Wall tile paste is one of the main technical tasks that bricklayers are engaged in in home decoration projects. The paste procedure of the wall tile specification is: base layer cleaning treatment → smear ash → brick selection → soaking → brick splicing → elastic line → paste standard point → paste tile → joint seam → wipe seam → clean.
First, the construction specification of wall tile paste
1. When the base layer is treated, all kinds of dirt on the wall surface should be cleaned and watered and moistened one day in advance. If the base layer is a new wall, when the cement mortar is 70% dry, it should be arranged for brick, bullet and paste.
2. The standard point must be pasted before the official paste to control the flatness of the pasted surface. The flatness should be checked by the ruler at any time during operation. If it is uneven or not straight, it should be removed.
3. Before the tile is pasted, it must be soaked in clean water for more than two hours. Take the brick body without bubbling, take it out and dry it for use. Paste from the bottom to the top when pasting, requires the mortar to be full, when the ash is lost, it must be removed from the sticky, and it is not allowed to fill the ash from the brick joint or the mouth.
4. When encountering the pipeline, the switch of the lamp, the support of the bathroom equipment, etc., it must be cut and matched with the whole brick set, and it is forbidden to use the non-whole brick to piece together. The whole or separate parts should be pasted one at a time. When the one time cannot be completed, the joints should be left at the construction joint or the corner of the corner.
Second, the wall tile paste acceptance wall tile must be firm, no skew, missing corners and cracks and other defects.
The wall tile paving surface should be smooth, clean, color coordinated, reasonable pattern arrangement, no discoloration, basal alkali, stains and significant gloss damage. The brick joints are densely packed, straight, uniform in width and uniform in color, and the overlapping direction is true at the yin and yang angles. Non-whole bricks are used properly and arranged in a straight line. The reserved holes are the correct size and the edges are neat. Check that the flatness error is less than 2 mm, the vertical error of the facade is less than 2 mm, the height deviation of the joint is less than 0.5 mm, and the flatness is less than 2 mm.
Third, wall tile paste common quality problems and treatment methods
Common quality defects in wall tile paste are empty drum peeling, discoloration, uneven seams and surface cracks.
1. Empty drums fall off: The main reason is that the bonding materials are not full, the bricks are not soaked enough, and the base layer is not clean. During construction, the cuff tiles must be clean and clean, immersed for not less than 2 hours, and the bond thickness should be controlled between 7-10 mm, not too thick or too thin. When pasting, make the tile and the bottom layer densely glued. You can tap it with a wooden hammer. When the empty drum is produced, the wall brick should be removed, the original bonding mortar should be shoveled, and the cement mortar with the total volume of 37 glue should be used for repairing.


2, color change: the main reason in addition to the poor quality of the tile, the shaft surface is too thin, improper operation methods are also important factors. Materials should be strictly selected during construction, and clean water should be used for soaking the cuff tiles. Pure cement and cement should be used for the cement mortar to be applied. Always clean the mortar remaining on the brick surface during operation. Wall tiles with larger color should be updated.


3, the seam is not straight: the main reason is the difference in brick specifications and improper construction. During the construction, the tiles should be carefully selected and the same size should be put together for one wall. The standard point must be attached. The standard point should be based on the ruler. After each line is pasted, it should be checked in time by the ruler horizontally and vertically. If the seam exceeds the allowable error, the wall tile should be removed in time for rework.


4. Estimation of the construction period of the wall tile paste


   Wall tile paste is a highly technical construction project, which is relatively labor-intensive. Under the condition that the auxiliary materials are prepared and the grassroots treatment is better, each worker can complete about 5 square meters a day. The general home decoration is paved with a bathroom and kitchen wall. It takes about 7 days. The different specifications of the ceramic wall tiles, the different binders used, and the difference in the number of base wall pipes will affect the construction period. Therefore, the actual construction period should be determined according to the site conditions. Paste construction of wall tiles can be parallel or cross-work with other items, but attention should be paid to finished product protection.
