How to lay a concrete floor? Simple method of laying cement floors

Cement floors are self-leveling. Otherwise, after paving the floor for a long time, the sand under the floor will wear and leak the mat under the floor, which will directly lead to the damage of the back plate of the floor, resulting in the phenomenon of bulging on the surface of the floor, even if it is a small hole, it will also affect the beauty of the floor.

Self-leveling is a solvent-free, self-leveling, dense particle high-build epoxy floor coating. Self-leveling solves six major problems in floor installation. It is a kind of ground construction technology, it is a liquid substance mixed with water, after pouring into the ground, this substance can flow according to the unevenness of the ground, and automatically level the ground.

The application of self-leveling technology is first of all an innovation, the floor material in the liquid state will flow automatically after spreading to the ground, of course, this flow is not arbitrary, the liquid will automatically find the low-lying area on the ground and fill it, and finally the whole ground will flow into a mirror-like flat after static, condensation and solidification. The whole process does not rely on manual scraping.

When the ground is full of fine grains of sand, mud is placed on top of the sand, and the floor is placed on top.

If it is above the second floor, it is recommended to use composite flooring, the market price is generally 45-80 yuan per square meter (contracted labor and materials), the advantage is that it is easy to take care of, the cost is reasonable, and there is generally no problem with the use of 5 years!

If it is the first floor, it is recommended to use tiles, because the moisture is heavier, the use of wooden floors will be damp and mildew and even deformed, if you are not detailed, please ask!

The cement floor is treated like this before laying the floor:

1. Remove putty and latex paint that have fallen on the ground

During the renovation of the house, many people always put a lot of putty and latex paint on the floor. It is recommended that you buy some color strips on the floor while renovating so that you will not have as much trouble when you remove putty and latex paint.

2. Remove the putty residue at the intersection of the ground and the wall, as well as the loose part of the edge of the putty

Usually when we are scraping putty, the crew will only scrape them from the ground to about the height of the baseboard. Therefore, a wall blocked by a baseboard is usually not a putty. It is recommended that when performing wall treatments, the staff needs to install the scraper putty to the bottom of the wall.

3. Clean the dust on the ground

If some small dust on the floor is difficult to remove, you can use a latex paint brush to brush all the edges of the walls. You can brush out the tiny dust on the wall and clean it. It is also important to clear the ground with a mop. Use a mop to clean the floor so that the floor is free of dust.

4. Close the construction site before entering the wooden floor to prevent dust pollution

Then we need to seal the floor and wait for the floor to be laid. If we don't leave the floor for a long time, we need to remove the surface dust before laying the floor.

Precautions

1. Install the floor first and then the door

The general sequence of floor installation is that the floor is installed first, and then the door. If you need to install the door first, you should leave the height of the ground in advance, which is calculated as the thickness of the floor, the thickness of the floor mat in mm, and the thickness of the gusset (depending on the material).

After the floor is bought home, it is best to store it in the room for 2 days and then pave it if there are conditions to adapt to the customer's home environment. Wood floor paving is greatly affected by the climate, and try to avoid construction under the harsh climatic conditions of high temperature, rain or continuous cloudy days.

2. Complete professional tools

Floor installation needs to be equipped with professional construction tools, each tool has a different functional purpose, and the floor loss rate and cutting accuracy are affected by the construction tool to a certain extent. Whether professional tools are matched has become an important basis for measuring the professional level of service of flooring manufacturers.

3. The ground level must meet the standard

Ground flatness plays a decisive role in the effect of floor installation, uneven ground may cause the floor to be suspended, the floor cracks, the floor has a sound, affecting the use of the floor effect and life, the national standard stipulates that the ground flatness should meet the pavement requirements.

Use a 2m ruler to detect the flatness of the ground, the maximum chord height between the ruler and the ground should be 5mm, in order to achieve the best installation effect, some floor manufacturers will raise the enterprise standard to the maximum chord height should be 3mm, and provide consumers with self-leveling base leveling services.

How to lay the floor on the cement floor is as follows: 1. Clean the dust and dirt on the original cement floor.

2. Wet the cement floor. 3. Prepare the cement mortar according to the correct modulation ratio, and it needs to be stirred evenly. 4. Use a scraper to lay the prepared cement mortar on the cement floor, and the surface of the cement mortar must be kept flat.

5. Lay the floor tiles on the cement mortar. 6. Use a rubber hammer to vibrate the floor tiles, and in the process of compaction, the strength should not be too large, otherwise it is easy to cause the floor tiles to crack. 7. Set up the floor tiles at one time according to the correct order.

Once you've finished laying it, just wait for the tiles to dry naturally. Hope mine can help you <>

Do you have any other questions?

1.Unlike other flooring materials, cement floors must be kept moist when laying them. Therefore, before starting the construction, we must sprinkle water evenly on the ground so that the ground is completely wet.

Only in this way is the cement less susceptible to cracking because it is too dry in the subsequent process. Some friends ignore this, and in the end, due to insufficient draft, the adhesion between the cement and the base layer is greatly reduced.

