In theory, dry paving method should be adopted for floor tiles, and floating sand and sundries should be removed after the grass-roots level is watered and wetted. Wipe the adhesive layer, use one to three layers of dry cement mortar, level it, put the brick on the mortar and tamp it with a rubber hammer, remove the ground brick and pour the mortar, then stabilize and tamp the ground brick.
Dry paving method can effectively avoid the occurrence of bubbles and empty drums in the process of floor tile paving, but because of its high labor intensity and high technical content, dry paving method is much more expensive than wet paving method.

Matters needing attention
1, and the floor tile laying temperature should be better than 10℃. Before laying, the floor tiles should be placed face down on the construction site for more than 24 hours, so that the temperature of the floor tiles is the same as the room temperature. Try to keep the room temperature constant during laying.
2. Floor tiles can be cut into triangles, rectangles and other shapes besides squares.
3. Before laying, draw a cross datum line on the ground. The method is: measure the size of the ground, draw a vertical line or horizontal line in the center of the ground, and then make a vertical line through the center of this line.
