1. For the detection of the ground at the grass-roots level, use a 2-meter ruler to detect the flatness of the ground, and use a scoring instrument to evaluate the strength and absorbability of the surface at the grass-roots level and whether there are cracks or holes at the grass-roots level;
2. Polishing the base, observing whether there is sand on the ground, removing substances with insufficient adhesion on the ground when necessary, polishing the ground, and vacuuming with a vacuum cleaner;
3. Before construction, the ground should be moistureproof, and the interface agent should be roller coated twice. Before the second roller coating, it is necessary to sprinkle quartz sand, polish and vacuum after curing, and the interval between the two roller coatings is between 12-48 hours to ensure the moisture-proof effect;
4. Then add water to the self-leveling cement in proportion and stir it evenly, pour it on the ground and brush it evenly with a scraper, with a thickness of 4-6 mm generally; 5. defoaming treatment is needed during construction to prevent self-leveling and cracking of cement shell;
6. Finally, the roll-coated waterborne polyurethane cover is wear-resistant and impervious.
What is a self-leveling floor?
Self-leveling floor is a kind of free-flowing slurry, which can change from material to water. According to the uneven terrain, it can be quickly spread on the ground to obtain a flat ground from the surface. Generally, ordinary silicon cement, high alumina cement and silicate cement are used as bonding materials for cement self-leveling floor.
What is self-leveling cement?
Special cement that can make clean slurry, mortar or concrete reach predetermined strength and compactness without vibration at low water-cement ratio. Self-leveling cement is a high-tech green product with high technology content and complicated technical links. It is a dry-mixed powdery material composed of various active ingredients, which can be used after being mixed with water on site. After a little spreading with a scraper, a flat base surface can be obtained. The hardening speed is fast, and you can walk on the floor in 4 ~ 8 hours, or carry out follow-up work (such as laying wood floors and diamond boards). The construction is fast and simple, which is incomparable to traditional manual leveling. Safety, pollution-free, beautiful, rapid construction and put into use are the characteristics of self-leveling cement.
Self-leveling cement is widely used in industrial workshops, workshops, warehouses, commercial shops, exhibition halls, gymnasiums, hospitals, various open spaces and offices. , also used in families, villas, warm small spaces, etc. Can be used as decorative surface and wear-resistant base.
