How to test the quality of wall tile construction
1 color change. Mainly because of poor quality of tiles, too thin glazes and improper construction methods. Tiles should be carefully selected during construction and clean water should be used to soak the tiles. Paste cement paste to use pure sand cement. Always clean the remaining mortar on the brick surface during operation. If the color difference of the tiles should be replaced. 2 empty drum off. It is mainly that the bonding material is not full, the bricks are impregnated and the base layer is not treated properly. When hollow drums are produced, the wall tiles shall be removed to repair, the original bonded mortar shall be removed, and cement mortar shall be used to repair the mortar with a total volume of 3% of the qualified plastic. 3 seams are not straight. The main difference is that there are differences in the specifications of the bricks and improper construction. If the joints exceed the allowable error, remove the bricks in time and rework them.

1. Look at the use and treatment of decorative materials
The varieties, grades, specifications, shapes, geometrical dimensions, finish, colors and patterns of decorative tiles shall meet the design requirements. The stone shall be solid, uniform in color, free from cracks, deteriorating, discoloration, water lines or pollution, and the surface shall not warp. Blisters. Bricks are free of defects, falling sand, holes, falling corners, cracks and other defects, the surface is square, uniform color. Paste materials, dry hanging accessories should meet the design requirements, carbon steel parts need to do rust treatment. The ground floor should be solid, clean, and of the correct size. It is true that the error of cable inspection should be less than 2mm, and the error of flatness should be less than 1mm with a 2m ruler.
2. Look at the construction quality requirements The surface of the facing layer should be smooth and clean, with clear texture, uniform color, no warp and distortion, and no empty drums. The gaps between the facing blocks are uniform, and the filling is dense and straight. Consistent color; special parts of the brick pressure to the right, non-whole use of appropriate parts of the brick, arranged in straight lines; protruding application of the whole board sets of cut, edge anastomosis, neat, smooth, uniform thickness. The position of the hole is correct and the edge is neat; the direction of the flowing water is correct, and the drip line is straight; when the angle of the corner is 45°, the angle is correct and the lines are straight. Check the surface flatness error by 2m on the ruler less than 2mm, the vertical error of the facade is less than 2mm, the deviation of the joint height is less than 0.5mm, and the straightness of the upper end of the skirt is less than 2mm.
3. To find and solve quality defects in time
After the construction of the wall tiles, the following quality defects are likely to occur. It is necessary to carefully observe and supervise the construction personnel to solve them in time.
