Not for use with Carlisle Pressure-Sensitive products or on splice areas, and not compliant in certain California counties that require Low-VOC Bonding Adhesive 1168.
Frequently Asked Questions (FAQ):
Q: What is included?
A: One 5 gallon pail of yellow Low-VOC Bonding Adhesive; rollers and mixing equipment are sold separately.
Q: How much area does a pail cover?
A: Approximately 60 sq ft per gallon, so a 5 gallon pail covers up to about 300 sq ft of finished area; porous masonry requires two coats.
Q: How is it applied?
A: Stir to a uniform yellow color, then apply with a 9 in. medium nap roller to both substrate and membrane, allow solvents to flash off until it passes the tack test, then roll the membrane into place and broom for contact.
Q: Which membranes does it bond?
A: Carlisle EPDM and TPO membranes; do not use it with Pressure-Sensitive products or on splice areas.
Q: How should I store it?
A: Keep it between about 60 and 90 degrees F for application ease; it is flammable, and prolonged freezing will thicken it until it is restored to room temperature for at least 24 hours.
Q: Is it VOC compliant everywhere?
A: It meets the OTC Model Rule <250 gpl limit, but it does not comply with VOC regulations in certain California counties, which require the Low-VOC Bonding Adhesive 1168 instead.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Mix this adhesive thoroughly once per day until uniformly yellow with no dark streaks; an air-operated mixing paddle and warm storage help. Watch flash-off closely, especially in hot weather where it can occur in 5 minutes or less, and install the membrane only after it passes the tack test to avoid trapped-solvent blisters. For jobs in the restricted California counties, specify Carlisle Low-VOC Bonding Adhesive 1168 instead.
This adhesive is extremely flammable and solvent-laden: keep all ignition sources away, work with strong ventilation, ground containers during transfer, and review the Safety Data Sheet before use.
