About MATRIX™ 202 SBS Flashing Cement

This heavy, “trowel-grade” consistency cement makes it the ideal product for flashing details, attachment of membrane to steep slopes and parapet walls, and a variety of waterproofing repairs, especially at moving joints where its flexibility and elasticity make it superior to standard plastic cements. Its superior-bonding strength and high flexibility accommodate temperature-related expansion and contraction of the roof or waterproofing system with a smooth, flexible application – even at low temperatures.  

  • Repairing splits, breaks, and holes in roofing and flashing
  • Along joints of metal roof panels, metal edging, gutters, coping caps, and air-conditioning ducts
  • At pipes and projections through below-grade damp proofing membranes, for sealing shingles, and repairing asphalt built-up, metal, and masonry roofs
