Wall tiles falling off how wall tiles come off what to do

Abstract] Through the analysis of the causes of wall tile sticking and falling off, appropriate maintenance plans are adopted to solve the problem of tile falling off and throwing bricks to avoid similar problems in subsequent construction.

1.Project Overview.

Tiantai Qingchengyuan project is located in the area at the junction of Jiangjun Avenue and Focheng West Road, Jiangning Development Zone, Nanjing. The total construction area is invested and built by Jiangsu Tiantai Construction and designed by Nanjing Zhongyi Architectural Design. The commencement date is August 25, 2008 and the completion date is September 26, 2012.

According to the requirements of the construction unit, the wall finish is changed to 12mm thick tiles, and the size of the tile finish is constructed according to the requirements of the construction unit, and the actual construction, the specific decoration plan is declared by the construction team, and the construction is approved by the supervision and construction unit.

At the beginning of 2011, some wall tiles in Building 1 fell off, especially in the lobby, and some tiles in the front room of the floor were falling off, while no tiles were found in Building 2. According to the requirements of the property and Party A, the falling tiles are repaired and pasted with construction glue cement mortar. By the beginning of 2012, there were more wall tiles falling off in the winter stage, and from the perspective of tile falling off, the adhesive layer and the finishing layer on the back of the tile were peeling off.

There are radial cracks on the surface of some bonded mortars, and the cracks are mainly located in the center of the plate bonded mortar.

2.Cause analysis.

The construction stage of wall tiles is July to August, when the temperature is high, and winter.

OK.. Do you dare to choose mine in the end?

Reason 1:

Improper construction process, resulting in tile falling off.

Among them, there are two reasons for improper tile paving:

1. Poor quality of mortar: the mixing ratio of mortar is inaccurate during construction, and the mixing is uneven. As a result, the sticking strength is not enough, which affects the bonding strength of the tile and the wall base, and finally causes the tile to fall off.

Solution: Replace with high-quality mortar.

2. The face brick is not compacted: the master's operation technique is wrong, and the force is uneven, so that the combination between the tile and the wall base is not enough. Or after pasting, in order to correct the deviation, the face tile is repeatedly moved, kneaded, and beaten will also cause the adhesive layer to be seriously damaged, and finally cause the tile to fall off.

Solution: The veneer brick should be firmly pasted.

Reason 2: The quality of the tiles is poor, which causes the tiles to fall off.

1. Quality problems: the water absorption rate of ceramic tiles should not exceed 18%, but the water absorption rate of many tiles has reached 20%, and the most has reached more than 25%.

Solution: Replace high-quality tiles.

2. Improper water immersion of tiles: due to the water immersion of the tiles is not in place, the paved tiles will absorb the moisture of the wall cement. As a result, the tiles and tiles are not firmly pasted and fall off.

Solution: Remove the moisture from the tiles.

There are many reasons why wall tiles can fall off, and it can be due to the long renovation of the house. It could be a problem with construction: 1

Grassroots treatment problems: the wall and ground base treatment is not clean, the watering moisture is not enough, the floating dust on the back of the tile is not removed, and there are too many water traces before paving, which will lead to the tile and the wall are not tightly bonded, and there will be loosening and falling after a period of use. 2.

Tile quality problem: The quality of the tile is also one of the reasons for loosening, and the water absorption rate of the tile directly affects the firmness of the paste. The state stipulates that the water absorption rate of porcelain tiles is E, and the shrinkage and expansion rate of porcelain tiles is about 4 10-6, when the water absorption rate of ceramic tiles or cement does not reach the standard, after the occurrence of thermal expansion and cold contraction, the shrinkage rate of ceramic tiles and cement is inconsistent and leads to separation and falling.

3.Construction process problems: during the construction process, if the cement mortar of the cushion is too thick or the cement is added too much water, the tiles will fall; In addition, if it is a large-size tile, if the seam is too small, the thermal expansion and cold contraction will squeeze each other, which is easy to cause warping and cracking.

4.Problems in daily use: the water absorption rate of the inner tile is low, if the tile is not fully fitted with the cement, it is subjected to a large impact force, such as trampling or the impact of hard objects, it is easy to cause the separation of the tile and the cement, and the bottom of the brick is hollow.

Generally, the tile falls off and can be repaired in the following ways: 1Corner hollow drums:

If it is found that there is a hollow drum on the edge of the tile after paving, the part of the partially hollow drum can be watered to avoid overall replacement. 2.Local hollowing:

If there is a small amount of partial hollowing of the tiles on the wall and floor, if it does not affect the installation of cabinets, mirror cabinets, showers and water heaters, etc., it can not be treated, but if it affects the installation and daily life, it is recommended to knock off the local tiles and re-pavement. 3.Large area hollowing:

If there are 2 3 tiles in the space, it is recommended to remove them all and re-pave.

