Before laying tiles, it is recommended they are stored at room temperature 60°F-70°F (15°C-20°C). The tiles can be loose laid on flat, dry floors free from impurities such as oil, grease etc. Cracked floors should be filled, and uneven floors covered with hardboard. Dusty floors should be primed. Because of the high insulation value of these tiles it is not recommended they be laid when under-floor heating systems are in use.
On very large installations, it is advisable to secure 1 in 5 rows with double-sided tape Where tiles are to be used under caster chairs, tiles should be fully secured. The tiles may be laid by marking across in the center of the room and working outwards from this, the marker cross may be moved to facilitate these of full tiles in doorways, etc.
Tiles must be laid by turning alternate tiles through 90 degrees to obtain a checker pattern. An arrow on the back of each tile indicates the pile direction. Only tiles with the same batch number should be laid together.
