The most protective roll on tile underlayment on the market!

Ardex 8+9 Product Information

ARDEX 8+9 is a two-component system consisting of a solvent-free, acrylic-based liquid combined with a Portland cement-based powder. When mixed and applied, these components produce a flexible, waterproof coating that protects moisture-sensitive substrates from water from above and provides an excellent bonding layer for ceramic tile setting materials. 8+9 can be applied with a roller. Essentially, you’re creating a waterproofing barrier layer that protects your floors. ARDEX 8+9 can also be used as a waterproofing barrier in tiled showers.
