Krylon Fusion All-In-One Adhesive Spray Paint for Indoor/Outdoor Use, 12 oz, Black

Why I reached for Fusion

I had a mixed bag of projects lined up: refreshing a scuffed metal music stand, bringing a tired plastic storage bin back to life, touching up a patch of PVC trim, and giving a small wood planter a weatherproof coat. I wanted a single rattle can that could stick to all of it without a separate primer and still hold up outdoors. That’s what pushed me to Krylon’s Fusion in black. It’s billed as an all-in-one, bonds-to-anything spray that dries fast and protects against rust. After a few weekends of use, I’ve got a clear sense of where it shines and where you’ll want to slow down and adjust your technique.

Setup and surface prep

“Bonds without sanding” is the headline, and to its credit, Fusion grabs surprisingly well on tough substrates. That said, a few minutes of prep pays off:

• Plastic (polypropylene bin): I washed with dish soap, dried, then wiped with isopropyl alcohol to remove any residue. No sanding.
• Metal (music stand): I knocked down rough edges, brushed off light rust, and wiped clean. No dedicated primer.
• PVC trim: Degreased and dried.
• Wood planter: Light scuff with 220 grit to knock down fuzz, then dusted off.

On glossy tile and glazed ceramics, I tested a quick pass on a scrap. The first coat wanted to bead slightly. A light scuff with a fine pad or a liquid deglosser made the paint lay down better. You can skip sanding for many surfaces, but on very slick, glassy finishes, a bit of tooth improves both flow and durability.

Application experience

The nozzle on Fusion is easy to control. It produces a medium-fine fan with good atomization, and it didn’t spit or sputter on me as long as I kept the can shaken frequently. The paint lays down on the heavier side compared with some lighter-bodied enamels, which works in your favor if you prefer fewer passes—but it also means you should resist the urge to linger. Two or three quick, overlapping passes look better than a single heavy one.

A few practical notes:
- Shake longer than you think—full minute before starting, a quick shake between passes, and especially as you near the end of the can.
- Maintain 8–10 inches of distance. Too close and you’ll introduce sags; too far and you’ll get dry spray.
- It continued to spray consistently at moderate angles, handy for awkward inside corners, though I still avoid going fully upside down.
- Clear the nozzle after each session with a brief purge spray while the can is inverted.

Odor is what you’d expect from a solvent-based aerosol—noticeable and not something you want to use in a closed room. Ventilation and a respirator are smart here.

Coverage and color

For a 12 oz can, coverage is solid. With two light-to-medium coats, I got roughly 15–20 square feet of real-world coverage, depending on how porously the surface drank the paint. The satin black I used leveled to an even, rich black without visible banding or tiger striping. On the music stand, the finish was consistent enough that the repaired areas blended convincingly with the original factory look.

If you’re tackling larger items (like a door or a full patio set), plan on more than one can. Aerosol math catches everyone at some point; buying an extra saves you from mismatched batches or sheen variation if you have to come back later.

Dry time and recoat window

Fusion’s dry times lined up closely with the label in mild conditions. At around 68°F and under 50% humidity:
- Dust-free in roughly 10–15 minutes
- Tack-free to the touch around 20–30 minutes
- Comfortable to handle at about 2 hours

I put on subsequent light coats once the previous coat flashed off—usually within 10 minutes. The paint feels deceptively durable early, but it continues to harden over the next day. Give it a full 24 hours before heavy handling or masking over it, longer if humidity is high or temperatures are outside the sweet spot (55–75°F, under 60% humidity).

Adhesion and durability

This is where Fusion earns its name. On plastics—especially the kind that traditionally shrug off paint—it stuck better than most all-purpose aerosols I’ve used. I ran a simple crosshatch tape test on the plastic bin after a 72-hour cure, and the paint stayed put. On PVC, it latched on with no drama and didn’t chip from casual bumps.

Metal is Fusion’s other strong suit. After a light mechanical clean-up (no primer), the music stand took the paint smoothly. I left a small metal bracket outdoors for a few weeks of early summer sun and rain. No rust bleed-through or peeling showed up, and the black held its color. It’s still paint-on-metal without a separate primer, so if you’re dealing with deep rust or a high-traffic metal surface, more thorough rust prep or a dedicated rust-inhibiting system will outlast any single-step aerosol. But for touch-ups, brackets, hardware, patio accessories, and the like, Fusion’s protective layer is convincing.

On wood, the finish looked uniform and felt tougher than typical hardware-store enamel. It won’t replace a marine-grade system for deck furniture exposed to harsh conditions, but for planters, trim, and accent pieces, it’s plenty.

Finish quality

Applied with reasonable discipline, Fusion can deliver that desirable “dipped” look—especially on small parts and accessories. It levels nicely and hides minor imperfections, and I didn’t experience orange peel unless I sprayed too far away or into a warm, dry breeze. The sheen held consistently across coats, and the final film felt cohesive rather than chalky.

If you want a little extra insurance on high-touch areas (handrails, grab handles, tool grips), a compatible clear coat adds abrasion resistance. I’ve had good results spraying a light clear after 1–2 hours while the color coat is still within its recoat window, then letting both cure together for a day.

Practical limitations

• Ventilation: The fumes are strong; outdoors or a well-ventilated shop with a respirator is best.
• Humidity and temperature: Performance tracks the conditions. Outside the 55–75°F, <60% RH window, expect slower dry times and an increased risk of blush or dulling.
• Overspray: The fan pattern is generous. Mask more than you think you need to, and use a cardboard shield to control edges.
• Ultra-glossy surfaces: It will stick, but a quick scuff or degloss improves the result and helps prevent chipping.
• End-of-can sputter: As with most aerosols, you’ll get a slight pressure drop and coarser spray near empty. Plan your final coats before you’re running on fumes.

Who it suits

• DIYers who want a single can to cover mixed materials without juggling primers
• Anyone tackling small to medium outdoor projects where rust protection matters
• Apartment and garage users who value fast dry and minimal downtime between coats
• Teachers, musicians, and facilities managers touching up black-coated metal fixtures and stands

If you’re painting large flat surfaces where absolute uniformity is critical, or you’re dealing with severe rust remediation, you’ll likely want a more specialized system. But that’s outside the intent of an all-in-one aerosol.

The bottom line

Fusion does what many multi-surface sprays promise but often miss: it adheres tenaciously to plastics, metal, wood, and PVC without a primer step, it dries fast in reasonable shop conditions, and it leaves a durable, even finish that holds up outdoors. The nozzle is predictable, coverage per can is respectable, and the black lays down rich and consistent. Respect the usual aerosol best practices—clean surfaces, light overlapping coats, patience for a full cure—and you’ll get a finish that looks like more work than it was.

Recommendation: I recommend Fusion for anyone needing a reliable, single-can solution across mixed materials, especially for outdoor touch-ups, small furniture, fixtures, and accessories. Its combination of adhesion, rust resistance, and fast dry time makes it a dependable choice. Just budget for an extra can on larger pieces, prep glossy surfaces lightly, and give it the ventilation and cure time it deserves.
