How to Seal Air Pressure With Epoxy
- 1). Prepare the surface for the epoxy by wiping it down with a dry cloth. If the surface is dirty or soiled in some way, you may use a wet cloth to clean it up, but make sure the surface is entirely dry and clean before applying the epoxy.
- 2). Place another dry towel underneath the surface that is to be sealed if possible. When using epoxy, you should also be in a well ventilated area because of the fumes that the epoxy gives off.
- 3). Put on rubber gloves that will protect your skin from the epoxy before mixing it. For air-tight sealing, you should use a paste epoxy, as the liquid epoxy is primarily meant for lighter jobs. Because there are many different kinds of epoxy, you will have to follow the instructions that come with the epoxy mix in order to make it correctly.
- 4). Fill an industrial epoxy injector with the mixture. Do this while still wearing your gloves as this process can be dirty.
- 5). Apply the epoxy to the area that you are sealing. Make sure the first injection is directly in the center of the crack or crevice so you have room for additional seals.
- 6). Wait for the epoxy to dry according to the label instructions. Once the first layer is dry, repeat the process two to three times for maximum airtight results.
