Available through 5 8''The threaded fitting is connected to the tripod.

The setting time, strength development and moisture content of the ground cement leveling material are determined. It is recommended to spend more than a week on the regular decoration of the leveling floor, so that the screed layer can be fully maintained, and the moisture in the volatile pores with better growth strength can make the ground dry, smooth, clean and sand-free before paving.

1. The ground should be leveled with mortar, and the elevation should be equal, if a house is all used, it is relatively better, the living room floor tiles, and the bedroom floor should be accurately determined according to the thickness of the floor and the elevation of the living room floor tiles, otherwise there are steps at the joint. The following auxiliary materials must be paved flat.

The place of the interface must be done well, and if it is silica gel bonding, it must be cleaned after it is dry.

2. The floor can not be too tight or too loose, the laminate floor needs to be leveled first, and the laminate flooring business will generally lay a layer of moisture-proof, and the keel is played below the solid wood floor, and the flatness requirements for the floor will be relatively low.

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.

Real shooting to do cement mortar ground leveling.

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.

Co-creation fast leveling system is a new type of ground leveling material, which has multiple effects such as lightweight sound insulation and heat insulation, in order to fully replace the traditional cement mortar leveling, and its cost performance is higher!

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.
