Self-levelling cement flooring construction introduction
◆ Self-levelling cement construction procedure:
◆ Self-levelling floor structure:
1 clean base surface ──>2 brush water-based self-levelling special interface agent ──>3 amount of water (water ratio and the actual ground conditions) ──>4 self-levelling raw materials into the barrel ──>5 mixing ──>6 slurry pouring ──>2 m ruler to expand the control of the thin layer ──>8 deflated roller defoaming ──>9 levelling layer to complete the subsequent construction of the finishing layer.
◆ Packaging and storage:
Packed in moisture-proof paper bag, can be stored for 6 months under dry environment.
◆ General self-levelling levelling floor can be air-dried after about three days to install all kinds of flooring. During this period, you should avoid the wind blowing directly on the surface, and you can't walk on the ground within 24 hours.
◆There are many kinds of general self-levelling, including industrial type, household type and commercial type, and their difference lies in the strength of flexural and compressive resistance and environmental performance, so you should be careful in selecting materials!

The ground must be dry, moisture content measured with special test equipment does not exceed 17 degrees.
Grass-roots cement strength shall not be less than 10Mpa.
Construction preparation
Before the construction of self-levelling cement, it is necessary to sand the base floor with a sanding machine to grind off the impurities, floating dust and sand particles on the ground. Grind the floor level with more localised high rises. Sweep off the dust after sanding and vacuum clean.
Clean the ground, on the self-levelling cement must be treated with a surface treatment agent before, according to the manufacturer's requirements to dilute the treatment agent, with a non-delaminating wool roller according to the direction of the first horizontal and then vertical ground treatment agent evenly coated on the ground. To apply evenly, leaving no gaps. After coating the treatment agent according to the different manufacturers of different product performance, wait for a certain period of time can be carried out above the construction of self-levelling cement.
Cement surface treatment agent can increase the bonding force between self-levelling cement and the ground, and prevent the shelling and cracking of self-levelling cement.
It is recommended that the surface treatment agent be applied twice.
Apply self-levelling
Prepare a big enough bucket, add water strictly according to the self-levelling manufacturer's water-cement ratio, and mix the self-levelling with an electric mixer. For regular construction, mix for 2 minutes, stop for half a minute, and continue mixing for another minute. There must not be lumps or dry powder appear. Mixed self-levelling cement shall be fluid.
Try to use the mixed self-levelling within half an hour. Pour the self-levelling cement on the ground, use the target with teeth to target the self-levelling, according to the required thickness target to different sizes of the area. After it is naturally levelled, use the rollers with teeth to roll longitudinally and horizontally on it to release the gas in it and prevent blistering. Special attention should be paid to the levelling of the self-levelling cement at the joints.
According to the phenomenon of different temperatures, humidity and ventilation, self-levelling cement needs 8-24 hours to dry, and the next step of construction cannot be carried out before drying.
Fine sanding
A flawless self-levelling construction is not possible without a sanding machine. After the construction of the self-levelling is complete, the surface of the self-levelling may still have small air holes, particles and floating dust, and there may also be a difference in height between the doorway and the corridor, which will require a sanding machine for further fine treatment. After sanding with a vacuum cleaner to suck the dust.

Requirements for self-levelling cement construction floor base:
Cement mortar floor cement mortar ground should meet the design requirements of strength, according to the construction specification flatness should be less than within positive vice 5mm, no drumming, sanding, shelling phenomenon. The water content of the entire flooring foundation shall not be greater than 6%.
Old building renovation of marble, terrazzo, tile flooring, the surface is relatively smooth, there will be a certain amount of stains and oil stains after long-term use, the adhesion of self-levelling cement has a certain impact on the need to use mechanical grinding treatment. The loose crusted parts must be knocked off and filled with cement mortar. For marble and terrazzo flooring that does not meet the requirements of flatness, because of its hard surface can not be mechanically polished, it should be smoothed with self-levelling cement.
Construction process

Pake cement mortar surface can not have sand, mortar surface to keep clean.
The cement surface must be flat, with a height difference of less than 4mm within two metres.
