Who knows what to do with the arching of floor tiles during decoration

This is some of the information I found on the Wuhan Home Improvement ** Internet, if you still have some questions about decoration, you can check it, you should be able to find out what you need to know. The following is for reference only:

First, if the floor tiles are all arched, one by one can be taken down by hand, then write each brick with a number - so that it is convenient to remember the original position, keep the original direction of the floor tiles unchanged - and then scrape off all the cement mortar stuck to the side of the tiles.

The cement mortar on the bottom surface of the original surface is wiped clean with a dry rag, and then the bottom surface is coated with white glue for carpentry, and then compacted according to the number. To repair a square meter of floor tiles, it is about a pound of white glue.

Second, if only part of the arch up, there are some floor tiles that can be taken down directly, and some can not be taken down, and the floor tiles that cannot be taken can not be pryed, and the hard pry floor tiles are broken, which is more troublesome and requires a cutting machine.

The cutting machine cuts along the floor tile joint, a brick has four sides, and several need to be cut depending on the specific situation, some are afraid that all four sides will be cut, and some can cut two sides.

After cutting, it usually takes an hour or two for the arched floor tiles to collapse naturally. There is a lot of dust when cutting, and you need to constantly add water to the cutter.

There is basically no way to deal with the arching, especially the middle arching.

Generally speaking, if the edge of the paving is uneven, you can also use heavy pressure to smooth the joint.

Therefore, when buying bricks, you should pay special attention to the quality and brand value of bricks. Of course, some brands of good bricks will also have arching, such as Dongpeng, which has good hardness and flatness.

If you want it to work well, you can only redo it!

<>1. Check the floor tiles in the entire store or room to see whether individual tiles are arched or large-scale arches. When inspecting, you can use to tap the tile, if the sound is empty, it is already hollow, that is, the tile has been separated from the cement layer. Such tiles can easily crack if they are barely pressed down.

Therefore, it is necessary to pry up the arched tiles and re-pave, and if the number of tiles is large, they can simply be resurfaced.

2. First cut the joints between the arched tiles and other tiles with a cutting machine (there will be a lot of dust when cutting, so you need to keep adding water to the cutting machine), and you should lift the tiles very carefully, and the action must be light, otherwise it is easy to cause the tile to crack.

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

3. Floor tiles: 1:2 - 3, the cement number of cement is cement.

In addition, if you use white water to check the collapse of the ridge mud, be sure to use 108 glue, so that the cement and the floor tiles can be tightly bonded.

5. 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 upturning, cracking and seepage of the floor tiles.

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.

Why do the floor tiles arch over time.

There are generally two situations in which the floor tile arch is raised, one is that there is a problem in the construction process, and the other is caused by the thermal expansion and contraction before the floor tiles are paved in order to leave enough gaps.

Re-laying, the brick joint leaves a shrinkage joint of 2 to 3 mm, which can play a balancing role in relieving thermal expansion and cold contraction, and prevent arching.

In this case, it can only be repaved, and it is recommended that it is best to go on **.
