Tile basics

A , the choice of tiles

It is mainly selected through several simple methods of “ seeing, hearing, listening, spelling, and experimenting. ” The details are as follows.

The first point: see

No matter what brand of product, the embryo body should have the brand mark of the ceramic tile, check the mark of the bottom embryo mark, and the product of the regular manufacturer's product has a clear product mark on the bottom embryo. If it is not or is particularly vague, it is recommended to choose carefully. ! " Look " mainly refers to the quality of the surface of the tiles. The following are introduced in terms of glazed tiles and vitrified tiles.

1 , glazed tiles: mainly to see whether there are black spots on the surface of the tile, bubbles, pinholes, cracks, with or without scratches, stains, missing edges, missing corners and other surface defects, the quality of bricks with many defects is relatively poor .

2 , vitrified tiles: vitrified tiles in addition to the brick surface to see if there are black spots, bubbles, pinholes, cracks, with or without scratches, stains, missing edges, missing corners and other surface defects, but also pay attention to whether there is leakage, Leakage and other defects.


The second point:

That is, the weight of the trial tile, for the same specification product, the quality and the high density of the brick hand are relatively heavy, on the contrary, the quality of the product is lighter.

The third point: Listen

By tapping the tiles, you can identify the quality of the tiles by listening to the sound.

( 1 ) Wall tiles or small size tiles

Generally, one finger is separated by five fingers , and the tile is pulled up . The other hand taps the face of the tile . If the emitted sound has a metallic texture , the quality of the tile is better. If there is no metal texture, the quality of the tile is poor!

( 2 ) Large-size floor tiles (vital tiles or antique tiles used in the living room and other floors)

Use a hand tiled side, tap the middle of the tile with the other hand's palm root, if the sound is thick and the echo is long, such as tapping the sound of a bronze bell, the porcelain is highly porcelain, wear-resistant Strong, high flexural strength, low water absorption, and less susceptible to contamination; if the sound is turbid, there is no echo, then the degree of porcelain is low (even cracks), the ceramic body of the tile is not fully calcined, the wear resistance is poor, and the flexural strength is low The water absorption rate will also be higher, and such vitrified tiles are highly susceptible to contamination.



The fourth point: fight

The same specifications and models of the product can be randomly taken out of the four , for patching, through this step you can check the tile size, flatness, straight angle and other aspects of the three issues.

(1 ) Check the size of the tiles

Take two pieces of the same type of product and take it on the same horizontal plane with the sides close together. Slide the tip of the hand back and forth along the edge of the tile, if there is no obvious in the tile-jointed seam. The feeling of hand-lagging indicates that the size of the tile is better and the error is small. The smaller the tile size error is, the better the tile effect will be. On the contrary, if there is a significant sense of delaying hand tiles, indicating that the tile size error is larger, it will affect the effect of paving.

(2 ) Check the flatness of the tiles

Two or four tiles of the same type are tiled in the same plane (preferably on the surface of the glass) in the same line, and slide back and forth on the brick surface by hand. If there is no obvious sense of height between the tiles, This shows that the flatness of the tiles is good. On the contrary, it indicates that the flatness of the tiles is poor, which will affect the overall effect of the tiles. If the floor tiles are poorly flat, serious situations will trip over people, so this should attract attention.

(3 ) The question of the straight angle of the tile

Tiles are still mainly rectangular, and each corner of the tile is a right angle. If the angle is straight, it will also affect the tile effect. Take four pieces of the same type of bricks for splicing. If there are four pieces of tiles that cannot be tightly seamed, there will always be gaps in one or two seams, indicating that the straightness of the tiles is not particularly good.



The fifth point: test

As long as it is based on the anti-skid problem of floor tiles, the material is mainly divided into two kinds of vitrified and glazed. For the anti-slip problem of current tiles, everyone's current practice is to add water to the brick surface and then step on it. , to see if it is slippery, this practice is not entirely appropriate, because some tiles, especially glass tiles, add water, it will feel more astringent, this principle is somewhat similar to add water between the glass, if you want to The glass was opened and it was difficult to find, because the water squeezed out the air in the middle, making the bricks and the upper contact more closely, so it felt more involved, and some glass tiles felt slippery when they did not add water. My personal suggestion is to try both water and not water.


B. Paving process of ceramic tiles

1. The cement used for cementing kitchen tiles is No. 425 cement. The proportion of cement sand should not be greater than 1 : 1 . If the cement content is too heavy, the cracking of the tiles will be caused by the high expansion coefficient of the cement and the service life of the tiles will be reduced. .

2. The glazed wall tiles of kitchen and kitchen If cement mortar is used as the adhesive, the tiles need to be covered with water after soaking. The time for soaking the water is appropriate after the tiles are completely immersed and does not take bubbles. Generally, it is 30 minutes. That's it.

3 , paving kitchen tiles whether it belongs to a seamless brick, you must leave the seam, it is recommended not less than 1mm , ordinary wall tiles to 1.5-2mm is appropriate, antique brick gap can be appropriately widened.

4. The paving height of kitchen tiles should be higher than that of ceilings, generally not less than 10 cm .

5. Pay attention to the texture of the tile when paving the tile, do it along the texture, and pay attention to the direction of the tile waistline in the opposite direction. Do not stick it down. At the same time, the texture of the waistline is consistent with the texture of the tile.

6. Stitching should be done after the tiles are solidified. It is usually carried out after 24 hours.

7 , after the ground tile is finished, you must wait for the ground to dry before walking around the brick or other kitchen and bathroom renovation projects.

8 , after the tile to be checked, if it is found that there is an empty drum is the best place to repair the patch.

9 , wall punching needs attention, it is best to punch in the hole where the water spray for cooling treatment, to prevent the tile due to local short-term dramatic temperature changes caused by the tile burst.

10. When drilling a hole in the wall, be sure to check if there is any empty drum. Also, check the pipeline diagram of the hydropower reform that has been retained and do not hit the pipeline.
