Product Specifications

Method	Description
Trowel	Flashing Bond is ready to use straight from the container. There is no settling or oil separation. In cold weather, store at room temperature to ensure workability. Flashing Bond should be applied to clean dry surfaces. Repairs - Trowel a base coat of Flashing Bond over the area to be repaired. Imbed a strip of Gar-Mesh into the base coat and top dress with Flashing Bond. The top coat should be sufficiently thick so that the weave in the membrane is completely covered (1 gal./7 linear ft. @ 8 in. wide x 1/4 in. deep). Flashing System - As part of a Garland flashing system, Flashing Bond is applied with a multi-ply flashing application beginning with a base ply of Garland two-ply base sheet and followed by one of Garland’s StressPly® family of smooth or mineral membranes as cap sheet. The result is a high performance, multi-ply, modified cold ap - plied flashing system. Apply Flashing Bond at a rate of 4-6 gal./100 sq. ft. (1.6- 2.4 l/m 2), per flashing ply with a 1/8” (3 mm) notched trowel. Bleed out at all overlap edges should be visible to ensure complete contact. The flashing should be mechanically secured at the end of each work day.

Features

Factory Formulation Ensures Uniform Quality

Flashing Bond is factory formulated under rigid quality control conditions to ensure uniform product quality. This eliminates the variables inherent on the job site preparation of roof materials where quality control depends on the individual roofer’s expertise.

Long-Lasting Performance

Flashing Bond is double-reinforced to outlast and outperform conventional roof cement. Long-strand fibers provide inherent reinforcement and eliminate run or sag in vertical surface applications. Flashing Bond should be used in conjunction with Gar-Mesh® as the reinforcing membrane for the roof repair, which will reinforce Flashing Bond as steel rods reinforce concrete.
