How to level the uneven cement floor, what to do if the cement floor is uneven

Methods of leveling cement floors:

Elastic leveling control line: Determine the leveling thickness according to the type and thickness of the ground paving decoration material and the standard line of the finished surface, and pop up the leveling control line on the wall.

Do the plane elevation mud cake: make the mud cake along the wall according to the leveling control line, and pull the line to make the middle ash cake according to the height of the ash cake on both sides, and the ash cake spacing is not more than 1500.

Cement slurry bonding layer: Prepare plain cement slurry according to the ratio of 1:, sweep the ground with a broom to form a bonding layer.

Root bandaging or barrier protection of indoor facilities: bandaging the roots of completed wood products, bandaging the roots of the original indoor facilities or using materials to block them.

Cement mortar full spread: cement mortar mix ratio is cement: sand = 1:2, should be stirred evenly. After the cement mortar is fully paved, it is flattened with a long wooden pole to make the mortar and the base layer dense.

Surface calendering: Surface calendering is performed in two stages. For the first time, the cement mortar condenses slightly against water, and there are footprints when people step on it, but when it does not sink, after sprinkling the cement surface dry, calender with an iron trowel, from the corners to the large surface, the order is compacted and trowel, and the second calendering is carried out before the final setting of the cement mortar, and the trowel left by the first calendering is flattened, compacted and calendered with an iron trowel.

Watering curing: After 24 hours of calendering, the surface layer is covered with water-absorbing materials, and the water is not less than 2 times a day to keep the covering material moist, and the curing time is not less than 7 days.

1. Materials and accessories are needed to do ground self-leveling and leveling projects

1) Self-leveling materials;

2) interface agent;

Second, the construction time depends on the site area of the site, and after the construction is completed, it needs to be diluted for 48 hours to allow the ground to be completely dry before it can be put into use.

3. The construction budget of self-leveling and leveling is mainly based on the construction and materials used in each urban area. The common ones in Guangzhou are generally around 25-30 yuan.

Real shooting to do cement mortar ground leveling.

When decorating, ground decoration is a key task, which not only requires beauty, but also requires a certain practicality. For the cement floor, it is easy to cause uneven problems, which may lead to a series of troubles in the later stage, what is the reason for the uneven cement floor? And what is the best way to deal with it?

1. Reasons for uneven cement floors.

1. If the cement floor is uneven, it has a great relationship with the consistency of the mortar, and if the mortar is more viscous, it will lead to unevenness in the back of the cement floor.

2. Another possibility is that the process is incorrect when laying, for example, we have to calender after laying cement mortar, but the calendering time should be well controlled, too early and too late will lead to the problem of uneven cement floor.

3. Maintenance is also very important, if the maintenance is not done properly, it will lead to the rapid dehydration of the cement that has just been laid, which will lead to insufficient strength, and its ground will have potholes and unevenness.

4. Sometimes it will be directly manifested as the problem of hollowing on the cement floor, mainly because the ratio of cement mortar is incorrect, and the surface base layer is not cleaned, which will lead to insufficient adhesion, which will lead to hollowing on the surface.

Second, how to deal with uneven cement floors.

1. If the ground is uneven, we can do a leveling treatment, and we can also increase the hardness of the ground. There is a sealing curing agent for concrete, which can be poured directly on the ground and then sanded with a grinder. During construction, the ground can be made into a hardened floor, so that the drop of the ground becomes smaller, and finally the concrete is poured, and the leveling is done, and after reasonable maintenance, a certain effect can be achieved.

2. This curing agent can make the hardness of the ground meet certain requirements, and can maintain a certain brightness, the service life is relatively long, and it can also prevent sand from appearing in the later stage, and the surface is easy to clean and maintain, so it is a more popular way to treat the ground.

Summary: If the cement floor is uneven, it is also caused by many reasons. At the beginning of construction, we must pay more attention to every detail, so as to avoid uneven problems in the later stage.

According to the ground to pave the type of decorative material thickness and self.

The thickness of the surface plastering is not less than 20mm, and the leveling control line is popped up on the wall.

