® LF Liquid-Applied Flashing
Air-Bloc
or pigments.
Fill open joints, seams and cracks wi der than 1/8” (3 mm) up to ½” (13 mm) with 925 BES Sealant or Air-Bloc LF prior to final application of Air-Bloc LF .
Apply : Apply Air-Bloc LF to substrate in a serpentine fashion using appropriate caulking gun and then spread using a trowel, joint knife or roller to achieve a monolithic membrane over the rough opening surfaces. Regularly monitor wet mil thickness during application to assure adequate coverage. Air-Bloc LF can be applied in a single coat. Spread uncured Air-Bloc LF to cover the inside of the rough opening and extend a minimum of 4” (100 mm) over the surface of the exterior wall. If a continuous air barrier such as Air-Bloc ® or Blueskin ® air barriers are used over the exterior wall, overlap Air- Bloc LF a minimum o f 2” (50 mm) over adjacent membranes.
Coverage Rates : Apply per published architectural specifications. Typical application rates include: • Smooth Surfaces such as exterior gypsum sheathing or formed concrete: 10 ft 2 (0.9 m 2
) per 20 oz (0.6 L) sausage to give
a wet film thickness of 25 mils (0.6 mm)
Rough Surfaces such as CMU: 6 ft 2
2 ) per 20 oz (0.6 L) sausage to give a wet film thickness of 40 mils (1 mm)

The above reference chart is based on theoretical coverage calculations for a smooth surface. Rough surfaces can reduce coverage rates significantly depending on texture and porosity of surface.
Limitations : Air-Bloc LF can be exposed for up to 6 months but is not designed for permanent exposure to ultra-violet light and should be covered as soon as practical after application. Application at temperatures below 40 F (4 C) will slow curing. In low humidity conditions, curing may be aided by lightly misting Air-Bloc LF with water.
Many silicone sealants show excellent adhesion to Air-Bloc LF . Contact the sealant manufacturer for more information.
