PG 500 Modified Cement

Brand: Polyglass, Inc

PG 500 is a high quality formulation suitable for use as a cold-applied bonding agent for SBS roofing systems as well as various other membrane systems. 

PG 500 has a heavy, “trowel-grade” consistency which makes it ideal for flashing details, attachment of membrane to steep slopes and parapet walls and a variety of waterproofing repairs. Its flexibility and elasticity make it superior to standard plastic cements especially where there are moving joints.
Features
  • High flexibility to accommodate temperature-related expansion and contraction of the roof system
  • Great bonding strength
  • Provides exceptional weathering characteristics over a wide range of challenging temperatures and weather conditions. Will not mudcrack and will remain highly flexible, resilient and durable through all seasons
  • Eliminates the need for kettles and torches
  • Interlocking fiber matrix assures uniform, excellent adhesion
  • When used on a vertical surface at high temperatures, exhibits excellent flow resistance
  • Non-destructive to asphalt based roofing membranes
  • Asbestos free – 100% recycled cellulose fibers
