Repairing a tear in your pond liner can be accomplished with some basic materials and careful steps. Begin by draining the pond to expose the damaged area, then clean it thoroughly, removing all dirt, debris and algae around the tear. If the tear is small, a patch can be applied using a suitable liner repair kit, which typically includes a waterproof adhesive and patch material made from the same type of liner.
Cut a patch that is larger than the damaged area. It should extend at least two inches beyond the tear on all sides to eliminate the possibility of leaks. Apply the adhesive to both the patch and the liner around the tear, then firmly press the patch into place, smoothing out any air bubbles. For larger tears, you may need to use a combination of patches and adhesive, ensuring a secure bond. Allow the adhesive to cure according to the manufacturer’s instructions before refilling the pond.
