Self-leveling to be level, no noise on the wooden floor地面装饰家装的一个重要组成部分,木地板感觉自然,舒适美观,安全环保,因为质感,有极好的灵活性,导热系数小,夏天很凉爽,营造一种温馨而宁静的感觉为居室,越来越受大众的青睐。然而木地板不能离开地面的铺设平整,如果地面不平,空环,时间一长满足尖叫声后铺设木地板,上升甚至翘等现象,不仅影响木地板和生活质量,还影响心情。
Floor decoration is an important part of home decoration, wooden floor feel natural, comfortable and beautiful, safe and environmental protection, because of texture, excellent flexibility, small thermal conductivity, cool summer, create a warm and quiet feeling for the living room, more and more popular. However, the wooden floor can not leave the ground laying flat, if the ground is uneven, empty ring, a long time to meet the scream after laying wooden floor, rising or even warping phenomenon, not only affect the wooden floor and quality of life, but also affect mood.
The planarity of the installation foundation of wooden flooring is demanding. For the level of home decoration flooring, it needs cushioning level. Using self-leveling high-precision leveling technology is an effective scheme to improve the installation quality of flooring and half the effort. With the improvement of people's requirements for quality of life, more and more homemade floors will be made of self-leveling cement cushion. Floor installation guru is widely known: self-leveling cement is uniform, wood floors are silent. But many people are confused about the self-leveling of cement. My little sister takes you to look for it.
1. Is cement self-leveling at ground level?
In the construction of cement self-leveling, special attention should be paid to the difference between flat ground and super-horizontal ground. The so-called flat ground refers to the ground after construction. Although the whole ground is flat, it is not necessarily horizontal. Ultra-flat ground is the ground on the same level as the whole ground. The construction process of super-plane is very complicated, so it is necessary to determine the horizontal point, and then construct according to the horizontal point. Except that the thick self-leveling layer can be used as a horizontal surface, most of the other surfaces are flat.
2. Will the self-leveling construction produce (chromatic aberration)?
Self-leveling chromatic aberration is caused by inconsistent control of self-leveling fluidity during construction. Excessive water will cause surface bleeding and color aberration after hardening. Under normal conditions, the color difference will be lighter after use. But the color surface self-leveling should not appear chromatic aberration.
3. Can ground grinding be self-leveling seriously?
Can do it. The cement self-leveling can be achieved by using permeable interfacial agent.
4. Is self-leveling construction fast?
The self-leveling of cushion cement has low requirement for surface effect, inaccurate water addition and fast construction speed. On average, each person can mix 500 to 800 square meters per day, and mechanized application can reach more than 1000 square meters. The self-leveling construction of the color surface layer should be very fine. Construction speed is much slower than cushion. An average of 200 to 300 square meters per person per day can be built.
5. How to check the horizon?
1. No empty drum: Cement mortar surface and base should be firmly bonded, not empty drum.
2. Surface compaction: The surface of cement mortar should be compacted and polished, without cracks, spalling, sand removal and other defects.
3. No flood: Floods on the ground are not flooded. Floods should be made according to the design requirements, and there should be no backfilling flood.
4. Sand layer: usually find cement ground, sand layer ratio should be appropriate, leveling the ground to sand layer.
