HYDRO BAN is a liquid waterproofing membrane that you brush, roll, trowel or spray on, and it dries into a thin, seamless, flexible layer. It is a single-component, self-curing rubber polymer, so there is nothing to mix, and it does double duty as a crack isolation membrane, protecting tile from shrinkage and other non-structural cracks up to 1/8 inch. Cured, the film is only 0.020 to 0.030 inch thick, and you can set tile, brick or stone directly on it.
The big difference from a sheet system is what you skip. HYDRO BAN does not need fabric in the field, in coves or in corners, and it bonds straight to metal, PVC and ABS plumbing fixtures. If you want extra reinforcement at cracks, joints, curves, drains or penetrations, Laticrete allows a 6 inch waterproofing and anti-fracture fabric there, but it is optional.
It is rated for a long list of wet jobs: shower pans, stalls and tub surrounds, bathrooms and laundries, swimming pools, fountains and water features, spas and hot tubs, kitchens and food processing areas, and balconies and terraces over unoccupied space, indoors and out. Steam rooms are on the list too, as long as you add a vapor barrier. HYDRO BAN is not the vapor barrier.
You apply two coats, and the color tells you where you are. HYDRO BAN goes on light sage green and cures to a darker olive green, so thin spots and missed areas stand out before they get buried under tile. Wait until the first coat has turned olive before applying the second. After the final coat has cured, you can flood test in as little as 2 hours at 70°F, which keeps a tight schedule moving.
HYDRO BAN carries a “Extra Heavy” rating on the ASTM C627 Robinson Floor Test and exceeds ANSI A118.10 and A118.12. It has ICC-ES report ESR-2417, IAPMO approval and a Miami-Dade NOA, and it is UL GREENGUARD certified for low chemical emissions. Antimicrobial protection is built in to help keep the membrane itself free of stain- and odor-causing mold and mildew. For shower pan use, get approval from your local building code authority first.
This listing is the 5 gallon pail, which covers about 250 square feet with two coats.
Tile, thinset and grout do not waterproof a wall or floor. Laticrete says so plainly: mortars, adhesives and grouts are not replacements for a waterproofing membrane, so wherever water has to be kept out of the structure, a membrane goes under the tile.
Liquid and sheet membranes both do the job. A liquid membrane like HYDRO BAN wraps corners, curves and drains in one seamless coat and needs no fabric in the field, coves or corners. The trade-off is that the waterproofing depends on the film you actually apply, so you need two full coats and a wet film gauge to check thickness, then a flood test before you tile. If you are comparing a liquid waterproofing membrane for a shower or a floor, look for two things on the data sheet: a waterproofing standard such as ANSI A118.10, and a crack isolation rating such as A118.12. HYDRO BAN meets both.
To determine approximate delivery time for your order shipped via UPS Ground, please locate the zone where the Ship-To address for your order is located. Note the color of that zone then check the number of days listed next to the color in the Transit Days Chart on the bottom right of the Zone Map. Please note that the delivery time is calculated beginning the day after your order has shipped.
After the second coat, the wait before tiling depends on what is underneath:
Actual times shift with the substrate, temperature and humidity.
A 5 gallon pail covers about 250 sq ft (23.2 m²) with the two required coats. Each wet coat covers roughly 100 sq ft per gallon. Spraying uses more product because of bounce-back and overspray.
Laticrete lists four warranties for HYDRO BAN in the US: a 1 Year Product Warranty and 10 Year, 25 Year and Lifetime System Warranties. The system warranties are tied to LATICRETE system installations, so review the documents before you plan the job.
It is a single-component liquid waterproofing and crack isolation membrane. You apply it with a brush, roller, trowel or sprayer, it cures into a thin, seamless, flexible layer, and you set tile, brick or stone right on top.
Not in the field, coves or corners. Laticrete does allow a 6 in. waterproofing and anti-fracture fabric at cracks, joints, curves, corners, drains and penetrations if you want extra reinforcement. For gaps 1/8 in. or smaller, follow the instructions in DS 663.5.
Two. Every area needs two full coats, each about 0.015 to 0.022 in. wet. Let the first coat cure to a uniform olive green before applying the second.
About 250 sq ft with two coats. Each wet coat covers roughly 100 sq ft per gallon. Spraying uses more because of overspray.
About 2 hours after the final coat has cured at 70°F and 50% RH. At 50°F to 69°F, wait 24 hours. Cold or wet conditions need longer. Make sure no light sage areas are left before you test.
Once the membrane is dry to the touch you can set tile with latex thinset. After the second coat at 70°F, time to tile is about 50 minutes over concrete, 30 over cement board and 15 over fiber cement underlayment.
HYDRO BAN goes on light sage green and cures to olive green. The color change shows you when a coat has cured and helps you spot thin or missed areas.
Yes. Shower pans, stalls and tub surrounds are listed uses. Get local building code approval before using it in a shower pan, apply two full coats, and flood test before tiling.
Yes, pools, fountains, spas and hot tubs are listed uses. In submerged jobs the membrane has to form one continuous pan with no voids, so do not apply it only at the waterline.
Not over OSB, particle board, interior glue plywood, luan, Masonite or hardwood. Exterior glue plywood is allowed for interior use only, on a floor that meets Laticrete’s minimum construction and deflection requirements. Do not install it directly over single-layer wood floors or plywood tubs, showers or fountains.
It provides crack isolation for shrinkage and other non-structural cracks up to 1/8 in. (3 mm). It is not for cracks wider than that, structural cracks, cracks with vertical movement, or dynamic expansion joints.
HYDRO BAN is listed for steam rooms only when used together with a vapor barrier. It is not a vapor barrier itself. Balconies and terraces are fine over unoccupied spaces, but it is not a primary roofing membrane over occupied space, and the membrane must be covered with tile, stone or brick. It can be left unprotected for no more than 30 days.
Laticrete lists a 1 Year Product Warranty and 10 Year, 25 Year and Lifetime System Warranties. The system warranties apply to LATICRETE system installations, so check the warranty documents for what your job qualifies for.