2.Before laying the cement floor, we also need to prepare, that is, with cement. Maybe some friends don't know that cement is not directly used.

It needs to be mixed with sand in a certain proportion to form the cement that we often use. So what's the ratio? In general, the ratio of cement to sand is about 1:

5。This is the best ratio of sediment, so that the cement effect of mixing is the best.

3.After completing the above two steps, we can start to stir the mortar. When mixing mortar, the uniformity of the mortar must be ensured, and there must be no local thickness and local thinness, because this is related to the use of mortar.

If the mortar is mixed unevenly, the laid ground will be uneven. If the ground is uneven, it will be serious to carry out the later steps.

4.After laying the mortar, we need to level the ground. The main purpose here is to compensate for some of the problems caused by the depression of the ground and to level the laid concrete floor.

Usually, cement scraping tools are used for one-way construction. In this step, it must be noted that leveling should be completed before the mortar solidifies, otherwise the mortar will not be able to be carried out after solidification. Only by leveling the ground can the problems caused by the depression of the ground be compensated.

5.The final step is to maintain the concrete floor. Generally speaking, after the cement floor is laid, it needs to be watered two or three times a day to make the cement floor dry naturally.

In addition, if we want the cement floor to have a light transmission effect, we also need calendering. This step can only begin after the cement floor has dried and cured for four or five hours. By calendering, the concrete floor will have a light transmission effect.

First of all, you have to buy some dirt and bring it back, then put the soil in the water, and finally stir it for about 20 minutes, so that the cement for the floor is made.

It needs to be matched with sand, 325 cement, ordinary cement, sand, according to the ratio of 1:2:5, stirred, so that it is okay, add some water, you need to stir evenly.

Buy *** limestone and crush it, then put it in the barrel, add water, iron ore and other materials, and stir it according to the proportion.

Add water to cement and put sand and mix these together, so that the cement is ready.

1. Different from the laying of other ground materials, when we lay the cement floor, we must keep the ground moist, so before starting the construction, we must evenly sprinkle water on the ground to make the ground completely wet. Some friends ignore this, and finally because the draft is not enough, the adhesion between the cement and the base layer is greatly reduced.

2. Before laying the cement floor, we also need to make a preparation, that is, with cement. Some friends may not know that cement is not directly used in the package, it needs to be mixed with sand in a certain proportion to form the cement we often use. So what is this ratio?

Generally speaking, the ratio of cement to sand is about 1:5.

3. After completing the above two steps, we can start to stir the mortar. When stirring the mortar, we must ensure the uniformity of the mortar, and do not appear thick in some places and thin in others, because this is related to the use of mortar. If the mortar is not stirred evenly, then the laid ground will be uneven.

4. After the mortar is paved, we need to level the ground, which is mainly to make up for the problems caused by some ground depressions, so that the laid cement floor is level. Generally, the cement scraping tool is used to construct in one direction. When carrying out this step, it is necessary to pay attention to the leveling before the mortar solidifies, otherwise there is no way after the mortar solidifies.

5. The last step is to carry out a field excavation and maintenance on the cement floor, which generally says that after the cement floor is laid two or three days later, it needs to be sprinkled two to three times a day to let the cement floor dry naturally. In addition, if we want the cement floor to have a light transmission effect, then we also need to calender it, and this step needs to wait for the cement floor to dry and solidify for four or five hours before starting.

Enter the area and get the decoration for free**].

We bought the house and when we got the keys we were ready to renovate. Decoration can be said to be a major event in every family, some people will choose to use cement to decorate the floor when choosing to decorate, so how to decorate the cement decoration floor? Let's take a look at it together.

1. The construction of the concombustible cement floor is different from other ground construction. Before construction, sprinkle some water on the ground, so that the ground can eat through the water and then cement on it, so that the cement floor is not easy to crack; If there is not enough water, it will affect the adhesion between the cement and the base layer. 2. Cement is not used directly, it should be mixed with sand in a certain proportion, only the correct mixing ratio is not easy to crack; If the mixing ratio is relatively low, the cement floor will appear ash or sand return.

Therefore, when we mix, the ratio of cement to sand is between 1:4 and 1:5; If the sand used at home is relatively fine, the mixing ratio should be larger.

3. Stir the mortar evenly, and always observe the viscosity of the mortar, because the mortar with different viscosity has a great impact on the effect of cement after curing. Where thick mortar is used, the cement surface shrinks less; Where thin mortar is used, it is easy to produce errors in height, resulting in uneven ground conditions; Therefore, mixing mortar is an important step in the construction process. 4. If there is a height difference on the ground, we must carry out the smoothing work before the cement is dry.

Because it takes time to measure the height difference, we have to pull the line when the cement has just begun to solidify, and the whole leveling process must control the time, **uneven compensation**. 5. After the ground is paved, we have to carry out certain maintenance work. After the leveling is over, you can do not need to sprinkle water for two to three days, and then sprinkle water two to three times a day, so that the cement will dry naturally so that there will be no cracking.

6. Calender the cement floor. In order for it to have a translucent effect. Wait for the concrete floor to dry and solidify for four to five hours before you start working.
