Video: How to Patch Bicycle Tire Chamber

You will need a patch kit with glue, sandpaper and spatulas.

After accessing the camera, the first thing to do is to identify the hole. The ideal is to mark it somehow (a pen, for example).

Once the hole is identified, you should leave the camera fully stretched (see the movie below) using the back of your hand for support. If the hole is small and it is still slightly inflated, no problem. With this, the camera is more supported, taking the shape of the back of the hand.

After this step, we take the sandpaper (which comes with most of the camera repair kits available on the market) and scrape the area of ​​the hole to remove any impurity that may prevent the fixing of the patch.

Note that once the camera is fixed to the back of the hand, the ideal is that it is not looser, so there is no possibility of “losing” sight of the prepared area.
Then we started applying the glue (which comes with most of the camera repair kits available on the market) using the body of the glue package for the application. We should avoid using the finger in the application, so that the fat on the hand does not “contaminate” the area of ​​the repair, minimizing the adhesiveness of the patch.

After application, we wait for the glue to dry, which may vary according to the manufacturer. One tip is to perceive by decreasing the “brightness” of it. Generally when it is applied it becomes shiny, and as its drying takes place it becomes “opaque”. The loss of brightness then indicates the ideal drying point and from this proceed with our repair.
During this drying the camera can be removed from the position in which it was, being able to “rest” on some flat surface, avoiding contact with the region of the repair.

After drying the glue, we then use the “patch” itself (which accompanies most of the camera repair kits available in the market, and in São Paulo is called “estrelinha”), usually offered in one size or as a piece Large one whose size is defined at the time of application, cutting as necessary. The latter is more unusual but also present in the market.

Then remove the protective film from the patch, avoiding contact with the adhesive area of ​​the patch. We returned to “roll up” the chamber in the previous way (on the back of the hand) so that we have the support of the region to be patched and then apply the patch with the other hand in the place previously prepared.

After the patch has been placed, remove the top protective film from the patch by running your finger “over” the patch to prevent imperfections.

To avoid patching bicycle tire again, knowing how to select the best tire is necessary,
