How to get self leveling, how to self leveling?

The technical application of self-leveling is first of all an innovation, the floor material in the liquid state automatically flows after spreading to the ground, of course, this flow is not arbitrary, the liquid automatically finds the low-lying area on the ground and fills it, and finally the whole ground flows into a mirror-like flat after stationary, condensation and solidification. The whole process does not rely on manual plastering, and this flowing process is the best proof of a true self-leveling floor material.

First, the requirements of the foundation ground:

The foundation cement floor is required to be clean, dry and flat. The details are as follows:

There should be no empty shell between the cement mortar and the ground.

There can be no sand particles on the cement mortar surface, and the mortar surface should be kept clean.

The cement surface must be smooth, and the height difference within two meters is required to be less than 4mm

The ground must be dry, and the moisture content should not exceed 17 degrees measured with a special test instrument.

The strength of the base cement shall not be less than 10MPa.

2. Preparation before construction:

Before the construction of star gecko self-leveling cement, the foundation ground must be polished with a grinding machine to grind off impurities, floating dust and sand particles on the ground. Flatten the level of the local raised area. After sanding, sweep off the dust and vacuum it clean.

After cleaning the ground, the surface treatment agent must be treated before the self-leveling cement, the treatment agent must be diluted according to the requirements of the manufacturer, and the ground treatment agent must be evenly coated on the ground with a non-dehairing wool roller in the direction of first horizontal and then vertical. Make sure to apply evenly and leave no gaps. After applying the treatment agent, according to the different properties of the product, wait for a certain period of time to carry out the construction of the self-leveling cement above.

Cement surface treatment agent can increase the adhesion between self-leveling cement and the ground, and prevent shelling and cracking of self-leveling cement.

It is recommended to apply the floor treatment twice.

Third, the construction environment.

Slight ventilation is allowed in the work area, but windows and doors should be closed to avoid drafts during and after construction. The indoor and ground temperature should be higher than 10 during construction and within a week after construction. The relative humidity of the ground concrete should be less than 95%.

Fourth, self-leveling construction:

Prepare a measuring bucket, add water in strict accordance with the water-cement ratio of the self-leveling manufacturer, and use an electric mixer to stir the self-leveling thoroughly. Stir in two parts, usually about 2-3 minutes at the first time, with a 2-minute pause in between to allow it to dissolve well, and then stir for about 3 minutes.

Stir thoroughly, and no lumps or dry powders appear. The stirred self-leveling cement must be in the form of a fluid.

The stirred self-leveling should be used within half an hour as much as possible. Pour the self-leveling cement on the ground, use a toothed target to open the self-leveling target, and target different sizes of areas according to the required thickness. After it is naturally leveled, it is rolled vertically and horizontally with toothed rollers to release the gas in it and prevent foaming.

Special attention should be paid to the smoothing of the self-leveling cement lap.

According to the different temperatures, humidity and ventilation conditions, the self-leveling cement needs 8-24 hours to be completely dry, and the next step of construction cannot be carried out before drying.

Self-leveling construction technology and precautions.

The construction method of self-leveling is as follows:

First of all, the ground should be treated and cleaned at the most basic level, and dust-free treatment should be done.

Then the drip test is carried out, and the water droplet area is clear without shrinking.

The purpose of pouring and brushing the interface agent is to close the base layer and enhance the adhesion strength of the ground base layer and the self-leveling mortar layer.

Pour self-leveling cement into the barrel, then add water, and when adding water (strictly follow the ratio of self-leveling and water on the manual), stir for no less than 2 minutes, and fully integrate.

Dump the self-leveling cement on the ground, so that the cement can flow along the ground, but can not completely level every corner, the construction personnel need to gradually push the cement away, use special tools to level each corner, and then use the defoaming roller to press the self-leveling, eliminate the blistering part and assist in eliminating the seams on the self-leveling ground.

According to the temperature and ventilation of the site, when the self-leveling is completely dry, you can prepare to lay the floor.

Self-leveling is the use of materials with automatic leveling or slightly auxiliary leveling function, paving the surface layer after on-site mixing, common self-leveling ground includes mud-based self-leveling ground, resin self-leveling ground and resin cement composite mortar self-leveling ground, etc. After diluting the special self-leveling cement and adding other additives, it can flow to the ground according to the unevenness of the ground, and the ground can be automatically leveled.

