Easy-to-follow, Step-by-step Tube Repair

Repairing a damaged inner tube can be a cost effective way to extend the service life of an otherwise usable tube. With the proper tools and supplies, the process is straight forward and relatively simple to perform. Here are the basic tools and step-by-step instructions needed to perform the repair.

Step 1: Inspect the tube for injury.

Step 2: Check the injury. Button hole or round out the ends of the injury to prevent future tearing of the tube. To prevent chaffing, trim a small strip (about 1/16") off the length of injury.
Step 3: Clean tube surface by spraying a coat of pre-buff cleaner over the injured area. Allow it to set for approximately 10 to 15 seconds. Drag the scraper over the entire sprayed surface to remove contaminants. Repeat if necessary.
Step 4: Choose a tube patch that will extend beyond the injury by at least ½".
Step 5: Buff the area slightly larger than patch size, to a smooth velvety surface. Do not use a buffer that exceeds 5,000 RPM. A high-speed buffer scorches the rubber prohibiting an optimum bond.
Step 6: Use a metal bristle brush to remove any buffing dust.
Step 7: Apply a thin coat of Rema cold vulcanizing fluid to the entire buffed area. Do not over-apply. Allow to dry thoroughly. Test with back of your finger, outside of the repair area. When cement is tacky, but does not stick to your finger, the cement is ready.
Step 8: Peel foil backing from the patch. Center the patch over the injury. Press the patch down on the tube, using pressure at the center and working out to the edge.
Step 9: Using the stitcher, press down firmly, starting in the center and working to the outer edges to remove any air that may be trapped under the patch.
Step 10: Peel off plastic covering. Cover the entire buffed and cemented area with tire talc to prevent damage to the tube.
Step 11: Put a small amount of air in the tube to check the repair before installing it in the tire.


Do's and Don't of Tube Repair
Do's Don'ts
Always use one complete system. (All products and instructions from one manufacturer.) Use or mix products from different manufactures. Example: Rema patches with Camel cold vulcanizing fluid, or Tech patches with Rema cold vulcanizing fluid.
Button hole the ends of a cut or slice to stop tearing. Put a patch on a tube that is inflated. Install when the tube is deflated.
Always use pre-buff cleaner and a scraper to remove the contaminants from the tube. Do not use a cloth or paper towels. Use air pressure to blow dust from the tube after buffing. Air from air lines can contain moisture and oils which may cause a poor bond between the patch and vulcanizing fluids
Repair tube in a clean, warm, dry area. Avoid high moisture or cold temperatures.
