The phenomenon of hollow ceramic tiles often occurs. Sometimes the phenomenon of hollow ceramic tiles also occurs when the decoration is not up to standard. However, many people do not understand this, so let’s take a look at today’s topic. How are the hollows on the tile floor formed? Let’s take a look at the treatment methods!
1. What are the causes of hollow ceramic tiles
1. Hollows caused by insufficient bonding between the base layer and the dry hard mortar
The main reason for hollowing is that the base layer is not properly treated. The smooth base surface and floor must be chiseled. The chisel depth is 5---10mm and the spacing is 30mm. The surface of the ground base must be cleaned and the surface Clean the remaining slurry, dust and oil stains with a wire brush, and rinse the floor with water. In addition, the grout should be swept evenly on the surface of the base layer. Because the mortar has uneven consistency and thickness, it is easy to cause uneven shrinkage during the setting process, thus affecting the bonding effect.
2. The bonding between the plate surface layer and the dry hard mortar bonding layer is not strong, resulting in hollowing
The main reason for this phenomenon is that people walk on the floor tiles and hard mortar before they are dry. The bonding strength of the newly laid tiles is not enough, so construction management should be strengthened to prevent people from walking on them. In addition, if the back of the ceramic tile is not cleaned cleanly and there are too many debris, it may affect the adhesion. Ceramic tiles with water absorption must be soaked in water in advance.
3. Improper laying method causes hollowing in the four corners of the tiles
When laying ceramic tiles, if the four corners are not on the mortar surface at the same time but one corner is on the mortar surface first, local stress will inevitably be exerted on this corner. As a result, the mortar surface is pressed into a pit, and hollowing occurs because the mortar is not full. Especially when the brick area is large, more attention should be paid to the laying method. The tiles should avoid partial contact with the ground, and the cement mortar surface must be smooth.
2. How to deal with hollowing in ceramic tiles
1. Scrape the gaps between the ceramic tiles at the corners of the hollows, and then mix the cement into a very thin grout. Use a metal hammer to hit the hollows to make them vibrate, and pour water from the gaps. Mud, so that the cement slurry gradually fills the hollow area. After the cement slurry has solidified, recheck whether the tiles continue to hollow.
2. There is a hollow in the middle of the tile, or there is a hole in one brick.If there are more than three hollow points, it is recommended to remove the whole piece, choose to use a suction cup to suck the tiles, lift them out straight, clean the original bottom mortar, and then re-pave the tiles according to the standard process.
3. If a large area of hollowing is caused by improper construction, the construction party should bear the cost of tile damage and labor and auxiliary materials. At this time, it is necessary to take out all the fixed bricks, cut out the cement layer on the wall and floor, redo the base layer, and then lay the ceramic tiles.
