• Low VOC: Meets the less than 250 g/L VOC content requirement of the OTC Model Rule and carries a LEED listing.
• PS Cover Strip Prep: Applied over PVC Step 1 Activator to prepare KEE HP and PVC membrane for Pressure-Sensitive Cover Strip.
• Easy Application: Apply with a paintbrush or medium-nap paint roller; no mixing or thinning required.
• Olive Drab Color: Non-white color shows coverage; limit exposure beyond the cover strip area for aesthetics.
• Proven Coverage: Coverage rates as high as 700 sq ft per gallon can be expected.

Specifications Table:

Coverage & How Much You Need:

One gallon covers up to about 700 sq ft of splice area when applied uniformly with no streaking or puddling. Apply to a wider area than the actual splice to ensure complete coverage.

Fit and Compatibility:

Use on Sure-Flex KEE HP and PVC membranes that have already received Low-VOC PVC Step 1 Activator, then install Carlisle PVC Pressure-Sensitive Cover Strip while the primer is still tacky. Sold separately: Step 1 Activator and PS Cover Strip.

Frequently Asked Questions (FAQ):

Q: What is included in one order?
A: One can of Low-VOC PVC Step 2 Primer (manufacturer packaging is two 1-gallon cans per carton).

Q: How much area does one gallon cover?
A: Coverage rates as high as 700 square feet per gallon can be expected; rates vary with substrate and conditions.

Q: Do I need to mix or thin it?
A: No. Mixing is not recommended even when settling occurs, and thinning will affect performance; use full strength.

Q: What does it pair with?
A: It follows Low-VOC PVC Step 1 Activator on KEE HP or PVC membrane and prepares the surface for PVC Pressure-Sensitive Cover Strip.

Q: Can it over-dry?
A: Yes. Do not let it over-dry or lose tack; install the cover strip immediately after flash-off while it is still tacky.

Q: How should it be stored?
A: Store at 60F to 80F, protect from moisture, and use opened containers within 48 hours.

Expert Verdict Reviewed by the SuperArbor Pro Desk

This primer is a required intermediate step for PS cover strip adhesion on KEE HP and PVC membranes; skipping Step 1 or letting Step 2 over-dry is a common cause of splice failures. Work in good ventilation, keep it away from heat and sparks (flash point 40F), and avoid condensation when ambient temperature is near the dew point. The olive drab color is not white, so keep primer within the cover strip footprint for appearance.

Flammable, harmful if swallowed and irritating to skin and eyes: wear ANSI/ISEA 105-2005 permeation-resistant gloves and safety glasses, keep away from heat, flame and sparks, and never smoke while using.
