Before the ground is paved, it is necessary to do a good job of ground leveling. Ground leveling is a relatively complex construction process, which must be constructed in accordance with the corresponding process to ensure the construction effect. Dazhou Luofu Forest will teach you how to do ground leveling for decoration.
1. Clean the surface.
Check the base layer, and there are no defects such as hollowing, shelling, peeling, loosening, pitting, cracks and so on. If there is, clean it all, remove the grease and other pollutants on the base with detergent, and clean up impurities such as dust, weak concrete surface, grease and so on, so that the base layer is dense and the surface is free of loosening and debris.
2. Elevation plastering cake.
The leveling thickness is determined according to the type and thickness of the ground decoration material and the standard line of the finished surface. Generally, the thickness of the surface plastering is not less than 20mm, and the leveling control line pops up on the wall. According to the leveling control line, spread the plastering cake around the wall. The size of the ash cake is generally 5x5cm, and the horizontal and vertical spacing is 15-2.0 meters. If the room is larger, rub the standard ribs. The mortar material mix ratio of the plastering cake and the standard steel bar is the same as that of the plastering floor.
3. Brush the cement slurry adhesive layer.
Doing this well will allow the cement mortar to be better combined with the ground. Cement slurry should be pressed 1:05 ratios. Once the preparation is complete, use a broom or other tool to brush to the ground to form a binder layer.
4. Lay the cement mortar surface layer.
After the cement mortar is painted, the cement mortar is sprinkled, and the mud mortar mix ratio is cement: sand = 1:2, and the mixture is even. Portland cement and ordinary Portland cement shall be used in the preparation of cement mortar, and its number shall not be less than 325mpa。Do not mix different varieties and grades of cement, and use medium sand to mix;The volume ratio of the screed mortar is 1:3, and the strength grade is not less than m15. The screed layer of the same room should be completed at one time, and no construction joints and joints should be left.
5. Calendering. When the cement mortar is slightly condensed in water, when a person steps on a footprint but does not sink, the cement surface is spread out and calendered with an iron trowel. Before the cement mortar finally solidifies, the first mortar is carried outSecondary calendering to flatten and compact the plastering pattern.
6. Maintenance. Sprinkle sawdust or other materials with water to keep them moist and prevent cracking. Wait until the compressive strength reaches 5MPa before entering. After that, it is good to take care of it naturally, mainly to avoid direct sunlight, strong winds, etc.
