What should I do if the tiles of the kitchen flue fall off?

Decoration is really a big project, whether it is to buy materials or the process of decoration is to make people feel more tired, just like a few days ago there is a relative in the decoration, I went with him to see the construction site, and then I saw the workers in the flue construction again, after the inquiry, I knew that it was because the kitchen flue tiles fell off, in the repair.

> one of the masters with 20 years of experience told us that like this kind of tile falling, we must first understand the reason for the tile falling off, to see if it is because of the hollow drum caused by the tile falling off, the viewing method is to carry out a gentle knock on the tile that has not fallen off, through the percussion sound to judge whether the tile has a hollow drum phenomenon, if it is a "knock knock" louder sound, it feels very likely to be a hollow drum, if the sound is relatively low and dull, the tile is more firm.

A large part of the > hollowing phenomenon is due to the fact that the master's manual craftsmanship is not in place during the construction process, of course, there may be improper material ratio of cement mortar, poor quality of ceramic tiles or insufficient water absorption and other reasons, the main manifestation is that there is a gap between the tile and the wall, which can not be completely pasted, resulting in the tile slowly falling off after various high temperature and dry environments.

> if this happens, if you can, it is best to remove the tiles in the flue now and let the workers re-construct, you can also use nail-free glue to paint the two sides of the tile, let it dry for a while and then fix the tile, this method is more suitable for the repair of a small area of tile falling off, the cost is relatively fast and the price is low, but it is not suitable for the whole flue, if it falls off more, it is re-pasted with cement mortar.

> if there is no hollowing of the flue tile, you can check whether the tile falls off due to the cracking of the tile gap, you can use grout to refill the joint, and you can also use mildew-proof neutral silicone to coat the gap. It may also be caused by workers cutting corners, before tiling the flue should be reinforced with barbed wire to reduce the problem of falling off caused by the instability of the bottom layer of the tile, and you can also follow the advice of the worker to wrap a layer of bricks in the flue.

Be sure to do waterproof treatment on the flue, brush it several times, and let the flue not suck any water at all, so that it can be managed for a long time.

If the drum is hollow, it is best to remove the current tile, apply both sides with nail-free glue, and fix it again when it is not sticky. Or ask the worker to re-paste, in order to avoid hollowing and cracks, you can try to paste the tile paste, and the final caulking is the same as below; If it is not hollow, but only the grout cracks, use a tool such as a blade to remove the grout, buy an anti-mildew grout to refill the joint, or use anti-mildew neutral silicone to coat the gap.

The most common reason for the tile falling off at the kitchen flue is that the tile is paved with a hollow drum, and the following factors lead to the hollow drum

1. The brushing layer of the kitchen flue base layer appears hollow and delamination, which then affects the firm bonding of subsequent tiles;

2. When the tile is paved, the tile that needs to be soaked in water is not fully soaked in water or the time is too long after soaking in water, resulting in the volatilization of water in the brick, and after the cement mortar is applied at the bottom, the tile embryo absorbs the water in the brick body too quickly, thereby shortening the natural solidification cycle of the cement mortar, thereby reducing the bonding effectiveness of the cement mortar, resulting in the loosening and falling off of the tile;

3. When pasting tiles, the cement mortar on the back of the brick is unevenly smeared, resulting in hollowing, which leads to the loosening and falling off of the tile;

4. The tile is hooked before it is dried and solidified, so as to artificially cause the tile to loosen;

5. The tile paving and leaving joints are too narrow.
