    Product Description

    Basic Use

    WEATHERMATE™ Straight Flashing is a self adhering flexible flashing used as part of a water-resistive barrier system on typical building substrates such as; wood, insulating sheathing, house wrap, and concrete. It is used to prevent water from entering the wall at windows, doors and other penetrations through the wall. WEATHERMATE™ Straight flashing is also used to create a seal between the foundation and framing.

    Limitations

    Minimum application temperature: 40°F (4.4°C). WEATHERMATE™ Straight Flashing may be left exposed to sunlight up to 180 days.

    Installation (Preparation)

    For best adhesion performance, apply WEATHERMATE™ Straight Flashing at air and surface temperatures of 40°F (4.4°C) or above. A spray adhesive such as 3M High Strength 90 is recommended if applying WEATHERMATE™ Straight Flashing directly to OSB, concrete or other surfaces where additional adhesion may be required. Follow spray adhesive manufacturer’s recommendations for application temperature and dry time.

    Prepare substrate surface as necessary to ensure it is clean, dry and free of frost, dirt, dust, grease/oil, debris and other contaminates that may interfere with adhesion. Remove any loose or damaged areas along with nails, sharp protrusions or any other conditions that may affect a smooth flat adhesive bond to the substrate.

    Application

    Cut flashing strips into easily handled lengths. Peel white plastic release film from the adhesive, position against substrate and without wrinkling or stretching, press firmly into place with a smoothing tool. It is important to apply pressure to ensure strong long term bond to the substrate. Do not stretch flashing or force changes in the directional line of application as this can cause wrinkling and channels that prevent a smooth tight seal to the substrate. Once an adhesive bond has been established, it may be difficult to reposition the flashing without affecting sealing and adhesion capabilities.
