Just like any other floor covering, Allura Puzzle requires a subfloor that is ready to be laid, but under certain conditions solid, level and dry old subfloors can also be covered. Laying begins in the middle of the room based on a plan. The square tiles are laid monolithically, i.e. cross-jointed, loosely on the subfloor - without the use of adhesives. The edges of the Allura Puzzle tiles have connectors on four sides. This ensures that the tiles are connected to one another according to the dovetail principle. For assembly, the connectors are closed flush with a rubber mallet, starting from the corners, without tilting. A gap of 3 to 5 millimetres should be planned for walls, door frames and other finishes. Straight cuts are made by scoring the surface with a trapezoid blade, then folding it over and finishing with a hook blade. Round cuts, for example on pillars, are easier to make if the floor covering is heated beforehand.
