Lucas Mod-Bit Adhesive #734 - Brush - Full Range

Lucas #734 is designed as a cold process inter-ply adhesive for SBS modified bitumen single-ply membranes. Cold process adhesives eliminate the need for hazardous torches and hot asphalt kettles. Lucas Modified Bitumen Adhesives are easy to apply with minimal equipment, effort, and cost. #734 may also be used to adhere polyisocyanurate, perlite and wood fiber insulation and fiberglass and organic base sheets.

Lucas #734 Mod-Bit Adhesive is manufactured from refined polymer modified asphalts, a special solvent blend, and nonasbestos reinforcing fibers. #734 is formulated to spread easily and evenly at the recommended rate of application.

Application:

Lucas Mod-Bit Adhesive should only be applied to surfaces that are sound, clean, and dry. Temperatures should be a minimum of 40° F and there should be no threat of rain. The adhesive may thicken in cold weather. To improve cold weather applicability, store the adhesives in a warm place prior to use. Apply directly from the can; do not thin. The SBS modified bitumen sheets should preferably be cut into sections less than 20 ft. in length and allowed to relax and flatten out before being installed. All laps should be a minimum of 4 inches wide. All laps should be rolled with a weighted roller and end laps should be weighted to insure a proper bond. A bead of adhesive should be evident at all seams. The adhesive may be left open for a short time before the modified roll is embedded to allow some of the solvent to evaporate and improve the initial bond.

Shelf Life: 2 years minimum.
