For Immediate Release

Aliquippa, PA (January 24, 2017) – ARDEX Americas celebrates 40 years of innovation in 2018, and kicking off the celebration is our first new product announcement, ARDEX S 1-K™ One-Component Waterproofing and Crack Isolation Membrane.

ARDEX S 1-K is a single-component topside waterproofing compound that is extremely easy to use and produces a flexible waterproof coating perfect for use in showers, bathrooms and other wet areas. Recommended for use over a wide range of substrates and finishes, the highly workable consistency minimizes drips and splatters.


Flood test ARDEX S 1-K in 12 to 24 hours after the second coat has been applied. It also provides crack isolation up to 1/8” (3 mm). Available in two convenient sizes (large 3.5 and small .7 gallons), ARDEX S 1-K provides excellent coverage at nearly 57 sq. ft. per gallon in two coats.

“We’re excited to add to our waterproofing line this easy-to-use, single component solution,” said Russ Gaetano, ARDEX Senior Marketing Manager, Tile & Stone Installation Systems. “Everything about ARDEX S 1-K was designed to provide ease for installer, even the containers are oval shaped to readily accommodate a roller.”


ARDEX S1-K is now available for purchase at ARDEX distributors throughout North America.
