Tips for Purchasing/Using a Pond Liner ●Before purchase, you should measure the max length and width of your pond. It is better to order a liner that is slightly larger than the hole as you can cut it to any size. ●Also you can seam together multiple liners together to form a large pond liner. ●To better protect your liner from tears or punctures, please add a layer of underlayment before laying the liner in place. ●Pond underlayment alternatives: sand, newspaper, old carpet(plush side up), old liner, or any soft durable sheet of fabric. ●Allow the edge of the liner to overlap onto the ground. The liner can be secured with smooth /soft stones/objects (heavy or light) against liner only.
