GoBoard® Corner is a pre-formed waterproofing component designed to seal inside and outside 90° corners in tile showers, steam rooms, and other wet-area installations. It integrates directly with the GoBoard® 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.
Key Features
- Pre-Formed Corner Geometry: Fits inside and outside 90° corners without folding or cutting membrane material.
- Wet-Area Waterproofing Support: Designed for use in showers, steam rooms, and other moisture-exposed assemblies.
- Thin-Set Compatibility: Works with both modified and unmodified thin-set mortars.
- Simplified Installation: Reduces corner preparation steps while maintaining consistent waterproof coverage.
- Standards Compliance: Meets ANSI A118.10 and exceeds ASTM E96 and ASTM C627 “Extra Heavy” requirements.