Introduction of self-leveling.

The self-leveling floor engineering surface coating mold is beautiful, high clean, high wear resistance and load, and the most important thing is the beautiful decorative effect, because the first reaction of people's vision is the color of the surface and the effect of the surface.

The quality defects of the surface coating of the artesian lifting hidden flat floor engineering are: shrinkage holes, spots, patterns, color difference, floating color, discoloration, exposed bottom, biting the bottom, whitish, brushed, matte, falling off, sticky, oily, orange peel and other quality problems.

Self-leveling requires a high degree of cleanliness, beauty, dust-free, sterile and anti-static electronics, microelectronics industry, GMP standard pharmaceutical industry, blood products industry, can also be used in schools, offices, shopping malls, homes and other floors.

In home decoration, I often see people leveling the cement floor, and I can't help but think, the cement floor is paved into the house, isn't this what our hometown does, and now the big city is also popular? If you take a closer look, it turns out that it is very different, this kind of ground is called self-leveling. This natural texture and natural color have become very popular in recent years.

Next, I will introduce to you what is self-leveling? Let's find out!

Self-leveling, in fact, is a leveling process, using the flowable field trembling beam dynamics of self-leveling mortar, spread on the ground, free flow to form a flat surface. The formed surface layer can be used as a cushion for wooden flooring, which solves the problem of high requirements for floor flatness of thin floors. In addition to being used as a cushion for the floor, cement self-leveling can also be used as a direct substitute for the floor.

Steps of self-leveling construction.

1. First of all, the base surface should be treated, the construction surface is required to be clean and dust-free, there can be no small stones or other granular items, if there are large cracks on the construction surface, it needs to be treated and then dumped self-leveling mortar;

2. Then evenly apply the interface agent, which can make the self-leveling and the base surface better bonded;

3. After the base surface is treated, you can start construction, you must add water and stir in accordance with the instructions for the use of self-leveling mortar, otherwise the ground may crack, shell, and the effect is very poor.

4. During the construction process, the cave foundation must pay attention to defoaming, if it is not done, there will be many white spots on the self-leveling surface, and the construction master will use a special roller + spikes to defoam.

5. After the construction is completed, the self-leveling has not yet dried, and it must not be ventilated, but must be dried in the shade, otherwise the wind will become "layers of ripples".

My conclusion: The above is about what is self-leveling? I hope it can help you. I believe that after the introduction of the content, you will have a better understanding of the steps of self-leveling construction, and if you have any needs in the future, you can also refer to it.

In the past, self-leveling was a leveling process for the ground, and by using the characteristics of self-leveling mortar with good fluidity, it could be evenly spread on the ground to obtain a ground with high flatness.

Cement self-leveling automatically levels the ground according to the uneven nature of the ground, and after curing, it can form a smooth, flat and seamless new panel.

Originally, the process of cement self-leveling was only used in ground leveling, and its role was only as a cushion for wooden floors, because of its high flatness, it can well solve the requirements of wooden floors for ground flatness, and can greatly reduce cracking, hollowing, deformation and other problems.

Later, it was found that cement self-leveling mortar can produce natural and random patterns and textures when flowing, and the decorative effect after curing is not bad, which can replace wooden floors and tiles, and cement self-leveling ground has gradually become popular.

Hey, Jee Pei pro, let me briefly introduce the construction method of self-leveling: 1Clean the floor:

First of all, the ground should be cleaned and dust, oil and other debris should be removed, so as not to affect the construction effect. 2.Dealing with ground crevices:

If there are gaps in the ground, they need to be filled with caulk to keep the ground level. 3.Apply the primer:

The floor is coated with a macro permeability paint to enhance the adhesion and abrasion resistance of the ground. 4.Stirring self-leveling material:

Pour the self-leveling material into clean water and stir well according to the ratio on the instructions. 5.Pour the self-leveling material:

Pour the stirred self-leveling material onto the ground and spread it evenly with a spatula or scraper. 6.Leveling the ground:

Use the self-leveling tool to spread the self-leveling material on the ground evenly so that it forms a flat surface. 7.Wait for drying:

Wait for the self-leveling material to dry, the time is generally about 24 hours. Self-leveling is a method of ground leveling, which is suitable for all kinds of ground, such as cement floor, wooden floor, floor tile, etc.
