The paste of wall ceramic tile is one of the main technical tasks that tiler is engaged in home decoration project. The standard ceramic tile paste procedure is as follows: grassroots cleaning → wipe base ash → brick selection → immersion → row bricks → bullets → paste standard points → paste tiles → sew → sew → clean.

The paste quality of wall ceramic tiles directly affects the decoration effect, especially the paste quality of deep 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.

2. Construction specifications for wall tile paste

(1) When processing at the grassroots level, 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.

(2) The standard points must be pasted before the official paste to control the flatness of the paste surface. At any time during operation, the flatness should be checked with a ruler. If it is uneven or not straight, it must be removed.

(3) Tiles must be soaked in clean water for at least two hours before they are affixed. Tiles should not be bubbling and should be removed for drying. Paste from the bottom up paste, requiring mortar full, ash, must remove the heavy sticky, not allowed from the brick joints, mouth ash filling pad.

(4) When it comes to sticking, it encounters pipes, lighting switches, and supports for bathroom equipment, etc. It must be cut and matched with the entire brick set, and it is forbidden to put together and paste with non-complete bricks. The whole or independent part of the paste should be completed at one time, and once it cannot be completed, the joint mouth should be left at the construction joint or the female corner.

3. Acceptance of wall tile paste

The wall tiles must be firmly bonded without any defects such as 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.

4. Wall tile paste common quality problems and treatment methods

The common quality defects of wall tile paste are empty drum fall off, discoloration, uneven seams and surface cracks.

(1) Empty drum fall off: The main reason is that the adhesive material is not full, the bricks are not soaked enough, 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 and the original adhesive mortar shall be removed. The cement mortar shall be repaired with a total volume of 3% 107 glue.

(2) Discoloration: The main reason is that in addition to the poor quality of the ceramic tile, the axial surface is too thin, 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. 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) Joints are not straight: The main reason is that there are differences in the specifications of bricks 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.

5. Wall tile pasting period estimate

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.
