TEC 316 HydraFlex Waterproofing Membrane 1 Gallon

TEC 316 HydraFlex waterproofing membrane is a liquid-applied crack isolation and waterproofing coat that goes down before you set tile. Roll or trowel it over the substrate in showers, floors, and wet areas to keep water from reaching what's below and to bridge minor cracks that would otherwise telegraph up through the tile.

This 1 gallon pail is ready to use, no mixing. Apply it in coats over concrete, cement board, and other approved substrates, let it cure between coats, and set tile directly onto the membrane. It works for both crack isolation and waterproofing in one step.

Installers rely on HydraFlex to protect the assembly under showers and floors. Tile Outlets stocks the 1 gallon size for bathroom and wet-area builds.
