A water-resistant sofa lets the good times roll.
When you live in a college town like I do in Berkeley, California, you see a lot of couches on the porches of partied-out frats and rental houses. I can dig it, but those things get nasty after a few semesters of drinkin’ and relaxin’. The upholstery and wood just aren’t cut out for damp weather and bugs. Surely, I thought, there has to be a sofa that can sit out on a porch and fulfill its duty. I just happened to have a midcentury-style sofa in my storage room that my former cat, Daisy, had scratched to hell. It was perfect to test my outdoor-living idea. I did some demo on the old thing, covered the remains in billboard tarp, and plopped it in a new frame. Here’s to
el sofa del aire libre!
Step 1:
The first order of business was dissection. I removed the wood base and ripped-up arms of my old couch. Your couch may be constructed differently, so your design may shape up differently too. I also scrounged up two old doors and two 2×6 boards so I could build a new frame.

Step 2:
I decided to re-cover the seat and back with a section of an old billboard tarp—look for it online. The great thing about this material is that it’s nonmildewing so moisture won’t affect it. To begin the covering, I stapled the tarp to the front underside of the seat frame. Next, I covered the sides and back, then back around to the bottom, covering all surfaces. This is a no-sew method, like stretching a canvas.

Step 3:
I wanted to fancy up my design with a new frame. Sections of a five-panel solid door started things off. I used my table saw to cut two panels from the door—one for each side of the frame. (Be careful and keep an eye out for old screws, nails, etc. No cutting them, please!) The 2×6s make a simple bottom. Just cut them to the length you want, then join them to the upright sides at the inside front and back, with good-size screws and two-part epoxy. I counter-sunk the screws and filled in with wood plugs adhered with water-resistant wood glue. For the back, I cut the other door to fit the partially assembled frame and attached in the same manner. Be as “craftsmanly” as you want with the woodworking. Go for super-tight joinery or don’t worry—just make sure the connections are strong.

Step 4:
After a good sanding and wood filler here and there, the frame is ready to paint. I took the time to remove the old paint, but you decide if your couch warrants the effort. I didn’t want to be too fussy with the finish, but I wanted a solid sealing so the wood could withstand moisture. My quick-and-dirty finishing started with exterior pigmented shellac primer in a spray can. The stuff dries quickly and is great for creating a good base for the paint. After it dried, I spray-painted on a green exterior paint. Take care not to lay it on too heavy because spray paint runs easily. Plan on more than one coat. Just keep going over the entire piece until the coverage is even. Practice and patience, my friend.
Step 5:
Time for the legs—just some aluminum tubes I had around. I cut them on my chop saw. (To cut nonferrous material, make sure the woodworking tools are sharp and of high quality. I used a triple-chip blade with a 10-degree angle. Ask a hardware-store professional if you’re not sure.) I attached the legs with slip-on pipe fittings. Mine were Speed-Rail connectors, available online.

Step 6:
I flipped the beast upright and lowered the old (but newly covered) seat and back into the new frame. A perfect fit! Then some screws to attach the bottom of the seat to the frame. Done! But what about throw pillows? I did some quick sewing with the tarp and Naugahyde pulled off the old couch, then stuffed the squares with batting so the couch is now nicely appointed. After that I’m tired, I’m cracking a cold one, feeling sleepy … yawn … see you next issue … zzz.
