The Most Versatile Liquid Sealant!

"This is a fantastic product. By far the easiest way to flash a window or door opening and get a 100% air and water-tight seal. Also very helpful for sealing any difficult penetrations through your wall sheathing. Takes the place of flashing tape.- Mason Collins

Why Buy Our Liquid Flashing Sealant?

✅EFFECTIVE: Liquid Flashing Sealant will provide an air and water-tight seal for your home or building. It bonds to most building materials such as concrete, wood, and architectural metal. It can even bond to dry or damp surfaces which will help you apply it on irregularly shaped surfaces or shapes.

✅DURABLE: Because of the silicone and urethane combination and STPE technology, this liquid flashing sealant can withstand up to 180 days of extreme weather and UV exposure. It is not recommended you go over this duration as the product will start to lose its effectiveness. This product is compatible with most urethane, silicone, and acrylic sealants.

✅EASY APPLICATION: Ensure the panels are free of any dirt, debris, or oily films. Apply the Liquid Flashing Sealant into the joint and ½” on either side of it then using a spreader, spread the liquid sealant onto it until you can no longer see the material you’re sealing beneath.
