What is the cause of the hollowing of tiles after waterproofing in the bathroom?

The reason for the hollowing of tile adhesive.

1.The ground is uneven and unclean.

If the ground is not flat enough, or there are foreign objects that are not cleaned up, the tile and the ground are not completely fitted, resulting in the later hollowing. In addition, the lack of cleanliness of the floor will also affect the adhesion of the adhesive, which will cause the tile to hollow even if the floor is flat enough.

2.Stirring is not sufficient.

Only sufficient stirring can make the adhesive inside fully fused to exert the maximum adhesion, if not fully stirred will make the adhesion of the mortar decrease, resulting in the later stage of the tile hollowing situation.

3.Tile adhesive soaked in water.

In the early stage, many construction personnel who are in contact with the ratio mortar or tile adhesive will have a lot of misunderstandings, and will use the traditional method of soaking cement according to their own experience, and soak the ratio of the stirred tile adhesive in the bucket, afraid that the material will dry too quickly, if this will lead to the water absorption of the tile adhesive is too high, weakening the strength of the paste, causing chalking, and the tile will be easy to fall off.

4.Too long after stirring.

After the tile adhesive is stirred to a certain extent, it will begin to have a chemical reaction to produce adhesion force, which is generally a good time to use within two hours after stirring, and must be used in time at this time, do not think that you can continue to add water to stir to prolong the effective aging.

1. Corner hollowing remedy: If the corner of the bathroom wall tile is hollow, the gap around the wall tile must be shoveled, and the relatively thin cement should be used for pouring and tapping the tile while pouring, so that the cement slurry can be completely penetrated. This treatment saves time and effort, and is not easy to cause damage to the tiles.

2. Remedy for hollowing in the middle: If there is a hollowing in the middle of the tile, it is necessary to pry the tile off and re-lay it. Specifically, it is necessary to smash from the middle part of the tile, but not directly from the middle, you can use a small rhinestone to open a hole first, and then use a tool to slowly spread to the surrounding way to pry open the tile, to avoid damage to the surrounding tiles.

3. Large-area hollow drum remedy: If there is a hollow drum in the pavement area of more than 1 3, it is necessary to pry off all the tiles on the whole surface and re-pavement. Usually this large-area hollowing drum is caused by improper construction, and the construction party should bear the cost of tile damage and labor accessories.

The main reason is that the mortar is not full or the tile is not gently beaten and squeezed densely when the tile is paved; The tiles are not soaked in water or soaked enough before they are laid; The plastering of the wall base is not treated as required or the base is not cleaned.

There are two reasons for the hollowing of bathroom tiles, one is related to the operator, the paste is not dense, and the ash area is not comprehensive when the tile is paved. The second is that the pasting material is unqualified, and there is no firm pasting of tiles and walls.

After the bathroom is waterproofed, the tile is hollow, which is caused by the fact that the tile master is not full of hollows formed in the cement when he is working.

After the bathroom is waterproofed, there will be a hollowing phenomenon when the tiles are pasted up. Because of the waterproof material, that is, one of its densities is very high, and then the tile is pasted, the adhesion may not be so high, so there will be a hollow drum.

What is the cause of the hollow kitchen bricks after the bathroom is waterproof? If the tile is hollow after the bathroom is waterproof, it should be the reason why there was no mason who did not paste it well when the tile was pasted, and it was not implemented.

The bathroom is waterproof, and the tiles are hollow, which is caused by the lack of cement when the tiles are pasted.

There are many reasons for the hollowing of tiles, such as the wrong proportion of mortar glue, the lack of water soaking in tiles, the rough treatment of the wall base, and the level of bricklayers is too bad, the mortar is not evenly smeared, and there is no mud at all at the corners of the tiles, and it will fall off after a long time.

Kitchen and bathroom tiles hollowing reasons: non-standard wall base plastering is not treated as required or the base garbage is not cleaned up. Before tile paving, check whether the plastering of the wall base meets the requirements, and the wall base debris, dust and must be cleaned; When paving, the back of the tile is covered with cement mixed mortar or 107 cement slurry and taps the tile with a hammer handle or soft hammer to make the cement grout crowd the back of the tile, and then press hard to make the tile firmly combined with the wall base.

Not soaked in water before paving or not soaked enough. Tiles (especially glazed tiles) should be soaked in water for more than 2 hours before paving, so that the tiles can fully absorb water, and then take out the shade to dry or wipe the clear water. If the brick is not saturated with water, it will absorb the water in the mortar prematurely, resulting in the mortar shrinkage and hollowing, and it will also affect the strength of the paste.

Not full: When the tile is paved, the mortar is not full, or the tile is not gently beaten and squeezed densely. It's a case of either cutting corners or cutting corners: to save cement mortar, or to save time.

There is another situation that mostly occurs when contracting labor and materials, that is, the quality of the tiles is too poor, and I am afraid that the tiles will be broken when tamping. Solution: First take out the hollow drum tile, and then clean the base layer and the back of the tile, it is recommended to use fast and good anti-mildew super sealing structural adhesive or use fast and good strong liquid nail 300ml on the back of the tile, using multi-point distribution as well.

Finally, level with a rubber hammer. It is recommended to use ExxBox's caulk 2KG for hook joints. Construction Method:

1.Base surface treatment: Remove oil, dust and loose objects from the work surface, clean tile crevices, and ensure that there is no debris and water accumulation.

2.Stirring: Pour the dry powder into a container filled with 27% 29% water in a certain proportion, stir at low speed with an electric mixer, stir while pouring the powder until the thick slurry (like paste) with no granulation and precipitation is uniform and free of granulation and precipitation, and then stir for 1 2 minutes before use.

3.Caulking: Use a professional caulking tool to completely press the caulk into the gap diagonally, taking care not to leave it empty.

After 10 minutes, wipe off the caulk from the tile surface with a damp sponge or cloth. 4.Cleaning:

After the caulk is dry, use a wrung out wet sponge to clean the surface of the tile. Try to avoid strong direct sunlight for 3 days after construction, and it is recommended to sprinkle and maintain the construction of the caulking material every day for a week.

Hello, it may be that the underlying base layer was not treated well when tiling, which destroyed the waterproof layer.
