Six key points must be mastered in ceramic tile ac

  • Detail

Tiling is a technical activity, in which there are many stresses, which can reflect the craftsmanship of workers. If the treatment work before paving is ignored or the operation is not standardized, it is very likely to cause hollowing of tiles, large color difference and other phenomena, which will greatly affect the overall aesthetics. The following six points must be mastered during the acceptance of ceramic tiles:

see whether the original foundation treatment is in place before paving

the base course should be roughened, with a chiseling depth of 5~10 mm, and the spacing of chiseling marks is about 30 mm. According to the requirements of the construction process, if there is putty on the original wall before the wall tiles are pasted, the putty should be removed, then the smooth plastering layer should be roughened and the surface cleaned, and then roughened with plain ash, and finally the tiles should be pasted. Otherwise, the tiling cement is not firmly bonded to the base, resulting in hollowing and delamination of wall tiles

second, check whether the cement mortar on the back of the ceramic tile is full.

the mortar on the back of the ceramic tile should be full to ensure that the corners are not empty. According to the regulations, when the wall tiles are paved, the mortar should be full and firmly pasted, and the hollowing of a single corner of the wall should not exceed 5% of the paving quantity. When laying bricks, it is advisable to use 1:2 cement mortar with a thickness of 6 to 10 mm, and then use a rubber hammer to gently compact it, otherwise it is easy to appear hollowing

third, check whether the tiles have color difference

there is a significant color difference between the two adjacent wall tiles. According to relevant regulations, the variety, specification, grade, color and pattern of wall tiles shall meet the design requirements. After paving, the color of the tiles should be basically the same, without obvious color difference, clean and free of accumulation and mortar marks

look at the corner of the ceramic tile (internal and external corners)

the ceramic tile at the external corner cracked because it was not handled properly. Workers usually use light steel keel to make the framework of kitchen and bathroom package riser, paste cement pressure plate outside, and then hang metal mesh. After tiling, due to the different physical expansion coefficient between light steel keel and cement, the skeleton is easy to deform, and the corner of the wall brick is more likely to crack. It is suggested that the owner should use light bricks as the foundation for the kitchen and bathroom package riser

v. check whether the wall tiles appear “ The size of the mosaics at the innermost part of the wall is obviously small, so the size should be calculated in advance and arranged to an inconspicuous place as far as possible. According to the regulations, setting out, positioning and laying of bricks shall be carried out before laying bricks, and non whole bricks shall be laid to secondary parts or internal corners. Two rows of non integral bricks should not appear on each wall, and the width of non integral bricks should not be less than one third of the whole brick

six look at the flatness of the wall

check the flatness of the wall with instruments. 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, the smoothness of tile paving will be affected
