AIM #610 Modified Bitumen Adhesive Trowel Grade is manufactured from renewed modified asphalts, a special solvent blend, and non-asbestos reinforcing bers. The special solvents contained in this product help to create an extremely strong and durable bond between the substrate and the modi ed bitumen membrane.

AIM #610 Modified Bitumen Adhesive Trowel Grade is designed for adhering SBS modified bitumen membranes to ashings and other vertical surfaces.

Although it was designed as an adhesive, AIM #610 Modified Bitumen Adhesive Trowel Grade can be used for ashing around vents, pipes, skylights, and other roof penetrations as well as for patching high movement areas on SBS and asphalt built-up roofs.

AIM #610 Modified Bitumen Adhesive Trowel Grade should only be applied to surfaces that are sound and clean. 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 unopened container 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 atten 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. This time period will vary significantly with weather conditions.

Equipment and foot traffic should not be permitted on the new roof until the adhesive has fully cured in order to prevent voids or blisters from forming at pressure points. AIM #610 Modified Bitumen Adhesive Trowel Grade should be applied evenly at a rate of 2 – 4 gallons per 100 sq. ft. (1/32 to 1/16 of an inch thick), depending upon the absorbency of the substrate. It may be applied with either pointed or notched trowel. Excessive rates of application may damage the membrane and prolong curing time.

Consult the modified bitumen manufacturer if more than one coat of adhesive is to be used in any roof system. Cure time will be between 24 and 48 hours. The strength of the adhesive will continue to increase beyond this initial bonding period.

Clean up with mineral spirits or waterless hand cleaner. Use care when handling solvents.
