Which is better, ordinary post or book post?

What you are asking is which is better, normal tiling or thin tiling, and each has its own advantages. First of all, the two methods use different materials. The traditional sticking method only needs cement and sand, and even the whole tile needs some adhesive. The thin tile sticking method needs tile adhesive and cannot be mixed with other materials, so the material cost is much higher than the traditional sticking method. Secondly, the cost of these two kinds of paving is similar, but the requirements of thin stickers are very high. Find the wall of the room before sticking bricks, not only horizontally, but also vertically. Adding this program will increase the cost of the owner. In addition to beauty, customers choose the thin paste paving method because they want to expand the room space, but this is only an ideal state. If the flatness of the room is particularly good, you can directly tile it, which can increase the room space, but in more cases, you need to level it in advance, which takes up room space invisibly, just like traditional tiling. During normal paving, because the cement mortar is thick and the wall is slightly uneven, it can be leveled directly without leveling in advance.
