At the time, when the tiles were laid, they only thought that the gap was as small as possible, but they ignored the natural laws of thermal expansion and contraction. After Mr. Hu spent 5 years in the room, he had to face the ceramic tile suddenly arched in the middle of the living room. What should he do? All repaving? The price is too great; knock out the bulging tiles and re-paving? For too long, no bricks of the same color could be found. I believe that many decoration friends have encountered this thorny problem.
Owner Readme
My home was renovated five years ago. At that time, 800mm×800mm large bricks were selected for the living room. The brightness of this brick is high, and the smaller the gap, the better. At that time, the decoration workers also told us that the brick seams should not be too small, otherwise they would be prone to problems. However, at that time we did not understand, but only thought that the gap was small and nice. The workers laid out according to our requirements. After the shop was finished, the crevices were small and the brick surface was very clean and beautiful. Many neighbors came to my house and praised my bricks for being well laid. Unexpectedly, on the second day of stopping heating this spring, the bricks in the middle of the living room suddenly appeared arching, and they were getting worse and worse. We pondered that it may have something to do with stopping the heating. Moreover, in 2003 my family once flooded the water once. It was very serious. I don't know if the tile is now arched and it has nothing to do with the water.
Reporters witnessed
Arched tiles
Once inside, the reporter discovered that the tiles in front were not quite right. Some of them were not smooth. The more they walked into the living room, the more the tiles arched, the more the two tiles inside were separated from the tiles next to them. Arched tile edge. Mr. Hu’s family came and went carefully around these tiles, “fear of accidentally cracking.†The reporter tapped the arched tile with his fingers and could clearly hear the sound of empty drums.
Analysis of Causes of Floor Tile Arching
There are roughly the following reasons
One is that the expansion and contraction gap reserved between floor tiles and floor tiles and between floor tiles and surrounding walls is too narrow! When the room temperature changes drastically, the floor, the cement layer and the tile will appear thermal expansion and contraction phenomenon, such as the gap is too fine, there is not enough space for the tiles to "stretch", the tiles will be easy to arch, which is easy to appear in the northern region, the South Because the humidity is relatively large, the temperature difference is small and it is not easy to appear.
The second is that when the paving tiles were not blended with cement and sand in the correct proportion. If the cement number is low and the yellow sand is placed in a lot, over time, the underlying cement will not be able to adhere to the floor tile, causing the floor tile to curl up.
There is also a relatively rare reason that if the original concrete floor is very smooth and tiled without being roughed, tile arching is also prone to occur.
Method for solving tile arching
Check to see if individual tiles are arching or arching over large areas. You can use tapping tiles, the sound of empty tiles is already empty, that is, the tiles have been separated from the cement layer, such tiles as barely pressed down, it is easy to break. Therefore, the arched tiles must be picked up and repaved. If there are a large number of empty tiles, they will simply be repaved.
Re-tiling Notes
1. The joints between the arched tiles and other tiles are sawn with a cutting machine (there will be a lot of dust when cutting, need to constantly add water to the cutting machine.), carefully lift the tiles, the action must be Be light, otherwise it will easily cause the tiles to crack.
2. Scrape all the cement mortar sticking on the edge of the tile. Treat the cement layer under the brick, shave 1-2 cm and clean it.
3. Apply evenly a layer of mixed cement mortar. The proportion of cement yellow sand is: 1:3 for wall tiles, 1:2 – 3 for floor tiles, and 32.5 for cement. In addition, if you are using white cement, you must use 108 glue, which can make the cement and the floor tile close adhesion.
4. Lay the cleaned tiles and flatten them. After the cement is completely dry, use a caulking machine to reinforce the tiles. This prevents the tiles from being upturned and cracked.
