Expert Verdict — Reviewed by the SuperArbor Pro Desk
Flashing-grade polyurethanes like H.E.R. 202 are chosen when you want a self-flashing, fabric-less seal at details such as penetrations and curbs. Apply to clean, dry, primed-compatible substrates and tool the bead fully for adhesion. Keep joint design within the sealant's movement capability, and consult the manufacturer's data sheet for priming requirements on specific membranes.
Polyurethane sealants contain reactive chemicals; wear gloves and eye protection, work in ventilation, and follow the safety directions on the tube.
