Grind the location of the hole slightly until the surface feels a little rough.

Next, apply a thin coat of the rubber cement around the hole. The coat of cement should be about the same size as the patch.

For best results wait until the rubber cement is dry to the touch—around three minutes.

Finally, peel off the back of the patch, place it over the area of rubber cement with the hole centered, and then apply pressure with thumb until rubber cement is dry.
