What is self-leveling

Self-leveling is to mix cement and water evenly and pour it on the ground, using its own fluidity to level the ground.

Its thickness is generally 2-4 mm.

Self-leveling construction usually includes the following steps: 01 Self-leveling construction—priming 1. Absorbent base layers such as concrete and cement mortar leveling layers should first be diluted with water in a ratio of 1:1 using a multi-purpose interface treatment agent and then sealed and primed.

.

2. For non-absorbent base layers such as ceramic tiles, terrazzo, marble, etc., it is recommended to use a dense interface treatment agent for priming.

3. If the moisture content of the base layer is too high (>3%) and construction needs to be carried out immediately, an epoxy interface treatment agent can be used for primer treatment, but the premise is that the moisture content of the base layer should not be greater than 8%.

4. The interface treatment agent should be applied evenly without obvious liquid accumulation.

After the surface of the interface treatment agent has dried, the next step of self-leveling construction can be carried out.

03 Self-leveling construction - laying 1. Pour the mixed self-leveling slurry onto the construction floor, scrape it slightly with the help of a special tooth scraper, and then use its own fluidity to level the ground.

2. Then the construction workers should put on special spike shoes, enter the construction ground, and use a special self-leveling deflation roller to roll gently on the self-leveling surface to release the air mixed in the mixing to avoid bubbles, pitting and joint height differences.

3. Please close the site immediately after the construction is completed. Walking is prohibited within 5 hours, and heavy objects should be avoided within 10 hours. PVC flooring can be laid after 24 hours.

4. During winter construction, floor laying should be carried out 48-72 hours after self-leveling construction.

5. If the self-leveling needs to be finely ground and polished, do it after the self-leveling cement is completely dry.
