When water enters the living room at minus 8 degrees, will the floor tiles arch up?

1. The reason for the arching of the floor:

1. The expansion gap reserved between the floor tiles and the floor tiles and the surrounding walls is too narrow, when the room temperature changes drastically, the floor, the cement layer and the tiles will appear thermal expansion and cold contraction, such as the gap is too fine, there is not enough space for the tile to "stretch", the tile is easy to arch, which is easy to appear in the northern region, and the south is not easy to appear because of the large humidity and small temperature difference.

2. When laying floor tiles, cement and yellow sand are not mixed in the correct proportion. If the cement grade is low and the yellow sand is put too much, after a long time, the cement in the lower layer will not be able to bond the floor tiles, causing the floor tiles to be upturned.

3. There is a relatively rare reason, if the original cement floor is very smooth, and the tiles are paved without hair, it is also easy to appear that the tiles are arched.

Second, the solution.

Check whether it is an individual tile arch or a large area of arching. You can use the knock tile, the sound of the empty tile is already hollow, that is, the tile has been separated from the cement layer, such a tile is easy to crack if it is barely pressed. Therefore, it is necessary to pry up the arched tiles, re-pavement, and if there are a large number of hollow tiles, they should simply be re-paved in their entirety.

Third, the precautions for tile repaving.

1.The joints between the arched tiles and other tiles are sawn with a cutter (there will be a lot of dust when cutting, and you need to constantly add water to the cutter. Carefully lift the tile, the action must be light, otherwise it is easy to cause the tile to crack.

2.Scrape off all the cement mortar that sticks to the edge of the tile. Treat the cement layer under the bricks, plane off 1-2 cm and clean it up.

Wall tiles 1:3, floor tiles: 1:

2-3, the cement number of cement is the number of cement. In addition, if white cement is used, be sure to use 108 glue, which can make the cement and floor tiles tightly bonded.

4.Re-pave and flatten the cleaned tiles, and then use a caulking machine to reinforce the cement after the cement is completely dry, so as to avoid the phenomenon of upturned and cracking of the floor tiles.
