First, read the English article below.

Almost every outdoor store will have these in the camping section. They are small, cheap sets that contain glue, sandpaper, and patches for tents, bike tires, and air mattresses. If you are in a pinch and the hole is small, a tire patch made for cycling should work fine.  Some companies have dedicated air mattress repair kits that you can find online, such as the Thermarest Repair Kit, Tear-Aid, and the Sevylor Repair Patch. Make sure that the patch kit works on plastic or vinyl. You don’t want any air getting under your patch and ruining the glue, so let all the air out the mattress before continuing. If your hole is on the top side of the mattress you’ll need to remove the soft covering to make the patch stick. Take a wire brush or some sandpaper and lightly remove the felt coating until you only have plastic surrounding your leak. Some mattress makers refer to this soft coating as “flocking.” Using soapy water or a little isopropyl alcohol, clean off the leaky area so that there is no dust, dirt, or debris surrounding the hole. Dry it completely before continuing. You want ample room to cover the leak, so cut your patch so it fits over the hole with a centimeter or more of the patch around every side. If your patches are pre-cut, use one that offers 1-2 centimeters of space around the hole itself. All patches function in one of two ways: they are simply applied like stickers, or you must apply special glue and then attach the patch. Either way, follow the instructions and apply your patch smoothly. Don’t remove it to get it “perfect.” As long as it covers the leak entirely it will work, and taking it off and reapplying it will make it less sticky. Once your patch is on, apply pressure to it for 30 seconds or more to make sure it is firmly attached. Use the heel of your hand to press down on the patch, or use a rolling pin to strongly flatten the patch against the mattress. It can help to lay a heavy, flat object on top of the patch to keep the pressure on it. Do not try to inflate your mattress until the...
