The common quality defects for wall tiles are emptying, discoloration, uneven seams 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.
, Joints 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.
Remarks: Construction Process and Quality Identification of Marble Wall
Marble walls are usually made using anchoring and grouting methods. 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.
