Benjamin Obdyke has introduced HydroTape DS, an acrylic-based double-sided sealing tape for use with mechanically fastened housewrap that helps eliminate many of the issues and failure points of conventional seam tapes.
The 3/4” tape installs between the housewrap layers, adhering to the undersides of each layer where they overlap to help prevent blow-off during installation without interrupting moisture drainage or capturing bulk water. The tape’s acrylic adhesive is vapor permeable, ensuring any trapped moisture dries to the exterior. The adhesive also seals around fasteners to reduce air infiltration at penetration points.
Offered in 82-ft. rolls, HydroTape DS is split wound and has a release liner to ease application; the installer simply unwinds the tape onto the bottom housewrap layer, removes the release liner, overlaps the top housewrap layer, and applies pressure to create a strong seal.
