TECH TALK –––––––––––––––––––––––––––––––––––––––––––––––––––––––––– ARDEX Americas introduces ARDEX S 1-K™ One-Component Waterproofing and Crack Isolation Membrane specifically designed for use in bathrooms, showers and other wet areas prior to the instal- lation of tile. Recommended for use over a wide range of substrates and finish- es, the highly workable consistency can be applied with a paint roller or brush, while minimizing drips and splatters. The new waterproof- ing compound offers outstanding coverage at nearly 57 sq. ft. per gallon in two coats, while flood test- ing can begin just after 12 hours. ARDEX S 1-K is also ideal for isolating minor, in-plane substrate cracking up to 1/8” (3mm). Available in two sizes (large 3.5 and small 0.7 gallons), the convenient oval-shaped con- tainers easily accommodate a paint roller and are resealable for continued use. ARDEX S1-K exceeds ANSI A 118.10, ANSI A 118.12, and is IAPMO certified. www.ardexamericas.com Va., concurred, saying, “We pay particular attention to this informa- tion and if we have any concerns they are discussed with the home- owner or GC before proceeding.” Safety on the rails The focus group was also asked about handrails and grab bars. Commercially focused tile compa- nies are not likely to install grab bars, probably because other trades or the manufacturer will do that work, said NTCA Technical Trainer Robb Roderick. But residentially oriented companies seem to be installing them more and more, “especially in basement bathrooms that often serve as guest baths for clients with aging parents,” said Gianna Vallefuoco of Vallefuoco Contractors in Rockville Md. Collins agreed, saying his company puts them into about half the showers they build. Typically, he said, they install blocking (2” x 8” or 2” x 10”) between the wall studs where the grab bars will be installed after Long gone are yesteryear’s grab bars. Safety accessories for the bathroom are now attractive and available in every style and finish, and price point. 72 TileLetter | January 2019
