HYDRO BAN is a single-component liquid polymer designed for waterproofing and crack isolation in both interior and exterior applications. The product forms a flexible, seamless barrier capable of bonding directly to various substrates without requiring fabric reinforcement in many instances. It is utilized in areas such as shower pans, pools, and foundations, offering a rapid waterproofing solution for wet environments. The membrane also incorporates Microban antimicrobial product protection to inhibit the growth of mold and mildew.
Product Description and Key Features
HYDRO BAN is characterized as a thin, load-bearing waterproofing/crack isolation membrane. Its formulation allows for a seamless application, eliminating the need for fabric in most field, cove, and corner applications. The product is a self-curing liquid rubber polymer, simplifying the installation process. A key feature is its ability to allow for flood testing within two hours at 70°F (21°C) or higher, accelerating project timelines.
The membrane’s thin profile, curing to a thickness of 0.020–0.030" (0.5–0.8 mm), minimizes build-up and maintains surface level. It exhibits a color change during the curing process, transitioning from a light sage to an olive green, providing a visual indication of proper application. HYDRO BAN is also non-flammable and exceeds ANSI A118.10 and A118.12 standards. It is IAPMO approved.
Applications and Substrate Compatibility
HYDRO BAN is suitable for waterproofing interior and exterior surfaces. Specific applications include shower pans and pool waterproofing, as well as foundation protection. The product bonds directly to a wide variety of substrates, including metal. However, it is specified for use with PVC and ABS plumbing fixtures only.
The membrane provides anti-fracture protection of up to 1/8" (3 mm) over shrinkage and other non-structural cracks, enhancing the durability of tiled surfaces. It is rated for “Extra Heavy Service” per TCNA performance levels, as defined by ASTM C627 Robinson Floor Test. Tile, brick, and stone can be installed directly onto the cured membrane.
Installation Considerations
The documentation indicates that HYDRO BAN does not require fabric for gaps of 1/8" (3 mm) or less, although complete instructions for such applications are detailed in document DS 663.5. Flood testing is permitted after a two-hour curing period at 70°F (21°C) or higher, but cautions regarding curing are referenced, suggesting specific conditions must be met for successful testing.
Product Specifications and Packaging
HYDRO BAN is available in several packaging options: 5-gallon (18.9 L) pails for commercial use (36 units per pallet) and 4 x 1-gallon (3.8 L) pails packed in a carton (30 cartons per pallet). Factory-sealed containers are guaranteed for two years when stored within a temperature range of >32˚F (0˚C) and <110˚F (43˚C).
The product does not list available colors or finishes beyond the color change observed during curing. It is part of the LATICRETE system and is currently available in Canada and the United States. The product incorporates a patent, though the patent number is not specified in the provided documentation.
Microban Antimicrobial Protection
HYDRO BAN is equipped with Microban antimicrobial product protection. This feature is designed to inhibit the growth of stain-causing mold and mildew on the waterproofing membrane, contributing to a more hygienic and durable installation. The documentation does not provide details on the specific mechanism or longevity of the Microban protection.
Performance Characteristics
The membrane exhibits rapid drying characteristics, facilitating a faster time to tile installation. Its load-bearing properties contribute to the overall structural integrity of the waterproofing system. The product’s flexibility allows it to accommodate minor substrate movement without compromising the waterproof barrier.
Safety and Handling
The provided documentation does not contain specific safety data sheets or detailed handling instructions. However, the product is described as non-flammable. Further safety information is available through separate Safety Data Sheets, referenced in the product overview.
Conclusion
LATICRETE HYDRO BAN is a single-component liquid polymer offering a comprehensive waterproofing and crack isolation solution for various applications. Its key benefits include rapid curing, ease of installation, and antimicrobial protection. The product’s ability to bond directly to multiple substrates and accommodate minor substrate movement makes it a versatile choice for both residential and commercial projects. Adherence to installation guidelines and proper storage conditions are essential for optimal performance.
