What to do if there is a hollow drum and black seams in home decoration tiles

Knock it off and re-pave it, it doesn't matter, you find the construction party and let them be responsible, it will generally be rectified, don't worry.

It is worth noting that if there is a hollow drum phenomenon, how to construct the sewing agent? Simple can be tile compacting, directly start with the beauty of the sewing agent, note that this is generally the hollow drum phenomenon is relatively slight but when there is a sound, in order to prevent the situation from expanding a remedial measure, if the hollow drum phenomenon is too serious, the whole tile will fall, it is necessary to shovel down the tile and re-pave and then carry out the beauty seam construction.

What is hollow drumming?

The "hollowing phenomenon" generally refers to the hollowing phenomenon between the floor, wall, ceiling decoration layer (plastering or pasting surface bricks) and the structural layer (concrete or brick wall) of the house due to the unstable pasting and combination, commonly known as "two-layer skin".

How to determine a hollow drum.

To determine the hollow drum, it is natural to use the hollow drum artifact - the hollow drum hammer.

Here I found a phenomenon that many owners really use the method of knocking to determine whether the drum is empty. Especially those owners who use small bricks, after inspecting a wall, tired and dizzy. In fact, as long as you use a hollow drum hammer to scratch along the surface of the brick, you can naturally judge whether there is a hollow drum from the sound.

How to prevent hollowing?

Originally, I always thought that only big bricks should pay attention to hollow drums, so many friends walked big bricks, and some even used back hooks. However, it should be pointed out here that the use of back hooks is only to ensure that the bricks do not fall off, but not to ensure that the drum does not hollow.

In fact, the empty drum has now been deified by the decoration company, and it should be noted that the empty drum is not the same as dropping. And the purpose of our tiles is not to have no hollow drums, but to be neat and good-looking without falling.

Of course, as the owner's pursuit of 100% perfection is never exaggerated, and I always hope that the tiles of my new home will not be hollow.

However, it is necessary to realize that hollow drums are actually an inevitable result of different materials (red bricks, concrete, tiles) glued together, but have different physical properties (the most important is thermal expansion and cold contraction), an irresistible natural law.

The hollow drum of marble will be even more powerful, I don't believe you will knock on the marble at home in a month or two, almost 99% of it will be empty.

It can be cut out by a tile cutter and then grouted. Re-installation also requires cutting and leaving seams, otherwise the shrinkage will bulge again due to temperature changes.

When the floor tiles are paved, there is no reservation for expansion joints, once the drum is hollow, it can only be lifted up and re-paved to solve the problem.

Then the hollow floor tiles can only be dismantled and resurfaced.

After doing the perfect seam, you find that the tile has a hollow drum Hello dear, use a small hammer to gently tap the brick on the plane, when you hear the clattering, relatively hollow sound, it proves that the tile has a hollow drum phenomenon, the wall tile hollow drum may cause falling off, bringing potential safety hazards, and the floor tile hollow drum will lead to arching and warping, which is detrimental to the appearance. For the difference in the area of the hollow drum, we can do different treatment. If you find that there is a hollow drum on the edge of the tile, you can water the round part of the edge hollow drum (smash the gap between the tiles with a small shovel to cultivate dust, and then pour the cement with water into the gap, and the hollow drum will automatically suck it in until it is filled and solidified), and avoid overall replacement.

A small amount of local hollowing of the tiles on the wall and floor, such as without affecting the cabinets, mirror cabinets, showers and water heaters and other furniture and household appliances installed firmly, can not be treated, but if it affects the installation and daily life, it is recommended to knock off the local tiles and re-pave. 2 3 area hollow drum It is recommended to remove it and re-pave, at this time the adhesive used in paving is particularly important, if the tile area is small, you can use the adhesive cement, which is stronger than cement; A single tile is pasted on a flat plane, you can use tile adhesive tile adhesive, if it is a small area of multiple tiles, it is recommended to use cement is more appropriate than the use of cement. Hope it helps.

