Laticrete Hydro Barrier Waterproofing Membrane

Laticrete 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.
