Using a Tear-Aid patch effectively involves proper surface preparation and careful application to ensure a strong, lasting bond on materials like fabrics or vinyl.
Applying a Tear-Aid patch typically follows a step-by-step process to repair tears or holes. A critical part of the application, especially when dealing with larger patches or tricky surfaces like the inside of a tent, is how you handle the protective liner.
Step-by-Step Tear-Aid Application
For best results, always refer to the specific instructions provided with your Tear-Aid kit, as there are different types (e.g., Type A and Type B) designed for different materials. However, the general application process often includes:
- Clean the Surface: Ensure the area around the tear or hole is completely clean and dry. Use an alcohol prep pad (often included in the kit) or rubbing alcohol. Allow the surface to dry thoroughly. This is perhaps the most critical step for achieving a strong bond.
- Prepare the Patch: Cut the Tear-Aid patch to the appropriate size, ensuring it extends at least one inch beyond the tear or hole in all directions. Rounding the corners can help prevent lifting.
- Peel and Apply Carefully: This is where technique is important. As indicated in the reference: "The first line of repair is patching the inside of the tent slowly. Peel back the liner leaving about half the paper liner on or the patch will stick to your hand carefully." This method allows you to position one part of the patch accurately before fully exposing the adhesive on the other half.
- Peel back only part of the liner (leaving some attached).
- Align the exposed adhesive over the tear, pressing down firmly from the center outwards to avoid trapping air bubbles.
- Once the first half is securely in place, slowly peel away the remaining liner while continuing to press the rest of the patch down onto the surface.
- Press Firmly: After the entire patch is applied, press down firmly over the entire area, working from the center outwards. Use a patch roller or even your fingernail or the edge of a credit card to apply pressure and ensure maximum contact between the adhesive and the material.
- Cure Time: While Tear-Aid provides instant adhesion, the bond strength increases over time. Allow the patch to cure according to the instructions (often 24 hours) before subjecting the repair to significant stress.
Practical Tips
- Always apply the patch to the inside surface first if possible, especially for items like tents or inflatables, as this surface is often under tension when in use.
- For larger tears, you may need patches on both the inside and outside surfaces for maximum strength.
- Ensure the patch material is compatible with the material you are repairing (Type A for canvas, rubber, nylon, plastics; Type B for vinyl and vinyl-coated materials). Using the wrong type will result in a poor bond.
Following these steps, including the technique of partially peeling the liner first, helps ensure a smooth, bubble-free application and a durable repair with a Tear-Aid patch.
