Using these Tenacious Tape Mesh Patches is a breeze. First, find the tear or hole in your mosquito net, bug screen, or tent mesh. Then, take one of the pre - cut 3' mesh patches from the pack. Position it carefully over the damaged area. Next, peel the Tenacious Tape ring and firmly stick the patch in place. That's it! Your repair is done in seconds. When using these patches, make sure the surface is clean and dry for better adhesion. Avoid using them on wet or dirty surfaces. For maintenance, there's not much to do. Just keep the remaining patches in a cool, dry place for future use. If you're using them outdoors, they can withstand normal weather conditions, but try to avoid excessive moisture for long - term durability.
