Self-leveling refers to a type of compound or material that is used to create a smooth, level surface. These products are often used in construction and renovation projects to level out floors, countertops, and other surfaces that may be uneven or have slight imperfections. Self-leveling compounds are typically made from a mixture of cement, sand, and a liquid bonding agent, and are applied in a thin layer to the surface to be leveled. The compound then hardens and dries to create a smooth, level surface that is ready for further construction or finishing. Self-leveling compounds can be applied to a variety of surfaces, including concrete, wood, tile and vinyl flooring
There are cracks on the cement self-leveling surface. There are many reasons for this phenomenon, including the problems of base course, construction, materials and maintenance. The main problems of the base course are serious sanding on the ground, low strength of the base course, cracking of the base course, hollowing, and cracking after heavy pressure;

During the construction, too much water is added to the cement self-leveling, the base layer is not cleaned, and the interface agent is improperly used, resulting in too fast surface water loss, dry shrinkage cracks, rapid water loss, insufficient cement hydration reaction, and surface pulverization; Improper later curing will also cause swelling and cracking.
The bigger the construction thickness, the greater the accumulated pressure, and the greater the risk of bulge and crack. Within the construction thickness of 5.0mm, the internal stress caused by this expansion and contraction is not enough to cause direct bulge.
Some self-leveling cement with a thickness of more than 5.0mm has the risk of cracking and bulging, which is caused by self-leveling shrinkage and expansion, and the construction unit does not know the harm of shrinkage and expansion.
For sanded ground, some construction units said that the surface should be coated with a layer of construction glue and cement to ensure that there is no problem. In fact, one layer of mortar has no effect. The heave of the swing layer will inevitably cause the heave of self-leveling.
