Cement-based self-leveling system

Cement self-leveling, also known as cement-based self-leveling, is composed of special cement, carefully selected aggregates and various additives. When mixed with water, it forms a self-leveling foundation material with strong fluidity and high plasticity. It is suitable for precise leveling of concrete floors and all auxiliary ground materials, and is widely used in civil and commercial buildings. It features wear resistance, durability, economy, environmental friendliness (non-toxic, odorless and pollution-free), good adhesion, flatness and no hollowing. It has excellent fluidity, can automatically and precisely level the ground without increasing the elevation, and saves materials.

Construction Process
Process Name Specific Methods and Requirements Single Coat Usage (kg/m²)
Substrate Treatment The substrate must be clean, dry, and firm (strength > C20) with no structural defects. Grind the entire floor with a grinder, and repair cracked, peeling, or damaged areas. /
Applying Interface Agent Use WEDO-0801A cement self-leveling interface agent; apply evenly without gaps, and ensure no surface residual fluid. 0.20 
Cement Self-Leveling Construction Use WEDO-0802 cement self-leveling mortar:
1. Pre-mix cement first; with an electric mixer running, slowly pour the self-leveling cement into clean water in a suitable container. Stir continuously until a particle-free, uniform fluid mixture forms. Mixing ratio: 25kg self-leveling cement + ~6L water.
2. Pour the mixture evenly into the construction area, and spread it to the required thickness with a toothed trowel. Must be completed within 15 minutes.
3. Before the self-leveling mortar initializes, walk on the surface with special spiked shoes, and roll the floor with a bubble-removing roller to eliminate air trapped during mixing.
4. After 24 hours of construction, various floor materials can be laid or epoxy floors can be applied. 		8.5 (for 5mm thickness)
Topcoat Application Use WEDO-0801B cement self-leveling topcoat to seal the material’s pores; apply evenly with no gaps or accumulation. 0.10 
Protective Layer After the sealer dries, apply WEDO-0803 cement self-leveling polishing wax evenly. 0.10

Notes

  • Construction environment requirements: The ground should be dry, with a temperature not lower than 10℃, and the relative humidity of the ground should be maintained below 90%. There should be no rain or snow, and no overly strong through drafts to avoid premature local drying. If the summer is hot and the temperature is high, it is advisable to choose night construction.

  • Self-leveling land has relatively high requirements for the base layer. The base layer must not have loose concrete, grease, debris, and dust must be sucked clean. The floor drains, trenches, and division joints on the ground should be sealed with sponge strips first. The reserved joints of the original cushion layer should be sealed with the same material as the self-leveling mortar.

  • Before self-leveling construction, it is required that the surface of the interface agent be dry to achieve better connectivity. Attention should be paid to maintaining ventilation during construction. The interface agent is not freeze-resistant. When stored and transported at low temperatures, it should be kept warm.

  • It is best to use clean tap water for construction to avoid affecting the surface appearance quality.

  • Self-leveling floors must be constructed continuously without any breaks in between. The usage time after adding water is 20 to 30 minutes. Beyond this time, the self-leveling mortar will gradually solidify, develop strength and lose fluidity.

  • In cold conditions, stir with warm water (the water temperature should not exceed 35℃).
