(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 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.
