The floor tiles that have been pasted for a few years are arched, whose responsibility is it

Generally speaking, it is the responsibility of the renovation company.

There are three main causes of floor tile cracking:

First, the expansion gap between the floor tiles and the floor tiles and the surrounding walls is too narrow, and when the room temperature changes drastically, the floor, cement layer and ceramic tiles will appear thermal expansion and cold contraction. If the gap is too thin and there is not enough space for the tile to "stretch", the tile is easy to arch, which is generally easy to appear in the northern region, while the south is not easy to appear due to the high humidity and small temperature difference.

The second is that the cement and yellow sand are not mixed in the correct proportion when laying the floor tiles. If the cement grade is low and the yellow sand is put too much, after a long time, the cement in the lower layer will not be able to bond the floor tiles, causing the floor tiles to be upturned.

Another relatively rare reason is that if the original cement floor is very smooth, it is easy to arch the tiles without hairing.

First, check the floor tiles in the entire store or room to see if the tiles are arched individually or in large areas. When inspecting, you can use to tap the tile, if the sound is empty, it is already hollow, that is, the tile has been separated from the cement layer. Such tiles can easily crack if they are barely pressed down.

Therefore, it is necessary to pry up the arched tiles, re-pavement, and if there are a large number of hollow tiles, they should simply be re-paved in their entirety.

First, the joints between the arched tiles and other tiles are sawed with a cutter (there will be a lot of dust when cutting, so you need to keep adding water to the cutter), and you must lift the tiles very carefully, and the action must be light, otherwise it is easy to cause the tiles to crack.

Scrape off all the cement mortar that sticks to the edge of the tile. Treat the cement layer under the bricks, plane off 1-2 cm and clean it up.

3. Floor tiles: 1:2 - 3, the cement number of cement is cement.

In addition, if white cement is used, be sure to use 108 glue, which can make the cement and floor tiles tightly bonded.

Re-pave and flatten the cleaned tiles, and then use a caulking machine to reinforce the cement after the cement is completely dry, so as to avoid the phenomenon of upturned and cracking of the floor tiles.

When choosing floor tiles, it is important to consider the following aspects: First, it depends on the brand. Only well-known brands of floor tiles, the quality of their building materials can meet the national standards, and the content of harmful substances can be within a safe range.

Second, it depends on its anti-pollution ability, if the family is very busy and can only clean once in two or three days, then choose the one with better anti-pollution ability. Third, if there are elderly people and children at home, you must do a slip resistance test when purchasing.

Specifically, the selection of floor tiles can start from the following aspects:

1.To see if the color of the tile is pure. Mainly observe whether the color of the back of the tile is uniform and consistent.

2.It is necessary to observe whether the particles of the cross-section of the tile are fine. The cross-section here does not refer to the cutting surface around the tile, but to the fracture of the tile fragment.

Generally speaking, the fracture is fine, hard and brittle, and the color is the same. Because the ceramic tiles with fine particles have strong waterproof ability, while the tiles with large particles are easy to soak in moisture, which affects the quality.

3.Pay attention to the thickness of the glaze layer. The thickness of the glaze layer is the thickness of the cross-section of the glaze. Glaze is the most expensive material in the cost of ceramic tiles, and the thicker the glaze, the better the quality.

4.To listen. Tap the tile to pay attention to whether the sound is crisp, such as the sound is clear and pleasant, such as the sound is dull, it is inferior.

5.Test the waters. Consumers can pour some water on the back of the tile and pay attention to how quickly the tile absorbs water. After a few minutes, see if the marks left by the water on the front are obvious. The density of tiles that infiltrate slowly after the water disperses is large, and the marks left by the water are not obvious, so they are regarded as the top grade.

6.Warp. Take two bricks back to back and face to face to see if they can be in close contact, and there is no phenomenon that the gap is too large to judge whether there is warping.

7.Infiltration. Find ink to apply to the surface for 1 hour and then scrub to see if there are traces, no traces are good bricks, and those that have infiltration are resolutely not selected.

1. Small manufacturer products, no quality assurance, quality problems are not surprising.

2. There is no problem with the product quality itself, but the installation quality of the installation master is not in place, which lays the bane for future warping.

Therefore, if there is a quality problem in two or three years, it is the responsibility of the seller, if the brand manufacturer, will sign a warranty period, generally more than 10 years.

The quality problem is expired, find someone to fix it.
