Using the Tenacious Tape Neoprene Patch is easy. First, measure the rip, hole, or area you want to reinforce and cut the patch to the appropriate size. Then, place the patch over the damaged area on your neoprene item. Set your household iron to a medium - high heat and apply it gently over the patch for a few seconds at a time, moving the iron around to ensure even adhesion. Be careful not to overheat the iron as it might damage the neoprene. After the repair, avoid getting the patched area wet for a few hours to let the adhesive set properly. To maintain your neoprene gear with the patches, wash it gently by hand in cold water with mild detergent. Don't wring or twist the item, and let it air dry away from direct sunlight. This will help keep the patches and the neoprene in good condition for a long time.
