Benjamin Obdyke’s new HydroFlash LA. liquid-applied flashing simplifies the process of flashing rough openings, transitions and seams, as well as filling imperfections, penetrations, and geometrically difficult areas.
Sold in 20-oz. tubes, it applies with a caulk gun and is spread to a recommended 20- to 40-mil thickness, easily conforming around corners, arch tops, and awkward areas that normally require extensive cutting and bending to flash with tape. It also can be used to fill or cover gaps of less than 1/4”, or 1/4” to 1” with a backer rod.
