How to do self leveling cement curing floors

Preparation before construction:

Before the construction of self-leveling cement, the foundation ground must be polished with a grinder 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 coating the treatment agent, according to the different product properties of different manufacturers, wait for a certain 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.

Self-leveling construction:

Prepare a bucket large enough, add water in strict accordance with the water-cement ratio of the self-leveling manufacturer, and use an electric mixer to mix the self-leveling thoroughly. Stirring is done in two parts, usually the first stirring is about 5-7 minutes, and the middle needs to be paused for 2 minutes to allow the reaction to occur, 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.

The specific steps are as follows.

1. Ground cleaning: Use a broom to clean the ground.

2. Spray concrete sealing curing agent: Splash a sufficient amount of concrete sealing curing agent on the ground, and drag it back and forth with a mop to fully absorb the ground to saturation. Increase the hardness and strength of the cement floor to ensure that the later repair materials will not fall off due to the excessive looseness of the ground concrete.

3. Ground water: Splash enough water on the ground to absorb the ground until it is saturated. After the ground absorbs water, it is conducive to the bonding and maintenance of the later repair mortar.

4. Spray floor repair agent: spray an appropriate amount of floor repair agent on the ground. Increase the adhesion of the repair mortar to the ground.

5. Scrape the repair mortar in batches: scrape the prepared repair mortar to the ground in batches in order to fill the potholes and depressions on the ground and improve the smoothness of the ground. It is conducive to mechanical grinding in the later stage. (Too uneven ground is not conducive to mechanical grinding).

6. Ground grinding: Grind the ground deeply many times with a heavy-duty floor grinder. (diamond grinding disc 30 grinding separately) remove the surface excess repair mortar, obtain better ground smoothness, facilitate later grinding.

7. Ground repair: fill the ground potholes with repair mortar again After deep grinding, there will be some potholes on the ground, which need to be repaired again.

8. Ground grinding: use a heavy-duty floor grinder to deeply grind the ground many times. (Diamond grinding disc 80 times grinding) to remove the ground scratches and excess repair mortar during the previous "ground smoothing".

Mix the main agent and curing agent in proportion, stir it well, and roll it with a roller during the use time, so that it should be thin and uniform when rolling, and it should be glossy after coating, and the glossy place should be recoated in a timely manner. The next process can be carried out after 12 hours.

For the surface of the substrate that has been dried, the area of about 10C is moistened with local water, and then a pH test paper with a measurement range of 5-14 is pasted on the surface of the moistened substrate to make it wet, and the pH value is compared with the pH value sample within 5s to read the pH value. The pH value of the floor surface should be if the alkalinity is too large, use a zinc sulfate or zinc chloride solution with a concentration of 15%-20%, scrub the surface of the matrix, and finally rinse it with clean water and dry it.

Precautions for cement self-leveling construction.

It is first recommended to check the moisture, flatness and hardness of the ground to confirm that it is dry, flat and free of cracks. Then the ground is thoroughly cleaned of all kinds of dirt, the ground is fully polished to absorb the dust, and then the interface agent is coated with a foam roller.

It should be noted that after the coating of the interface agent is completed, it needs to be well ventilated so that it can be completely dry, and self-leveling construction can be carried out after drying. Self-leveling cement needs to be stirred with a slurry electric drill, stirring until the flow state is uniform, and the cement must be free of agglomeration. The mixture is then quickly poured evenly into the area to be constructed, and then the artesian evenly cloth is spread with a rake, which can be rolled and pulled with a roller to release the air.

1.Basic treatment: repair, polishing, dust removal according to the condition of the ground, after treatment, the surface of the floor is smooth, dense and dry, no oil stains, and no loose and fragile particles, before the next process of construction.

2.Self-leveling primer: Roller coating with strong epoxy primer with sealing and adhesion to enhance surface adhesion;

3.Self-leveling mortar medium coating: add an appropriate amount of epoxy resin to quartz sand, evenly coat it with a trowel, whether the construction handover treatment is appropriate, the position of the baseboard is straight, and the wall is not separated, and it is smooth.

