How to level the wall?
A, metope leveling materials
Putty powder
Putty powder is powdery, which is a surface filling material that needs pretreatment before wall construction. The traditional process uses sodium cellulose, but it can only be used after being soaked in water for a long time. Putty powder is very soluble in water, so it can be used as long as it is stirred with water, which is very convenient.
Second, the wall leveling construction steps
1, wipe the wall
Clean up the peeling and crack position of the wall, repair it with cement mortar, remove the residual ash, and then clean up the wall. What we need to pay attention to is that the wall surface with strong water absorption should be wetted with clear water or sprayed with glue for back cover treatment.
2, the first blow be bored with child
We'd better prepare the base material of cement plastered wall, which can not only reduce the project cost, but also improve the construction quality. The preparation method of the base material: senior black cement and indoor putty powder are mixed evenly according to a certain proportion.
Generally, a steel scraper or spatula is used to scrape in batches according to the conventional method, and the scraping times should not be too many, usually twice. If you encounter a wall that returns to alkali, you can seal it with alkali sealing water first, and then use alkali-resistant putty powder as the first base material after the alkali sealing water dries, and then follow the normal steps.
3, the second blow be bored with child
After the first drying of the wall surface, it can be further scraped with putty for the second time. But the putty mixed for the second time is not easy to be too thin, and its water content is too large. It is necessary to ensure that the moisture after the second putty scraping is absorbed by the first putty as soon as possible, and the wall moisture can be calendered only after it is reduced to a certain extent.
Step 4 amend
The wall should be polished after leveling. Generally, you can use sandpaper to polish the wall or ceiling 2-3 days after brushing putty powder for the second time, and you need to brush white latex twice after polishing for the first time.
If white latex is brushed, the room is not ventilated, so that the white latex can be naturally dried, and it cannot be forced to dry. Forced air drying will lead to tiny cracks on the wall.
Precautions for wall leveling:
Avoid leaving traces during construction.
It is inevitable that construction workers will step on the concrete surface during construction. In order to ensure that shoes will not leave marks on cement, construction workers usually wear special shoes for construction. The sole of this kind of shoes is covered with nails, but it does not affect the stability, and it can also reduce the imprint on the cement surface.
Pay attention to finished product maintenance
Self-leveling and air drying are quick, and the wooden floor can be laid in three days. However, three days before drying, the finished product needs to be protected.
When choosing self-leveling cement, we should pay special attention to the shoes of left-handed workers. There is a layer under his leather shoes. Here, I will give my friends a brief description. The shoes below are simple. The sole is a layer of wood, and then there are two straps on it, so that we can put the "shoes" on our feet. Although the sole is covered with nails, it is very loose, but it is no problem to stand firm. The reason is that the construction work will walk on the cement surface, and such shoes will not leave traces on the cement.
The above contents are the introduction of how to level the wall surface, the construction steps of wall surface leveling and matters needing attention for your reference. Thank you for reading this article to have a certain understanding of how to level the wall, hoping to provide some help to friends who are leveling the wall.
