Description
Overview
LATICRETE HYDRO BAN is a liquid-rubber waterproofing and crack-isolation membrane that forms a flexible, seamless layer beneath tile. The self-curing liquid is applied without reinforcing fabric in the field, coves and corners when the specified gap and detail requirements are met.
Features
- Light-sage to olive-green color change assists cure inspection.
- Bonds directly to metal, PVC and ABS plumbing fixtures—not an unrestricted approval for all surfaces of those materials.
- Antimicrobial technology protects the treated membrane.
- Solvent-free and non-flammable.
- Tile, brick and stone can be installed directly onto the cured membrane.
Specifications
- Cured thickness: 0.020–0.030 in. (0.5–0.8 mm)
- Approximate coverage: 1 gallon: 50 sq. ft.; 5 gallons: 250 sq. ft.
- Crack protection: Up to 1/8 in. (3 mm), shrinkage and other non-structural cracks
- Standards: Exceeds ANSI A118.10 and A118.12; IAPMO approved
- Service rating: Extra Heavy under TCNA/ASTM C627
- Flood testing: As soon as 2 hours at 70°F (21°C) or higher, subject to the complete curing instructions
- Size: 1 Gallon; 5 Gallons

Applications
Use for specified bonded waterproofing assemblies over suitable concrete, masonry, mortar beds, cement plaster and cement backer board. Existing tile/stone and cement terrazzo require a latex-thin-set skim coat. Exterior-glue plywood, gypsum wallboard and poured gypsum underlayments are interior-only substrates.
Plan Your Installation
- Inspect joints and gaps before application. The fabric-free detail is qualified for gaps of 1/8 in. or less; follow DS 663.5 for the full treatment.
- Apply and verify the required thickness rather than relying solely on estimated pail coverage.
- Use the installation instructions for penetrations, changes in plane and flood-test readiness.
- Follow the applicable TCNA methods F200, RH122 or F180 for poured gypsum underlayment.
Common Planning Questions
Does the color change alone determine when to flood-test?
Use the full curing conditions and timing in the instructions. A color change is a useful inspection aid, not a substitute for the complete requirement.
