How to introduce the causes of uneven tiles?

When consumers choose tiles, in addition to considering the style and texture specifications, the quality of tiles is also very important. To identify the quality of a tile, we need to identify it from texture color difference, hardness, flatness and other aspects. Many people find that the tiles are uneven after decorating their houses. Next, I will give you an introduction on how to make uneven tiles. Let's get to know each other.

First, what should I do if the tiles are uneven?

1. The solidified cement is not dry; The situation is relatively simple. Only the decoration master tapped the floor tile with a wall knife until it was flush with other bricks.

2. The solidified cement has dried; This situation is more complicated. If a few bricks are uneven, use tools to remove the uneven floor tiles and replace them with new ones. After the batch of putty is brushed, it will be solidified with other cement.

3. If the floor tile is uneven in a large area. Suggest redoing everything. In order to avoid foot injuries when walking in the future.

4. If it is a small area. Then the uneven bricks need to be reworked. Free rework. If so, you need to buy new floor tiles and re-lay them.

Second, the reasons for uneven tiles

1. There is something wrong with the tile itself.

Tile arch back

Uneven tiles will have a fragile arch back due to high temperature firing. In fact, each tile is not absolutely flat, and the center is arched to a certain extent. Even if there is an error in the exact machine, it cannot be avoided. Usually, this weak arch will not affect the paving results. If the arch back exceeds the standard limit, paving will stop. Otherwise, after paving, the middle part of the tiles bulges seriously, and even a "small ditch" is formed between the tiles, and the workpiece must be turned over.

Tile warping

Tile inclination angle is also called floor deformation, mainly because the tiles are not burnt out. Ceramic tile formula uses high-temperature materials, and manufacturers add low-temperature materials to burn quickly. In the firing process, the fired low-temperature materials surround the high-temperature materials, forming vitrification on the surface, while the internal materials are not completely vitrified or vitrified. So after laying, due to the tension of cement and environment, the rebound deformation has a warping angle.

2. Environmental reasons

(1) foundation deformation

The captain said that due to geological problems, the building will have a certain degree of settlement. Different positions, different forces and uneven settlement. After a long time, the ground will be uneven and the tiles will be uneven. This is the so-called disadvantage.

(2) Temperature

The so-called daytime is the influence of temperature. When the temperature is too low or too high, the temperature difference changes greatly, which will lead to the deformation of ceramic tiles. In the north of winter, the temperature in the north is too low. The moisture in cement mortar binder will freeze and expand, destroying the structure and strength of cement mortar. In this case, the tile will become convex. Ceramic tiles will be deformed if they are heated for a long time.

3. man-made

Incorrect proportion of cement mortar

Traditional pavement usually uses cement and sand as binder, and the ratio of cement and sand is very important. Improper proportion, too high proportion of sand, or no adhesive is added to the mortar, all of which will make the cement mortar stick to the tile and the tile turn up.

The above is the introduction of uneven tiles that we have brought to you.
