Aquascape EPDM Liner Cover Tape is used for seaming and repairing liner. When seaming EPDM liner, Aquascape recommends using an EPDM Cover Tape to ensure a proper seal. This 6-inch wide, one-sided adhesive tape provides the strength necessary to make a repair or seam that is sure to last. When making liner repairs and seaming multiple pieces of liner, it is important to seam the liner properly so that you do not run into any more issues down the line. We recommend using Firestone QuickPrime Primer for a proper seam Aquascape is passionate about the products we produce, providing unique products, designs, and features that stand above the competition.
