Cement self leveling matters needing attention

Prepare a large enough barrel, add water in strict accordance with the water-cement ratio of the self-leveling cement manufacturer, and mix the self-leveling thoroughly with an electric mixer. Stirring is carried out in two times, usually the first time about 5-7 minutes, the middle of the pause for 2 minutes, let the reaction, and then stir for about 3 minutes. Mixing should be thorough, no lumps or dry powder. The stirred self-leveling cement shall be fluid. Mixing good self-leveling as far as possible within half an hour of use. The self-leveling cement poured on the ground, with a toothed target to open the self-leveling target, according to the requirements of the thickness of the target to different sizes of area. After its natural leveling with toothed rollers in the above vertical and horizontal rolling, the release of the gas, to prevent foaming. Special attention should be paid to the leveling of the lap joint of self-leveling cement. According to the phenomenon of different temperature, humidity and ventilation, self leveling cement need 8-24 hours after completely dry, dry before the next step of construction.
1. The floor will be affected with damp and breed fungi. After being affected with damp for a long time, the floor will turn black due to bacteria. The root cause of the floor is that the base layer below the floor does not have a good isolation function for water, resulting in the floor contacting the wet base surface for a long time. Self leveling treatment is a good solution to this problem, because the self leveling itself has low moisture content, quick drying and other characteristics, therefore, the wood floor attached to the self leveling base can greatly reduce the phenomenon of moisture.
2, floor expansion, arching due to the wood characteristics of the floor, the local board will produce expansion after a long time damp, especially in the case of local damp, but also due to the mutual extrusion between the floor, resulting in arch phenomenon. Self leveling treatment will put an end to the occurrence of this phenomenon, it can not only on the ground moisture, moisture, its excellent finish, uniformity and flatness can also avoid local damp floor.
3. The floor is trampled with noise. After the wooden floor is used for a period of time, it will produce noise and air floating, which is called the concave-convex phenomenon of the floor. First, due to the uneven grinding of the lower base of the floor, the ground height difference is generated, which is floating after long-term trampling. Two is due to the lower floor between the base and the floor connection is not strong and hollow phenomenon. Leveling provided by the leveling function, can put an end to the ground height difference and due to the grass-roots is not solid floating phenomenon.
4, the floor notch fracture in recent years, the lock technology in the floor process, the lock technology will be closely connected together, but in the floor due to damp arching problem occurs seriously will cause the lock buckle deformation, or even collapse. If the self leveling good treatment, put an end to the floor damp situation, the floor between the slot will maintain good tightness.
Cement self leveling in the construction, there are many problems to pay attention to, only pay attention to these, in order to better construction of cement self leveling. At the same time, if you have no actual construction experience, be sure to ask some experienced masters.
