How To Renovate The Old Cement Floor:

1. Use a professional floor grinder, install the grinding discs, and grind the ground. Remove all the sand from the surface to reveal smooth and firm aggregates. 2. With the sealing curing agent, sprinkle it on the ground, let it fully absorb until it is saturated, which can increase the strength of the cement floor. 3. If the cracking of the cement floor is serious, first roughen the floor, and then rinse the floor with a water gun.

What Is Cement Floor:

1. Construction joints shall not be left in the laying of the cement concrete surface. When the construction gap exceeds the allowable time, the joints should be treated. If the concrete floor is seriously sanded and ash, the water grinding machine should be installed with a diamond grinding block first. The purpose is to smooth the ground, remove the glue, paint, plain cement slurry and other attachments on the ground, and then assemble the diamond grinding block with a water grinder to grind the ground to further improve the smoothness and flatness of the cement ground, remove the surface and mud, and dry the ground..

2. Expansion joints should be set at 6m × 6m for the cement concrete surface. Expansion joints should also be set at structural changes. The sandy cement floor should be cleaned to ensure that the surface is free of dust. Keep the cement floor dry and free of open flames. Where there is a defect, it should be filled first to increase the hardness and wear resistance of the damaged part, and then repaired with 302N high-strength repair material, and then carried out an enhanced wear-resistant treatment.

3. Sand should be medium sand or coarse sand, and the mud content should not exceed 3%. During the constant temperature period, the internal temperature of the concrete should not exceed 60 °C, and the maximum should not exceed 65 °C. The constant temperature curing time should be based on the demoulding strength requirements of the components and the concrete mix ratio. The conditions and environmental conditions are determined by testing.
