What is the problem of cracked floor tiles in the living room?

(1) Large cracks appear on the surface of wall tiles.

Causes: Because of the cracks caused by wall settlement, most of the new houses are in the new houses, and there are relatively few in the old houses, if the base layer settles, it will lead to cracks in the bricks and wall paint on the surface. If there are regular or irregular cracks in several bricks, the owner can remove them to determine if it is a substrate problem.

If several floor tiles break in the same direction, and run through the room, but the floor tiles in other rooms do not change, it is also possible that the foundation of the house is deformed, such as the cracking of the floor slab or the cracking of the ground screed.

Solution: Check whether the changes at the grassroots level are serious, if they are serious, they may affect the safety of the house, and if they are not serious, they will not affect the use.

2) Cracks appear on the surface of the tile.

Causes of occurrence:1The quality of the tile itself is too low, which may also lead to cracking or cracks, but this situation is relatively rare, the quality of the brick is indeed too inferior, and the tensile resistance is too poor.

2.There is no soaking in water before paving, which leads to cracking of the brick surface due to the tensile force of the cement mortar. 3.

If the waterproofing and other base layers are not in place, it will also cause cracking of wall tiles.

Solution: If it does not cause hollowing and falling off, the cracking of the tile will affect the appearance, if it is troublesome, you can ignore it.

What kind of flooring are you using? How do you call floor tiles? If you are using flooring (wood flooring, laminate flooring, etc.), it is purely a quality problem of the flooring itself, and you should go to the supplier for compensation.

If you use floor tiles (full-body tiles, vitrified tiles and other tiles), there are several reasons for the cracking of floor tiles, the first is that the quality of the bricks is too poor (it is a substandard product, and the general regular suppliers do not sell this kind of goods), with the change of temperature, the internal stress of the floor tiles will crack the bricks; The second is that the deformation and cracking of the concrete floor (floor) structure will crack the bricks (usually the cause of the cracking of the floor tiles in this situation accounts for 75% and 85%), so in general, as long as the floor tiles are cracked from the middle, it must be the deformation and cracking of the concrete floor (floor) below; This situation is more troublesome to solve, to open the floor tiles paved at the cracks, look at the cracking of the ground, structural deformation (uneven subsidence, relative displacement, etc.), leave deformation joints at the deformation place, floor tiles also leave joints here, the width of the joints is 10 mm, and finally the joints are filled with silicone sealant; If the structure shrinks and cracks, lay a steel plate 200 mm wide and 8 mm thick, slightly longer than the cracking range at the crack (do a good job of anti-corrosion treatment), and then pave the floor tiles on top according to the normal procedure for floor tile restoration. The third is that the cement (poor stability, hydrated expanses, etc.) and sand (large mud content, soil clods, etc.) used when paving floor tiles have quality problems, resulting in local expansion of the mortar and arch the floor tiles, which occupies about 20% of the reasons for the cracking of the floor tiles, and there is no good way to deal with it, so the cracked floor tiles can only be lifted and repaved (pay attention to the quality of cement and sand used in repaving). Aojian summary.

1. Construction factors: no joints or too small joints when tiling.

The expansion coefficient of ceramic tile is much smaller than that of reinforced concrete, when there is thermal expansion and cold contraction, if there is no joint or insufficient joint, the expansion and contraction of the base layer is larger, and the tile expansion is too slow, resulting in the phenomenon of being torn apart. The crack texture is smaller and shorter, and cracks may occur at the corners.

2. There is no water soaking or insufficient water before the tile paste.

If there is no "full water" before the tile is paved, the embryo body will not absorb enough water, and the tile will absorb the water in the cement mortar after paving, so that the tile will crack, and in serious cases, it will also cause the tile to fall off. Tile cracking caused by insufficient soaking usually occurs soon after the paving is completed. However, now the production process of some ceramic tiles has reached the point where it can be directly paved without soaking in water, so it is recommended to consult the ceramic tile brand shopping guide or after-sales specialist before paving.

3. Manually cut tiles to cause dark cracks.

When the craftsman cuts the tiles, the tiles may be cracked due to improper operation. Dark cracks are generally not easy to detect, but after a long period of time, they will accelerate the cracking due to cement shrinkage, temperature changes, external stress, etc., and obvious cracks will appear. In particular, microcrystalline stone products should be treated with professional cutting machines.

4. Improper composition of cement mortar.

If the cement mark is too large, when the cement mortar is condensed, it will absorb a lot of water, and the water of the tile after paving is overabsorbed, it is easy to crack; If the cement content is too high, the expansion coefficient of the cement will be too large, which will also cause the problem of cracking of the tile.

Hello, when laying ceramic tiles, while ensuring the quality of cement, we should grasp the temperature of the space and the humidity of the cement, and we need to pay attention to the following points when laying:

1. Fill sand as the binding layer material for laying ceramic tiles, pay attention to the sand should be selected relatively evenly, and it is best not to have large lumps.

2. Smooth the sand, put tiles on it, pay attention to remove the small hard blocks while leveling, and the binding layer material should be uniform and stable. The thickness of the bonding layer should be 20-35mm; The bonding layer and the tile should be paved at the same time in sections, and it is advisable to use cement slurry or dry paving mud sprinkling water for bonding.

3. Place the vitrified brick carefully on the base layer, pay attention to the flush with the tiles laid in front, and compare whether there is any color difference or size.

4. Use a rubber hammer to gently knock the tile tightly to position, do not use force, if the joint layer is uneven, remove the tile and re-smooth it. Home decoration now depends on whether there is a plate between the tiles is not strict, the thickness of the plate is different, and the size error is large, otherwise the laying will affect the appearance.

5. Use the wooden square to check whether the tiles are laid according to the established height, and the device at the door is actually set up to locate the height of the tiles, in order to be able to match the height of the floor outside.

6. Now the tiles are docked on the joint layer to determine the height of the joint and the tile on the joint layer, so that you can be sure when laying.

7. When mixing cement, when using cement mortar bonding layer, the volume ratio of cement sand should be 1 4-1 6, and should be sprinkled with water and stirred evenly, and now more 425 cement is used.

8. Cement the back of the tile, and try to remove the floating soil on the surface of the tile before cementing, so as not to affect the bonding ability of the cement.

Provide you with a way to find someone.

1.Looking for a bricklayer, the composition is relatively high, several reasons can be caused Now it is basically a dry shop, where the hollow is possible, empty, there is a heavy object to overwhelm, it will crack, and there is a bricklayer dry shop did not pay attention to the small stones to carry to the will also crack, but I am afraid that the homeowner will know, not to mention that there is also a good spellYou can use a screwdriver's plastic part to gently knock on the rest of the good bricks and listen to the sound It's not the same empty much that's the bricklayer problem)

2 That's the quality of the floor tiles.

Generally, the cracking of floor tiles is mostly caused by the following reasons:

1: The workers who paved the floor tiles did not spread the cement all over to form empty bricks and trampled on or pressed to cause cracking. Generally, there are more cracks in empty bricks, and there is a muffled sound of empty bricks.

2: Blunt blow, such as a carpenter's hammer accidentally falling on the floor tiles This kind of crack usually has small pieces of floor tile fragments.

3: Floor tile quality problem.

I heard you say that it seems that a single corner of the floor tile is split, right? You can see clearly whether the crack is newly cracked or if it cracks when you don't pay attention when you pave it.

Find a decoration company to see if the flat water is not good and the leveling is not good, and then find a tile seller.

Not at the scene. It is estimated that the reasons are: the uniformity of the corners of the floor tile plastering (dry paving?) );Temperature deformation, backlogging, and moisture drying quickly are all related.
