Can the quality of the wall tiles pasted be inspected?

Yes, you can. Brick paving seems to have low technical content, but in fact, there are a lot of exquisiteness, which can better reflect the craftsmanship of the workers. If you ignore the treatment work before paving or the operation is not standardized, it is very likely to cause the phenomenon of tile hollowing, large color difference, etc., which greatly affects the overall aesthetics.

Take a look at the flatness of the wall.

Check the flatness of the wall with an instrument.

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.

You can only knock to see if there is a blank.

The quality of the tile does not lie in its thickness, but in its own texture, so how to distinguish the quality of the tile?

It is enough to choose the advantages and disadvantages of tiles with these 5 tricks: watching, dripping, listening, measuring, and trying.

First, the "view" of the tile: edge, color, light, edge straightness, color uniformity, smooth surface, smooth and no deformation for high quality.

Second, the "drop" drip water absorption rate: in addition to looking at the density of the tile, the focus is on the anti-fouling ability of the tile, the lower the water absorption rate of the tile anti-fouling ability.

3. "Measurement" hardness: ceramic tiles with good hardness and strong toughness are the top grades. Scratch the tile with a sharp object, there are scratches that the glaze is poor and easy to make people slip, and after the glaze on the surface is polished, the brick surface will not be able to be cleaned.

Fourth, "listen" to listen to the sound: knock on the tile, the clearer the sound, the higher the degree of porcelain of the tile, the better the quality. If the sound is dull, it is defective.

5. "Test" whether there are pinholes on the surface (visual observation within 1 meter): if there is, it means that the glaze is not completely integrated, and it is easy to accumulate dirt.

Have you learned how to identify tiles? Remember to be practical, remember to pay attention to Brother Pin, and push selected dry goods for you every day.

1. Empty drum rate According to the regulations, 5% of the empty drum rate is allowed. If it's too much, let them rework. You should understand the empty drum rate, right?

2. Is the tile flat flat? Use a two-meter-long ruler to stick it on the wall tiles or floor tiles to see if there are any gaps, if there are, it means that the bricks are not flattened and reworked.

3. Utilization. When cutting bricks, is it reasonable? On a wall, only one brick is allowed to be cut, usually used in the corner.

For example, a wall, starting from the top, is a whole brick, and until the ground, a brick and a half will appear. If one wall is cut in two, it is a waste. Do you understand that?,I don't think I'm expressing myself well enough.。。。

4. Bonding Press the tile by hand to see if there is any shaking, if there is, then this turn will fall off sooner or later, when the cement is on, it will not absorb enough water and rework. It must be very strong when pressed, and it must not be moved.

5. The horizontal line is the edge of the brick, which means that it is very neat in the past, and this can generally be achieved.

6. Clean Whether it helps you clean up the tiles, whether there is cement or paint, these are all things that must be cleaned up.

That's basically it, check it well, don't be soft-hearted.

The process of ceramic tiles, on two points, first of all, do not empty drums, second, the layout should be reasonable, that is, after the completion of your eyes to look pleasing to the eye, about the first point of inspection, you only need the iron guy that is not big or small to knock, knock when do not break the tiles, (in case the empty drum tiles can still be used), knock when listening to the sound, the sound of the empty drum and the solid sound is not a fool can be separated, especially pay attention to the four corners of the tile, the position of the level of personal dry is basically empty, empty tiles are easy to break. The second point depends on your hobbies.

Take a brick to measure whether its side length meets the requirements, and then take several bricks stacked together, compare whether its size is consistent, the size error will not only increase the difficulty of construction, but also affect the effect after decoration. The deviation of small bricks is promised to be 1 mm, and large bricks are promised to be 2 mm. The size of the deformation.

Take two bricks side by side, depending on whether the side seam is small and straight, the edge straightness is good; Then the two bricks are buckled together to see if the gap is small and straight, and the flatness is good. **Whether there is concave or convex on the side of the tile, the front side is flat and slightly convex, if the warping situation is severe, it will affect the firmness of the tile in the future. The size of the dimensional deviation and the size of the deformation determine the size of the mortar joint, the straightness and the flatness of the decorative surface of the tile paving.

Note: The size between different varieties of mixed paving, accessory bricks, waist line bricks and main bricks should be matched. The size of the color difference.

Because the number of wall tiles purchased at one time is larger, if there is a significant color difference between multiple packages, the decoration effect will be very affected. Surface. Observe whether the brick surface is delicate and average, and observe whether the product has significant quality defects such as lack of glaze, freckles, cracks, glaze bubbles, ripples, etc., and the above defects must not be selected.

Then you can use a few drops of colored liquid drops on the local surface to coat evenly, wipe dry with a damp cloth after a few seconds, and observe whether there are residual color spots on the surface. If it can't be scrubbed, it means that the brick has a large water absorption rate and poor stain resistance. (2) Determination of intrinsic quality knock. Use a thin stick to lightly buckle (or flick with your fingers) the suspended tile, the sound is crisp, indicating that the tile has no cracks, good sintering degree and high strength; If the sound is muffled, it means that there may be heavy skin or cracks in the tile

Heavy skin is when the brick is formed, the air in the material is not discharged, resulting in a bad combination between the material and the material, internal cracks, can not be seen from the surface, only listen to the sound to identify. Hand plucked. The tile components are heavier and more solid.

