How to accept the pasted tiles?

When the merchant sends the tile to your door to ask you to accept, how can you rest assured after acceptance, the following will teach you some simple identification methods:

One. Product appearance quality identification, the tile is placed in a well-lit place for appearance quality identification

1) The size deviation is corrected, and the two identical bricks randomly selected are overlapped together to see if the size is consistent; Dimensional errors greater than millimeters cannot be used for construction.

2) Deformation calibration, overlap the two bricks to see if there is a gap in the middle, and the flatness is greater than the millimeter of the product, the effect after decoration is poor, and it cannot be used for engineering.

3) Chromatic aberration size: randomly take a few bricks from multiple packages and place them flat on the plane, and visually check whether their hue is consistent two meters away.

4) Surface quality: observe whether the brick surface is delicate and uniform, whether there are visible defects such as spots and holes, and then you can use a few drops of colored liquid to paint evenly on the local surface, and wipe dry with a damp cloth after a few seconds to observe whether there are residual color spots on the surface.

Two. Judgment of intrinsic quality:

1) Knock: Gently tap (or flick with your fingers) the suspended tile with a thin stick, and the sound is crisp indicating that the density is high and there is no mezzanine.

2) Water absorption: When buying wall and floor tiles, we should pay attention to their water absorption, and the water absorption rate of high-quality wall and floor tiles is very low. The wall and floor tiles with high water absorption rate will be cracked on the surface of the tiles and the whole wall and floor tiles will peel off after cold shrinkage and thermal expansion.

If the water absorption rate is not indicated on the wall and floor tiles, you can put tea or water droplets on the back of the wall and floor tiles, and check the diffusion degree of the water droplets after a few minutes.

If the above is qualified, it can be accepted.

There are three standards for tile paving: the first is tile to joint paving, which requires the standard alignment of cross joints, otherwise a brick paste is crooked and several bricks around it are also crooked, and the whole wall looks very unsightly, the second is flatness, check whether the four corners of the tile are flat, and the third is the hollow drum rate, a single brick is not more than 5%, and the hollow drum is not allowed in the middle, and the whole wall is not more than 15%.

1. Surface: Check whether there are missing edges, corners, and porcelain, in addition to the quality factors of the product itself, it is also necessary to guess the protection of the finished product after construction.

2. Chamfering: The joint of the two tiles at the sunny corner should be kept 45° chamfering, otherwise the overall appearance will be affected.

3. Joints: The gaps between bricks and bricks should be uniform and flush, too large or too small are not good-looking, usually many masters will use toothpicks to control the spacing when paving.

4. Opening: There are many pipelines in the kitchen and bathroom, and the problem of opening holes in the tiles is often encountered, so you can focus on the opening when accepting, whether the size is correct, and whether the corners are smooth.

5. Color: In the place of applique bricks, it is necessary to focus on whether the pattern connection is natural and smooth, and whether there is a problem of misplaced and uneven pasting.

6. Check the hollow drum bricks: knock on the surface of the tile by hand or drum hammer, the sound of the qualified paved tiles is dull, on the contrary, it is the hollow drum bricks, which are easy to fall off in the future, and they should be knocked off from the shop.

7. Soaking time: the tile should be soaked in water before paving, the soaking time depends on its density, and you can ask the master how long it has been soaked during acceptance, generally it is better to not blister in the basin, about 2 hours is better.

8. Loss of Zen situation: The loss of ceramic tiles is related to its own quality, process and room type, and the normal loss rate is 5-10%, and the larger the size, the more macro dust is lost.

9. Flatness: Put it in a horizontal position with a ruler of 2m, and then use a feeler gauge to plug it in the warped place, and read it from the feeler gauge, generally speaking, it does not exceed the range of 2 mm of the acceptance standard, which is normal.

After the tile is paved, look at the flatness of the wall according to the provisions of the wall appearance flatness and appearance degree within two meters, the error is not allowed to cross 4 mm, otherwise it will affect the flatness of the tile paving, tiling Yang Hui and the lower restaurant, when it is unstable, it will cause the wall tile risk, showing hollowing, delamination and other phenomena.

1. Look at the flatness of the wall according to the regulations, the flatness of the appearance of the wall, the straightness of the lead is within 2 meters, and the error is not allowed to cross 4 mm, otherwise it will affect the flatness of the tile paving, otherwise the bonding between the brick ash and the lower layer is unstable, which causes the wall tiles to appear hollow and delamination.

2. Look at whether the mortar on the reverse side of the tile is full According to the regulations, when the wall bricks are paved, the mortar should be full, adhered and stable, and the hollow drum of a single corner of the wall does not suffer from five percent of the number of paving at the time of paving, and the thickness should be 6 to 10 mm, and then gently compacted with a rubber hammer, otherwise it is easy to show the phenomenon of hollowing.

3. According to the relevant regulations, the variety, specification, grade, color and pattern of the wall tiles should meet the preset requirements, and the color of the tiles after paving should be basically consistent, no color difference, clean and no material volume and slurry marks.

4. Look at the tile corner (yin and yang corner) where the workers use the light steel keel to make the fan bone of the kitchen and bathroom riser, paste the ash pressure plate outside, and then hang the metal mesh after the brick, because of the difference between the physical expansion coefficient of the light steel keel and the ash, the fan bone is easy to change, and the possibility of cracking at the corner of the wall tile is greater.

5. See if the wall tiles are presented as "small strips" According to the regulations, the laying of bricks should be carried out before the positioning and arrangement of bricks, and the non-whole bricks should be arranged to the non-main parts or the dark corners, and the width of the non-whole bricks should not be less than one-third of the whole bricks.

In home decoration, after the wall is tiled, it is necessary to check whether the quality of the project is passed. So, what are the basic criteria?

1. The surface is clean, there shall be no scratches, the color is uniform, the pattern is clear, the seams are uniform, and there are no cracks, missing edges, falling corners and other phenomena in the plate;

2. When the wall tiles are pasted, the flatness is checked with a 2m ruler, the flatness is 2, the width of the gap between the adjacent is 2, the straightness is 3, and the height difference of the joint is 1.

3. The wall tiles must be firm and not skewed when pasting. The hollow drum is controlled at 5% of the total, and the area of a single hollow drum does not exceed 10%.

4. The yin and yang angles of the wall bricks must be checked to 90 degrees with an angle ruler, and the yang angles of the bricks must be 45 degrees, and the corners are tight and the gaps are through.

5. When the wall tile cuts the position of the switch socket, the position must be accurate to ensure that the gap between the switch panel is tight.

6. The hole at the outlet of the pipe of the wall tile should be tightened.

7. When the wall tiles are inlaid, the intersection with the door opening should be smooth, and the gap should be straight and even.

See if the gap is a line, the floor tiles should not hang the sole when rubbed with shoes, and the bricks with a hammer should not exceed 3%.

Decoration tiling acceptance process:

First, visually inspect whether the brick joints are obviously different in size, and whether the cross joints are misaligned up and down, left and right;

Second, take a 2-meter ruler, horizontally, vertically, and the standard acceptance does not exceed 2mm;

3. The verticality of the wall is less than 2mm;

Fourth, take a small hammer and tap it on the perimeter of the brick to see if there is a hollow drum, no more than 3% qualified.

After all the above descriptions are qualified, the acceptance is qualified.