4.Epoxy putty: use epoxy putty to construct two lanes, so that the ground is completely flat without holes, and there is no batch of knife marks and sanding marks before the top coating construction can be carried out.

5.Epoxy artesian plane paint: apply a uniform trowel with artesian plane paint, and the overall ground will be bright and clean after completion, with uniform color and no hollow drums, and pay attention to the treatment of the construction junction; The coating is required to be uniform, no sagging, no pinholes, smooth and smooth.

Precautions for the construction of epoxy self-leveling flooring:

1. The construction temperature is 5 35, please consult the factory if the temperature is too high or too low, and the humidity range of the construction environment is 30 80%.

2. The mixing ratio of the pigment and the curing agent component of the self-leveling coating is 5:1, and it is fully stirred before use.

3. Each process must wait for the previous coating to reach the degree of solidity before it can be carried out, and the construction cannot be carried out in a hurry.

4. For the process of different thicknesses, the amount of material used for the middle layer sand scraping can be appropriately adjusted according to the actual situation.

Self-leveling floor paint is a new type of floor paint, which has the advantages of environmental protection, wear resistance, corrosion resistance, etc., because it can meet the requirements of many places, so it is widely used by self-leveling floor paint manufacturers. But in ordinary use, if the use is improper, it is possible to cause damage, once found, it is necessary to repair the self-leveling floor paint manufacturer in time, so as not to increase the damage area, this article self-leveling floor paint manufacturers share with you is its repair method: 1, spraying repair method advantages:

Spraying repair has the advantages that other methods cannot match, the traces after repair are smaller, the aesthetics are good, and the material is saved. 2. Point repair method self-leveling floor paint manufacturers point repair method is a method that is super commonly used at this stage, and most construction personnel repair damaged self-leveling floor paint are used by this method. Pros:

The construction process is simple and easy to master, and the amount of raw materials used is small. 3. Advantages of the overall covering method: beautiful and beautiful.

Self-leveling floor paint manufacturers 4, FRP construction method, etc. Scope of application: long cracks such as expansion joints in building structures. 1. Grassroots treatment:

Now cut the V-shaped opening at the crack and use a vacuum cleaner to suck off the floating ash. 2, primer construction 3, repair construction 4, self-leveling putty construction above is several repair methods of self-leveling floor paint, it is not difficult for us to find that the characteristics of each method are different, so the applicable occasions are also different, we should choose the repair method, according to the actual situation, choose the appropriate method, so as to achieve better results. Friction on the self-leveling floor is mainly caused by people and vehicles.

When employees enter the clean area of the self-leveling floor, they should change to soft-soled shoes to reduce the loss of personnel friction. Forklifts and trailers for transportation are used in self-leveling floor areas, and care needs to be taken to maintain a smooth speed as much as possible and avoid braking. When the goods are unloaded and stacked, avoid scratches on the side and sharp corners of the goods on the self-leveling floor.

The wheels of the cart and pallet truck should be made of hard or elastic rubber wheels.

The patching method is later.

Epoxy self-leveling floor paint has its characteristics: high degree of cleanliness, stain resistance, sterility and other characteristics.

1. It is prepared with solvent-free high-quality epoxy resin and curing agent.

2. The surface is smooth, beautiful and has a mirror effect.

3. Resistant to strong acid, alkali, salt and oil medium corrosion, excellent resistance to strong alkalinity.

4. Wear-resistant, pressure-resistant, impact-resistant, and high degree of cleanliness.

1. Ground treatment: polishing, repairing, decontamination and dust removal should be done according to the ground conditions.

2. Epoxy primer: Epoxy primer with strong permeability and adhesion is used to enhance surface adhesion.

3. Epoxy mortar layer: add epoxy two-component to quartz sand and evenly coat it with a trowel to enhance the impact resistance of the ground.

4. Epoxy putty layer: add an appropriate amount of putty powder with epoxy two-component and evenly coat it with a trowel.

