Xi'an Decoration Classroom Wall Tile Paste Engineering Construction Process, Process and Acceptance Criteria
1. The standard procedures for wall tile paving are: grassroots floor cleaning → ground floor ash → brick selection → infiltration → row bricks → bouncing line → paste standard points → paste wall tiles → hooking → scuffing → cleaning.
2, wall tiles, stone varieties, specifications, colors and patterns should meet the design, households requirements.
3, before the use of wall tiles, we must carefully check the size of the wall tiles (length, width, diagonal, flatness), color, type, and the color number of each piece to prevent mixing and other mixed grades.
4, the grassroots clean-up, such as the wall is the coating base, must be removed after the water spray paint clean, and the cutting depth of not less than 5mm, spacing is not greater than 5cm, and brush the cement slurry 1 times. In addition, all types of dirt on the wall should be cleaned and watered and moistened one day in advance. For example, when the grass-roots level is a new wall, when the cement mortar is 70% dry, bricks, bullets, and tiles must be placed.
5. Check the flatness and verticality of the grass-roots level. If the error exceeds 2cm (check with a 2-meter ruler), use a 1:3 cement mortar to make a leveling before proceeding to the next process.
6. Before the construction, brush the net slurry on the wall again. Before the wall tiles are used, the bricks shall be fully soaked and moistened so as not to bubble. Take out and dry them for use.
7. Determine the typesetting of the wall tiles, and arrange them in a vertical and horizontal arrangement on the same wall. The non-complete bricks should be arranged at the secondary site or the female corner. Tiles with a width and height of 10 cm or less cannot be placed on the wall. The wall tiles should be divided, that is, on the two sides of the wall, the bricks should not be maintained at the same time to maintain the appearance. High-grade matching bricks require five-edge seams (that is, on the basis of four-edge seams, wall tiles and floor tiles are also required to be seamed).
8, the use of cement cement manufacturers, cement mortar volume ratio is generally 1:2.5-1:3, bonding thickness 8-15mm.
9, wood for the partition wall tile, should first hang on the wooden base stencil, brush the net slurry again, plastering the base layer and then paste the wall.
10, before the wall tiles paste must be accurate horizontal and vertical control lines, good bottom (pay attention to the elevation and location of the floor drain, the bottom must be placed level, secure), paste the line, so that the surface is flat, paste should be bottom-up To proceed, complete or separate parts must be completed on the same day, or leave the connector at the corner.
11, before the belt tiles in the paste, to check whether the dimensions and the size of the wall tiles to coordinate with each other.
12. During the process of wall tiles inlaying, the mortar between the brick seams must be full and no emptying is allowed. 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.
13, the bottom layer of wall tiles, should be left until the end of subsidies for tiles. When you purchase the wall tiles for the second time, you must bring bricks and choose the bricks of the same color.
14, the wall tiles and washbasin, bath and other contacts, according to need, can be installed in the washstand, bathtub can be subsidized.
15. When the wall tiles are affixed, the switch panel is used to cut the holes of the cutting machine, and the boring holes shall be tight. Meet the outlet pipe of the water pipe in the middle of the wall tile. The wall tile must not be disconnected. Apply a glass drill bit to cover the brick. Do not use a non-whole tile collage. This will not affect the personal safety during the installation or inspection. At the junction with the door and window, the edge of the door should cover the gap as much as possible.
16. Use dry white cement and talcum powder to clean joints within 1 hour after wall tiles are laid. After the inspection and acceptance, the joints shall be cleaned once and wetted with white cement and talcum powder to clean the joints.
17. Pay attention to product protection to prevent surface contamination and bruising.
Wall tile paste common quality problems and treatment methods Wall tile paste common quality defects are empty drum fall off, discoloration, seams are not flat and surface cracks.
1, empty drum off: The main reason is that the adhesive material is not full, the bricks are not soaked enough and the base layer is not processed. During construction, the glazed tile must be clean and soaked for not less than 2 hours. The thickness of the bond should be controlled between 7 and 10 mm and must not be too thick or too thin. When sticking, it is necessary to make the tile and the bottom layer stick densely, and there may be a wooden hammer that strikes. When hollow drums are produced, the wall tiles shall be removed to remove the original adhesive mortar and repaired with 107% cement mortar with a total volume of 3%.
2, color change: the main reason in addition to poor quality of the wall tiles, glaze over thin, the operation method is also an important factor. The material should be selected strictly during construction, and clean water should be used to soak the glazed tile. Paste cement mortar should use pure sand and cement. Always clean the remaining mortar on the brick surface during operation. If the color change larger wall tiles should be updated.
3, seams are not straight: The main reason is that there are differences in the specifications of bricks and improper construction. The tiles should be carefully selected during construction, and the same type of size should be used together for the same wall. The standard points must be set. The standard points should be based on the upper limit of the ruler. After each line is pasted, it should be immediately checked with the ruler horizontally and vertically. If the joints exceed the allowable error, remove the wall tiles in time for rework.
Acceptance Criteria:
1, the surface is clean, no scratches, uniform color, clear patterns, uniform seams, plate no cracks, lack of edge off angle and so on;
2. When the wall tiles are pasted, the flatness is checked with a 2M ruler, the flatness is ≤ 2mm, the gap width between adjacent ones is ≤ 1mm, the straightness is ≤ 2mm, and the difference between the heights of the joints is ≤ 0.5mm.
3, wall tiles must be firmly attached, no skew. Hollowing is controlled at 5% of the total, with no more than 10% of the empty area per sheet.
4. The yin and yang corners of the wall tiles must be checked to 90 degrees with a square. The corners of the wall tiles must be angled at 45°. The corners are tight and the gaps are continuous.
5, wall tiles cut switch socket position, the location must be accurate, to ensure that the switch panel installed after the cracks seam.
6. When the wall outlet of the brick wall is bored, the boring hole should be tight.
7. When the wall tiles are affixed, the intersection with the door opening shall be smooth and the gap shall be straight and even.

Marble Wall Construction Process and Quality Identification Marble wall construction is usually done by anchoring and grouting. The process flow is: primary treatment → drilling grooving → threading, tying reinforcement mesh → bouncing line → lining marble → grouting and sewing → waxing.
Identify the quality of marble wall should pay attention to the following points: 1 marble edges neat, no cracks and horns damaged; 2 marble plate and the base must be firmly bonded, grouting full and dense, not hollow, skew and warping. 3 The marble pattern is natural, the surface is smooth, the tone is harmonious, the caulking is tight, the joints are smooth, and the pattern is connected with the nature.
