Laticrete Hydro Ban Waterproofing and Crack Isolation Membrane

Laticrete Hydro Ban: Waterproofing and Crack Isolation Membrane

Laticrete Hydro Ban is a thin, load-bearing, single-component liquid rubber polymer designed to provide waterproofing and crack isolation beneath tile, brick, and stone installations. It cures to form a flexible, seamless membrane that bonds directly to a wide variety of properly prepared substrates.

The membrane provides antifracture protection over shrinkage and other non-structural cracks up to 1/8" (3 mm) and exceeds ANSI A118.10 and ANSI A118.12 requirements. Its thin cured profile of approximately 0.020–0.030" (0.5–0.8 mm) helps provide protection without significantly increasing assembly thickness.

Hydro Ban does not require reinforcing fabric in standard field, cove, or corner applications, simplifying installation. The membrane can bond directly to metal and is compatible with PVC and ABS plumbing fixtures as specified by the manufacturer.

The rapid-drying formulation supports faster installation schedules. Once properly cured, tile, brick, and stone can be installed directly over the membrane. The color changes from light sage to olive green as the product cures, providing a visual indication for inspection and installation readiness.

Hydro Ban also incorporates antimicrobial product protection designed to inhibit the growth of stain- and odor-causing microbes on the waterproofing membrane. The non-flammable formulation is IAPMO approved and carries an Extra Heavy Service rating according to TCNA performance levels based on the ASTM C627 Robinson Floor Test.

Key Features and Benefits

• Waterproofing and Crack Isolation
  Provides a seamless waterproofing and crack isolation layer that helps protect tile and stone installations from moisture and non-structural substrate movement
• Single-Component Formula
  The self-curing liquid rubber polymer is ready to apply without requiring on-site component mixing
• No Fabric Required
  Does not require reinforcing fabric for standard field, cove, or corner applications, helping simplify installation and reduce labor
• Antifracture Protection
  Provides crack isolation protection over shrinkage and other non-structural cracks up to 1/8" (3 mm)
• Rapid Drying
  Fast-drying formulation allows flood testing in approximately 2 hours at 70°F (21°C) or higher, when properly cured according to manufacturer requirements
• Thin Membrane Profile
  Cures to approximately 0.020–0.030" (0.5–0.8 mm), providing waterproofing and crack isolation without adding significant thickness
• Visual Cure Indicator
  Changes color from light sage to olive green as it cures, providing a clear visual indication of membrane readiness
• Antimicrobial Protection
  Integrated antimicrobial technology helps inhibit the growth of stain- and odor-causing microbes, including bacteria, mold, and mildew, on the membrane
