How to renovate the old cement floor

 How to renovate the old cement floor:

1. Use a professional floor grinder, install the grinding disc, 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.

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 clean the ground. Let the ground dry for using.


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 again to enhance the wear resistance.

3. Sand should be medium sand or coarse sand, and the mud content should not be greater than 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.

What is epoxy terrazzo floor and epoxy terrazzo floor’s application and construction process

Image
Epoxy terrazzo floor , also called epoxy-based terrazzo floor, or organic terrazzo floor . It is suitable for shopping malls, exhibition halls, corridors, high-level entertainment venues, exposition halls, business clubs and other places that require beautiful and wear-resistant floors. A good-quality epoxy terrazzo floor needs to meet three conditions: Firstly, the surface is smooth and flat, without wear lines, blisters, cracks, and aggregates are evenly exposed, and the grid is firm; Secondly, the surface layer slope is designed reasonably and will not appear the situation of running water backflow; Thirdly, is that the heights of the skirting lines are the same, and the thickness of the constructed sample is uniform and there is no hollow. The construction process of epoxy resin terrazzo floor: 1. Basic cleaning In order to prolong the service life of the floor, make the flatness of the base layer meet the standard, and lay a good foundation for the subsequent coating const...

How to polish the cement floor?

Image
1. Construction technology of cement floor polishing and grinding 1. Base surface treatment: use a refurbisher to remove the loose surface layer, and the empty drum part will be treated separately. 2. Damage repair: Use repair materials to repair. 3. Leveling: use a floor refurbishment machine to add floor grinding discs (water grinding or dry grinding); 4. Coarse grinding: Use No. 50-200 floor grinding disc (water grinding or dry grinding). 5. Penetration treatment: use concrete sealing curing agent to harden. 6. Fine grinding: Use No. 200-300 floor grinding disc (water grinding or dry grinding). 2. The operation and construction method of cement floor 1. The grinding machine used for grinding grinds the cement floor, mainly to remove the dirt, paint and glue on the ground to repair the smoothness of the surface. The reason is that the cement floor hardener is a functional coating, which can be strengthened, but there is no way to produce new features, which should be trimmed prior ...
