How to patch larger tears?

Cut a piece of repair material large enough to overlap the damaged area by approximately 2 inches and round off the edges. Using a fine brush, apply glue to the under side of the patch and around the area to be repaired. Only apply a thin layer, too much glue will often interfere with a proper repair Wait 10 minutes for glue to set. Then apply a second thin layer of glue to both the patch and the boat as well. Wait another 8 minutes for glue to set. Then apply a 3rd very thin layer of glue to the patch and the boat. Let sit for 5 minutes (don’t allow it to completely dry) and then firmly place patch on the damaged area. Apply patch so that all air bubbles will be forced out of the patch. Wait 10 minutes, and then inflate the chamber very slightly, just so the tube is lifted away from any other side of the tube, so it doesn’t get glued together. Use a weight to apply 3‐5 lbs. of pressure for 24 hours. After the patch has dried, apply glue around the edges for a complete seal (then let dry an additional 12 hours).
