If you want to lay laminate flooring over tiles, you have to ensure that the tiles are healthy, without any structural damage. Once you’ve inspected the tiles, you have to ensure that the floor is even. Next, add underlayment to protect the laminate from moisture.   When this is all done, you can start laying the planks. Since this is a floating floor, there’s no need for adhesives or glue to attach it to the subfloor. After laying the first row, start the second with a smaller plank to achieve a visually pleasing surface.
