Building products manufacturer Benjamin Obdyke has expanded its line of flashing with the addition of a liquid-applied product that simplifies the process of preparing rough openings, transitions, and seams.
The company says the new product also is ideal for filling imperfections, penetrations, and geometrically difficult areas.
HydroFlash LA makes it easy to create a monolithic seal essential for protecting the home from moisture and air intrusion and avoid long-term performance issues, particularly around the window frame,” says Kaylen Handly, technical innovation manager for the company. “Benjamin Obdyke is always looking for the latest advancements to create cohesive building systems that result in resilient homes. HydroFlash LA is one more way to ensure those high performance levels around vulnerable, hard-to-flash areas such as window openings, HVAC and plumbing penetrations, outlet boxes, roof-to-wall intersections, and more.”
Founded in 1868, Benjamin Obdyke is known for manufacturing high-performance roof and wall products that improve the building envelope and the performance of other building materials in new construction and remodeling projects. The company says HydroFlash LA is part of the company’s mission to help builders create high-performance, systems-based building envelopes.

Sold in 20-ounce tubes, HydroFlash LA is a liquid-applied product that easily conforms to corners, curves, and awkward shapes, ensuring proper protection of openings against moisture and air intrusion. It easily conforms around corners, arch tops, and awkward areas that normally require extensive cutting and bending to flash with tape, the company says. It also can be used to fill or cover gaps of less than ¼ inch, or ¼ inch to 1 inch with a backer rod. The product applies with a caulk gun and should be spread to a recommended 20- to 40-millimeter thickness.
HydroFlash LA is vapor permeable and is suitable for most climates, including humid environments, such as Florida and colder regions like the Northeast, with an install temperature range of 25 to 100 degrees Fahrenheit. And unlike many flashing tapes, HydroFlash LA can be installed on damp or wet surfaces, so it is suitable for rainy climates such as the Pacific Northwest.
“The hybrid material, a silyl-terminated polyurethane, is extremely flexible and can stretch 300% of normal width while maintaining its adhesion,” the company says. “This ensures the flashing moves with the building over time and the seal stays intact. Flashing windows and other areas of the building envelope relies on installer application to be near perfect.”
HydroFlash LA is UV-resistant, paintable, and can be left exposed up to 180 days. It cures to a tack-free state suitable for window installation in about two to three hours and fully cures in 24 hours.
It’s compatible with all Benjamin Obdyke housewraps and is California Prop 65 compliant. For homes seeking Living Building Challenge certification, the flashing is free of Red List materials, the company says.