If there is a hollowing after tile caulking, you can consider the following solutions:

1.Reinstallation: If the area where the excavation is hollowed out is large, or if the gap is filled with more cement or tile adhesive, it is recommended to reinstall the tile to ensure that the tile can be firmly attached to the floor or wall.

2.Re-caulking: If the area of the cavity is not large, you can re-judge the new filling gap and use the appropriate caulking material to ensure that the hollow part can be filled when the caulking is completed, so that the tile can be firmly fixed to the floor or wall.

3.Reinforcement: If you don't want to reinstall or recaulk, consider reinforcing it. After filling the gaps, use a special tile reinforcing agent to reinforce the hollow parts to increase the adhesion of the tiles as much as possible.

Please note that for the treatment of tile hollowing problems, it is recommended to choose a professional worker or company to solve it to ensure the quality and effect of the whole process.

There are two main methods for the repair of tile hollows, one is grouting and the other is re-paving.

If it is due to the hollow drum tile is not reliable and can be removed, you can first scrape the mortar adhered to the back of the tile and around it, and then mix a little cement with 107 glue to stir it into a paste, evenly coat a thin layer on the back of the tile, and then press the tile, and it will stick firmly after a few hours.

Take a small hammer and hit the tile, if you hear a hollow sound and destroy it, it means that the tile has been hollowed. However, the tile is relatively firm and difficult to remove, so it can be remedied by grouting method. It is to mix the mortar evenly, and pour the mortar into the hollow place with a finer scraper in the gap between the tiles.

Pour and tap until you sound solid.

The best remedy for tile hollowing:

1. If there is a hollow drum in the corner of the tile, you can use a small shovel to smash the gap between the tiles, and then pour the prepared cement into the gap until the gap is filled and solidified.

2. If the dust of a single tile pin is hollow, you can clean up the filler around the tile, and then take out the tile, clean up the paste layer on the surface, and re-pave.

3. For the linearity of the large area of hollow tiles, all the tiles need to be removed and re-paved with new tiles.

Corner hollow drums, hollow drums in the middle of tiles, large area hollow drums, hollow drums fall off, the degree is lighter, and the repair methods are different for different hollow drums.

1. Hollow corners

Scrape the tile gap at the corner hollow drum, and then mix the cement into a very thin and dilute cement slurry, while hitting the hollow drum with a metal hammer to make it vibrate, and at the same time pour cement slurry from the gap, so that the cement slurry gradually fills the hollow drum. After the cement slurry solidifies and solidifies, re-test whether the tiles continue to be hollow.

2. The middle part of the tile is hollow

You can choose to use a suction cup to suck the hollow drum tile, hang it straight out, and then re-install the hollow drum tile according to the specification. Another way is to smash the tiles apart from the middle, using a crowbar, and carefully pry the damaged tiles from the middle to the sides until the tiles are completely loose. This treatment will not cause damage to the surrounding tiles.

After removing the tiles, continue to re-apply them according to the specifications.

3. Large-area hollow drum

If there are hollows in more than 1 3 pavement areas, it is necessary to pry off all the tiles on the whole surface and re-pavement. Generally speaking, this large-area hollowing drum is generally caused by improper construction, and the construction party should bear the cost of tile damage and labor accessories. At this time, it is necessary to take out all the bricks, chisel the cement layer of the wall and floor, and then redo the base layer and then lay the tiles.

4. The hollow drum falls off

If the degree of hollowing is more serious, the empty, the tile has been completely loosened or even falling off, indicating that the cement mortar layer under the tile and the wall base (or ground base) have also been loosened "delamination", at this time, the cement mortar layer can be cleaned up with a tool, and the tile is paved after re-applying the cement mortar.

5. The degree is lighter and the position is more biased

If the tiles on the wall and floor appear to be slightly hollow, but do not affect the installation of cabinets, mirror cabinets, showers and water heaters, etc., the location is also behind the cabinets and other furniture.
