What are the aspects of tile paving acceptance

Take a look at the flatness of the wall According to the regulations, the flatness and verticality of the wall surface are within 2 meters, and the error is not allowed to exceed 4 mm. Otherwise, it will affect the flatness of the tile paving.

Second, see whether the original foundation treatment is in place before paving, the base should be chiseled, the depth of the chisel is 5 10 mm, and the spacing of the chisel marks is about 30 mm.

According to the requirements of the construction process, if there is putty on the original wall before pasting the wall tiles, the putty should be removed, and then the smooth plastering layer will be chiseled and the surface should be cleaned, and then the brushing should be carried out with plain ash, and finally the tiles should be pasted. Otherwise, the bonding between the brick cement and the base layer is not firm, which leads to the hollowing and delamination of the wall tiles.

Third, see whether the cement mortar on the back of the tile is full.

The mortar behind the tiles should be full to ensure that the corners are not hollow.

According to the regulations, when the wall tiles are paved, the mortar should be full and firmly pasted, and the hollow drums of a single corner of the wall shall not exceed 5% of the number of paving. When laying bricks, it is advisable to use 1:2 cement mortar, the thickness of which should be 6 to 10 mm, and then gently compacted with a rubber hammer, otherwise it is easy to appear hollow.

Fourth, look at whether the tiles have color difference.

The two adjacent wall tiles showed obvious color differences.

According to the relevant regulations, the variety, specification, grade, color and pattern of wall tiles should meet the design requirements. After paving, the color of the tile should be basically the same, no obvious color difference, clean and free of material volume and slurry marks.

Fifth, look at the corners of the tiles (yin and yang corners).

Due to the lack of treatment, the tiles at the sunny corners cracked.

Workers usually use light steel keels to make the skeleton of the riser of the kitchen and bathroom package, paste a cement pressure plate on the outside, and then hang a metal mesh. After tiling, due to the different physical expansion coefficients of light steel keel and cement, the skeleton is easy to deform, and the possibility of cracking at the corner of the wall tile is greater. It is recommended that the owner of the kitchen and bathroom package riser should be based on lightweight bricks.

Sixth, see if there are "small strips" on the wall tiles

The size of the innermost mosaic on the wall is obviously small, so the size should be calculated in advance and arranged in an inconspicuous place as much as possible.

According to the regulations, the pay-off positioning and brick arrangement should be carried out before brick laying, and the non-whole bricks should be arranged to the secondary part or the yin corner. There should not be two columns of non-whole bricks on each wall, and the width of the non-whole bricks should not be less than one-third of the whole brick.

If you don't have a lot of it, you don't need to check it at the general dealer!

Usually the number is not much, just look at the number and grade, whether the manufacturer meets the OK

If a large amount!

You can open a few boxes and take a look, and disassemble them in several places! (A few boxes are enough).

Generally, the first thing is to see if there are jumpers (whether the 4 corners of the tiles are broken).

The second is to take four pieces and spread them out to see if there is a difference in color between each piece, and whether there is a problem with the surface of the tile!

Surface problems generally manifest themselves in several places, such as leaking bottoms, walking flowers, leaking flowers, and black spots.

The bottom of the leak is to see the tiles There are some places that are different from the place, some are black, generally dot-shaped, and you can see it at a glance.

Walking is to look at the pattern of a certain part of the tile, and other places are not coordinated, obvious! Mosaic.

The black spot is to see that there are some black spots on the surface of the tile, and the third is to look at the flatness of the tile, first take a piece of brick and put it on the ground (this is to prevent the ground from being uneven, and the surface is facing up).

Then you just take two bricks and place them on top, the surfaces are facing each other, aligned, and then press the bottom of one side.

Another person is in the middle of the two bricks to see how big the crack is, there is a problem, affecting the paving effect, you can see it at a glance! ~

Tile paving acceptance, remember to pay attention to these 4 points! 1.The key points that need to be drilled in the later stage such as the window and the bathroom wall are checked for hollow drums; 2.

The gap between the tiles should not exceed 2 mm, take a toothpick, and whether the gap is perfectly integrated; 3.The wall tiles are pressed against the floor tiles, and whether the gaps are perfectly fitted; 4.Check that the floor drain is at the lowest point.

Tile acceptance: one look, two knocks, three splashes.

One look: there are many varieties of floor tiles.

According to the variety and process, it can be divided into glazed bricks, non-slip bricks, vitrified tiles, polished tiles, micronized bricks, seepage tiles and other ground tiles. There are also many quality grades: excellent, qualified, and other foreign products.

The quality of the floor tiles themselves and the quality of the inlay are often "exposed" through careful observation: the surface of the floor tiles is uneven, the corners are uneven and the surface layer of the floor tiles is bright, but there are inclusions spots in the glaze layer or glaze layer or the glaze color is different, which can generally be judged as the poor quality of the floor tiles themselves, which is a secondary product that must be replaced. In addition, the quality of floor tile decoration and inlay mainly depends on whether the flatness of the overall surface is greater than 2 mm in the range of 2 meters long, whether the height of the joints between bricks and bricks is greater than millimeters, and whether the straightness of the joints exceeds 3 mm within the length of 5 meters.

Second knock: Check whether there is a hollow drum in the floor tile inlay.

The inspection method usually uses a special small steel hammer or a small hammer and a small iron rod to gently tap the corners and middle of the floor tiles around the room to detect whether the floor tiles have hollow drum sounds. The sound is crisp and normal; If there is a hollow sound for the hollow drum, it means that the inlay is not real, the decoration quality is unqualified, and it must be removed and replaced in time. During the inspection, the hollow drum floor tiles were marked, and the floor tiles were found to be broken and violent, and they were also marked to be replaced.

Three splashes: You may wish to splash water for the test.

Brick inlay also has a drainage slope requirement for balconies, bathrooms, and kitchens. Check whether there are potholes on the floor of the bathroom, kitchen, and balcony, and whether the water is smooth, and you will know if you splash a lot of water. This "process" can be put to the end, when everything else has been checked, use the water container to fill the water and splash it on the ground, wait for a while, the water will indicate that the floor tiles are uneven, or the slope of the water is not enough.
