The floor can only be laid after the cement is dry, generally about two weeks, depending on the site conditions.
Self-leveling construction specifications.
First, grassroots treatment.
Basic requirements: The surface base before self-leveling cement should be smooth, dry, firm, free of dust and oil, etc.
Construction steps and key points:
First, use a shovel blade to remove the original gypsum, paint, cement hard blocks and other protrusions on the ground, and use high-grade cement mixed with 107 glue to pad the potholes and cracks on the surface to achieve the requirements of ground leveling; Then use a grinder to polish the entire ground again to ensure that the ground is free of protrusions and loose surfaces; Then the leveled ground is naturally air-dried or quickly air-dried by heating, so that the moisture content of the whole ground does not exceed 6; Then use a broom to sweep the ground and all corners; Use a level measuring instrument to circle the particularly high place on the surface with chalk, and then use a grinder to carry out fine grinding in this local high place, so that the difference between the thickness of the place and the ground next to it does not exceed millimeters; Finally, use a vacuum cleaner to completely suck the construction ground several times, and be sure to remove the tiny particles on the ground.
2. Upper interface agent (base oil).
The purpose of the primer is to separate the surface base from the self-leveling cement and to have a certain degree of moisture-proof function. According to the requirements of different manufacturers, some water can be added to the base oil, and the proportion of water can be added according to the manufacturer's suggestions. After adding water, be sure to carry out sufficient stirring, and then use a roller that does not shed hair to evenly coat the primer on the surface according to the amount of use provided by the manufacturer, and the particularly dry ground can be divided into two times to paint the primer, the amount of use is the same as a brush, and the interval is determined according to the change of the primer.
3. Stir. The preparation work before mixing must be done sufficiently, and a group of construction workers had better keep multiple buckets, one for mixing, one for measuring water, and one for holding water. The bucket for measuring water must be accurate, and it must be strictly in accordance with the water ratio recommendations provided by the manufacturer.
The agitator must choose a high-power agitator, and the speed can be adjusted, at first put on the low speed gear, because the first stirring requires a large centrifugal force, after the cement is completely integrated into the water, it can be placed on the medium speed gear, and then stir for 2-3 minutes. After mixing 4-6 barrels, the mixing head should be cleaned to prevent self-leveling on the barrel wall and the mixing head from condensing into lumps after a long time. The choice of the diameter of the mixing head is based on the size of the inner diameter of the barrel, in general, the inner diameter of the barrel is the multiple of the diameter of the mixing head.
4. Leveling and defoaming.
Self-leveling work must be carried out continuously, and any cross-construction is prohibited for 24 hours. After the self-leveling cement mixing is completed, the cement in the barrel should be poured into the construction site as soon as possible, if the self-leveling of 2mm thickness is done, the self-leveling rake can be used to scrape, because the rake can evenly control the construction thickness of self-leveling; If you want to do self-leveling more than 3mm, you can use a self-leveling large spatula to do it. After scraping on the ground from the leveling, it should be deflated with a defoaming roller as soon as possible, and the scraping and defoaming construction personnel must wear spikes.
The construction of self-leveling is to retreat backwards while paying attention to the height difference between each barrel of self-leveling cement.
-
After the construction of the artesian plane coating, the normal room temperature can be used for two or three days, and a week later.
It's time to get on the device.
-
Two days is enough, and if you put heavy objects, it depends on the temperature conditions for 20-30 days.

Hello dear, I'm glad to serve you, and will try to help you answer it!How long after flushing to do self-leveling cement self-leveling strength will generally reach 70% within 24 hours after construction, 90% within 3 days, according to the phenomenon of different temperature, humidity and ventilation, self-leveling cement needs 8-24 hours after it can be completely dried, before drying can not be carried out the next step of construction. 2.
In front of the flat treasure cement artesian hall, the hardening speed is fast, you can walk on it after 24 hours, and you can continue to carry out follow-up projects (such as laying wooden floors, floor tiles, etc.) after 3 days. I hope I can help you, if you don't know anything, you can continue to ask, no need to end the consultation, I will answer for you as soon as possible, if you feel satisfied pro can help give a 5-star like, your satisfaction is my biggest motivation, thank you!

OK!!
Because the original foundation ground is uneven, the entire ground is leveled by self-leveling by doing 2 layers.
Self-leveling do 2 times It should be noted that:
1) After the first self-leveling leveling, the second pass cannot be done immediately;
2) After the first self-leveling is dry, the interface agent needs to be brushed again to do the second layer of self-leveling.
Same-living flooring Hope that helps

After the self-leveling ground is dry, the hardness is very high.
People will not easily fall off the layer when they step on it.
Hope that helps
I am not very clear about home improvement, I am more aware of the self-leveling ground in the clean area of the pharmaceutical factory, no need to take care of it, the advantage is that there are no gaps, it is very convenient to drag and sweep, but it is easy to clean it is not clean, because a little dust sticks to it will be very clear, self-leveling quality and handmade, the quality is good for 3 to 8 years, the quality is not good or 1 year will crack or peel, the handiwork is not good and it is particularly easy to blister, this drum is particularly ugly. In fact, epoxy self-leveling to put it bluntly is epoxy (resin) paint splashed on the ground to let him flow smoothly, is the paint will dry and crack after a certain period of time, peeling, if there is an oily substance dripping on it, it should be wiped off immediately, otherwise it will leave marks, and organic solvents such as nail polish remover will leave marks as long as they drip on it. Secondly, the clean area of the pharmaceutical factory is a perennial temperature of 18 26 degrees Celsius, and the humidity is maintained at 45 65 degrees
