Laticrete Hydro Ban is a thin, load bearing waterproofing/crack isolation membrane that DOES NOT require the use of fabric in the field, coves or corners.

Laticrete Hydro Ban Waterproofing Membrane

LATICRETE Hydro Ban is a versatile waterproofing membrane that LATICRETE has developed to eliminate the need for the use of fabric in the field, coves, or corners. Hydro Ban is a liquid rubber polymer that can be applied in a similar fashion to paint, forming a flexible and seamless waterproofing membrane over the surface. The thin, load bearing waterproofing membrane is self curing and provides anti-fracture protection of up to 1/8” (3 mm) over shrinkage and other non-structural cracks.

This product meets the following vendor part numbers:

  • 1 gallon: Vendor Part No. 9255-0401-2
  • 5 gallon: Vendor Part No. 9255-0005-2

Easy to Apply & Fast to Cure

The waterproofing membrane is easy to use and apply. LATICRETE Hydro Ban can be applied right out of the pail using a paint brush, paint roller, or trowel over a suitable substrate. After curing, tile, brick, and stone can be installed directly onto the membrane. A fast curing time (when cured at 70°F (21°C) and 50% RH) allows for foot traffic in 4 – 6 hours and for flood testing in 24 hours. When fully cured, the membrane changes in color from a light sage to an olive green.

Use for Showers & Other Waterproofing Applications

LATICRETE Hydro Ban is ideal for a variety of applications that require waterproofing. Containing Microban antimicrobial product protection, the waterproof membrane is IAPMO (International Association of Plumbing and Mechanical Officials) approved. Hydro Ban can be used in both interior and exterior applications including showers, bathrooms, swimming pools and hot tubs, fountains and water features, kitchens, counter tops, facades, and terraces and balconies over unoccupied spaces.

    5-Star Product

    Posted by Jason on Dec 30, 2022

    The 5 gallon bucket I ordered was shipped in a cardboard box with a handful of styrofoam peanuts thrown in. The box must've gotten bumped in transit, becuase the bucket's lid was not sealed when I opened up the box. Some of product had leaked out, and it was a real mess to clean up. I opted to not make a fuss, since 99.9% of the product was intact and totally usable. Still, it should have been packaged better.
