How to renovate the old cement floor, how to renovate the old cement floor indoors

Cement floor is a very common ground material, the construction of cement floor is relatively easy, cement floor is more wear-resistant, corrosion-resistant, but it will also cause problems after long-term use. After the problem of the cement floor, we need to repair and renovate the cement floor, and the common old cement floor repair and renovation are as follows.

1. Cement floor repair and renovation for concrete infiltration floor.

Cement floor repair and renovation to concrete infiltrated floor is currently the most commonly used renovation method, and it is also the most economical method. By sanding and renovating the original cement floor, then spraying concrete sealing curing agent to plug the pores in the concrete, and increasing the hardness, wear resistance and brightness of the concrete, finally the old cement floor becomes an attractive glossy floor like marble. After the transformation, the ground not only gets rid of the ash, sand, oil stains, cracks and other drawbacks of the ordinary cement floor, but also dustproof, pollution-proof, easy to clean, increases the hardness and wear resistance of the ground, and has a service life of more than 20 years.

This is one of the most economical ways to renovate a concrete floor.

2. Cement floor repair and renovation for epoxy and polyurethane flooring.

Epoxy flooring, polyurethane flooring due to rich and beautiful color, wear resistance, pressure resistance, waterproof, anti-corrosion, sterility, cleaning, convenient construction and other factors have become the first choice for industrial and commercial flooring, after the ground is polished and renovated, and then coated with epoxy floor paint, polyurethane floor paint, in order to convert the concrete floor into epoxy floor or polyurethane floor, which is undoubtedly the best way to cover the old concrete floor.

3. The cement floor is repaired and renovated into a wear-resistant floor.

Wear-resistant flooring is divided into metal wear-resistant flooring and non-metallic wear-resistant flooring. Due to its smooth surface, wear-resistant, scratch-resistant, good gloss, rich color, has become one of the preferred floors in many machining, automobile manufacturing, parking lots, loading workshops, warehousing fields, the construction method is to first use milling machines, shot blasting machines, etc. to rough the original cement floor, and then pour a certain thickness of fine stone concrete, and then collect it, spread wear-resistant aggregate, and finally polish it.

Yes, the old cement floor. Be sure to remove the smooth part of the original surface. And be sure to use cement with a higher grade than the original cement. and diluents. That's how it goes. Make the cement floor more stable.

After the cement floor is repaired, sanded, dusted and other cleaning treatments, it is considered to be a wear-resistant and pressure-resistant epoxy floor.

The steps to renovate the old cement floor indoors are as follows:

1. When the old cement floor is renovated, first of all, all the original glue cement will be removed, and then the surface will be changed to concrete to penetrate the level, this method is used by many people, because it is more economical.

2. Polishing the original cement floor, repairing the cracked place, and then spraying some concrete sealing curing agent, at this time, the curing agent will play a role in blocking the capillary pores of the concrete, and at the same time increase the strength, wear resistance and brightness of the concrete, and finally turn the original old ground into a very smooth concrete level, and its service life is very long, basically there is no problem with 20 years of use.

3. The renovation of the cement floor, in fact, you can also choose epoxy, the floor epoxy floor, the brush on the cement is also very bright and good-looking, and its waterproof performance, anti-corrosion performance is very good, the method is very simple, only on the old cement, directly coated with epoxy.

4. Before coating, we must clean the surface of cement, the surface of cement, there can be no dust, and other rooms, if there is cracking, we had better use a sealing curing agent, seal all the places that have been opened, and then use epoxy, this situation will appear epoxy flooring.

When the old cement floor is renovated, the ground is first polished with a grinder, the surface is polished and smoothed, and the concrete aggregate is removed. For the renovation of old cement and old epoxy flooring, you can use Runyu new material flooring.

When the old cement floor is renovated, it is necessary to remove all the original cement, and then change the surface to concrete infiltration floor, which will be closer to affordable; To remove the old floor first, and then remove the grease, and then there are cracks to repair the treatment, when choosing the material, you can choose the concrete repair agent, it will be more convenient.

The original cement floor needs to be cleaned up, and the polishing and smoothing shall prevail; It is more common for old cement floors to be repaired and renovated into penetrant floors, and the original cement floors are cleaned and then coated with oily one-component floor penetrants.

The treatment method for the renovation of the old cement floor is as follows:

First, use a grinding machine to polish the ground, polish its surface flat, and remove the concrete aggregate. Then sprinkle the curing agent on the polished ground to improve its strength and prevent the phenomenon of ash or sand. Then select the corresponding grinding disc and continue grinding.

Finally, it is enough to remove the residual curing agent on the ground.

Maintenance method of cement floor

1. After the cement floor is paved and constructed, it must be maintained immediately. If the ground is paved mechanically, it must not only be sprayed with a curing agent, but also covered with a moisturizing surface.

2. When the cement floor is maintained, if it is rainy or when the maintenance water is sufficient, you can choose to use the leakage retention ruler wet film, sack or geomat to cover the maintenance, but you can not choose to use the water to maintain.

3. In the process of curing the cement floor, it is necessary to pay attention to the problem of time, which must be determined according to the growth rate of the compressive strength of the ground. This strength can not be below 80% of the design strength, and special attention should be paid to the maintenance of it in the first 7 days, and the moisturizing and thermal insulation must be done.

4. Under normal circumstances, the curing time of cement floor is about 14 days to 21 days. If it is in a high temperature environment, then the curing time should not be less than 14 days, but if it is in a low humidity environment, the curing time should not be less than 21 days. In addition, for the cement soil mixed with fly ash, it is necessary to pay attention to the replacement during the curing process, and the curing time cannot be less than 28 days.
