Agate Gray has the fine, linear streaking of travertine, in a light gray with a touch of beige. It’s a 12x24 gray travertine vinyl tile from the Kalla Travertine design in Armstrong Alterna’s line, with a low-gloss finish.
It isn’t ceramic or porcelain. It’s vinyl that Armstrong positions as an alternative to stone, ceramic, and porcelain, with a surface that’s warmer to the touch and kinder to your feet. It’s waterproof and glued down across the whole back, with approval for every grade. Armstrong’s grout list for it has one entry Mist. A residence is covered for life and a light commercial space for five years, both under limited warranties.