5. Self-flowing plane paint: evenly coated with self-leveling epoxy topcoat.

Self-leveling floor paint construction process:

1. Base cleaning: It is to remove the loose mortar, glue, slurry, and dust on the structural plate, and chisel the concrete slurry at the corner of the wall and the ground.

2. Make ash cakes: The spacing of ash cakes is required to be within meters, so that the scraper can be hung up. Before making ash cakes need to be watered and moistened, otherwise the ash cakes will fall off. After doing a good job, water and cure it twice (to prevent sanding). The flatness of the ash cake is required to be within 4mm.

3. The base layer is soaked in water for 1 day to soak the concrete surface layer. Sweep while flushing when draining the water to sweep away the dust. Prevent dust from accumulating in floor drains or wall corners to form an isolation layer, resulting in floor hollowing.

4. Sweep the slurry: Before pouring the concrete in the morning, sweep the slurry first. The cement slurry can not be thick, there can be no stagnant water, and the area can not be swept more, and the position to be poured within the specified time is required.

5. Scraping: In the process of scraping flat after the concrete is paved on the ground, the commercial concrete will come out with floating slurry, which is not a good thing, it is fly ash that has no strength, and must be scraped out from the inside out. Some people do not scrape off just scrape the concrete flat and then sprinkle some dry cement mixed as the surface layer of the floor, which does not know that this is the reason for low efficiency, surface layer shelling, peeling and cracking, there is no sand in the slurry is powder, and the thickness of 3mm will crack and shell.

6. Grinding the upper disc: After the concrete is scraped flat, it is necessary to wait for a period of time, and when the feet of the upper person do not sink, the grinder disc is polished again, and the wall is manually smoothed 30cm.

7. Secondary scraping (double ruler) This is the key to ensuring the flatness of the floor. When the disc is grinded, the dry place is flat, and the rotten place will grind a pit, so it is necessary to repeat the ruler.

8. Sprinkle the cement dry, and when the cement absorbs the water, go to the disc twice, and use the grinding slurry as the surface layer of the floor. The effect of dry cement is that it does not have sand.

9. The blade of the grinding machine can be calendered twice while the fire is waiting.

10. Maintenance: Half a day to do the water barrier of the threshold mortar, and then half a day to release water for maintenance.

Epoxy self-leveling floor paint is different from other series of epoxy resin floor coatings, parking lot floor paint, etc., the construction requirements of this material are relatively high, if consumers find merchants to buy floor paint directly, they also need to find another construction team to lay, which if there is an epoxy floor quality problem, it is difficult to judge whether it is a problem of epoxy floor coating business, or the problem of the construction team. Foshan Lilan floor paint manufacturers.

It is precisely because the construction requirements of self-leveling floor paint are relatively high, so most floor paint manufacturers will formulate the construction process of epoxy self-leveling floor paint for customers, and how to formulate the construction plan of self-leveling floor has become the key to epoxy flooring. How to correctly formulate the construction process of epoxy self-leveling floor paint?

Regardless of which floor paint construction plan, the treatment of the base surface is crucial, use a dust-free grinder, shovel to clear the ground before construction, keep the ground clean, if it is a damaged floor, it needs to be repaired before the above work. Then it is to fully mix and stir with primer according to the ratio, evenly coat the cleaned ground, and coat the closed ground surface to make the primer penetrate the base layer and reach a certain required thickness.

In the epoxy self-leveling floor paint construction process, the construction of the first and second layers will be specially remarked, which needs to wait until 8 hours later, and if it is a flat knife evenly coated and scraped, it will also need to wait until 16 hours later. The last is the construction of the top coat, where the putty layer needs to be flattened first, the top coating material is fully mixed and stirred according to the ratio, and then evenly coated with a trowel.

If you want to develop a perfect epoxy self-leveling floor paint construction process, you must first understand the situation of the construction site, the quality of the ground, the requirements of customers, and the use of the construction floor, etc., the so-called knowing yourself and knowing the other side can win all battles, and the correct development of the construction plan is the same.
