DuraLiner™ EPDM Liner Primer – 1 quart
Essential Surface Preparation for Professional Liner Seaming
Achieve professional, watertight liner seams with DuraLiner™ EPDM Liner Primer, the essential first step in proper liner seaming and repair. This specialized primer cleans and prepares EPDM rubber liner surfaces, removing contaminants, oils, and residues that interfere with tape adhesion, ensuring your seam tapes bond securely for long-lasting, leak-free performance.
Proper surface preparation is the foundation of successful liner seaming. Without primer, tapes may appear to adhere initially but can fail over time as contaminants prevent proper bonding.
Two Formulas Available
Standard EPDM Liner Primer (DEP32) – The original formula for maximum cleaning and prep performance. Ideal for most applications where VOC regulations don't apply.
Low VOC EPDM Liner Primer (DEP32LV) – Specially formulated to meet strict VOC regulations. Required for use in CA, CT, DC, DE, MA, MD, ME, NH, NJ, NY, PA, RI, VA, and VT. Provides the same excellent surface preparation while meeting environmental regulations.
Key Features
- Essential surface preparation for EPDM liner seaming and repairs
- Removes contaminants, oils, and residues
- Dramatically improves tape adhesion
- Available in standard and low VOC formulas
- 1 quart covers approximately 25 linear feet of seaming
- Use with scrubber pads (part #DL69P) for best results
- Quick flash-off time before tape application
Pro Tips
Always Use Primer: EPDM liner panels must be clean and dry for proper tape adhesion. Always use DuraLiner™ EPDM Primer to clean the material before applying tape.
Application: Use scrubber pads (part #DL69P) to apply the primer. Let dry to the touch (flash off) before applying tape.
Coverage: Approximately 25 linear feet of seaming per quart.
Regional Requirements: Certain states require Low VOC primer (DEP32LV). Standard primer may not be sold or shipped to CA, CT, DC, DE, MA, MD, ME, NH, NJ, NY, PA, RI, VA, or VT.
Frequently Asked Questions
Which primer formula should I choose?
If you're in CA, CT, DC, DE, MA, MD, ME, NH, NJ, NY, PA, RI, VA, or VT, you must use the Low VOC formula (DEP32LV). For all other states, either formula works.
Why is primer necessary for liner seaming?
Primer removes contaminants, oils, and residues that prevent proper tape adhesion. Without primer, tapes may fail over time, leading to leaks.
How much primer do I need?
One quart covers approximately 25 linear feet of seaming. Measure your seam length and purchase accordingly.
How do I apply the primer?
Use scrubber pads (part #DL69P) to apply the primer, scrubbing the liner surface to remove contaminants. Allow the primer to dry to the touch (flash off) before applying tapes.
How long does it take to dry?
Flash-off time typically takes 5-15 minutes depending on temperature and humidity. The surface should be dry to the touch before applying tapes.
Can I use this on old liner?
Yes, primer is especially important on used liner that has accumulated dirt, algae, and organic matter. Thorough cleaning with primer is essential for successful repairs.
Do I need scrubber pads?
Yes, scrubber pads (part #DL69P) are highly recommended. The scrubbing action helps remove contaminants and work the primer into the liner surface.
Can I apply tape immediately after priming?
No, allow the primer to flash off (dry to the touch) before applying tapes to ensure optimal adhesion.
