Krylon Fusion vs COLORmaxx

The 30-Second Answer

Buy Fusion All-In-One when the surface is the problem and COLORmaxx when the color is the point. Fusion bonds to rigid plastic, PVC, metal, and wicker without sanding or priming, and it adds rust protection COLORmaxx doesn’t have. COLORmaxx carries the wider shade deck and four real sheens for a dollar or two less, and it grips fine on clean wood, clean metal, glass, and ceramic. Same 12-ounce can, same 20-minute touch dry, same seven-day cure. The plastic chair takes Fusion. The lamp base takes COLORmaxx.

That’s the whole decision, and it’s worth saying plainly because these two cans sit inches apart on the shelf in nearly identical livery. People reach for the one whose color they like and find out three weeks later that the paint had no interest in staying on a resin chair.

At a Glance

Read that table sideways and you’ll notice how much the two cans share. Same size, same coverage, same schedule, same self-priming claim. They separate on exactly two axes: what the paint will hold onto, and how many shades you get to choose from.

Surface by Surface

This is the table to actually decide on. Our reviews tested both cans across the substrates people bring them home for, and the pattern is consistent enough to shop by.

The one row worth reading twice is flexible plastic. Fusion’s label implies you can skip prep on anything plastic, and on the bendy waxy stuff — cheap lawn chairs, storage totes, a lot of toys — that’s the product’s biggest overreach. A clean, unsanded polypropylene lid peeled in sheets at a fingernail by week one in our Fusion All-In-One review. Two minutes with a maroon pad and an alcohol wipe fixes it. But it is a step, and the can suggests otherwise.

Adhesion

Fusion exists because plastic is too slick for ordinary mechanical adhesion. Most aerosol enamels rely on the surface having enough tooth to lock into; a molded resin chair has none. Fusion uses a bonding resin that grabs the substrate chemically instead, which is why it goes down on unsanded PVC and hard resin and stays there. That’s the real half of the 5X adhesion claim.

COLORmaxx isn’t trying to do that. It’s a paint-and-primer acrylic that self-primes on clean, dewaxed wood, metal, and rigid plastic and does it well. On the easy substrates you genuinely can skip the primer can, and that saves a step and a few dollars. Where it stops is anything slick, oily, or previously glossy. Bare rusty metal and factory gloss both need a scuff and a coat of the matching COLORmaxx Primer first, or the topcoat lifts at the first knock.

Winner: Fusion, decisively, and it’s the only reason the price gap exists.

Color and Sheen

Here’s where COLORmaxx earns its place on the shelf, and where I’d push back on anyone who treats Fusion as simply the better can.

COLORmaxx carries the wider deck — roughly 70-plus shades against Fusion’s 40 or so — and four true sheens: flat, satin, semi-gloss, and gloss. Fusion runs gloss, satin, and matte, with the metallic, hammered, and textured finishes living in separate lines. That extra sheen step matters more than the count suggests. Semi-gloss sits between satin and full gloss in a way that reads considerably calmer on a small object under a lamp, and Fusion simply doesn’t offer it.

The palette difference is real too. When a room wants a specific muted sage, a dusty slate blue, or a coral that leans warm rather than pink, COLORmaxx usually has it and the tougher cans usually don’t. Krylon tunes those shades for the craft channel, which is why the color reads cleaner in the can than the hardware-aisle equivalents. Our COLORmaxx review goes deeper on where that deck holds up.

Two things to hold in your head while you choose. First, sheen changes how a color sits in a room more than most people expect: a flat finish gives you the color with nothing to hide behind, so whatever undertone is in the can is what you live with at 4pm in November. Second, a north-facing room will cool almost anything you spray, so a grey that looked warm on the cap will drift blue on the shelf by the window.

Winner: COLORmaxx, on both palette and sheen freedom.

Durability and Sun

Neither of these is a long-haul exterior coating, and the honest version of this section is that they fail at different speeds rather than differently.

COLORmaxx cures into a thin film. That’s the recurring knock in our testing and in retail reviews, and the split tracks the surface precisely: people who sprayed frames and lamp bases are happy, and people who sprayed chair seats and gate latches report chips inside a year. Outdoors it’s a one-to-two-season coating despite the fade-resistance claim, with dark colors chalking and lightening after a couple of summers.

Fusion builds heavier and adds rust protection the older plastic-only formula never claimed, which shows up on a metal planter or a garden chair. But it hits the same wall in direct sun: dark colors visibly lose saturation and chalk by season two, and gloss and satin hold longer than matte in both lines. A fully exposed black metal chair went dull and faintly powdery by its second August.

If the piece lives outside permanently, the real answer is neither can. A brush-on exterior enamel holds color far longer, and the best outdoor furniture paint round-up covers what actually survives a few winters. Aerosol is the right tool for shape and detail, not for longevity.

