What is the remedy for the large area of hollow wall tiles in the bathroom in addition to repasting?

In addition to the solution of repasting, the large-area hollow drum of bathroom wall tiles is: you can choose to use the method of grouting, mix the cement and some additional glue substances into a slurry-like material, and use tools to slowly grout the back of the tile. Realize the effective remedy of the hollow parts of the tiles.

In fact, the method of glue injection and grouting in the hollow drum part of the tile is almost the same. However, glue injection can only be poured to the edge of the tile, that is to say, it is good to use the method of glue injection to solve the problem after the hollowing of the edge of the tile. The most commonly used can use special glue for marble, that is, AB two-component glue.

You can use a glue gun to slowly pour glue into the tile joints.

Strictly inspect the base layer of the wall surface where the tiles are pasted. All the sand and hollowing on the wall must be treated and then pasted with the tiles on the wall. When the wall tiles are sole, they must be paved according to the requirements of the tiles. It is not allowed to apply tiles to the wall by means of seamless paving.

Empty drum reason:

First, the expansion gap between the floor tiles and the floor tiles and the surrounding walls is too narrow, and when the room temperature changes drastically, the floor, cement layer and ceramic tiles will appear thermal expansion and cold contraction. If the gap is too thin and there is not enough space for the tile to "stretch", the tile is easy to arch, which is generally easy to appear in the northern region, while the south is not easy to appear due to the high humidity and small temperature difference.

The second is that the cement and yellow sand are not mixed in the correct proportion when laying the floor tiles. 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.

Another relatively rare reason is that if the original cement floor is very smooth, it is easy to arch the tiles without hairing.

Solution: First check the floor tiles in the entire store or room to see whether individual tiles are arched or large areas. 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, re-pavement, and if there are a large number of hollow tiles, they should simply be re-paved in their entirety.

First, the joint between the arched tile and other tiles is sawed with a cutting machine (there will be a lot of dust when cutting, so you need to keep adding water to the cutting machine), you should be very careful to 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.

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

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

Fourth, the cleaned tiles are re-paved, flattened, and then reinforced with a caulking machine after the cement is completely dry, so as to avoid the phenomenon of upturned and cracking of the floor tiles.

There's no way, the next time you post it, you have to go to the construction site often, and you can't be lazy.

No, it must be all eradicated. Pay attention to the seam when repasting.

No way, no one can fill it up through the wall, so let's re-paste it.

At present, the level of science and technology is only repasted, and the wall is not brushed, and workers must be allowed to do brushing when pasting.