According to the leveling control line along the wall around the plastering cake, the size of the ash cake is generally 5x5cm size, the horizontal and vertical spacing is meters, and the upper plane of the ash cake is the elevation of the ground surface layer. If the room is larger, it is also necessary to wipe the bars. The mortar material mix ratio of plastering cake and standard reinforcement is the same as that of plastering mortar.

Ground leveling, cement mortar ground construction technology The construction of cement mortar ground is relatively simple, and its construction process is as follows: base treatment elastic line, according to the rules of cement mortar plastering surface maintenance. (A) the base treatment of the cement mortar surface layer is paved on the concrete cushion of the floor, and the key processes of the cement mortar surface layer are prevented from hollowing, cracks, sanding and other common quality problems during the treatment of the base layer.

Therefore, it is required that the base layer should have a rough, clean and moist surface, and all floating ash, oil stains and impurities must be carefully removed, otherwise a layer of isolation layer will be formed, which will make the surface layer not firmly combined. The surface of the base layer is relatively smooth, should be chiseled, and rinsed with water, the washed base, it is best not to go up. When the cement mortar ground surface layer is made on the cement mortar cushion and screed layer of cast-in-situ concrete, its compressive strength reaches that the surface layer can be laid, so as not to damage its internal structure.

2) Find the rules Find the rules is to determine the specific standards in the construction of cement mortar ground, mainly including the standard line of the horizontal base, do the standard reinforcement, find the slope and check the correct work. (1) Before plastering the ground of the reference line, a horizontal reference line should be popped up on the surrounding wall as the basis for determining the elevation of the cement mortar surface layer. The practice is based on the ground ( , popping up on the surrounding wall or as a horizontal baseline according to the actual situation.

The ground elevation is measured according to the horizontal baseline, and the horizontal auxiliary baseline is bounced on the wall as the horizontal datum of the ground surface layer epithelium. It is necessary to pay attention to the elastic line according to the thickness of the cement mortar surface layer required by the design. (2) Make standard reinforcement according to the horizontal auxiliary reference line, starting from the corner of the wall along the wall every fan ash process.

First of all, pop up the horizontal control line on the wall, clean the base layer (that is, the ground before you level), the base must be cleaned up, and the concrete surface of the original structure must be exposed, otherwise it is easy to lead to the hollowing of the leveling layer, and sprinkle water to moisten the base layer after cleaning, and then use cement mortar on the ground according to the control line to make the control point of the ash cake type, the thickness of the ash cake is the same as the thickness of the ground leveling layer you want to do, and then start to do the ground, pave the cement mortar in order from the inside to the outside, and the ratio of the mortar can be 1: 3 (the volume ratio of cement and sand), with the paving with the scraper to scrape flat according to the ash cake, with wait until the leveling layer has a certain strength, (finger press, there is a shallow mark), and then press both sides with a wooden rub. The next day sprinkle for curing.

When the thickness of the mortar exceeds 2 cm, some small stones must be mixed into the mortar to prevent it from cracking.

When renovating the house, be sure to carry it outCement floor leveling。If the ground is uneven and pitted, it will affect the subsequent installation of ground materials. Therefore, the process of repairing and leveling the ground with cement is called ground leveling.

Through the ground leveling will be the slope of the ground or the ground with small pits to fill the leveling, the following is a specific introduction to the cement floor leveling meaning.

1. What does cement floor leveling mean?

1. The ground leveling is to make the decorative materials of the upper layer play a better role. For example, if you want to install it on the ground, the wooden floor is framed first, and then the wooden floor is installed. If the ground is uneven, it will not meet the basic requirements for the installation of wooden floors.

Forced installation of wooden flooring will have the effect of empty and shaking, which will lead to increased wear and tear of the wooden floor, and will also cause damage to the wall coating.

2. If the ground is uneven, especially if there are many ups and downs, then the overall strength of the ground is not enough to make rock, and the stability of the materials installed on it will also be affected. In the end, the floor is easy to dust, and there is always dust in the room, no matter how much you clean it. Therefore, when doing ground decoration, the ground must be leveled first, otherwise there will be endless troubles.

3. First of all, the grassroots treatment, clean up with water, remember that there can be no water. Clean up the ash or the milk that sticks to it, and then clean it with a broom, and then pop up the control line of the cushion on the surrounding walls and columns according to the horizontal standard line and the designed thickness. If it is a room with a design slope, the line should be pulled according to the design slope requirements and the slope pier should be erased.

