Expert Verdict — Reviewed by the SuperArbor Pro Desk
Mix Part A and Part B thoroughly with a low-speed drill before application; incomplete mixing is the most common cause of poor cure in 2-component polyurethanes. The non-sag consistency makes it well suited to vertical and overhead joints where self-leveling sealants would run. For deeper joints beyond 1/2 in., use backer rod to control sealant depth.
Follow the manufacturer's SDS and wear gloves and eye protection when mixing and handling 2-component polyurethane sealants.
