Supervisor does not know how to read tile tiles

The decoration and tiling is a project that must be carried out by each owner in the pre-decoration period. However, as most of the owners do not know much about tile knowledge, the masters of the tiled workers are incapable of supervising and irregular operations often occur, causing hidden dangers in decoration and inconvenience to future life. Therefore, today we have brought you a tile-laying process that will allow you to “justify” the construction supervision.

Tiles must be left seamed when paving. Whether the tiles are "seamless bricks" or "round-edged bricks" are required to leave the seams!

(1) Thermal expansion and contraction of ceramic tiles

Tiles and tiled cement mortars have thermal expansion and contraction problems. In the process of changing temperature or humidity, ceramic tile and cement mortar will have a certain degree of expansion and contraction. If no joints are left, it will lead to the use of ceramic tiles in later use. Drums or cracks appear

(2) Tiles have errors

Although ceramic tiles are now produced mechanically, there are certain dimensional errors in the process of product production. (If the error is too large, it belongs to the quality of the product.) If no seams are left, it will easily appear when the ceramic tile is tiled. Uneven seams affect the aesthetic appearance of the tiles.

(3) Construction workers have errors in construction

The paving of ceramic tile is a construction project with a high level of proficiency. During the entire process of paving, workers can not completely complete the installation of each tile without errors. The workers are in a bad mood, day and night, etc. Tiles that are tiled under different conditions will have different effects. If you do not leave seams, it is also difficult to ensure that the seams of the tiles are straight and affect the aesthetic appearance of the tiles.

  

(1) waterproof bathroom

The wall of the bathroom is waterproof. This is a construction project that must be carried out in accordance with the requirements of the code. Waterproofing will not only damage the outer walls, floors, wooden doors and other items of the bathroom, but also affect the downstairs.

(2) wall surface treatment

The method of wall covering is to use cementitious mortar or cement mortar (the content of sand is not too high) to treat the wall surface into a jagged and jagged joint layer. After the wall surface is roughened, the surface area of ​​the wall surface is increased, which is effective. Increase the contact area between the tile and the wall, thus effectively increasing the bonding strength between the tile and the wall.

(3) Tile water treatment

Soaking water treatment, soaking water is to fully absorb the glazed tiles process, because of its water absorption rate of about 10%, no soaking water will cause the mortar in the water instantly absorbed by the tiles, resulting in decreased adhesion, easy to emptying, Fall off. Because the water absorption rate of vitrified tiles is less than 0.5%, it is basically equivalent to no water absorption, so there is no difference between soaking water and soaking water! When paving tiles, do not need to soak, directly paving!

  

Tiles for jointing treatment, generally dry after the tile is appropriate, if the tile is not completely dry on the hook, the problems are: First, causing the tile uneven, and second, causing the tiles to loosen, so that When used later, the tiles can easily come off; in general, the time of the jointing is better when the tiles are tiled for 24 hours.

When performing the jointing of tiles, first of all need to clean up the dust and impurities in the tiles, then squeeze the grout into the brick seams, pay attention to the time of filling, be sure to squeeze full fill, after the jointing, timely Clean up the seaming material on the brick surface!

  

In general, the current paving of floor tiles is basically a dry paving method.

Dry shop method: Wet the grass roots, remove floating sand, debris, wipe the combined layer, and soak the bricks. Use one to three dry hard cement mortar. Spread and lay flat along the horizontal line. Place the bricks soaked in water. The cement is beaten with a sponge, the bubbles in the cement are squeezed out to take the bottom brick, and a thin pure grout is put on the back of the brick. The tile can be put down and leveled, and the grout can be dried with this layer of grout. Hard cement mortar bases are completely bonded together. The advantage of the dry paving method is that the paved brick surface is smooth and there is less hollowing.

  

1. Entrance door: When designing a brick project, use the center of the entrance door as the base line to start arranging tiles on both sides.

2. Aisle: Start with the centerline of the aisle and start paving on both sides.

3, the length and width of the living room: the long side or wide edge of the living room, the tile for the whole piece of the effect is better, if there is a non-integral formation of a column, the width of non-entire tiles should be greater than the width of the tile More than half is appropriate.

The practice of the decoration company or construction party is to lay the wall tiles first, then to lay the floor tiles, to put the wall tiles on the tile, and not to affect the wall tiles or delay the construction period.

  

In the space, the raised corner is the angle of the sun, and the recessed corner is the inside corner. In the process of laying tiles, two common practices when dealing with sunken corners are:

(1) When using the angle line, when using the angle line to deal with the angle, the construction is relatively simple and convenient. The problem to be paid attention to is that the angle line on the market is mostly made of PVC material, and the material itself and the ceramic tile The color is difficult to be consistent, and whether or not the coordination effect is satisfactory needs to be measured by oneself. At the same time, after this material is used for a long time, it is easy to turn yellow and affect the appearance. In addition, the market also has a new type of aluminum alloy, which is not easy to change color. ;

(2) The unilateral backside of the ceramic tiles on both sides of the corners is inverted at an angle of 45°. The advantage of this treatment is that it can effectively make the overall wall more consistent and unified, but in the construction process, when the back of the brick is cut at an angle of 45°, do not fall too thin, which will easily damage the glaze on the surface of the tile. In the late stage, the problem of cracking of the tile at the seam of the male corner is likely to occur.

  

Wall sand and floor tiles are generally used in river sand and sand can be selected. For sand and floor tiles, sand is the same as sand used in the river sand. When the wall tiles and floor tiles are tiled, the content ratio of the cement may have some differences. Generally, for the floor tiles, the ratio of cement and sand is recommended. For 1:2.5, the ratio of cement sand is 1:3. Paving wall tiles, the proposed cement content should not be too high, and the label can not be too high, the general 325 label home is enough, otherwise in the later use process, it will lead to tile cracking!
