How to do cement self leveling ground? Cement self leveling ground do

Self-leveling is a type of cement and is often used as a construction process.

As a type of cement: self-leveling cement is often used for the base leveling of floors and carpets, and is also an important part of epoxy flooring. Generally, the thickness of a single layer construction does not exceed 5mm, and the cost is about 40 70.

As a construction process: cement self-leveling and epoxy resin self-leveling are common. Cement self-leveling usually cannot be directly used as the ground, can only be used as a base layer, ranging from tens of yuan to more than 100 yuan per square meter.

The self-leveling process of epoxy resin is complex and needs to be entrusted to professional construction personnel, which can be used in a large area to form a seamless floor. The cost of epoxy self-leveling is high, generally more than 200, rich in color, high in durability, and environmental protection is greatly affected by materials and construction.

Self-leveling is cement, so it will definitely crack, no matter how expensive your materials are, no matter how good the construction techniques of the master you find, this is unavoidable. Because I can't see the top floor, I'm okay with that.

1. Self-leveling is actually a way of ground leveling, so at this time you have to pay attention to **, I compared the three, and finally let my flooring company help me contact the master to do, contract labor and materials;

2. Because I need to self-leveling the total height of the floor in the later stage, self-leveling can only do 3 millimeters, which must be done before! Certain! You have to tell the master that it's okay, otherwise it's going to be troublesome (knock on the point!)

3. Before self-leveling, be sure to explain to your construction team in advance to clean the ground, clean the ground very clean, small particles, hair, etc. are not allowed, otherwise cement bumps or cracks are easy to appear behind;

4. I read the tutorial, self-leveling should be used to eliminate bubbles when doing it, if the bubbles are not eliminated, there will be white spots on the ground after drying, there are many white spots on the ground in my house now, but the price is worth the goods, because I am going to lay the floor directly on it in the later stage, so there is no requirement too harsh If you are directly self-leveling the ground, you still have to make it clear to the master;

5. Self-leveling drying method can only be dried in the shade, after the project is completed, you should tell the project manager not to arrange people to construct for at least two days, otherwise you will be embarrassed when the workers go down!

Live well for the user Birds who can't wake up: due to the installation of fresh air and floor heating, as well as the leveling without leaving expansion joints, the ground expands and cracks after heating, and the unevenness is serious, so it has to be self-leveling. One can be leveled and the other is to prevent the return to the sand, now I feel at ease!

The first is the base treatment: the strength of the base concrete before construction must be C20, and the uneven places, cracks and holes should be treated and leveled in advance, and then the scattered debris on the base surface must be removed, and the surface must be kept hard and neat. Water the base concrete surface layer and make sure that there is no water attached to the front layer of pouring.

The new concrete base of ordinary cement shall be self-leveling construction after 21 days of construction, and the new concrete base of sulfoaluminate cement construction shall be self-leveling construction 7 days after completion.

Water: Cement: Fine Sand 1:

The ratio of 1:1:1 is stirred well, and it can be brushed or sprayed on the base surface.

The reference dosage of EC-1 is: When the surface is not sticky, self-leveling construction can be carried out.

Mixing: When a small area or highway is constructed, a small electric mixer (200 500 rpm) can be used to stir in a barrel, and a complete package is required for each stirring; When building a large area, it can be mixed with a high-speed mixer and pumped with mortar. Pour an appropriate amount of water into the bucket, turn on the blender and slowly add a pack (it is best to add it within 1 minute), stir for 4 to 5 minutes, stand still for about 1 minute, and stir again until it is a uniform and lumpy slurry.

In case of cold, it is advisable to stir with warm water (no more than 40 °). The temperature of the mortar is kept above 5.

Pouring and leveling: pour out the stirred one, spread it evenly, and control the thickness with a special tooth scraper, the construction thickness of this product is 3mm, and the thickness of a construction is 3 30 mm, and the reference amount is used. The construction personnel can wear spikes to enter the construction ground, and scrape the mortar surface layer with a tooth scraper to eliminate the unevenness of the dumping joint and maintain the required thickness.

Roll gently with a deflated roller to eliminate air bubbles created when stirring. The mixture should be used within 35 minutes.

