How much is a square meter of exterior wall tiles, and how to prevent the falling off of exterior wa

There are many varieties of exterior wall tiles: glazed tiles, ceramic tiles, matte bricks, imitation stone bricks, antique bricks, split bricks, printed bricks, and the conventional ones are generally 80-200 yuan per square meter.

How to prevent exterior wall tiles from falling off:

1. When laying tiles, the cement slurry binding layer is required to be evenly painted, and the painting time should not be too long, so as to prevent the air from drying and hardening, resulting in the separation of the surface layer and the base layer, resulting in bulging.

2. Mix mortar strictly according to the ratio, can not add water arbitrarily, mortar should be dry and hard, and the general thickness should be controlled at 2-3 cm.

3. When paving the floor tiles, the floating dust on the back should be cleaned and watered to ensure that they are well bonded.

4. When paving the floor tiles, press the four corners at the same time to make them contact with the mortar parallel to the mortar, and 2-3 cm higher than the pull line, and then hit with a wooden hammer or rubber hammer, and level the face with a level. After laying a piece, it is paved sequentially to the sides or in the backward direction. If it is found that there is a phenomenon of sagging, the tile should be lifted up, flattened with mortar and then paved. Wish.

There are many people in life who do not know what to do when they encounter this situation, and they are distressed, which not only affects the overall appearance, but also is more dangerous, what is the reason why the exterior wall tiles fall off? The main reasons are: 1. Unreasonable structural measures.

If the shrinkage joint is not installed and the installation is unreasonable. 2. The quality of the mortar at the base of the wall is low, and the tensile strength does not meet the requirements. 3.

There is a hollow drum between the insulation layer and the base wall. 4.Bond failure due to freeze-thaw cycles.

Precautionary measures: The use of infrared thermal imagers to inspect the exterior wall may predict and accurately determine the location of the hollow drum in advance.

1. If the tile falls off and the mortar does not fall off, you need to scrape the mortar clean first, then add a certain amount of cement to the glue, coat a thin layer on the prepared tile, and finally stick the tile on the original wall.

2. If the tile and mortar fall off at the same time, you need to sort out some small pits where the original wall falls off, and then apply the tile mortar and repair it.

Some old houses have been used for a long time, and the tiles on the exterior wall are easy to fall off, and the falling off of the exterior wall tiles is a very big safety hazard. So what are the treatment methods for exterior wall tiles to fall off? Let's take a look.

1. Take out the damaged wall tiles.

If the wall tiles have not completely fallen off, first use a cutting machine to cut a groove at a distance of 5-6mm around the damaged wall tiles, and then use a cutting knife to scrape off the cement on the wall tiles. Then make a hole in the glaze on the surface of the wall tile, so that it is easy to break the wall tile and take it out. If the cement sticks too firmly, you can use a hammer or other tool to remove the broken wall tiles.

2. Only the tile peels off the mortar does not fall off.

If the tile has fallen off and the mortar has not fallen off, first clean up the mortar on the tile, and then use 107 glue and an appropriate amount of cement to stir until it becomes a paste, and then use it to coat a thin layer on the back of the tile, and finally glue the tile back to the original place, and the strength should be moderate when sticking.

3. The tile and mortar fall off at the same time.

It is also common for tiles and mortar to fall off at the same time, in this case, first dig some small pits in the area where they fall off, and then use 107 glue mortar to re-paste the tiles back. In the process of pasting, you must first just press it, and then take your hand away after the mortar hardens.

4. Paste new wall tiles.

Tile falling off can also buy new tiles to paste back, first buy tile glue, adjust it evenly according to the proportion, use a tool to wipe the glue in the place where it falls off, and then use the wall tiles to align the color, and use a hammer to gently knock the surrounding of the tile, so that the air inside can be knocked out, so that the tile and the glue are better bonded, but this method is suitable for small areas of tile falling off. Secondly, you can't choose glass tile adhesive when choosing a tile adhesive, because it is more suitable for use on a single flat flat surface.