One salvage move worth knowing: two light passes of a clear acrylic or polyurethane over cured COLORmaxx buys the abrasion resistance the color coat alone doesn’t have. It’s an extra can and an extra day, and it turns a borderline piece into a finish that lasts.

Winner: Fusion, though the gap is smaller than the price implies.

Dry Times and Handling

The schedules are identical, which makes this section short and the mistake within it common.

Both cans touch-dry in about 20 minutes, handle in an hour, and reach full cure at seven days. Both share the recoat rule that catches nearly every first-timer: lay the second coat within the first hour, while the film is still active, or wait a full 48 hours. Spray at the four-hour mark, right in the dead zone, and the solvent in the fresh coat wrinkles the half-set coat underneath. Krylon buries this on the label behind the paint-and-primer headline.

Tips differ slightly and both are good. Fusion’s wide EZ Touch fan sprays a soft-edged band that overlaps without stripes, which is what you want on a flat panel. COLORmaxx’s big-button tip sprays at any angle, even upside down, which is what you want under a chair rung or inside a planter lip. Neither clogs the way bargain cans do.

Coverage is the same on paper — about 25 square feet per can — and the same in practice, meaning two or three thin passes, never one heavy one. A small lamp or frame takes most of a can. A molded chair eats one to two. Buy one more than you think you need, because running out mid-coat and finishing tomorrow leaves a lap line you can’t sand out of a thin aerosol film.

Winner: Tie.

Price per Project

Fusion runs $6 to $11 a can depending on store and finish; COLORmaxx runs $5 to $9. Call it a dollar or two of difference, which is genuinely not enough to decide on by itself.

Where the money actually shows up is the redo. A COLORmaxx coat that peels off a resin chair costs you the can, the afternoon, and the sanding you’ll do before you respray with Fusion anyway. Going the other direction, paying Fusion prices for a set of indoor picture frames buys you nothing except a shorter color list. Multi-packs cut the per-can price on both lines, and they’re the smart buy for a chair set or a batch of frames in one shade.

Winner: COLORmaxx on sticker price. Fusion on any project where adhesion is the thing you’re actually buying.

Verdict by Use Case

• Pick Fusion All-In-One if: the surface is rigid plastic, PVC, resin, metal, or resin wicker; the piece is mixed-material and you’d need two products otherwise; there’s bare or lightly rusted metal involved; or you simply don’t want to sand and prime a slick substrate. Scuff flexible plastic first regardless of what the can says.
• Pick COLORmaxx if: the piece is indoor decor that gets looked at rather than handled — frames, lamp bases, baskets, vases, shelf brackets, thrifted wood — and the exact shade or the semi-gloss sheen matters to you. It’s the decorator’s can and it’s cheaper.
• Buy neither if: the piece bakes in full sun and you want to forget about it for a decade, or the plastic is flexible polyethylene or polypropylene and you won’t prep it. A brush-on exterior enamel wins the first case; a dedicated plastic bonding primer plus any color wins the second.
• It’s basically a tie when: you’re spraying a clean wood or metal accent that lives indoors and both lines carry your color. Buy whichever shade is on the shelf.

FAQ

What is the difference between Krylon Fusion and COLORmaxx? Fusion is the adhesion can, COLORmaxx is the color can. Same 12-ounce format, same 20-minute touch dry, same seven-day cure. Fusion bonds to slick rigid surfaces without sanding and adds rust protection on metal. COLORmaxx trades grip for a wider shade deck and four sheens, aimed at indoor decor.

Can I use COLORmaxx on plastic? On clean, dewaxed rigid plastic, yes. On the soft waxy plastics that bend under your thumb, it peels. That mismatch is the most common one we see. If the piece bends, buy Fusion and scuff it first anyway.

Is Krylon Fusion worth the extra money over COLORmaxx? Only when the surface is the problem. The gap is a dollar or two, which is nothing against a coat that fails. On clean wood, metal, glass, or ceramic, COLORmaxx grips fine and gives you more shades for less.

Which Krylon spray lasts longer outdoors? Fusion, but neither is a multi-year exterior finish. COLORmaxx runs one to two seasons on shaded pieces; Fusion holds longer on outdoor metal and rigid resin. Both chalk in dark colors by the second summer of direct sun.

Can I spray COLORmaxx over Fusion? Yes, and it’s a smart combination when the shade you want only exists in the COLORmaxx deck. Let Fusion do the bonding, let COLORmaxx do the color, respect the recoat window, and clear-coat anything handled.

One last note on color, since that’s usually the part people get wrong after they’ve got the adhesion right. Spray a test card and set it in the room the piece is going into, at the hour you actually use that room. A coral that sang under the store’s fluorescents can go pink on a north-facing shelf, and a whole can of the wrong warm grey is a slower lesson than a peeling chair.
