Roca Tile Pro Concrete Matte Porcelain 24" x 24"

Roca Tile's Pro Concrete is a 24" x 24" matte porcelain tile in a concrete look, flat and evenly clouded and 9 mm thick. Roca Pro Concrete is for the hardest-worn floors in a house and for retail and hospitality. It solves a floor that will be walked on all day for years. That is what the PEI 5 wear rating means in practice. A dynamic coefficient of friction of 0.42 or above clears the ANSI A326.3 threshold of 0.42, so it is rated for a level interior floor that gets wet. Water absorption of 0.5% or less is the figure that makes it a porcelain rather than a ceramic. The trade-off is light. A matte face hides dust and water spotting far better than a polish, but it will not bounce light into a dark room the way a gloss does. The edges are rectified, cut square after firing, which lets a tiler close the joint to about an eighth of an inch. It also means the substrate has to be flat, because a tight joint leaves nowhere to hide a dip. Pair it with a matching bullnose or a metal trim at the edges, an uncoupling membrane over a concrete slab, and a large-format mortar, because a tile this size needs full coverage under it. A box of Pro Concrete tile holds 6 pieces and covers 23.25 square feet. Order the area you are covering plus about ten per cent for cuts and breakage.
