perimeter of the cut or hole and the corners are well radiused.
c) Next hold the patch on the tube and mark out around it with a pencil.
d) Use a grinder, course sand paper or scratch stone, rough up both the back of the patch and the area
marked on the tube.
e) Clean both surfaces with solvent and spread a thin layer of adhesive over them ensuring there are no
lumps.
f)
When the first coat is dry to the touch (about 10 to 15 minutes) apply a second thin coat. After waiting 5
or 6 minutes, touch the adhesive with the back of your hand. If it no longer appears wet, heat both areas
with a hot air gun to re-active the glue and join the patch to the tube and then clamp or roll the surfaces
together. For the best adhesion, roll over the patch with a roller or over the bottom edge of a bottle.
Danger
Glue and solvent used for repair are highly flammable. Perform repairs in a well-ventilated area. Avoid breathing
the vapors, wear protective gears (goggles, filter respirators, latex gloves).