Then the concrete should be stirred with an appropriate amount of water, and then the substrate should be moistened, and a layer of plain cement slurry or interface binder should be laid on the bottom layer, which will be laid from the inside to the outside. According to the thickness requirements, pave the concrete, and finally the ground leveling, with the horizontal control line and leveling pier on the wall column as a mark, check the flatness, if it is high, shovel it off, if there is a recess to fill it. Scrape flat with a horizontal scraper, then rub the surface flat with a wooden trowel.

Second, the ground leveling ** detailed introduction.

1. For example, 325 cement has a ** ranging from 18 yuan to 21 yuan, generally speaking, 21 yuan is full catty, and 18 yuan is less than catty. There is also yellow sand, coarse sand is 4 yuan a bag, can not use fine sand, the salary is 10 yuan a square meter.

2. Ground leveling is composed of two parts: material cost and labor cost, whether the material is good or bad and artificial technology will affect the level of the project, and there are also 20-60 yuan per square meter. All in all, it is necessary to choose materials according to their own requirements, such as **, and cannot lead to leveling or decoration for the sake of comparison and other factors.

3. According to the manual, the leveling of cement mortar is about 25, the leveling of gypsum is 6-8 yuan, and there are more than 10 yuan. **Just a reference value, each building materials market has a different **, and it depends on the quality of leveling, regional and other factors can determine whether the ground leveling ** is more or less.

After reading today's article, we learned the meaning of ground leveling. Before decorating the house, it is necessary to carry out ground leveling, which is also the most basic work of decoration. The ** of ground leveling is also unequal, and it is generally calculated according to square meters.

<> "How to repair uneven cement floors.

1. First of all, clean the dust on the cement floor thoroughly, and clean it in place as much as possible.

2. Then carry out leveling treatment, and mix the cement and mortar, scrape or roll on the uneven ground.

3. Repeat the construction twice, and the construction will be carried out once every 2 hours, until the batch scraping or rolling coating to the cement is completely flattened and stopped.

4. Finally, it is to repair the brush treatment, and the small gaps or deviations can be filled.

What are the requirements for cement floor construction.

1. Material mix ratio.

The ratio of the surface layer of cement mortar shall not be less than 1:2, its consistency shall not exceed cm, and the cement mortar shall be mixed evenly and the color shall be the same.

2. Key points of construction.

1) Before paving the surface layer, the base layer is wetted, and on the second day, a layer of cement slurry with a water-cement ratio is brushed, and then the surface layer is paved. If the cement slurry bonding layer is painted too early, it will not achieve the effect of bonding with the base layer and the surface layer, but will lead to the hollowing of the ground. Therefore, it must be wiped as you go.

2) When the cement mortar appears to be initially set, you can start to press the second time with a steel trowel, and it should be compacted, not leakage, the second calendering is particularly important, and the surface layer should be cleaned up bubbles and pores to be smooth.

3) Wait for the cement mortar to solidify, and then use an iron trowel to press it a third time. Apply a little force during the application process and flatten, compact and calender the trowel lines and pores left behind by the second pass.

4) The cement floor calendering must survive three times, and the duration of each plastering should be controlled properly to ensure the quality of the project. Calendering too early or too late to inspect the foundation can lead to sand and ash quality problems.

If the concrete floor is uneven, there are several remedies that can be considered:

Use floor leveling materials: Floor leveling materials can be plaster, cement, plaster, etc., which can be poured on the ground and then spread evenly on the ground using a tool and wait for it to dry.

Laying mats or carpets: Laying mats or carpets on concrete floors can effectively reduce the unevenness of the ground and can increase comfort and aesthetics.

Grinding the ground: If the unevenness of the cement floor is more serious, you can use a grinder to polish it smooth to achieve a smooth effect.

Re-flooring: If the unevenness of the cement floor does not seriously affect the effect of home decoration, you can consider re-laying the floor, such as solid wood flooring, laminate flooring, etc.

In conclusion, there are a variety of remedial measures that can be taken for the problem of uneven cement floors. When choosing remedial measures, it is necessary to choose according to the actual situation and needs, and ensure the quality of the repair.
