Professional Double-Sided Tape for Durable Liner Seams

Create strong, watertight liner seams with DuraLiner™ Double Sided Liner Seam Tape, the foundation of professional EPDM liner seaming. This high-performance tape features adhesive on both sides to join liner panels together, creating the primary bond in a complete seaming system that delivers leak-free performance for years.

Designed specifically for EPDM rubber pond liners, this 3" wide double-sided tape provides the critical first layer in the proven two-tape seaming method. When combined with DuraLiner™ 6" Single Sided Cover Tape, it creates professional-grade seams that are as strong and reliable as the liner itself.

Pro Tips for Best Results

Always use DuraLiner™ Primer (part #DEP128 or DEP32) to clean and prep the liner before applying seam and cover tapes. Primer helps tapes adhere much better.

Use with Cover Tape: Apply this 3" double-sided tape to join liner edges, then cover with DuraLiner™ 6" Single Sided Cover Tape for a complete, leak-proof seam.

Use a Seam Roller (part #DLSR) after tapes are applied to work out air bubbles and ensure a watertight seam.


Frequently Asked Questions

What's the difference between the 25-foot and 100-foot rolls?

The 25-foot roll is ideal for smaller ponds or repairs, while the 100-foot roll is better for larger ponds or commercial installations. Both are 3" wide.

Do I need cover tape too, or just this double-sided tape?

You need both. Use this 3" double-sided tape to join liner edges, then apply DuraLiner™ 6" Single Sided Cover Tape over the seam to seal and protect it.

Why do I need to use primer?

DuraLiner™ Primer cleans and preps the liner surface, removing contaminants that interfere with tape adhesion. Using primer ensures the tapes bond securely for watertight, long-lasting seams.

What is a seam roller and do I need one?

A seam roller (part #DLSR) applies even pressure to work out air bubbles and ensure complete contact between tape and liner. It's highly recommended for creating truly watertight seams.

Can I use this tape for liner repairs?

Yes, this double-sided tape can be used as part of liner repair systems when combined with appropriate cover tape. Always clean and prep with primer first.

How wide is this tape?

The double-sided seam tape is 3" wide, designed to work with 6" single-sided cover tape that overlaps on both sides for complete seam protection.

Will this work with any EPDM liner?

Yes, DuraLiner™ tapes are designed to work with EPDM rubber pond liners. For best results, use the complete DuraLiner™ seaming system including primer and seam roller.

Can I apply this tape underwater?

No, surfaces must be clean and dry for proper adhesion. Drain the area, clean and prep with primer, apply the tapes, and allow them to bond before refilling.
