After spreading the adhesive, lay the first tile. Then, slide the the clips underneath, so that on each side there are two clips at a distance of approx. 4-8 cm from the corner of the tile.
Place another tile, pushing it towards the clips. Insert the wedge into the opening in the clip (pressing) to align two tiles.
Wait until the adhesive dries. To remove the clip, simply use a rubber mallet or just kick it.
