NovaFlex MR150 is the sealant that goes under every screw-down snow guard we ship. It was formulated for metal roofing, not borrowed from a general construction line — neutral curing so it won't attack Kynar, Galvalume or galvanized panels, and flexible enough to move with the roof through a Canadian freeze-thaw cycle without shrinking, cracking or yellowing.

Sealant, not adhesive. MR150 seals the fastener penetrations and the guard base on screw-down installs. It is not rated to hold a snow guard on its own. For glue-down installs on standing seam, use SB-190 structural adhesive instead.
