LATICRETE Hydro BAN 1 Gallon – Easy-to-Apply Anti-Fracture Waterproofing Membrane

Overview

LATICRETE HYDRO BAN is a thin, load-bearing, single-component liquid rubber polymer that forms a flexible, seamless waterproofing membrane. Unlike systems that require fabric reinforcement, HYDRO BAN is designed to work as a crack isolation and waterproofing solution that bonds directly to a wide variety of substrates, helping to make tile installations more resilient.

Key benefits at a glance

• No fabric required for most gaps in the field, coves, or corners (1/8 in or 3 mm or less; refer to DS 663.5 for complete guidance)
• Single component and self-curing, forming a seamless, flexible membrane
• IAPMO approved for reliable performance and compliance
• Lighter color aids inspection and spot checking of the coating
• Non-flammable for safer handling on site

How it works and what it means for your project

HYDRO BAN pours on as a liquid, then cures to a durable, crack-bridging layer that resists water infiltration. Because it bonds directly to many substrates, it can simplify installation by reducing the need for fabric reinforcement in small gaps. The result is a seamless membrane that remains flexible to accommodate movement and stress.

In practice, the product supports fast project progress. You can take early advantage of flood testing in as little as 2 hours when conditions are right (70 F or 21 C, higher temperatures recommended). This potential helps you verify waterproofing before tiling proceeds, potentially saving time and avoiding rework later. The lighter shade of HYDRO BAN also makes defects easier to detect during inspection, which can contribute to a smoother install.

Installation notes and considerations

• Best results come with clean, sound substrates; avoid contamination and ensure proper surface preparation per guidelines
• For gaps up to 1/8 in (3 mm), fabric reinforcement isn't required; follow DS 663.5 for gaps near the limit
• Non-flammable, single-component, and ready for use without mixing

Whether you're waterproofing a shower pan, balcony, or other tile areas, HYDRO BAN offers a flexible, pragmatic approach to waterproofing and crack isolation, with a focus on straightforward application and inspection-friendly attributes. Consider it as a possible solution when you want a seamless membrane that bonds to substrates and supports quick testing windows, while avoiding fabric in typical crack-prone zones.
