Projolly Square is a square shaped as a right angle that is versatile and suitable for various laying solutions, both for floors and coverings. It is used as a staff angle for external corners of tile coverings. It facilitates laying and eliminates the brittle unpredictability of ceramic tiles. It is also used as a finishing square for finishing wall coverings, raised platforms, steps, and baths, and is used as an edge and a skirting board for parquet, natural stone, moquette and epoxy resin coverings. It guarantees flawless work done with care that is of great aesthetic merit. It strengthens tile edges with a square finish, protecting corners efficiently, avoiding chipping and breakages resulting from knocks. This is required by the new European regulations on safety and accident prevention in public and private places.
