When your GORE-TEX gear gets a tear, patch it with Tenacious Tape GORE-TEX Fabric Patches. This kit contains two adhesive-backed fabric patches. The pressure-sensitive patches can be cut to the size and shape you need for a hole or tear in any gear. The strong patch bonds to the fabric and will not peel off even when washed. Apply low heat with an iron or tumble dry on low for increased adhesion. Use Tenacious Tape GORE-TEX Fabric Patches for a fast in-home or field fix to your GORE-TEX gear.

INSTRUCTIONS

3. Apply pressure from center out to eliminate air bubbles. The product can be used immediately. Adhesive will continue to strengthen over the next 12 to 24 hours.

Optional

4. After the patch has been applied, tumble the garment in a dryer for 30 minutes on regular setting or warm the patch with an iron.

5. Set an iron to medium or permanent-press heat. Use moderate pressure and circular motion for 30 seconds to heat evenly.
