These poly patches are the perfect remedy for small tears or damage from rodents, branches or other causes to your winter pool cover. The patch’s adhesive backing makes it easy to use and quick to put on. To use, clean and dry the area around the hole first, remove the back of the patch and press the patch into place. For more significant tears, place another patch on the opposite side of the winter cover so the patches mirror each other. Each kit includes two 8-1/4 inch by 10 inch patches that can be cut to shape and size.
