AIR-SHIELD_™ LIQUID FLASHING
Liquid Flashing Membrane

DESCRIPTION
AIR-SHIELD LIQUID FLASHING is a high-quality, gun grade, low-odour, elastomeric, polyether, liquid-applied flashing and detailing membrane.  It bonds to most construction materials, such as aluminum, brick, concrete, wood, and vinyl and exterior gypsum board.

USES
AIR-SHIELD LIQUID FLASHING is to be used as a liquid-applied flashing, compatible with the entire line of AIR-SHIELD air, vapour, and liquid moisture barriers from W. R. MEADOWS.  This general-purpose, wet flashing membrane is used to seal rough openings and detail joints between exterior gypsum board.   AIR-SHIELD LIQUID FLASHING is designed for window and door flashing applications.   The product will not harm foam insulation.

APPLICATION
Surface Preparation … All surfaces to receive AIR-SHIELD LIQUID FLASHING should be clean, smooth, and free from all bond-breaking contaminants.  Product can be applied to damp surfaces if it is clean.   Remove any damaged structural wall components.  Any raw edges of exterior gypsum board may require adhesive.  For detailed instructions, view the AIR-SHIELD LIQUID FLASHING INSTALLATION GUIDELINES.

Application Method
Rough Opening … Inspect rough opening.  The rough or cut edge of gypsum board should be applied with adhesive.  Prefill any gaps with larger than 6.35 mm (¼”) with AIR-SHIELD LIQUID FLASHING and allow to skin over.

Apply bead of AIR-SHIELD LIQUID FLASHING in opening to be sealed.  Spread the material using putty knife across rough opening surface.  Next, apply a thick bead of material to the structural wall surface around rough opening.  Again, spread the material evenly using a putty knife.  Make sure material is spread in an even, monolithic manner.  Make sure to spread the material 12 – 15 mils (100 – 152 mm) on to structural wall.  Make sure material contains no pinholes and is void-free.  Again, make sure material is even, monolithic, and undamaged.

Make sure AIR-SHIELD LIQUID FLASHING covers the entire opening and seamlessly joins the specific AIR-SHIELD membrane being installed.  Allow surface to dry before installing windows, doors, wall assembly, and specific AIR-SHIELD membrane being applied.

AIR-SHIELD LIQUID FLASHING is also compatible with the entire line of AIR-SHIELD products for joint detailing in exterior sheathing panels.  For detailed application instructions, please view the AIR-SHIELD EXTERIOR SHEATHING PANELS INSTALLATION GUIDELINES.

Drying Time … At 21° C and 50% relative humidity, product skins within 30 minutes.  AIR-SHIELD LIQUID FLASHING is moisture curing. Low temperatures and low relative humidity slow dry time. High temperatures and high relative humidity accelerates dry time.

PRECAUTIONS
Not for use as a structural sealant. Not for use in place of AIR-SHIELD THRU-WALL FLASHING from W. R. MEADOWS.  Not for use below-grade or in locations designed to be continuously immersed in water.  When painting, use latex paints only.   Adhesion of membrane on oriented strand board (OSB) can sometimes be affected by the level of surface texture or the presence of wax that is part of the binder used to bond together the wood strands.  Adhesion of membrane to fire treated wood can sometimes be adversely affected by the treatment.  Prior to placement on OSB or treated wood, in-situ adhesion tests should be performed to determine suitability of substrate prior to full installation.  If there are variations in the OSB or fire-treated wood surface, multiple tests may be required.
