How to Polish a Barwa Frame

Specifically how Amanda went from “don’t bring that in the house” to “we should put the Barwa in our living room!”

A new cover and set of springs will go a long way in maintaining your Barwa chair’s use and beauty, but properly polishing the frame can make it look almost new. This post will walk through the method we used to polish our Barwa frame with just a few inexpensive supplies, some elbow grease, and patience. Our goal with this process is to bring your frame to its full potential, not necessarily remove every single scratch, ding, or imperfection on the frame. I found that bringing the metal to a nice shine helps hide some of the imperfections, and they’re only visible upon very close inspection. Depending on the specific condition of your frame, you may find that courser sanding grit is required for certain parts. Use your judgment and feel free to diverge from what’s recommended here based on your situation. If perfection is what you’re after maybe consider looking into having the legs chromed just as Edgar Bartolucci, one of the designers of the Barwa, did on his own personal chairs. Also, please leave comments if you have suggestions for alternative methods or other improvements that would be helpful to others.

The Process:

Polishing the metal of your Barwa frame works a lot like finishing wood except it’s more time-consuming as the material is harder. Essentially, there are three steps: cleaning, sanding, and polishing. Most of the time is spent sanding where we’ll work each piece of the frame through different grit levels of micro-mesh, starting with the roughest and ending with the smoothest. Each level is removing the scratches of the previous grit until the metal looks shiny and polished. Be advised, this can be a time-consuming activity. My recommendation is to take your time, enjoy the process because the results will be worth the work. Not only will this make the legs of the chair look incredible, but polishing the top of the frame will help the cover last longer. If you’re changing the cover on your chair, now is a great time to completely disassemble the frame a polish it up. This section of our YouTube tutorial is where I cover the polishing part. It’s not as detailed as this post, but I show different parts of the frame through the stages and you can see the results of this process.

Step 1: Disassemble and cleaning

We recommend fully disassembling the Barwa frame before you begin polishing. There are a total of ten bolts that will need to be removed. If the bolts are rusty and need to be replaced, the longer ones can be purchased at any hardware store, and the shorter 1 1/4″ bolts can be ordered online. The polishing process can be messy; wearing disposable craft or latex gloves will simplify some of the clean-up.

The chair in these photos was ~70 years old and had spent most of its life outdoors. We removed the initial layers of dirt by dipping 0000 steel wool in vinegar and scrubbing each piece. Dry each piece with a rag or towel before moving on to the next one.

Step 2: Sanding

Next, spread out each grit of micro mesh in order and we’ll work through each one starting with 1500. You’ll also need a small bowl of water to dip the micro mesh in periodically. Wet the first sheet of micro-mesh, hold the piece of the frame with one hand and start sanding in a long ways back and forth motion with your other hand. Take your time and sand all sides of the entire piece. Metal slurry will begin to form as you go; this is good and means you’re making progress. It’s good to wipe slurry off with a rag regularly and keep wetting the mesh. Once you’ve completely sanded the piece, wipe it down, and move to the next grit. We’re going to do this through nine levels of grit. Be patient, stick with it, and don’t slack on completely sanding the piece with each grit, it’s worth the result.

I’d recommend starting with the legs of the frame as the parts are smaller and easier to handle. Also, since this is the most visible part of the chair, it’s good to work on it while you have the energy. The top of the frame isn’t visible, so if you want to sand a little less on this part it’s totally fine. What’s most important with the top is to polish any rough spots that correspond to where the springs attach; some of these required rougher sandpaper to get smooth. The two that were really bad I used 300, 400, then 800 grit paper before using the micro mesh. The exact grits don’t matter but if rough spots have developed here, it may reduce the life of the cover. This is the one part of the polishing that’s structurally important and it doesn’t take long to fix as the spots are relatively small.

You can see three white spots that developed due to the friction & tension applied by the springs and the cover.
This was as good as I could get on the worst spot on my chair. While it doesn’t look perfect, it’s completely smooth to the touch and that’s what we’re after.

Step 3: Polishing the Barwa Frame

Now that we’ve gone through the micro-mesh, the surface will be super smooth but the finish will appear somewhat dull. This next step is really what makes it look incredible. We’re going to use a foam pad with some Meguiar’s Mirror Glaze and buff it using a drill. A dedicated buffer wheel can be easier and potentially safer, but a drill can produce very similar results and most people already have access to one. Place the piece of frame on a surface that won’t scratch. An old towel works fine, but be careful not to let the pad make contact with the towel as it can wrap around the drill very quickly and fling the piece of frame. I found applying the polish directly to the pad works best. A couple of slow turns will help spread the polish on the pad, then speed up the drill and let the polish do what it does best. Hold the frame piece firmly while polishing to make sure the drill doesn’t fling it. The pad will turn dark black, but don’t worry that’s expected and not a problem. After each side of the piece has been polished, use a clean cloth to remove any remaining polish residue. I also had an old bottle of Meguiar’s Quik Detailer and used that to help remove the polish residue. If you don’t already have some I don’t know that it’s necessary to buy, wetting a rag with water is likely to get the same result.

Now Enjoy Your Fabulous Frame!

I still can’t believe how well this turned out.

I spread this out over two weekends, so don’t get discouraged if you find your arms are getting tired from all the sanding. Just take breaks, go slow, and I promise it’s worth it. I mean, just look at those legs!!

All finished and reassembled.

Now, put your cover on and enjoy your beautifully polished frame that will look gorgeous for years to come!!
