Tear Mender - Fabric Adhesive Tear Mender is a natural and non-toxic liquid adhesive that bonds fabric upon contact. You can apply it like glue on a tear, or spread it on a fabric patch, and it bonds in minutes. Repaired fabrics stay flexible and soft even after washing. Great for dropped hem, a broken belt loop, or a run in the carpet. It also works on tears in the seat of your car, damaged sports gear, or rips in a tent. It’s waterproof and UV-resistant.
