Inspired by the ancient houses of Salento, the tiles from the Effetto Petra di Ostuni collection by Cerdomus, with antiqued edges, revive the authentic feeling of stone paving. The chiseled edges give the effect of the aged natural stone. This porcelain stoneware is offered in multiple sizes and finishes to support both interior and exterior solutions. Exterior installations include on grass, gravel, or sand, raised terraces or glued to a screed for floors passable by cars.
