Proline brings the timeless beauty of slate to decorative concrete with the classic Ashlar Stone pattern — a design that traces its roots back to the 12th century and remains prominent in Western architecture. Our Old Granite Cleft Stone texture offers a natural, authentic look that enhances any surface. This 3-piece stamp set features color-coded mats to minimize repetition and ensure a seamless, open pattern. Built tough and precision-fit, each stamp measures 24″ x 24″ for a perfectly balanced finish every time.
