BB LF Off Spec

(Formerly Blue Barrier Liquid Flashing 2100)


Polyguard Blue Barrier Liquid Flashing (BB LF) is an all-purpose, fluid-applied flashing installed with an application gun and trowel that is used to create a weather-resistant, fully adhered air barrier system around window and door installations. It was developed utilizing Silyl Terminated Polyether Technology (STPE). It comes in a 20oz “sausage tube” requiring a “sausage gun” to apply. Can be left exposed to UV light for up to 9 months.

*This off-spec BB LF product is still good, but due to curing at the seam, it will only yield about 75% of the normal product. 
ALL SALES FINAL. NO RETURNS.

Please note the pricing is per tube. Case contains 12, 20 oz sausages of BB LF Off Spec product. Add 12 to cart to receive a full case.
