The paste quality of wall ceramic tiles directly affects the decoration effect, especially the paste quality of dark color sleeve bricks. The evaluation of the quality of home decoration is even more prominent. It must be constructed in strict accordance with the standard procedures to ensure quality.
When the owner accepts and pastes the good wall tiles, he or she should observe whether the wall tile paste is firm, with no skew, missing corners, and cracks. Wall tile paving surface should be flat, clean, color coordination, reasonable pattern arrangement, no discoloration, pan-alkali, stains and significant gloss damage. The brick joints are densely packed, straight, uniform in width and width, and uniform in color. The lap direction at the yin and yang corners is correct. Non-whole bricks are suitable for use and are arranged straight. The hole has the correct size and the edges are neat. Inspection flatness error is less than 2 mm, facade vertical error is less than 2 mm, seam height deviation is less than 0.5 mm, and flatness is less than 2 mm.
Then, what are the common quality problems of wall tile paste? How to solve the quality problems? The common quality defects of wall tile paste are empty drums, discoloration, uneven seams and surface cracks.
Empty drum fall off: The main reason for empty drum fall off is that the adhesive material is not full, the bricks are not soaked and the base layer is not treated properly. During construction, the bricks on the sleeve must be clean and free from immersion for not less than 2 hours. The thickness of the adhesive should be controlled between 7 and 10 mm and should not be too thick or too thin. When sticking, it is necessary to make the tile and the bottom layer stick densely. You can tap it with a wooden hammer. When hollow drums are produced, the wall tiles shall be removed, the original bonded mortar shall be removed, and cement mortar shall be used for repairing with a total volume of 3% of glue.
Discoloration: The main cause of discoloration is due to the poor quality of the tiles and the excessively thin shaft surface. The improper operation method is also an important factor. The materials should be strictly selected during construction, and clean water should be used for soaking the sleeve bricks. Adhesive 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 for this situation is the difference in brick specifications and improper construction. The bricks should be carefully selected during construction and the same kind of dimensions should be used together for one wall. The standard points must be posted. The standard points must be on the basis of the ruler. After each line is pasted, it should be checked in a timely manner by using the ruler horizontally and vertically. If the joints exceed the allowable error, the wall tiles should be removed in time for rework.
Wall tile paste is a highly technical construction project. It takes a lot of man-hours, and when the auxiliary materials are prepared and the grassroots processing is better, each worker can complete about 5 square meters a day. The general family decoration is glued to the bathroom and the kitchen wall. Face takes about 7 days. Different specifications of ceramic wall tiles, different binders used, and different number of basic wall pipes will affect the construction period. Therefore, the actual construction period should be determined according to site conditions. The paste construction of wall tiles can be used in parallel or cross-operation with other projects, but attention should be paid to the protection of finished products.
