1, Tiles to be fully soaked
Before tiling, the tiles should be fully soaked. This is mainly to make the pores in the tiles absorb water. In this way, hollowing and falling are not easy to occur during tiling. If the tiles are not soaked and directly pasted on the wall, it is likely that the tiles will directly absorb the water in the cement. To a certain extent, the tiles will even crack, which will cause A lot of ceramic tiles are wasted, and the quality of tiling is not good.
2, Hanging plumb line before paving
Before paving, the vertical line or infrared ray shall be hung on the wall surface leveling layer to determine the size line of the ceramic tile out of the wall, and the horizontal line shall be drawn, so that the surface can be flat and the ceramic tile can be horizontal and vertical when paving.
3, It is better to place the cutting tiles at the corner of the wall
Cutting ceramic tiles always looks a little uneven, so it's better to put them in the corner of the wall, which can be sealed with sealant at the end, without affecting the decoration effect of the house. If it is placed under the window and other conspicuous places, it will affect the beauty of the house.
4, The position of the first brick must be selected
The position of the first brick determines the position of the tiles in the whole wall, so the position of the first tile must be selected. If the position of the first tile is wrong, the tiles of the whole wall will be crooked. Tiling generally starts from the external corner or door and window edge, and proceeds from bottom to top, from left to right. First wet the leveling layer with water, use a small ash shovel to smear the mixed bonding material on the back of the ceramic tile, then paste the ceramic tile on the wall, and tap the ceramic tile with a wooden handle or rubber hammer of the ash shovel to make the bonding material fill the whole gap between the ceramic tile and the wall, and pay attention to the upper edge of the ceramic tile. The mouth should be aligned with the horizontal line. If it is uneven, small wood pieces can be padded at the bottom of the tiles for adjustment. After a row of tiling, use a guiding rule to level horizontally and horizontally, knock out the higher tiles, remove the concave tiles and paste again.
5, We must press the wall against the ground
The wall pressing is that the wall tiles should be on the floor tiles. The advantage of doing this is that there is no water in the wall. The water drops in the wall will flow along the wall tiles to the floor tile surface, which is easy to clean. Because this is more troublesome, some bricklayers are not willing to do it for various reasons. This is that the decoration owners must supervise the bricklayers and let them do the project well.
6, The excess material in the gap shall be scraped clean
The redundant bonding materials in the ceramic tile joints shall be scraped clean in time, and the stains on the tiles shall be wiped off with wet cotton cloth. Do not wait until the bonding materials are dry and hard to wipe and clean, which will not only fail to clean, but also damage the glaze if it is scraped off with hard objects. After the bonding materials are solidified, the joints can be brushed once with white cement, gypsum mortar or color paste, and the mortar can be wiped evenly and filled with cotton yarn.
7, Precautions after tiling
After one hour of tiling, the cement, joint sealer or other dirty objects left on the brick surface shall be wiped clean in time, because it is difficult to clean after four hours of adhesion of joint sealer. After 12 hours of tiling, the brick surface shall be knocked for inspection, and if there is empty drum sound, it shall be laid again. Walk 24 hours after tile laying. Scrub thoroughly. Mix detergent with clear water to clean tile thoroughly.
Acceptance standard after Tiling:
1. Pay attention to whether the floor tiles need to be tiled or paved in a unified direction.
2. Floor tile hollowing shall be controlled within 3%, hollowing on the main channel must be reworked, 3% refers to single block corner hollowing, and the whole block shall not be hollowed.
3. After the floor tiles are paved, check whether there is any error, hollowing, color difference, etc. in the flatness, use thick cardboard or plywood, old carpet, etc. to cover and protect them. The gap between the boards must be pasted tightly with wide paper tape to prevent sundries from entering.
4. Whether the joints on the brick surface are regular and uniform, the joints are even and tidy, the brick joints are not more than 1mm, and the tile error is not more than 0.8cm.
5. Whether the brick surface is broken and broken.
6. Step on it or knock with a small hammer to see if there is any local noise.
7. See whether the pointing is even and uneven. Pay attention to paving, and wipe the cement in time when pointing.
8. In addition, paving acceptance is related to the quality of ceramic tiles, and the internal cohesion process of cement is not completely completed at the time of paving. It's better to wait 20 days for the cement strength to come up completely before acceptance, and then see if the tiles will crack.
