The tiles in the home have been pasted, what method can be used to check whether the tiles are hollo

You can tap the floor with your fingers, and if the sound is crisp, then there will be a hollow drum, and the consequences are very serious.

We can directly knock it with our hands, and then in the process of knocking, we can see whether there is such a hollow tile.

Five-point percussion detection method: use a metal rod to hit the four corners and center of the pasted tile, and judge whether the tile is hollow by the sound of percussion. If the sound of percussion is dull, it means that the paving is more solid and firmer.

On the contrary, if there is a crisp sound of "dong dong", it means that the wall and floor tiles are not firmly paved and there is a hollow drum.

The quality acceptance regulations of ceramic tiles in different regions are slightly different, but generally speaking, regarding the hollow drum rate of ceramic tiles, the hollow drum rate of ground tiles should be controlled within 3%, and there can be no hollow drums on the main channel; The hollow drum of the wall tile needs to be controlled within 5%, that is, the hollow area of a tile cannot exceed 5% of the tile area. If the hollow drum area exceeds the specified area, it needs to be reworked and repaired.

Hollow drum workaround.

The common way to repair the hollow drum is to shovel the sand ash, refill it with quick ash, and re-batch the putty after drying.

However, some hollow drums, due to the location and other reasons, it is difficult to chisel out, such as the hollow drum between the concrete protective layer and the base layer is more difficult, some more expensive stones, the hollow drum between the ceramic tile and the base layer, and the stone damage economic loss is greater after chiseling. This type of hollowing can be solved by the method of perfusion repair.

The AB resin grouting repair of some engineering crack treatment centers can inject high-strength adhesive into the hollow drum, and the empty position can be filled with full adhesion and compression resistance. This kind of grouting repair hollow drum method is fast, does not damage the base, especially in the underground garage, plant and other sites, the construction process does not affect the use of the owner, is a more convenient way.

The plastering of the base layer of the wall is not treated as required.

The plastering layer is used with the naked eye**, and the hollow drum part is generally slightly higher than the overall plane around, and is often accompanied by cracks, and you can find that the inside is empty when you press it down with your fingers.

When the bricks are gently struck one by one with a small hammer, you can hear a hollow sound that is different from the sound of other parts, which is called "hollow drum" here.

First of all, 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 to hit the back of the tile, using multi-point distribution as well. Finally, level with a rubber hammer. It is recommended to use 2kg of ExxCare's caulk for the joint.

Construction method: 1Base 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.

It is recommended that you can also choose Oriental Yuhong's products.

Tile adhesive (strong).

Tile adhesive is made of cement + graded sand + polymer admixture mixed by modern technology, mainly used to paste ceramic tiles and stones of various specifications and materials, with various advantages such as labor-saving, material-saving, low cost per unit area, safety and reliability.

It can be used both indoors and outdoors, with a focus on the outdoors.

Home improvement, residential buildings, business hotels, office buildings, commercial centers, hospitals, gymnasiums.

Product construction technology].

1. Grassroots treatment.

The base layer should be solid, clean, not shaking, no oil stains, no wax stains, no concrete curing agent and other loose materials; In the base with high water absorption rate or in a high temperature and dry environment, the base must be wetted before construction. The flatness of the base layer should be less than per meter, and if it does not meet the requirements, it is leveled or a scraper with a large tooth depth is selected.

2. Preparation of glue.

First add the water to the mixing barrel, then slowly add the powder while stirring, stir with an electric mixer until it is uniform and free of lumps, place it for 3 minutes, and fully stir again before it can be used, the best time for use is 1 hour, and the water consumption is shown in the certificate.

3. Construction technology: Toothed scraper construction should be used for tiling tiles.

The adhesive is applied to the base layer with a toothed scraper so that it is evenly distributed and toothed in strips. Apply about 1 square meter each time, and then knead the tiles on it during the drying time; The depth of the scraper teeth should consider the flatness of the working surface and the convex and concave degree of the back of the tile.

Tile hollow drum, the easiest to judge is from the sound part, generally two or three days after the tile is paved, gently tap on the brick surface, it sounds very heavy, basically if the sound feels very empty, the echo is very heavy, it is a hollow drum.

You can take a wooden hammer and tap it, if you hear the sound echoing, the muffled tom is a hollow brick, if it is very crisp, it is not.

