The living room and dining room are better tiled or laminate

It is good to level directly with cement mortar.

There is a problem of leveling between floor tiles, even if there is a height difference in the kitchen and bathroom, living room, you can use ash leveling. However, the version of leveling should still be based on the living room to do dry paving, because the general living room area is larger, there are likely to be some errors when pouring the floor slab, and the kitchen and bathroom area is small, and the error is relatively small. Generally, the thickness of the cushion is about 2-4 cm, and the thickness of the tiles is obviously higher than the thickness of the laminate floor, here I recommend laying a layer of moisture-proof film first, and then according to the height of the floor tiles to buy the corresponding height of the MDF (fire core board) to make a low lining, so as to avoid the unevenness of the floor due to too much moisture-proof film (if the moisture-proof film is too thick, the wardrobe and the bed will sink under normal pressure).

The size is recommended to be 800*800, and the type of tile depends on your personal preference and decoration budget. >>>More
