In the home decoration, the construction standards for the wall and floor tiles, the common quality problems and treatment methods of the wall tiles, and the detailed description of the construction process and quality identification of the marble wall surface. The following content is organized by a senior designer of a decorative company to provide your reference.
1. Construction process
Base treatment → elastic line → wall tile paste → wipe seam → repair protection
2. Construction methods and technical measures
(1) Grassroots treatment
A. In order to strengthen the bonding between the tile and the substrate, the loose concrete and mortar debris of the wall should be cleaned up, and the obvious protruding part should be chiseled.
B. The bottom mortar should be absolutely flat, and the yin and yang angles should be absolutely square.
C. If there is oil on the wall, it can be cleaned with caustic soda solution.
D. Before the tile is laid, the surface of the base should be sprinkled with water and then smeared with 1:3 cement mortar.
(2) Elastic line:
According to the design requirements of the drawings, according to the arrangement of the door and window openings and the horizontal and vertical decorative lines, firstly, the details of the corners, wall sills, lines, compartments (or borders), windowsills, etc.
The treatment plan, pop-up control size, to ensure that the wall is complete and the parts are smoothly operated.
(3) Brick selection:
Out-of-the-box check on the incoming bricks. If the size and color are found to be different, it should be processed and added for full inspection.
(4) smear the ash:
Before the tile is laid, the surface of the base should be sprinkled with water and then smeared with 1:3 cement mortar. The bottom mortar should be absolutely flat, and the yin and yang angles should be absolutely square.
(5) Paste brick paste
A. According to the design elevation, a number of horizontal and vertical lines are popped up, and then the width of the divisional slit is determined according to the design requirements and the specifications of the tile, and the division grid is prepared, so as to be pasted according to the pattern features of the tile. The tiles should be soaked in water before being pasted. Generally, they should be soaked for more than 2 hours.
B. The face brick should be paved with cement slurry, generally from bottom to top, and the whole or separate parts should be completed at one time.
C. Before applying the bonding layer, brush the cement slurry on the wet bottom layer, and spread the tile on the wooden backing board (bottom side up), fill the seam with 1:2 dry cement sand, and clean the bottom surface with a soft brush. Thick sand, coated with a thin layer of cement mortar (1:0.3=cement: lime paste), and then pasted. After the flat brick of one unit is finished, after the mortar is first set and solidified, spray the protective paper with water to remove Before the initial setting of the cement slurry, use the metal paddle to adjust the gap between the bend and the twist to make the distance evenly. If there is a moving small piece of brick, the board should be tapped and tapped to compact.
D. After the final layering of the bonding layer is completed, the seam is flattened with a white cement thick paste, and the seam is pressed hard to make the gap full and dense, and covered with a plastic film after completion.
3. Quality standards:
(1) The tile and the base layer must be firmly adhered and there is no empty drum phenomenon.
(2) The surface is flat, clean, free of skew, lack of ribs and corners, and defects such as cracks, basal alkali, stains, and gloss. Tiles should have no visible color difference.
(3) Tile joints should be dense, straight, wide and narrow.
