The cement used for self-leveling floors of cement generally uses Portland cement, high alumina cement, and Portland cement. The self-leveling floor is made of water added to the material, which can be turned into a free-flowing slurry. It can be quickly spread on the ground and obtain high flatness from the ground, depending on the topography. Next, Xiaobian introduced cement self-leveling floor construction methods and cement self-leveling floor installation problems.
Cement self-leveling floor construction method
1, ground polishing
Before ground leveling using self-leveling cement, the ground first needs to be pretreated. There is usually a protruding place on the rough surface, which needs to be polished off. When grinding the ground, it is generally necessary to use a ground sander and flatten the bumps with a rotating flat mill.
2, brushing interface agent
The role of the interfacial agent is to allow the self-leveling cement to interface more closely with the ground. After the ground polishing process is completed and cleaned, it is necessary to apply two interface agents on the polished surface. There are many kinds of interface agents on the market, and the owner pays attention to selecting products with better quality to prevent various quality problems from occurring on the ground during the later period.
3, poured from the leveling cement
Self-leveling cement is a dry-mixed powdered material composed of a variety of active ingredients that can be used on site. Usually the proportion of self-leveling cement and water is appropriate. Make sure that the low water-cement ratio has a high degree of fluidity to ensure that the cement can flow, but it must not be too thin, otherwise the strength after drying is not enough, and it is easy to cause ash. After the interface agent dries, the stirred self-leveling cement can be poured on the ground. After pouring on the ground, the cement can flow along the ground, but it cannot be completely leveled. The construction personnel is required to push and open the cement with a tool.
Cement self-leveling floor installation FAQ
1, the floor damp breeding fungus
It is well-known that wood produces mildew and bacteria after rain. Similarly, the surface of the floor will appear black due to microbial growth after a long period of dampness. Of course, this situation is relatively rare in the case of wood floor damage, and the main culprit for the floor to meet the tide is that the base layer below the floor to the water Does not have good isolation function, resulting in prolonged exposure to the wet floor surface. The self-leveling itself has low moisture content, quick drying, etc. It also allows self-leveling to reduce free moisture in a short period. Wood floors laid on the self-leveling base layer can greatly reduce the reflection of moisture, which is in line with the standard of floor covering and survival. .
2, floor expansion, arching
Swelling and kicking are the most annoying and frequent problems on the floor. Smooth, clean floors often have a mound-like protrusion due to the arrival of rain and snow seasons. Many people encounter such problems and find floor manufacturers complaining about the poor floor quality. They do not know that there is a problem at the bottom of the floor. Due to the wooden nature of the floor, the local board will expand after being exposed to moisture for a long time, especially in the case of local moisture, due to the mutual compression between the floors, the arching phenomenon will occur. The main reason for this local moisture is very To a large extent, it is also due to the unevenness of the basement underneath the floor, or the unevenness of the moisture content. Self-leveling can not only prevent moisture and moisture on the ground, but also its excellent smoothness, evenness and flatness can avoid local dampness of the floor.
3, noise and floating feeling
How did this happen? It turns out that this is what is commonly referred to as floor bumps. There are two main causes of unevenness: First, ground level difference occurs due to uneven grounding at the bottom of the floor. This height difference results in floating after long-term stamping; Second, hollow phenomenon occurs due to weak connection between the basement floor and the floor. You can clearly hear unusual noises when you step on it. The leveling function provided by the self-leveling can eliminate the height difference between the ground and the floating phenomenon caused by the unconsolidated grass-roots level. It can treat the ground floor to a horizontal state and be permanently solid. With the self-leveling treatment of Dipingbao Cement, frequent stampings will be even as new.
4, the floor slot breaks
In recent years, locking technology has become popular in flooring technology. This kind of locking technology connects the floors tightly together. However, when the floor suffers from serious problems due to damp and arching, the buckle can be deformed or even cracked. After a good self-leveling treatment, the dampness of the floor is eliminated and the notches in the floor will maintain a good tightness.
5, leaks appear in the kicking foot
If the floor is suspended, the connection between the skirting board and the edge of the floor will be avoided. Because the suspended paving method is easy to cause cracks in the floor and the skirting board due to the weakness of the grass-roots floor, a series of later-stage hidden troubles such as water intake and dust intrusion will follow. Solid self-leveling has played a solid role at this time. It will never cause ground sinking problems due to long-term use. Naturally, there will be no difficult gaps between the baseboard and the floor.
6, the floor area from a large drum
It is also the phenomenon of kicking the floorboards. Drums and drums from large areas are caused by different reasons, or it can be said that the large-scale drums caused by inferior cement layering are more difficult to control and maintain. The quality of cement used by many home improvement companies or real estate developers is unqualified. Under long-term pressure, cracks or intermediate stratification can easily occur. Once this phenomenon is triggered, the entire floor will be completely destroyed. It is difficult to repair. Good cement is a good foundation. Solid self-leveling can also ensure the solidity of the grass-roots level and avoid ground problems caused by the fracture of the grass-roots level.
Editor's summary: The self-leveling floor construction method for cement and the common problems of self-leveling floor installation for cement are introduced here and I hope to be helpful to everyone. If you want to know more related information, you can pay attention to this website information.
