How to Repair a Tire: a Step-By-Step Guide
Step 1: Clean the Tire Surface
The first step when repairing a tire is surface preparation. Start by brushing down the surface of the damaged tire to remove any loose contamination.
Step 2: Remove Loose Rubber
Use a suitable knife to cut away and remove any loose rubber to leave a sound edge.
Step 3: Abrade the Tire Repair Area
To ensure maximum adhesion, use a roughing brush to abrade the surface until you achieve a wooly finish. You should then brush away any loose surface contamination again before beginning the tire repair application.
Step 4: Apply Surface Conditioner
Apply Belzona 2911 (QD Conditioner) to the entire repair area of the damaged tire. This will need to be touch dry before applying the Belzona 2111 (D&A Hi-Build Elastomer).
Step 5: Mask off the Repair Area
Mask off the repair area with tape to ensure a neat application.
Step 6: Prepare the Two Components
Stir the Belzona 2111 (D&A Hi-Build Elastomer) Solidifier thoroughly to reincorporate any settlement. Then add the Base and Solidifier to a mixing bowl.
Step 7: Mix Thoroughly to Combine
Mix thoroughly for at least three minutes to combine the two components. You should then allow the mixed product to stand for a few minutes until a gel forms (please see table below and always check the Instructions For Use for up-to-date instructions). Use the mixed material in the timeframe shown below.
| Temperature | 50°F (10°C) | 68°F (20°C) | 86°F (30°C) | 104°F (40°C) |
| Time to gel formation | 7 ½ min. | 4 min. | 3 min. | 2 min. |
| Use all material within | 21 min. | 12 min. | 10 min. | 8 min. |
Step 8: Apply the First Layer of Belzona 2111 (D&A Hi-Build Elastomer)
Apply the product to the repair area firmly using a brush or a Belzona applicator. Be sure to brush the material well into the profile to achieve optimal adhesion.
Step 9: Add Reinforcement Tape
Cut and embed Belzona 9341 (Reinforcement Tape) into the first layer of Belzona 2111 (D&A Hi-Build Elastomer).
Step 10: Apply the Final Layer
Encapsulate the reinforcement tape with a final layer of Belzona 2111 (D&A Hi-Build Elastomer).
Step 11: Remove Tape and Allow to Cure
For the final step of this guide demonstrating how to repair a tire, simply remove the masking tape and leave your tire repair to cure.
