GoBoardĀ® Corner is a pre-formed waterproofing component designed to seal inside and outside 90Ā° corners in tile showers, steam rooms, and other wet-area installations. It integrates directly with the GoBoardĀ® waterproofing system to support continuous moisture protection at corner transitions.
Constructed from a polypropylene non-woven fabric with an integrated waterproof membrane, the component installs using standard thin-set mortars and reduces preparation time compared to folded or cut membrane solutions.