1. Choose to find a wooden stick, or a small hammer, and wrap your head with a thick cloth.

2 Then start to knock on the paved tiles, 3 when knocking there will be two sounds, one is a very solid sound, one will appear, the sound of the empty inside, 4 The sound of the empty is knocking on the air, looking for a water-based pen to draw out the mark, 5 and then find a decoration worker, to smash the tile at the hollow drum, from the new block.

Generally, the position of the hollow drum is more in the upper half and four corners of the wall tiles, and the position of the yin corner paving.

The five-point percussion detection method can be used:

Hit the corners and center of the tile with a metal rod to determine whether the tile is hollow by the sound it makes.

If the percussion sound is dull, it means that the paving is more solid and firmer. On the contrary, it makes a crisp sound of "dong dong".

It indicates that there is no firm paving, and there is a hollow drum.

We suggest: it is not recommended that the wall tiles have a little hollow drum to be removed and repasted, within a reasonable range, do not waste money and money, but if you find a large area of hollow drums, you must pick it off and repaste.

Long strips of metal, such as small hammers, stainless steel chopsticks, etc.

Tap it gently, like picking a watermelon.

1. What harm will tile hollowing cause to home decoration?

Second, how to determine whether the tile is hollow?

3. What should I do if the tiles cause hollowing?

Once the tile appears hollow, then it is necessary to repair the tile hollow area, if the hollow drum area is not very large, you can use special glue mixed with a small amount of cement to dissolve into a mixed slurry, the back of the tile is compacted and compacted; If the hollow drum area is too large, then it is necessary to remove all the hollow drum area and repaste, although it will cause a certain loss, but in order to avoid a greater increase in the later loss, it is better to peel off and repaste in the early stage.

In this case, the only way to do this is to knock off the hollow tile and reattach it to a tile, because if you don't knock off the hollow tile, the tile will squeeze the normal tiles around it, and eventually lead to a large number of tiles hollowing or cracking.

Find a professional technician to repair it, fill in the floor and re-tile. It may be better to decorate with a different type of floor tile.

I think it's better to knock out the floor tiles and rebuild them in this case.

Brick hollowing is a serious quality problem, which will cause the floor tiles to crack and fall off, and they are easy to break when loaded. Therefore, the floor tiles can not have hollowing, and special attention should be paid to the acceptance. To check whether the floor tiles are hollow, the method is actually very simple.

The professional detection method is to gently tap the ground with a detection hammer or gently sweep along the surface of the ground, if there is not a crisp "dangdang" sound, but a hollow "Dongdong" sound, it can be judged to be a hollow drum.

If you don't have a professional detection tool, you can also find a metal object, knock on the ground one by one, and find out the hollow floor tiles according to the different sounds.

There are many reasons for the hollowing of floor tiles, generally speaking, there are the following aspects:

1。caused by the construction process.

Wet-laid floor tiles are prone to hollowing. When wet paving, due to the high moisture in the cement mortar, in the natural drying process, the moisture penetrates into the base layer, and large and small cavities are formed after drying, and the floor tiles can not be fully bonded with the base layer, and there will be hollowing.

2。Technical problems in construction.

Floor tile laying is the most common construction method in decoration construction, but the technical requirements are still very high. Unskilled workers in the construction process, due to human problems such as improper operation. Hollow drums can also form. It is mainly manifested in the following aspects:

The base layer is not cleaned. The ground has not been thoroughly cleaned, there are still floating soil or sand particles left on it, and the cement mortar is actually glued together with the floating soil sand particles after being paved, and it is not integrated with the ground, and after solidification, it often causes the surface floor tile to be separated from the base floor, forming "two layers of skin", and it is easy to appear hollow over time.

The ground is not watered enough to moisten. Water is indispensable in the process of cement solidification, so if the ground is not wet, it is difficult to solidify firmly with the cement mortar.

The underlayment mortar is laid too thick or added too much water, or it is not fully compacted.

The floating ash on the back of the floor tile is not brushed clean, or it is not moistened enough with water, which affects the paste.

After paving, the floor tiles and the base layer are not completely dry, and the floor tiles are loosened and fall off due to external forces, such as walking and knocking on them.

3。Cut corners.

