Self-leveling floor is a one-component product prepared by the factory, including cement-based cementitious materials, fine aggregates and fillers, as well as other powder additives.
Construction technology:
1. Leveling treatment: the base level should be a smooth surface of cement powder or grindstone; Before construction, the construction site should be kept dry and clean.
2. Primer: It should be kept clean before construction. If any foreign matter adheres to it, it should be removed. The main agent and hardener should be mixed in the correct proportion and fully stirred.
3. Intermediate coating: it needs to be kept clean before construction. If there are foreign objects adhering, they need to be removed. The main agent and hardener should be mixed in the correct proportion and fully stirred.
4. Batch soil layer: evenly coat the material with a batch knife; According to the actual needs, the construction times should be smooth, without holes, batch knife marks and sanding marks.
5. Surface coating: evenly coat and mix the materials with roller or trowel, and the construction will be completed within 30 minutes.
Extended data:
Matters needing attention in self-leveling ground construction:
1. Confirm that the ground is dry, smooth and crack-free, and check the flatness and hardness.
2, clean up all kinds of dirt on the ground, such as paint, oil, paint, etc. It is necessary to grind the ground flat and suck off the dust.
3. Apply interfacial agent with foam roller, and add water according to the ratio of 1: 1, and the dosage per square meter is about 100- 150g.
5. After coating the interface agent, wait 1-3 hours, keep ventilation, ensure thorough drying, and then do self-leveling construction.
6. Stir with electric drill and cement slurry to form a mixture with uniform flow to ensure no caking. Then evenly pour the mixture into the construction area, evenly spread the self-flowing cloth with a rake, and roll it with a roller. Construction personnel shall ensure that the self-leveling cement mixing bag is completed within 15 minutes.
After about 7.24 hours, the self-leveling cement is completely dried, and the floor can be laid after 1-2 days.
