    • Patented acrylic latex sprayable formulation
    • Designed for use around the rough opening of windows and doors and over window flanges
    • Seals around nails and forms a tight, seamless barrier against unwanted water and air leakage
    • Spray applied with an airless paint sprayer
    • Can also be brushed or rolled, for greater application flexibility
    • Available in 5-gallon pails
    • For interior and exterior use
    • Solvent free
    • Low VOC and nonhazardous
    • Easy water cleanup
    • Provides full coverage for up to 1/4" gaps or similar


    Flashing adheres to most building surfaces:

    • Plywood and OSB sheathing and framing
    • Foam panels: XPS insulation
    • Housewrap, masonry, tile and concrete substrates
    • Vinyl window flange
    • Other sealants: acrylic caulks, polyurethane foam and silicone

    DOW LIQUIDARMOR Flashing and Sealant is a sprayable, waterborne coating to be used around the rough openings of windows and doors and over window flanges on residential homes that delivers better performance, higher reliability, easier application and lower installation cost than incumbent products (i.e., butyl flashing tapes or plastic sill pans).

    If an airless paint sprayer is not available, the coating can be brushed or rolled, etc. The sprayable formulation is also engineered to penetrate and seal hard-to-reach gaps.

    DOW LIQUIDARMOR Flashing and Sealant dries to form a tight, seamless barrier around the window. It self-seals around nails, forming a tight, seamless barrier against water and air leakage.

    DOW LIQUIDARMOR Flashing and Sealant offers exceptional adhesion to oriented strand board (OSB), plywood, extruded polystyrene (XPS), housewrap, GREAT STUFF PRO Window & Door Insulating Foam Sealant,* and acrylic caulk, among other substrates. Once cured, it is extremely durable, withstanding jobsite conditions and weathering when applied around the rough opening of a window or over the top of the nail flange of windows.

    Surface and ambient temperatures should be 35°F and rising and below 120°F during application. DOW LIQUIDARMOR Flashing and Sealant tolerates rain shortly after installation. However, do not apply to surfaces with standing water or frost.


    General Characteristics

    LIQUIDARMOR can be brush or spray applied. As long as 50 wet mil (thicknessof a dime) is laid down on the surface in question, the final cured property isnot affected. Short, coarse haired paint brush (chip brush) works best in ourexperience because you can load more of a thick, viscous liquid to apply athick enough deposit to be close to 50 wet mils in one stroke.

    Surface coverage per pail depends on how wide and thick you apply. Thecoverage in linear feet by application width is in the table below for yourreference:
