Each Tear-Aid repair patch is made from an exceptionally tough, matte finish, abrasion resistant, elastomer that resists puncture and tearing. The Tear-Aid type B patch is made specifically for patching vinyl and it is combined with an aggressive adhesive formulated for high bond strength. Tear-Aid vinyl patches won't discolor or pull off when stretched. They work great for large or small tears and very easy to use. Clean repair area thoroughly, cut patch larger than the repair area, remove paper backing, place patch over hole, and then press down firmly. Wait 30 minutes until you inflate and you're ready!