Curing: It can not be cured under normal temperature conditions, and it must be maintained for 1 3 days after watering or covering wet sacks and straw mats after initial hardening. Heavy traffic ground needs to be maintained for 3 days before it can be passed.

Cement self-leveling ground is the use of cement (high alumina cement, Portland cement, etc.) after adding water, so that it forms a free-flowing ground coating, according to the situation of the potholes on the ground can quickly construct hardened ground materials on the ground (only suitable for relatively horizontal ground, inclined ground is not suitable, in the case of low fluidity can be quickly constructed on the ground with a low degree of inclination, so it does not require the premise of absolute level). Cement self-leveling is a high-tech green product with high technology content and complex technical links. Cement self-leveling has a wide range of uses, which can be used in industrial plants, workshops, warehousing, commercial stores, exhibition halls, gymnasiums, hospitals, various open spaces, offices, etc., and is also used in homes, villas, warm small spaces, etc.

It can be used as a finishing surface layer or as a wear-resistant base layer.

Decoration knowledge, self-leveling ground practice to share with you, learn to become a decoration master in seconds.

How exactly does cement self-leveling ground work, you may not believe it.

Self-leveling flooring is done in the following way:

1. Before the construction of cement self-leveling ground, the doorway, drainage outlet and other parts that may leak should be blocked.

2. The base treatment includes two aspects, one is that there can be no debris in the construction area, and the other is smooth and free of debris.

3. After the base treatment is completed, the doors and windows should be closed, the interface agent should be painted, generally painted twice, and then the second time after the first time is dried, and the painting process should not be omitted, and it should be as uniform as possible.

4. After the interface agent is dried, the cement self-leveling powder is stirred with water, and the cement self-leveling powder is stirred into a slurry with water, and then the pouring can begin.

5. With the help of auxiliary tools such as scrapers, it is also necessary to use an exhaust drum to roll on the self-leveling surface of cement to play the role of exhaust and avoid the generation of small pores.

6. After the pouring is completed, the cement self-leveling needs to be cured for a certain period to keep the air not circulating.

Cement self-leveling is a high-tech green product with high technology content and complex technical links. It is a dry-mix powder material composed of a variety of active ingredients, which has a wide range of uses, and can be used in industrial plants, workshops, warehouses, commercial stores, exhibition halls, gymnasiums, hospitals, various open spaces, offices, etc., and is also used in homes, villas, warm small spaces, etc., and can be used as a finishing surface layer or as a wear-resistant base.

Its safety, pollution-free, beautiful, rapid construction and putting into use are the characteristics of self-leveling cement. It elevates the civilized process of construction, creates a high-quality, comfortable and flat space, and adds a brilliant color to life with a variety of Peugeot finishes. Self-leveling cement has a wide range of uses, and can be used in industrial plants, workshops, warehouses, shopping malls, exhibition halls, gymnasiums, hospitals, various open spaces, offices, etc., and is also used in homes, villas, warm small spaces, etc.

Self-leveling is generally divided into cushion self-leveling and surface self-leveling. Cushion self-leveling is a mountain limb used under materials such as wooden flooring, plastic flooring, carpet, etc., and the surface layer of self-leveling can be used directly on the ground. The quality of the two varies greatly.

Common species

Ordinary cushion self-leveling: suitable for ground leveling before laying PVC flooring, plastic flooring, wood flooring, carpet and other materials. Because the self-leveling strength and crack resistance of the cushion are ordinary, it cannot be used directly on the ground, but only used under other ground materials.

Cushion self-leveling is mostly used in hospitals, kindergartens and other occasions.

High-strength surface self-leveling: suitable for industrial ground, high strength, good wear resistance, can be used directly on the ground, mainly used in new or old comic project renovation projects, as well as industrial ground fine leveling. The surface layer is self-leveling and delicate, cement gray, with a simple and natural decorative effect.

Thin for paving light industrial floors, where the ground can carry pedestrians; Make thick floors that can carry heavy industries such as forklifts, or use them in underground garages.

