What is the construction thickness range of cement self-leveling?

As an advanced floor leveling and decoration material, the construction thickness range of cement self-leveling is a key factor affecting the construction effect, floor performance and cost.
Generally speaking, the construction thickness range of cement self-leveling is relatively flexible, usually between 2 mm and 10 mm. In the thinner 2-5 mm thickness range, it is mainly suitable for places with high requirements for floor flatness and light load, such as floor renovation of family residences and fine leveling of some high-end commercial places. The thinner construction thickness can minimize the use of materials and reduce costs while ensuring the flatness and smoothness of the floor. For example, before laying wooden floors in the family living room, self-leveling construction is carried out. The thickness of 2-3 mm is enough to make up for the slight unevenness of the original floor, providing an ideal foundation for the installation of wooden floors, and will not significantly increase the height of the floor, avoiding subsequent problems such as affecting the opening and closing of doors.
When the construction thickness is 5-10 mm, it can be used in areas with certain requirements for load-bearing capacity or where the original ground condition is poor. In industrial plants, warehouses and other places, self-leveling layers above 5 mm can better withstand the heavy pressure of equipment and goods and the wear and tear caused by frequent traffic of people and vehicles. Self-leveling in this thickness range can effectively fill larger ground potholes and gaps, making the ground more solid and durable. For example, in some light mechanical processing workshops, 6-8 mm cement self-leveling can not only ensure the flatness of the ground to facilitate the precise installation and operation of the equipment, but also provide stable support with sufficient thickness.
However, the construction thickness cannot be set arbitrarily. A self-leveling layer that is too thin may not be able to completely cover the defects of the original ground, resulting in unsatisfactory surface flatness, and will also affect its strength and wear resistance, and it is prone to cracking, sanding and other problems. When the construction thickness is too large, on the one hand, it will increase the material cost and construction time, and on the other hand, because the cement self-leveling will produce a certain shrinkage stress during the curing process, the self-leveling layer that is too thick may produce cracks or even hollowing due to uneven shrinkage, which seriously affects the quality of the ground.
Therefore, when carrying out cement self-leveling construction, the construction thickness must be accurately determined based on factors such as the actual ground conditions, usage scenarios, and performance requirements, and the construction process specifications must be strictly followed to fully utilize the advantages of cement self-leveling and create a flat, solid, and beautiful high-quality floor.
