Wash and blow out saw cuts with compressed air (such as the BD Loops Air Wand) to remove dust, debris and standing water. It is recommended that ambient temperatures at the time of sealant application should not exceed 100F (38C) nor fall below 36F (2C). Do not apply to wet or icy surfaces. Curing time will be lengthened below 36F (2C) and shorted above 100F (38C).

Cut the tip of the Loop Goop cartridge using a safe tool. Tightly screw the disposable threaded nozzle in place and insert the cartridge into the caulking gun. Apply sealant from the bottom of the saw cut to within 1/8 (3.12 mm) of the roadway surface. Pneumatic and battery powered dispensing guns are available.

Will skin over in approximately 3 hours at 77F (25C) and 50% R.H. Hotter, more humid weather speeds up curing; cooler, dryer weather slows it down. Full cure will take several days, however traffic is permitted immediately after application.

For product handling and clean-up wear disposable latex gloves, rubbing alcohol helps clean up spills. If you are unsure if rubbing alcohol can be used on a surface/finish, first test clean a small inconspicuous area to see if damage occurs.

For maximum shelf life, store in a dry, cool place.