Self-leveling of color surface layer: In addition to the above-mentioned characteristics of high-strength surface self-leveling, colorful color elements are added to meet people's requirements for more colors of surface self-leveling. The color surface layer is self-leveling, and there will be a slight color difference in color shade, and it is not possible to achieve the overall uniform color consistency.

In the construction of the ground, in order to achieve a certain flatness, most users will use the self-leveling process, although this construction method is very common, but the technical requirements for workers are superb, so ordinary people may simply achieve the desired effect, so how to self-leveling the cement floor? Let's take a look at it below, I believe it will bring you different insights.

1. Before construction, the doorway and drainage outlets and other areas that may leak should be closed. 2. Treat the base layer, and there shall be no debris in the construction area, and it should be kept flat. 3. Close the doors and windows, apply the interface agent, and do not omit it during the operation to keep it even.

4. After the interface agent is dried, the cement self-leveling material can be stirred with water and then poured.

Precautions for cement self-leveling construction.

1. For this construction process, the temperature of the ground shall not be lower than 10 degrees Celsius, the humidity shall be kept below 90%, and there shall be no strong wind through the hall, otherwise it is easy to appear local premature drying.

2. For this process, it will have relatively high requirements for the base layer of the ground, for example, there shall be no loose concrete, sundries or grease. It is also necessary to pay attention to the fact that the interface agent should be kept dry so that it can be more cohesive, and it is also necessary to pay attention to maintaining ventilation during construction.

3. The best water quality used in the construction is clean tap water, so as not to affect the overall texture, and at the same time, for this process, it must be continuously constructed, and there is no stop in the middle. After adding water, the use time is 20-30min, if it exceeds this time, the mortar will lose its fluidity due to solidification, which will affect the smooth progress of construction.

Summary: The above about how to do self-leveling cement floor, what are the precautions for cement self-leveling construction are introduced here, I hope to provide you with some help. If you want to know more about decoration, you can pay attention to the relevant information of Qeeka Home.

The construction method of self-leveling is as follows

1. Before the construction of cement self-leveling, it is necessary to pay attention to the proportion of cement self-leveling, and the appropriate proportional effect strength is good, and the ground without strength is often the root of the ground ash in the later stage, and the starting position of the greasy self-leveling is also very important, and it is necessary to pay attention to ensure the flatness of the entire ground.

2. A dry mortar material made of special cement fine aggregate and a variety of imported polymer additives is mixed in strict proportion, and formed a paddle body that can be leveled by itself after being mixed with water, without harmful gases and harmful substances, and has been widely used in factories, hospitals, garages and other places.

3. Base surface treatment to remove oil stains and loose matter, with potholes or grooves with mortar or special putty to scrape and level first, cover the finch super high or protruding point should be knocked out or smoothed, in order to save materials and improve the quality of construction.

4. It can not be maintained under the condition of normal temperature in the morning, and in the case of high land temperature or low temperature, it must be maintained for 1 to 3 days after the initial hardening, and the heavy traffic ground needs to be maintained for 3 days before it can be passed.

The construction steps of self-leveling cement floor are as follows:

1. Base treatment: The strength of the base concrete before construction must be C20, and the uneven places, cracks and holes should be treated and leveled in advance, and then the scattered debris on the base surface must be cleaned up, and the surface must be kept hard and neat. Water the base concrete surface layer and make sure that there is no water attached to the front layer of pouring.

Water: Cement: Fine Sand 1:

The ratio of 1:1:1 is stirred well, and it can be brushed or sprayed on the base surface.

The reference dosage of EC-1 is: When the surface is not sticky, self-leveling construction can be carried out.

Introduction of self-leveling cement floors

Cement self-leveling ground, the main material is cement, poured directly on the ground, but also added other materials, mixed with water, forming a liquid substance. After falling on the ground, because the ground is uneven, it will flow along the trend, so that the ground is automatically leveled.

The effect of this kind of cement self-leveling ground is self-evident, because it can achieve the whole without gaps, and it is automatically leveled, and the final result is very smooth and flat.

In some factories or shopping malls, the main advantage of using cement self-leveling is that the construction is more convenient and can save the cost of construction. In addition, after the construction is completed, it can be dustproof and waterproof, and it is more convenient to clean up later, so it is especially suitable for factories and workshops.
