Polyglass PG 400 is a trowel-grade, cold-applied plastic roof cement for sealing and repairing non-polymer modified roof membranes. Each sell unit is one 2.8 gallon container.

Key Features:
- Trowel-Grade Consistency: The trowel-grade formulation makes PG 400 well suited to flashing details and detailed waterproofing repairs.
- Will Not Separate: Polyglass engineered the formulation so the cement will not separate in the container.
- High Flexibility: The compound flexes to accommodate temperature-related expansion and contraction of the roof system.
- All-Season Weathering: It delivers exceptional weathering over a wide range of temperatures, will not mudcrack, and remains resilient and durable through all seasons.
- Interlocking Fiber Matrix: An interlocking fiber matrix assures uniform, excellent adhesion.
- Cold-Applied: PG 400 is applied cold, so no heating equipment is required for sealing and repair work.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Trowel-grade plastic cements like PG 400 are the workhorse choice for detailing flashing, sealing penetrations, and patching non-modified bitumen membranes on maintenance calls. Apply it cold with a trowel and work it well into joints so the interlocking fiber matrix bonds uniformly. For heavy moving joints, pair it with membrane reinforcement or fabric as the roof system manufacturer directs.
Wear gloves and eye protection when handling roof cement, and follow all roof-top work safety practices on the jobsite.
