Expert Verdict — Reviewed by the SuperArbor Pro Desk
Prime abraded, clean concrete and masonry before applying JM SP Liquid Flashing details; adhesion on dense or smooth masonry depends heavily on surface preparation. The quick-curing formula helps crews complete flashing details in a single mobilization. At 0.25 gal per pack, order enough packs for the total linear footage of flashing detail work before starting.
Read and follow the safety data sheet, wear appropriate PPE, and ensure adequate ventilation when applying primers on the roof.
