Using contact cement: The simplest method to employ is to apply a coat of cement to both surfaces to be bonded. Let the pieces dry. When the finish gloss is gone, press both pieces together.
Preparing Cork:To get superior results with contact, I recommend creating “prepared” cork. Since cork is porous, I can get best results by preparing the cork with three thin coats of cement. Let the cork dry completely between coats, allowing about 45 minutes. Prepare as much cork this way as you will use over two weeks time.
Using Prepared Cork For Joints: When it is time to use the cork for joint and neck corks, apply a fresh thin coat to both surfaces. The fresh coat will bond to the previous coats and you will have a superior bond.
For Keys: To use prepared cork for key work, you may use it as with joint corks, or heat the key part- then while warm apply a thin coat of cement to the key. Use one of our pipe cleaners to apply this cement. While still warm to the touch, press the previously prepared cork to the key, and trim. The heat activates the three old coats of cement and the fresh coat on the key bonds it quickly.