In order to save time and materials, some decoration teams often only plaster sand and plaster the four corners of the floor tiles, and then pave the floor tiles. As soon as it is laid, because the four corners are fixed, the floor tiles look very firm, but there is no sand and ash in the middle under the floor tiles, and it will cause hollowing due to different expansion coefficients over time.

4。Environmental and seasonal reasons.

Due to the change of seasons, if the temperature drops suddenly, causing the ground to freeze, the moisture in the mortar will not be completely dried when the cement mortar is not completely dry. When the temperature rises, there will be a hollow drum between the floor tiles and the base layer due to thermal expansion and cold contraction. There are many reasons for the formation of hollow drums, such as external force, floor tile deformation, inferior cement and other material quality problems will make the floor tiles hollow.

1.Check the floor tiles, tools on the spot to take a wooden stick, with two fingers to hold the stick, standing, while walking around while tapping the middle and four sides of each floor tile piece by piece, note, be sure to paste the brick 3 days after checking, the floor heating after the knocking sound is the same, empty. 2.

Check the wall tiles, tools on the spot from small wooden sticks, oilers with a knife (with a blade with a wooden handle), etc., tap each wall tile in the middle and four sides, note, be sure to paste the brick 3 days after checking, the load-bearing wall and the insulation wall, non-load-bearing wall, the sound of the riser is not the same. 3.Check whether the wall and floor tiles are hollow is mainly to check and confirm whether the drum is hollow by listening to the changes in its percussion sound, and it sounds like the sound is more real and no problem, on the contrary, the sound of the empty drum after percussion indicates that it is a hollow drum, note:

Walls with insulation layers, and wall and floor tiles with floor heating should be identified as appropriate. Be careful, don't hit with brute force, or you'll crack, it's best to do it in front of the foreman, who knows better than you know when he hears those knocks! 4.

Rework the foreman as appropriate!

How to check whether the wall and floor tiles are hollow:

1. Check the floor tiles.

Tools take a wooden stick from the local material, hold the wooden stick with two fingers, stand, while walking around and tap the middle and four sides of each floor tile one by one, pay attention, be sure to check after 3 days of tiling, the knocking sound after the floor heating paving the floor tiles is the same, empty.

2. Check the wall tiles.

Tools are made of small wooden sticks, oilers use knives (take the blade with a wooden handle), etc., tap on the middle and four sides of each wall brick, pay attention, be sure to check after 3 days of tiling, the load-bearing wall and the insulation wall, non-load-bearing wall, the sound of the riser is not the same.

3. Check whether the wall and floor tiles are hollow.

The main thing is to check whether it is a hollow drum by listening to the change of its percussion sound, and the sound that sounds proper indicates that it is more practical, on the contrary, the sound of being empty after percussion indicates that it is a hollow drum.

Be careful, don't hit with brute force, or it will crack.

Ceramic tiles occupy a very important position in home decoration. Not only the floor wall of the bathroom, kitchen and balcony is indispensable, but also the hall, dining room and living room often need to be decorated with ceramic tiles, therefore, the quality of the tiles themselves and the quality of the inlay will directly affect the living quality, overall appearance and use function of the house. The paving method of ceramic tiles is actually very simple, but the details of paving are often easy to be ignored, resulting in the problem of tile hollowing, so the following points should be paid attention to when paving:

First, the coating of cement should be uniform and full.

The method of tile laying is actually very simple! But the simpler it is, the more detailed it is, the more problems will occur, just from a plastering cement mortar, whether it is empty or not depends entirely on it. Cement mortar should be evenly smeared and full, and the most important part is often the four sides of the brick, which often makes many people too negligent.

Second: the cement at the upper end of the brick is evenly coated to avoid hollowing. After the wall tiles are pasted on the wall, because it takes some time for the cement to solidify, there will be sinking and solidification, so the key link is at the upper closing place of the wall tiles, which has just fallen to the sinking and solidifying.

Three: the four sides of the tile groove should be filled with cement saturation.

Four: wipe the cement mortar of the brick joint clean to avoid adding the joint agent to black.

Regarding the problem of caulk, it is best to let the mason immediately wipe the cement mortar of the brick joints after laying a piece, which will help the caulk not to turn black immediately in the later stage.

Five: measure the horizontal and vertical degree of tiles.

Six: Especially when paving wall tiles, if a layer is not paved, it is best to measure it once to keep it neat and beautiful.
