Light Gray is gray with taupe and brown clouding, lighter in some spots and darker in others. It’s a 12x24 stone-look tile from Armstrong Alterna’s Mesa Stone design, with a low-gloss finish. Armstrong’s pattern guide covers a straight lay and a brick stagger, and says to use one dye lot for the whole job, so order every box together.
This one’s waterproof and goes down in full spread, with approval at every grade. Grout is optional; S-693 premixed sanded acrylic is the one Armstrong specifies, and it shouldn’t be sealed. Armstrong’s warranty is lifetime limited for residential use and five years limited for light commercial.
