"Used for the first time on my daughters new build house. Two bathroom floors to tile. The rooms aren't that big so difficult to move around. This was so much easier than cutting and screw fixing ply boards to the floor. Simply cut to shape, lay the quick setting tile adhesive with notched trowel then press the mat into place, trowel over again with straight edge, scraped away excess adhesive - job done., took no more that half an hour in total to lay 4 sqm. Tiled in the afternoon, fantastic job. There's a great product video that shows you exactly how to use it - but its really simple anyway..."
