The good and bad of tile shop, not only has a relationship with the quality of the tile, but also has a great relationship with the construction process, so after the completion of the tile construction, we must have a good acceptance, then how to check the ceramic tile? To look from the following aspects!
First, visual inspection
First of all, from a large area, look at the flatness of the wall. If the wall has a lot of curvature, check it further. Visual inspection also depends on whether the seam between the brick and the brick is aligned. If it is not, further inspection is whether the brick has a size difference or the worker sticks to it. Visual inspection finally depends on how Yang angle does to seams. It's too thick to look good, too thin, and it falls out of porcelain when touched.
Second, check emptying rate
Traditional craftsmanship, sand + cement paving method, it is easy to empty drums, and the larger the brick, the easier it is to appear. In the process of cementing itself, the above cement will sink, and the cement will have flexibility. You will feel that there is no empty drum just after the plaster is finished, and there will be empty space after it has dried completely. The most common empty drums are the upper half and corners of the wall tiles, and the location of the corners.
Five-point knock detection method: use a metal rod to hit the four corners and the central part of the tile, and judge whether the tile is hollowed by the sound. If the percussion sound is boring, it indicates that the paving is relatively solid and firm. On the other hand, the crisp sound of "squeaking" indicates that there is no firm affiliation and there is emptying.
Personal advice: Wall tiles are not recommended to be a little empty, slammed down and re-posted, and within a reasonable range, the people and the people should not be hurtful, but they found that a large area of ​​empty space must be smashed down and re-posted.
Third, check the yin and yang angle
If the angle of Yin Yang is less than 90 degrees, it will have a direct impact on the laying of floor tiles and the placement of hand basins and other items, so it is very important. It is very simple to check it up: A corner brick can be used; two bricks or a brick + angle can also be used.
Fourth, check the height difference and the launch slope
Generally speaking, unless the water in your home's bathroom is lower than the outside when it is being built, otherwise the sand-cemented floor is at least 3 to 4 cm higher than the outside. Grading slope test can use the level ruler. You can also use the simplest way to pour water to see if the water is leaking to the ground.
Fifth, pointing
Workers must be reminded not to dry up and let the bricks dry. At least 48 hours later, the gaps should be handled clean and uniform. In order to ensure the overall effect of tile laying, tile joints need the same width and width, it is best to use plastic cross positioning, otherwise affect the appearance.
