1, base cleaning
Before indoor ground construction, the surface of the structural layer should be strictly treated, and the floating ash, garbage and residual mortar on the surface of the base should be carefully removed. In particular, the surrounding walls and feet should be washed clean with water. If the bottom surface should not be too smooth during construction, it should be chiseled first if it is too smooth. If the base is too high, it should be chiseled first to make the surface layer uniform and convenient for construction.
Step 2 make a gray cake
Generally, the spacing between indoor ground ash cakes is within1.8m. Before making ash cakes, the grass roots need to be wetted, otherwise the ash cakes will fall off. The plastering thickness shall be determined according to the horizontal elevation of the wall surface around the room. After that, it will be watered for the second maintenance.
3. Soak water at the grass-roots level
The indoor ground shall be soaked at the grass-roots level in advance, and swept at the same time to avoid dust accumulation. Then brush it with pure water slurry prepared in advance.
4. Sweep the pulp:
Indoor ground should be washed clean at the grass-roots level first, and then brushed with pure cement slurry prepared in advance.
Step 5 scrape it flat
After the concrete is laid on the ground, it should be leveled. Float will appear in this process, so it must be scraped from the inside out.
6. Polishing and secondary leveling the disc.
After the above processes are completed, dry cement should be sprinkled on the ground, and the grinding process should be repeated before the cement absorbs water, and finally calendering should be carried out.
The slope of the floor must meet the design requirements, and the joint with the pipeline must be tight and flat to prevent water leakage.
In terms of materials, silicate cement or ordinary cabinet acid-base cement should be used for indoor floor cement, which has certain requirements for strength. Sand should be coarse sand or washed medium sand, and there are special requirements for the maximum particle size of sand. Stones are pebbles or gravel. According to the construction conditions, choose reasonable machines, tools, equipment and auxiliary tools to achieve their own goals and smooth construction.
