BD Loop Shield is ready to use and requires no mixing or additives. Before sealant application remove dust, debris, and standing water. Suggested ambient temperature range for sealant application: 32°F – 120°F (0°C -48°C).

Application: Carefully cut the tip off the cartridge just above the nozzle threads. Thread sealant tip onto cartridge and place into quart sized caulking gun. Sealant should be applied from the bottom of the saw-cut groove. Slightly underfill the groove to be within 1/8” (3.12 mm) of the surface to prevent vehicles from tracking sealant. For easier application, pneumatic and battery powered dispensing guns are available.

Curing: BD-LS will skin over in approximately 45 minutes at 70°F (21°C) and 50% relative humidity. Temperatures below 32°F (0°C) and/or low humidity will slow skin/cure time. Strength will start to develop immediately and continue increasing for 7 days after application. However, if groove is slightly underfilled traffic is permitted immediately after application.

Storage: For Maximum shelf life store in a dry, cool, and well-ventilated place. Open cartridges can be saved for some time by capping the nozzle.

Spills/Clean Up: Wet BD-LS can be cleaned with alcohol. Dry BD-LS can be removed by abrading or scaping

Coverage Per Tube/Case

It is always better to purchase 1 extra tube of BD-LS than to run out of Loop Shield on a jobsite and have to run back to your distributor.

Using a 3/16″ wide blade over 1/4″ blades will save you 25% in loop sealant.
