Pro Cement is a 24" x 48" porcelain tile with rectified edges, cut square after firing so the grout joint can close to about an eighth of an inch. It gives the flat, quiet tone of a poured floor with none of the curing or cracking. Porcelain is pressed and fired denser than ceramic, which is what lets it take water, frost and daily traffic. A matte face holds light rather than throwing it back, so it hides dust and water spotting between cleans. Porcelain of this density suits floors and walls through the home. A large format means fewer grout lines, so a floor reads as one continuous surface. Order the area you are covering plus about ten percent for cuts and waste.