This is mainly because of the selection and ratio of raw materials, the better the tile, the greater the mechanical pressure during processing, so the weight is also heavier. Drip. Drop a few drops of clean water on the back of the tile, observe the absorption speed, the faster the absorption, the greater the water absorption.

Generally speaking, products with low water absorption, good sintering degree, high strength, good antifreeze function, and excellent product quality. Scrape. Scratch the glaze of the tile with a sharp object to see if there are scratches, if there are scratches, it means that the glaze is poor and easy to make people slip, and the surface of the glaze is polished, and the brick surface will not be able to be cleaned.

Summary. Dear, check whether the floor tiles are pasted well: first:

Listen to the sound, the tile hollow drum affects the firmness, generally speaking, it doesn't matter on the ground, because there is no risk of falling off, but the wall must be noted, once it falls off may be dangerous, you can prepare a metal stick to knock it, a little weight of the kind, of course, the fingers buckle up to knock also. If it is sticky and strong, it is a better crisp sound to knock on, if there is a hollow drum, it will be a bit of a dull sound of knocking, the appropriate hollow drum is OK, but a large number of hollow drums are not suitable, and the possibility of falling off will become larger, although there is no problem in a short time, but the house is to live for decades.

Pro, check whether the floor tiles are pasted well: first: listen to the sound, the tile hollow drum affects the firmness, generally speaking, it doesn't matter on the ground, because there is no risk of falling off, but the wall must be noted, once it falls off may be dangerous, you can prepare a metal rod to knock, a little weight of the kind, of course, the fingers can be buckled up to knock.

If it is pasted more sturdy round, knocking on it is a better crisp sound, if there is a hollow drum, there will be a bit of a dull sound of knocking, the appropriate hollow drum is OK, but a large number of hollow drums are not suitable, falling off the Tongmu letter may be resistant to become larger, although there is no problem in a short period of time, but the house is to live for decades.

The first front two: measure vertical, for some corner positions, the better the verticality, the more neat the nature, this simple look is not accurate skin, you need to prepare a ruler to detect, as long as the difference is not too big, no more than three degrees there is no problem, after all, the neat 90 degrees is not easy to do, small errors can not be avoided. Burn the missing key.

Third: Measuring leveling, in fact, is to see if the ground is flat, the smoother the ground is naturally the better, of course, this can not just look, or to use the horizontal cavity Zheng Zhi ruler to measure, relatively simple, to see if the bubbles on the ruler are in the first position of the room, flat ground Wu Min's words, the bubbles will be in the positive position, if the deviation is far, it means that this level is not good.

Summary. 1.Check the flatness of the tile paving, you can use an aluminum alloy square pipe about 2m long (or other items that can be used as a ruler) to put on the pasted tile, if the tile surface can be tight and seamless with the square pipe, it is a very qualified tile construction.

2.Check the joints when the tiles are paved, and through visual inspection of the tiles that have been paved, the joints are perpendicular to each other, and the gaps are uniform, the filling between the joints is not overflowing or concave, and the joints between the dense materials should meet the requirements.

3.Check whether there is a hollow drum phenomenon in the tile paving, use a wooden stick or hammer a wooden handle, hold the wooden stick with two fingers, stand and walk around while tapping the middle and four sides of each tile one by one, pay attention to it, be sure to check after 3 days of tiling. If the percussion sound is empty, it is the sound of empty drums, and the sound of the sound is more solid, how to check whether the floor tiles are pasted.

Dear, hello, please wait a moment, we have seen your question in Bishan, and we are sorting out the information for you quickly, and we will send your answer to the little master immediately. Thank you for your support, recognize my service, and remember to give a thumbs up<>

<>1.Check the flatness of the tile paving, you can use an aluminum alloy square pipe about 2m long (or other items that can be used as a ruler) to put on the pasted tile, if the tile surface can be tight and seamless with the square pipe, it is a very qualified tile construction. 2.

Check the joints when the tiles are paved wide and pasted, and the tiles are visually inspected and pasted, the joints are perpendicular to each other, and the gaps are uniform, the filler between the joints is not overflowing or concave, and the joints between the dense materials should meet the requirements. 3.Check whether there is a hollow drum phenomenon in the tile paving, use a wooden stick or hammer a wooden handle, hold the wooden stick with two fingers, stand and walk around while tapping the middle and four sides of each tile one by one, pay attention to it, be sure to check carefully after 3 days of tiling.

If the percussion sound is empty, it is an empty drum sound, and the sound that sounds dangdang is more realistic

1. First of all, you check it again, check the specific method: first.

First, you bend your fingers, try to knock on each tile, and listen to the sound to see if there is a hollow drum. Clause.

Second, check whether the tile joints are pasted unevenly.

2. If there is a hollow drum or uneven tile paste, you can take the following methods

1. If the mortar is not loosened, only the tile falls off, the back of the tile and the mortar adhered around the mortar can be scraped clean, mixed with a little cement in the 107 glue into a paste, evenly coated with a thin layer on the back of the tile, and then the tile can be glued firmly.

2. If the mortar falls together with the tiles, first gently chisel some pits on the original foundation surface, and then re-inlay them with mortar mixed with 107 glue, or use cement, E 44 epoxy resin, acetone, ethylenediamine (available in chemical stores) according to 5:3:2:

After mixing well in the ratio of 1, brush a layer on the foundation surface with a brush, and then press the peeling tile until the mortar hardens.

It should be noted that if the tiles are only partially falling off, do not hit the mortar on the foundation surface to prevent the original solid tiles around from being loosened.

Hope it helps.
