Expert Verdict — Reviewed by the SuperArbor Pro Desk
PG-1 suits commercial re-roofs where mechanical fasteners would add penetrations, deck corrosion risk, or thermal bridging. Match container sizes (5 gal or 15 gal) for Part A and Part B and plan your adhesive rate per the membrane manufacturer's wind-uplift requirements. Its low-rise foam also tolerates minor substrate irregularities better than ribbon-applied single-component adhesives.
Two-component polyurethane adhesives require proper ventilation, gloves, and eye protection during mixing and dispensing; follow the safety data sheet.
Specify Millennium PG-1 Pump Grade Adhesive for solvent-free insulation and membrane attachment on your next commercial roof.
