The meaning of tile paving

Tile paving is a technical activity, and many of them are exquisite. The purchase of the products reflects the quality of the workers. If the processing work before the paving is ignored or the operation is not standardized, it is very likely to cause the phenomenon of empty tiles and large chromatic aberration, which greatly affects the overall aesthetics. Therefore, the acceptance of the tile is to check the quality of the tile paving from the aspects of flatness, aesthetics and safety.

The acceptance process of tile paving:

The first step is to check if the corner is flat.

With the right angle of the square object, it is necessary to check the corner of the cabinet in the future. Because it is not a right angle, the cabinet installation will leave a gap, which affects the appearance;

The second step is to check whether the positive angle is right angle

Compare two tiles with each other

The third step is to check whether the wall tiles have empty drums.

Focus on the edges and corners of the tiles, these parts are most prone to empty drums

The fourth step is to check if there is any jumping phenomenon.

“Jumping Porcelain” is to check whether the edges of the tiles are cut neatly when checking the yin and yang angles and cutting the tiles.

Step 5 Check if the wall tiles are flat

The main point of the tile is to touch the joint of the tile and the joint of the four corners. If the corners of the tile are flat, there is a convexity and concave in the middle, which may be the problem of the tile itself.

Tile precautions

A look at whether the original foundation treatment is in place before the paving

The base layer should be chiseled with a chisel depth of 5 to 10 mm and a chisel mark spacing of about 30 mm. According to the construction process requirements, if the original wall surface has putty before the wall tile, the putty should be removed, and then the smooth plaster layer should be chiseled and the surface cleaned, then the gray ash should be used, and finally the tiling. Otherwise, the tiling cement and the base layer are not firmly bonded, which causes the wall tiles to appear empty and delaminated.

Second, see if the cement mortar on the back of the tile is full.

The mortar behind the tiles should be full to ensure that the corners are not empty. According to the regulations, when the wall tiles are laid, the mortar should be full and firmly adhered, and the empty corners of the wall should not exceed 5 percent of the number of paving. When paving bricks, it is better to use 1:2 cement mortar, the thickness should be 6 to 10 mm, and then use a rubber hammer to lightly compact, otherwise it is easy to appear empty.

Third, look at the tiles with or without color difference

Apparent chromatic aberration appeared in the adjacent two wall tiles. According to the relevant regulations, the variety, specifications, grades, colors and patterns of wall tiles should meet the design requirements. After the paving, the color of the tiles should be basically the same, no obvious color difference, no clean matter and no slurry marks.

Fourth, look at the corners of the tiles (yin and yang)

The tiles at the corners of the corners were cracked because they were not handled properly. Workers usually use light steel keels to make the skeleton of the kitchen and the riser, with cement pressure plates and metal mesh. After tiling, because the physical expansion coefficient of light steel keel and cement is different, the skeleton is easy to be deformed, and the possibility of cracking at the corner of the wall brick is greater. It is recommended that the owner, the kitchen and toilet bag riser, have a better foundation with light bricks.

Five look at the wall tiles whether there is a "small strip"

The size of the innermost mosaic of the wall is obviously small. It should be calculated in advance and placed as far as possible in an inconspicuous place. According to the regulations, the laying line should be positioned and the bricks should be arranged before laying bricks. The non-whole bricks should be discharged to the secondary or female corners. It is not advisable to have two rows of non-whole bricks on each wall, and the width of non-whole bricks should not be less than one third of the entire brick.

Six look at the flatness of the wall

Use the instrument to check the flatness of the wall. According to the regulations, the flatness and verticality of the wall surface are within 2 meters, and the error is not allowed to exceed 4 mm. Otherwise it will affect the flatness of the tile.

The main thing to pay attention to in this step

1. For the newly paved floor tiles, you can't walk on them, because the bricks are not dry, so as not to cause the brick surface to be uneven.

2. For the newly paved floor tiles, the tiled boxes (preferably tarpaulins) must be used to cover the tiles, to prevent the sand from damaging the bricks, as well as the paint and glue used in the decoration and the glue on the bricks. , polluted brick surface.
