Preparing Air Jordan 4 Midsole for Repainting

We continue with the Air Jordan 4 Midsole Swap Project by showing you how to prepare the midsoles for repaint. I know you're eager to see the repaint vid, but we have to show you how to prep the stuff first. And honestly, this deserves it's own video. To prepare the midsole, you'll need the following materials
  • Acetone or nail polish remover
  • Container
  • Gloves
  • Cotton Squares or Cotton Balls
  • Cotton Swabs AKA Q-tips
  • Masking tape
We chose to use acetone over nail polish remover since the latter just isn't strong enough. Nail polish remover will work, but as shown in the video, it doesn't strip the paint as fast and effectively as acetone. But if you're restoring on a budget, you may have to go that route. You will definitely need a container to hold the acetone in. One thing to note is that you'll find your acetone evaporates very quickly. This is due to the fact that acetone has weak molecular bonds along with a low boiling point temperature of 57 degrees Celsius. For reference, water has a boiling point of 100 degrees Celsius.

Gloves are very important, especially working with harsh chemicals. You've been warned.  The other important tool you'll need are cotton squares or balls. Cotton squares just work better, so if you can afford and use them, get them. You'll use the cotton swabs for tiny areas where the paint is difficult to reach.

The masking tape is used to cover areas that aren't going to be painted. We recommend going name brand with something like Scotch 3m. Some have used painter's tape. The stuff just works better than the dollar store counterparts. Trust me, you'll save a ton of time and trouble using name brand tape.

To prepare your midsoles, first tape the areas that will not be repainted with masking tape. Use little pieces and use your thumb nail to line up the tape right on the edge where the paint meets the non painted region. Continuing using small pieces all the way around the midsole. You can even double layer the tape for extra protection.

Once you've masked the areas off, it's time to pour the acetone into a bowl. Make sure you're bowl is safe to use. Next, take your cotton square and dip it in to get a good saturation of acetone. Make sure you're wearing gloves! Then start wiping down on the paint by using a motion that moves away from the tape. You don't want paint to transfer on areas that it shouldn't be on.

And that's it. Just continue the process throughout the midsole. You can use the Q-tips to reach smaller areas that are difficult to reach with the cotton squares.
