Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pourable two-part sealants like this are the standard fill for pitch pockets and penetration pockets where mastic would sag. Mix thoroughly in the stated ratio and pour in one pass so the material levels and cures uniformly. Check the JM data sheet for pot life and membrane compatibility, and detail the pocket flashing before pouring.
Wear gloves and eye protection when mixing and pouring two-part sealants, and follow the SDS for handling and ventilation precautions.
