McGuire FlexGuard T-Joint Patch - McGuire Roofing Products

Each T-Joint Patch is a perfect 4.5” diameter premolded circle.
Provides substantial labor savings compared to field fabricating.
Seals channels at splice intersections created by seam step-offs.
More consistent appearance and installation compared to field fabricated patches.

Clean the surface to be welded with Weathered Membrane Cleaner.
Use a lower temperature setting on the hand heat welder than that used for welding reinforced TPO membrane. (Typically, a setting of “6” on a scale of “10” is appropriate for welding TPO T-Joint Patches.)
Center the T-Joint Patch over the splice intersection, begin welding at the center point and work towards the outside. Use the edge of the roller to crease the T-Joint patch into membrane step-offs to achieve a proper seal.
Using a probe, check all splices for voids and cold welds only once the T-Joint Cover has completely cooled. Make any needed repairs.
