Apply patch When the adhesive has become tacky, peel off the backing of the patch and centre the patch on the marked up hole. Press it down firmly, working from the centre outwards. If the repair is good, the patch will stretch with the tube, if not repeat the process again. When firmly bonded to the inner tube, scatter dust or chalk around the patch (many puncture repair kits come with chalk which can be ground in, or use any available dust), this will prevent any adhesive sticking to the inside of the tyre. Re-fit the inner tube as per Step 5 and pump the tube up to full pressure.
