Included with each SUP is a repair kit that includes glue and PVC patches. Once you have found the leak you will want to clean both the SUP and the patch being used to fix the leak. When ready, you will be applying 3 layers of glue. For the first layer, apply the glue on the area on SUP and the patch and spread it out thin using a brush or tool. Let it sit for 5 minutes, then repeat. Again let it sit for 5 minutes and repeat. Once glue has been applied 3 times, place the patch over the area on the SUP and smooth out for patch from the center to the edge of the patch to remove any air. Remove any excess glue and let the board sit for 48 hours.
