Expert Verdict — Reviewed by the SuperArbor Pro Desk
Trowel-grade SBS modified flashing cement is the go-to choice for vertical flashing work in hot climates because it holds its profile without sagging. Apply it into a sound, clean substrate and embed reinforcement fabric in the wet cement for seam and split repairs. Keep pails sealed between uses and size the pail to the job since large pails can skin over once opened.
Contains solvents; apply with gloves and eye protection in a ventilated area and keep away from open flames and ignition sources per the safety data sheet.
