Teach you to test the quality of wall tiles construction

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, and the stone shall be solid, uniform in color, free of cracks, deterioration, discoloration, and the water-free or formaldehyde treatment shall be carried out simultaneously throughout the country." Href="http://conrida.letfind.com.cn/" target="_blank">Contamination, no warping on the surface, no blisters, no defects on the tile, falling sand, holes, falling corners, cracks, etc. Smooth, consistent color.Adhesion of materials, dry hanging accessories should meet the design requirements, carbon steel parts need to do rust treatment.The base layer needs to be solid, clean, the size is correct, the surface layer affixed to a solid installation. Indeed; pull line inspection error should be less than 2 In millimeters, use a 2 meter ruler to check the flatness error to less than 1 mm.

2. Look at construction quality

The surface of the facing layer is required to be smooth and clean, with clear texture, uniform color, no warp, no emptying; the gap between the facing blocks is uniform, and the filling is dense, straight, and uniform in color; Block pressure is correct, non-whole bricks are suitable for use, and are arranged in a straight line; protruding objects are applied with whole-plate cleaving, the edges are anastomized, neat and smooth, and the protruding thickness is the same. 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 Wall tiles are prone to the following quality defects after construction. Carefully observe and supervise the construction personnel to solve them in time.
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 errors, the bricks must be taken off in a timely manner and the work must be reworked.
