How to conduct a comprehensive review of self-leveling
Construction technology
1. Check the ground humidity, confirm the ground dry; check the ground flatness, confirm the ground level; check the ground hardness, the ground should be no cracks.
2. Thoroughly clean the ground, remove all kinds of dirt on the ground, such as paint, oil and paint and so on. Fully polished the ground.
3. completely suck the dust.
4. The interface agent with a foam roller coating, 1: 1 watered, the amount per square meter is about 100-150 grams.
5. After the application of the interface agent, wait for 1-3 hours to maintain good ventilation, so that it is completely dry. And then self-leveling construction.
Self-leveling construction should pay attention to the three elements:
① humidity: ground moisture content should be less than 3% (self-leveling manufacturers require to keep the soil surface dry). Use CCM moisture tester.
② surface hardness: with a sharp chisel fast cross cut the surface, the intersection should not be burst. Use a hardness characterizer.
③ surface flatness: with 2 m ruler test, the gap should not be greater than 2mm. Use the flatness tester.
