1. Construction Procedures for Floor Stones and Porcelain Tiles Floor stone and porcelain tile paving are the technical tasks frequently employed by tilers in home renovation. The standard procedures for stone paving on the ground are: sweeping and finishing the grass-roots level → cement mortar leveling → high calibration, elastic line → installation of standard blocks → selection of materials → infiltration → pavement → pouring and cleaning → maintenance and delivery.
Floor stone and porcelain tile paving is a highly technical project. Its construction quality has a great impact on the quality of the entire home improvement project. It is a key project of the entire project and must be constructed in accordance with standard procedures to ensure quality.
2. Specification for construction of ground stone and porcelain brick
(1) The grassroots treatment should be clean, and the leveling and repair should be done first. Before leveling the mortar, the ground should be sprinkled with water to improve the bonding ability with the base layer.
(2) Paving stones and porcelain tiles must be placed in standard blocks. The standard block should be placed at the crossing point of the cross line and installed diagonally. When paving, each line must be hung in sequence. The stone must be soaked in water, and the back of the stone must be wiped clean. When paving, retreat from the middle to the four sides of the pavement. When placing the stone and porcelain bricks, they must fall at the same time in four corners, and use a rubber mallet or a wooden hammer to hit the compaction.
(3) The maintenance of stone and porcelain tiles after pavement is very important. After 24 hours of installation, they must be sprinkled and watered, and they are forbidden for two days. In order not to affect the construction of other projects, solid wood panels can be laid on the ground for people to walk.
3. Acceptance of ground floor and porcelain tile pavement
The ground stone and porcelain bricks must be firm, the surface of the pavement is smooth, the color is harmonious, and the color is obviously poor. The joints are straight, wide and narrow, and the stone is free from nicks and corners. The non-standard size sheet pavement is correct and the flow direction is correct. The error of the cable inspection is less than 2mm. The error of the flatness is less than 1mm with a 2-meter ruler and the surface is clean.
4. Common quality problems and treatment methods for ground stone and porcelain brick pavement Common defects of ground stone and porcelain brick pavement are large deviations of empty drums and flatness.
(1) Hollowing: Mainly due to thin mortar in adhesive layer, dry cement paste in pavement, and sheet back; surface pollutants have not been removed, and people have walked or weighed during the curing period. In the construction, the adhesive layer mortar should be dry, and the floor spread should prevail. The water-cement ratio of cement slurry is 122.2 (volume ratio) when paving, and it is forbidden to use cement flour for laying. During the conservation period, shelves should be erected and walking on the surface is prohibited. If hollowing occurs, the rework should be reworked by removing the empty drum plate, sucking it with a suction cup, lifting it flat, and then paving according to the specification.
(2) Large deviation of flatness: In addition to improper construction operations and the fact that the board surface is not flat, the main cause is warpage of the board. In the construction process, strict selection of materials should be adopted, and those with serious warping and unqualified products with uneven thicknesses should be adjusted and leveled on the back of the board. For large local deviations, they can be smoothed with a marble machine and then polished. If there is no flat plate, remove it.
5. Estimated construction period of ground stone and porcelain tile pavement
Floor stone and porcelain tile paving are construction projects with high technical and labor intensity. Generally, the paving of the ground stone is carried out on a premise that the ground floor has been processed and auxiliary materials are available. Every worker lays about 6 square meters on a daily basis. If we add the initial grassroots treatment and post-patch conservation, each worker actually paves about 4 square meters per day. The paving period of floor porcelain tiles is slightly less than one day from the stone paving of the ground. If the ground is flat and the quality of the plates is good and the specifications are large, the construction period can be shortened. Under the condition of finished product protection, floor covering can be operated in parallel with paint construction and installation.
