Use and Care Manual

Glass Membrane for Reinforcement or Repair of Roof
Membranes and Flashings
TremPro Glass Mesh Reinforcing Fabric is a non-shrinking, non-rotting, vinyl coated, woven glass mesh. The
glass filaments are firmly bonded together to prevent strands from unraveling during application.
TremPro Glass Mesh Reinforcing Fabric provides excellent tensile strength for reinforcing flashing seams,
membrane laps, or other roof system details. TremPro Glass Mesh Reinforcing Fabric can conform to
irregular surfaces because of its high degree of flexibility. The open weave design of TremPro Glass Mesh
Reinforcing Fabric facilitates quick and uniform embedment in mastics and asphalt based products, Tremco
asphalt or tar based mastics or asphalt emulsions.

Width: 6" (152 mm)

Surface Preparation: Surface must be clean and properly prepped per instructions on mastic or
asphalt based product being used with TremPro Glass Mesh Reinforcing Fabric. Cut TremPro Glass
Mesh Reinforcing Fabric to appropriate size. Apply a full coverage of the specified roofing mastic
or adhesive. Set TremPro Glass Mesh Reinforcing Fabric into the freshly applied material and apply
pressure with a brush or trowel to assure complete adhesion. If specified, apply additional courses
of TremPro Glass Mesh Reinforcing Fabric and mastic / adhesive. Apply a top course of mastic in a
full coverage to completely cover the TremPro Glass Mesh Reinforcing Fabric.
NOTE: When repairing blisters which have been cut open, or when sealing splits which extend
through built-up roof membrane, use two plies of TremPro Glass Mesh Reinforcing Fabric
embedded between applications of Tremco mastics.