Compared with the traditional cement yellow sand tiles, the MS glue tile effect saves the material cost of cement yellow sand, and the labor cost is also reduced a lot, and at the same time improves the construction efficiency, so I can move in early. Greenridge MS modified silane glue, all properties are excellent, sealing and waterproof, high and low temperature construction, the highest adhesion force reaches 30kg square centimeters. Moreover, Greenridge MS glue has zero formaldehyde, zero isocyanate, solvent-free, non-toxic and tasteless, and the VOC emission is far lower than the national standard, which does not damage the environmental performance of the substrate.

It has a wide range of adhesion to substrates, and most inorganic, metal, wood, concrete, ceramics, glass, stone, etc. have good adhesion properties. Good elastic deformation ability: high elastic deformation ability can ensure that the adhesive surface can adapt to various external tensile and compression deformation, absorb and compensate dynamic loads, evenly transmit the force, prevent premature fatigue of the material, and always maintain effective sealing and bonding.

If the tiles on the wall appear to fall off, it will look aesthetically pleasing. What should I do if the wall tiles fall off? PChouse will take you to find out.

1. The mortar is not loose: if the mortar is not loose, but the tile falls off, you can apply the mortar adhesive on the back and around the mortar, and then mix 107 cement into a little cement and stir it into a paste, evenly coated on the back of the thin answer, and a thin layer will grip the tile tightly behind.

2. The mortar has peeled off: if the mortar falls with the tile, you must first gently drill some hair holes on the original foundation surface, and then mix the mortar with 107 glue to re-stitch. After brushing a layer on the surface of the foundation, it will come off.

Press the bricks until the mortar hardens. It should be noted that if the tiles are only partially peeling, do not hit the mortar on the surface of the foundation with force to prevent the tiles from vibrating around the original strong tiles.

3. Junction: The old tiles are still intact, but only at other junctions at the junction, after repair, the sand at the joints can be cleaned first, and then all-purpose glue can be used, and glass glue is used to form joints after drying. In this way, the phenomenon of tile falling off is economical.

How to deal with the falling off of wall tiles？Use a knife to remove the attachments such as seam or cement around the tile and the pasted parts on the wall, and then wipe the back of the tile and the wall with a damp cloth to remove the floating ash. Use a glue gun to apply the glass glue to the back of the tile and the gap on the wall, paste the tile back to its original position, then apply the tape on both sides of the tile gap, and apply the glass glue to the gap, and tear off the tape after completion.

Nowadays, in order to better clean the wall in life, people will use wall tiles to decorate the wall. Today I will answer for you to open the lead, and friends who want to know may wish to take a look at how to avoid tile falling off!

1. What should I do if the wall tiles fall off?

If only the tile falls off, you need to scrape the mortar behind the tile, then use cement and add some 107 glue to stir until paste, apply it to the back of the tile, and paste it back. If the tile mortar is falling off, you need to dig some small pits in the place where it falls off, and then add 107 glue to the cement and stick it back again, and wait until the mortar is basically hardened, and then move your hand away.

Second, how to avoid tile falling off.

1. Choose tiles.

When selecting tiles, it is necessary to carefully check whether it is a qualified tile, in order to avoid the phenomenon of tile falling off, before use, the tile needs to be soaked, and cleaned before use, and must be dried before the wall can be used.

2. During construction.

When pasting tiles, the cement mortar used must be full, but it can not be used too much, because too much will lead to the phenomenon of uneven tiles, and it is easy to overflow the mortar, and it is easy to form a hollow drum after collecting water, especially for the balcony, the use of too much cement mortar will lead to uneven sunny corners and hollow drum phenomenon, which will lead to the tile falling off.

In the process of tiling, it should be done at one time, and it is best not to rework repeatedly.

In order to prevent the tile from falling off, the joint should be carefully done, when the joint, the cement mortar of 1:1 should be used, and the cement slurry with the color of the tile and the possibility of wiping the joint, the mortar remaining during the construction should be cleaned in time, otherwise it is easy to leave traces.

Total Jue: The above is for everyone to share what to do with the wall tiles falling off and how to avoid the tiles falling off, I believe you have a corresponding understanding after reading the above sharing, if you need to know more about it, please continue to pay attention to Qeeka Home**, will answer for you one by one.

What to do if the wall tiles fall off

1. If the back of the falling tile is relatively clean, polish the falling tile with a grinder, and then remove the debris behind it, and then directly use structural adhesive or nail-free glue to wipe it on the back of the tile and stick it directly on the wall.

2. If there is a lot of bonding or cement on the back of the falling tile, then chisel off all the unqualified base layers, then use cement mortar plastering and leveling, and then use structural adhesive to paste the falling tiles on it.

Reasons for this:

1. It may be that when the back of the tile is treated, the operation is not very in place, and the quality of the bonded material selected is not very good, or because the strength of the base layer itself is not up to standard, so the tile falls off.

2. It is also possible that the base of the wall is not very clean, and the humidity is not enough when watering, or the cement mortar is too thick, or the water is added too much when batching, or it may be that the construction party is cutting corners when working, and the quality of the cave friend itself is not good.

3. Maybe it's because the water absorption capacity of the tiles is too low, or maybe the gap between the tiles is too small, and there is a warping or cracking situation in the case of thermal expansion and contraction.
