  • HYDRO BARRIER is a thin, load bearing, self curing liquid rubber polymer which can be easily applied to form a flexible seamless waterproof/anti-fracture membrane
  • HYDRO BARRIER can be used on interior and exterior, horizontal or vertical surfaces and is approved by IAPMO for use as shower pan liner
  • Coverage: 50 sq ft / gallon
  • HYDRO BARRIER can be applied using a paint brush, roller, trowel or airless sprayer
  • All areas must have two coats to ensure waterproofing capabilities
  • When the second coat is applied the substrate will not show through HYDRO BARRIER if coated with 0.020–0.030" (0.5–0.8 mm) of dried membrane. Color changes from a light blue to darker blue when fully cured

Will this stop water from leaking in a basement wall when it rains?

This product is designed to be a waterproofing layer between the suitable substrates and your tile installation. It is not designed to stop leaks.

I am looking at applying Hydro Barrier to a plywood base on a deck. After allowing it to dry, I would then glue tongue and groove deck boards over top. My question is whether there are specific kinds of glue that will adhear with Hydro barrier to avoid buckling?

I can be contacted at markc91754@comcast.net. Thank you.

Laticrete does not specify the best type of adhesive to use over Hydro Barrier. However, they do advise to not use any solvent-based adhesive directly on the Hydro Barrier.
