The Seal That Makes It Waterproof
Strong. Flexible. Guaranteed to Last.
When it comes to waterproofing your shower, every joint matters. That’s why the HYDRO-BLOK Joint Sealant was developed as the only approved sealant and adhesive for use with all HYDRO-BLOK shower system components.
Engineered for Precision & Performance
Formulated with a low-VOC polyurethane blend, HYDRO-BLOK Joint Sealant delivers a strong, flexible, and watertight seal that moves naturally with your system — preventing cracks, leaks, and failures over time.
It’s easy to apply, cures quickly, and provides long-term adhesion for all HYDRO-BLOK panels, pans, curbs, and accessories.
