Ground leveling process (self-leveling technology)
At present, there are three main methods for ground leveling: cement mortar leveling, self-leveling leveling, and gypsum leveling. Among them, self-leveling is the best, but its price is relatively high. With the development of technology, self-leveling and leveling technology will become better and better, and the price will gradually become equal to the leveling price of cement mortar, making it the first choice for future ground leveling methods. Since self-leveling is the best way to level the ground, it is naturally highly sought after during the construction process. Today we will come to understand the self-leveling process.
Home decoration Now we will talk about the construction steps for self-leveling ground leveling. The general flow includes the following steps: Primary surface treatment → Brushing interface agent → Self-leveling → Roller infiltration → Finished maintenance.
| First, the basic surface treatment: grinding the ground |
Generally, there is a relatively protruding place on the ground of the house, and the place where the high place can be polished by means of a rotary flat grinding method is that there is no pipe below. If the high place is not polished, then the leveling ground will appear to be scraped by the teeth of the ground in the same high place, leaving behind the same amount of cement, and finally found out that the ground is good and still high, low The place is still low. At the same time grinding can save a lot of materials, which is a very important step in the ground leveling.
| Second, coating interface agent |
This step is to paint the interface agent. Firstly, apply two interface agents on the smooth ground surface. The interface agent is actually a glue, and the function is to make the self-leveling cement more tightly connected to the ground. note. There are many kinds of interface agents on the market. The counterfeit products are very serious at present, and some guerrilla construction teams are easy to use the interface agents that have poor water quality after they are leveled. As a result, many problems arise on the ground. For example, from the empty, sand and so on. Therefore, ground leveling as an important ground treatment before floor installation must not be used to find guerrilla construction. Otherwise, the consequences may be very painful.
| Three, self-leveling cement |
According to the worker's introduction, self-leveling cement and ordinary cement have the same appearance but different effects. Ordinary cement is usually used in conjunction with sand, in order to prevent the cement from being cracked due to its high strength, while the use of pure cement is rare, and the use of cement is rare or extremely thin. The use of pure cement must be carried out after the maintenance, otherwise it will certainly crack.
Self-leveling cement, as the name suggests, must be able to flow, but it must not be too thin, otherwise the strength after drying is not enough. Usually the ratio of self-leveling cement to water is 1:2.
Here we must also pay special attention to the shoes of the left worker's master. Underneath his leather shoes, there is a layer. Here is a brief description for friends. The following shoes are very simple. The sole is a layer of wood, and then the above Two belts, so that you can put the "shoes" on the feet, and the soles are covered with nails below, but it is very loose, but it is a steady problem is not. The reason is that during the construction operation, the cement surface will walk, and such shoes will not leave a mark on the cement.
