Key Features
The "System" Glue: This sealant is the critical component of the HYDRO-BLOK water-tight warranty. It is specifically formulated to bond, seal, and waterproof all joints and seams between shower pans, wall panels, and accessories.
Superior Adhesion: Unlike standard silicone, this SMP formula creates a high-strength structural bond to the HYDRO-BLOK cement coating, as well as to PVC, ABS, and metal drain components.
User-Friendly Application: It is low-odor, VOC-compliant, and stays flexible after curing. It can be applied to damp surfaces and is even workable in temperatures as low as $30°F$ ($-1°C$).
Installation Coverage
-
Standard Shower (3x5): Typically requires 2 to 3 tubes for all wall seams and the pan-to-wall connection.
-
Large/Custom Showers: Plan for 1 tube for every 15–20 linear feet of joint.
-
Pro Tip: Use the provided HYDRO-BLOK putty knives to spread the sealant flat over the seams before applying the reinforcing mesh tape.
Applications
Primary Seal: For all pan-to-wall, wall-to-wall, and wall-to-ceiling joints.
Drain Connection: Essential for sealing the HYDRO-BLOK shower pan to the drain body.
Accessories: Used to glue and seal niches, benches, and curbs to the wall panels.
HYDRO-BLOK Joint Sealant is more than just a caulk; it is a structural adhesive and waterproofing membrane in a tube. For a leak-proof shower that stands the test of time, this sealant is the most vital tool in your installation kit.
