Nexus is a contemporary extra large format porcelain tile that is perfect for large floor spaces. As it is a porcelain tile, Nexus can be used in any room in the home, and, with fewer grout joints because of its size, the effect will be of a free-flowing neutral and stylish area. Perfect for large-scale projects where quality but value is important. If the tile is being fixed to a concrete floor with or without underfloor heating we would recommend you purchase from us Ultra Tile Proflex SP: Rapid Set Flexible Tile Adhesive Grey 20kg. Work on 4 square metres of tiles for each bag of adhesive.
