LATICRETE HYDRO BARRIER Waterproofing Liquid 3.5 Gallon Pail

LATICRETE HYDRO BARRIER Waterproofing Liquid 3.5 Gallon is the contractor-friendly solution for fast, affordable ANSI A118.10 waterproofing. Consequently, you can protect showers, pools and balconies without the premium price of HYDRO BAN^[link]. Moreover, the flexible liquid forms a seamless membrane that resists cracks up to 1/8 inch, ensuring peace of mind for tile installations large and small.

Benefits of LATICRETE HYDRO BARRIER Waterproofing Liquid

First, the self-curing film is walkable in just 4–6 hours, so schedules stay on track.
Furthermore, Microban® antimicrobial protection actively inhibits mold and mildew.
In addition, the coating earns an Extra-Heavy Service rating in the TCNA Robinson Floor Test.
Finally, its low-VOC, non-flammable formula is safer for occupied interiors.

How to apply LATICRETE HYDRO BARRIER Waterproofing Liquid

Because the product is premixed, application is simple:

Prepare the substrate so it is clean, sound and free of standing water.
Roll on the first coat at ≈ 0.02 in (40 mil) wet film thickness.
Afterward, allow 1–2 hours of drying—then apply a second coat at right angles to the first.
Therefore, a full 3.5 gal pail covers roughly 175 ft² at the recommended 80 mil total dry film.

Typical installations

Bathrooms, tub surrounds, spas, commercial kitchens, balconies, fountains and planters all benefit from reliable liquid waterproofing. However, continuous steam rooms require LATICRETE HYDRO BAN® instead.

Pair it for an extended LATICRETE System Warranty

Combine HYDRO BARRIER with 254 Platinum thin-set and SpectraLOCK® PRO Premium grout, and you can register for up to a 25-year system warranty.

Why choose a liquid waterproofing membrane?

Unlike sheet membranes, liquid products conform to every corner and penetration. Consequently, there are no seams to fail. Additionally, the film acts as an anti-fracture layer, thus reducing callbacks caused by substrate movement.
