Expert Verdict — Reviewed by the SuperArbor Pro Desk
Two-part foamable cartridges are a efficient way to adhere polyiso and cover boards on tear-offs or recover projects where hot asphalt is impractical. Dispense beads per JM's current specification and detail drawings, and verify board type, deck condition and ambient temperature before starting. For very large areas, compare cartridge yield and bead spacing against full-size low-rise foam kits to pick the most economical format.
Follow the SDS and manufacturer instructions: wear gloves and eye protection, provide ventilation, and never point a dispensing gun at people since mixed polyurethane foam expands rapidly.
