is why it is often done off-site or in a controlled setting. If you want to see what that looks like, our article on cabinet spray finishing for homeowners explains the process.

Perspective: what we see on GTA melamine jobs
We get calls every month from homeowners who tried a weekend paint job on melamine and watched it chip around the handles within a season. Almost every time, the story is the same: a cleaned surface, a general-purpose primer and a good topcoat that had nothing solid underneath it.
Our view is simple. Melamine is a prep job first and a painting job second. We scuff-sand every door, use a bonding primer made for slick substrates, and protect your home with full prep and cleanup around the work. We also tell people honestly when painting is the wrong answer: if the core is swollen from a leak, or the layout is changing, paint is money wasted.
We offer a free colour consultation, because the colour you pick on a melamine door matters more than people expect. Flat panels with no profile show every shade shift and every sheen difference, so a slightly warmer white or a lower sheen can make a plain box look intentional. We also stand behind our work with a written workmanship warranty, which is the kind of promise you should ask any painter for before signing.

When to hire a professional
DIY is realistic for a small laundry room or a vanity. A full kitchen is different. Count the doors: a typical kitchen has 20 to 40 doors and drawer fronts, each needing washing, sanding, priming and two coats on both sides, with drying time between. That is a lot of floor space and many days of a kitchen that cannot be used normally.
Consider a pro when:
- You want a sprayed, factory-smooth finish.
- You are listing the home and need a clean result on a deadline.
- The doors have chips, swelling or lifting edges that need repair first.
- You are a landlord or property manager with several units to turn over.

FAQ
Can you paint straight onto melamine?
No. Paint applied directly to clean melamine has nothing to grip and typically peels or scratches off. You need to scuff-sand the surface first and then apply a bonding primer made for slick, non-porous materials before the topcoat.
What is the best primer for melamine?
Choose a urethane-modified acrylic bonding primer designed for glossy, hard surfaces. Product data from Sherwin-Williams describes this type of primer, and reviews of INSL-X Stix show it is widely used for melamine. Standard latex, oil or shellac primers are the wrong tool here.
Is it worth painting melamine cabinets?
Yes, if the boxes are sound and dry and you only want a new look. It costs far less than replacing cabinets. It is not worth it when the particleboard is swollen or the melamine skin is peeling away, because the paint will fail with the substrate.
How long does painted melamine last?
With proper sanding, a bonding primer and a hard cabinet enamel, painted melamine can hold up well in daily use, though no painted cabinet is as tough as the original factory surface. Doors near the dishwasher, oven and sink will wear first, so treat them gently and wipe spills quickly.
Can I paint melamine without sanding?
Some products promise minimal prep, and Sherwin-Williams lists Extreme Bond as needing minimal surface preparation. Still, professionals recommend mechanical scuff-sanding, because it cuts the risk of peeling, especially near heat.
