01. Wall tiles, stone varieties, specifications, colors and patterns should meet the requirements of the design and occupants, and the surface must not have scratches, missing edges, and other quality defects.
02. Before using a wall tile, carefully inspect the wall tile dimensions (length, width, diagonal, flatness), color difference, type, and color number of each piece to prevent mixing.
03. grassroots clean-up, such as the wall is the coating base, must be removed after the water to clean up the paint, and the cutting depth is not less than 50mm, the spacing is not more than 5mm, and brush the cement slurry 1 will.
04. Check the flatness and verticality of the grass-roots level. If the error exceeds 20mm (check with a 2-meter ruler), use a 1:3 grout to make a leveling before proceeding to the next process.
05. Before the construction, brush a wall of pure cement slurry on the wall. Before using the wall tiles, the bricks shall be fully soaked in water and moistened, and dried for use.
06. Determine the typesetting of the wall tiles, and arrange them horizontally and vertically on the same wall. It is not appropriate to have more than one row of non-complete bricks, and the non-complete bricks should be arranged at the secondary sites or the female corners.
07. Cement uses Dachang No. 425 cement, the volume ratio of cement mortar is generally 1:2.5-1:3, and the bonding thickness is 8-15mm.
08. Wooden wall partition wall tile, should first hang on the wooden base stencil, brush a net slurry, plastering the base after plastering the wall.
09. Before the wall tiles are glued, horizontal and vertical control lines must be identified, and the footing should be well-kept and sticked so that the surface is flat. The paste should be carried out from the bottom up. The whole or independent part must be completed on the same day, or the joints must be left on the corner.
10. When wall tiles are pasted, the flatness is checked with a 1M ruler, the error is ≤ 1mm, the 2M ruler check, the flatness ≤ 2mm, the gap width between adjacent ≤ 2mm, the flatness ≤ 3mm, the difference between the heights of the joints is ≤ 1mm.
11. The wall tiles must be firmly attached without any defects such as skew, missing corners, and cracks. Hollowing control is 3%, and the empty area of ​​a single piece does not exceed 10%.
12.Before inlaying the waistband bricks, check whether the dimensions are in line with the size of the wall tiles. Generally, the waistband of the waistband bricks should not be lower than 800mm from the ground. Generally, the bricks above the three bricks are belt belts.
13. The yin and yang corners of the wall tiles must be inspected with angles of 90°. The corners of the bricks must be angled at 45°. The angle of contact must be tight, and the gaps must pass through. When the wall tiles cut the position of the switch socket, the position must be accurate to ensure that the switch panel is installed. The gap is tight.
14. During the paste of the wall tiles, the mortar between the brick seams must be full and emptying is strictly prohibited. Damaged corner defect tiles must be replaced. After the uppermost layer of the wall tile is plastered, apply cement mortar to fill the upper void to prevent cracking of the wall tile when the ceiling of the buckle plate is drilled.
15. The bottom layer of the wall tiles should be left until the floor tiles are completed and then subsidized. When you purchase the wall tiles for the second time, you must bring bricks and choose the bricks of the same color.
16. The knots between the wall tiles and the washstands, bathtubs, etc., shall be attached after the washstands and bathtubs are installed.
17. When wall tiles are affixed, the outlet hole of the switch panel or the water pipe is in the middle of the wall tile, and the wall tile is not allowed to be disconnected. The cutting machine is used for boring and the boring hole should be tight. When wall tiles are affixed, the intersection with the door opening should be considered to be flat, and the door line should completely cover the gap.
18. Within 1 hour after the wall tile is finished, it must be used for white cement and talc joints to clean and clean. After the inspection and acceptance, the joints should be sewn once, and the wet cement and talcum powder should be used to clean the joints.
