PONDGARD-POND-LINER-SEAMING-SUPPLIES
Double sided seam tape is used between 2 pieces of liner to seam together. For a long lasting seam you will want to prep the area first with tape primer and after you have applied the seam tape you will want to lay the single sided cover tape over that. As a final precaution you will want to lay a bead of lap sealant on both edges of the cover tape. Works on EPDM, Xavan, PVC, Poly and HDPE.
