How to do a good job on the wall when the level of leveling work
With a thin paper to protect the wall can be self-leveling construction
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.
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.
6. If it is a commercial self-leveling cement (25 kg) a bag should be poured into a 6 kg of clean water in the mixing bucket, if it is super self-leveling (25 kg) a pack should be poured into 6.5 kg of clean water Stir the barrel, with a pulp drill to stir until the formation of uniform flow of the mixture. Must ensure that no caking. And then quickly mix the mixture into the construction area, with a rake will be uniform gravity cloth, and roll with a roller, the air release. Pay attention to the reasonable arrangements for the construction staff to ensure that within 15 minutes will be a good mix of a pack of self-leveling cement construction. Complete 2 mm thick, each pack can be coated about 8 square meters.
7. After about 24 hours, self-leveling cement is completely dry, 1-2 days after the floor laying. Note:
Ground temperature below 5 degrees can not be self-leveling cement construction. The above-mentioned drying time is applied at room temperature of 20 ° C under normal conditions. This drying time will be extended due to low temperature and high humidity.
