Hi Leanne, yes, the TigerClaw Install Gun will work with MoistureShield decking. According to the manufacturer, TigerClaw's TC-G fasteners are compatible with MoistureShield decking. The TC-G fasteners work with grooved deck boards. If your boards are not grooved, be sure to use the [TC-G Groove Cutter](https://www.diyhomecenter.com/tigerclaw-tc-g-slot-cutter-for-ungrooved-1-inch-or-thicker-decking).
