If you’d like to jazz up your outdoor space, but a brand new patio set isn’t in your budget, consider refinishing your rusty patio furniture (or a set you found at the thrift store!) with spray paint. It’s a weekend project that yields beautiful results!
I started with this folding bistro table. It still functioned perfectly, but the paint had worn off in spots, leaving the metal frame underneath rusted in a few places and exposed to the elements. In order to refinish the piece so that it will last many years to come, you’ll need to remove as much of the rust from the frame as possible.
To get started, you’ll need:
- An electric sander with sandpaper in varying grits (I used sandpaper in 60, 150, and 220 grit)
- Rust-Oleum Professional Aerosol Primer, 2 cans
- Rust-Oleum Stop Rust Protective Enamel Spray Paint in Hunter Green, 2 cans
- Wet sanding paper (optional)
Tip: When I first began this project, I was using sandpaper blocks, no electric sander, but within a couple of minutes, it was clear that the sandpaper blocks weren’t going to get the job done. Just know that if your goal is to sand off most of the rust, an electric sander is the only option. (If you don’t own an electric sander, consider renting one at your local Home Depot store).
When trying to decide which grit of sandpaper to use, remember that the lowest grit means that it’s the most coarse, so 60 is going to remove the most finish. The higher the grit, the finer the sandpaper, so you won’t really be removing much debris, just smoothing out the surface. When you see the term ‘going through the grit,’ that just means that they’re beginning with the lowest grit sandpaper, taking off the most debris, and gradually getting finer and finer, therefore smoothing out the surface for a really clean finish.
I sanded this tabletop for several hours, probably about 5 in total, as I wanted to really scuff off as much rust as possible, and reveal the shiny metal frame underneath. By getting down to the original frame, the chance of rust coming back is much lower, and also the finish will be much smoother once the spray paint dries.
Here, you can see where several layers of paint had been applied to this table, one much darker than the other. I wanted to remove as much of the paint as possible, and I focused most of my sanding on the patches that you can see along the edge of the table and just inside.
You can see that after a while, I started to get down to the bottom layer, where the rust first started. I eventually removed all of the rust from this patch (and all the patches like it on the edges and table top), revealing the shiny metal frame underneath.
Once I finally reached that metal frame and the edges were smooth, it was time to apply primer. Rust-Oleum’s primers are specifically designed to fight rust and prepare bare metal for spray paint. When spraying, coat the furniture in very, very light coats. The first few coats should appear almost patchy, like a mist. You shouldn’t have full coverage until you’re at about the third coat.
Below, you can see the first of many coats of spray paint on the table. See how it appears almost splotchy? That’s good!
Tip: If you’re painting outside, there’s a chance that some kind of debris could fall on your wet surface, leaving marks in your paint job. If this happens, remove the material and use wet sanding paper to smooth out the surface. Wet sanding paper uses water to create the smoothest possible finish, and it’s perfect for small imperfections.
Once the final coats are spray painted, you should let the table cure for a full 24 hours, just to be safe, before putting any hard objects on it. Leave the table underneath a covered surface over night so nothing can fall on top of it and ruin the paint job.
Refinishing rusty patio furniture takes a little elbow grease, as they say. But once your piece has finally cured and is beautifully refinished, your patio table should last for many, many more glasses of lemonade, casual dinners, and relaxed sunny afternoons.
