2, vertical illumination leveling. Need to use gypsum glued into a cake as the construction of the base point, and the distance between the base point shall not be less than two meters, and then use the level to calibrate, so that you can make the wall and the ground and the shed to maintain a double right angle.
3, find square. The process needs to pop up a square pop-up line on the wall first, and then in accordance with the strict construction process for construction, you can make the wall to maintain a flat state.
Types of wall leveling
1, looking for smooth
Looking for smooth application in the same wall unevenness over the prescribed range. In other words, the data is every 2 meters of flatness error does not exceed 3mm. find smooth construction process is relatively simple. It is only necessary to mix the gypsum, apply it to the wall with a tool, and then scrape it with an aluminum alloy ruler. If the degree of concavity is a little deep, it is recommended to construct again. The process of testing the master's construction techniques, do not pay attention to the effect is not good.
2, vertical leveling
Vertical leveling of the content of the work, as opposed to find a smooth flat, then more complex. Not only to deal with the flatness of the wall in a timely manner, but also to ensure that the double right angle of the wall floor.
①Pointing
It sticks the plaster into a cake as the construction base point, and the distance between two base points should not be less than 2M. the highest point of each base point should be calibrated with a level so as to keep the vertical.
②Punching rib
It is based on the punching point, the two base points will be connected to a vertical plaster band, the thickness of the plaster band should be higher than the thickness of the punching point. When construction, eight-eight application method is used, and the width is usually within 50mm.
③Scraping
Completed the second step, it is necessary to use a ruler to scrape, scraping the height of the base point height to be flush.
4 leveling
Fill the plaster between the gypsum tape, in the scraping ruler from the bottom to the top, a little upward leveling.
5 Repair
It's not that easy to put it in place at once. Therefore, we have to check carefully, and if we find that the plaster is not enough, we have to replenish the plaster immediately and scrape it again after the completion of the project.
3, looking for square
The general process of looking for square and vertical leveling is a bit similar, but the overall requirements of the construction is more stringent. The main difference is that before the first step there is more than one square elastic line.
The main difference is that before the first step there is an additional square bouncing line.
