PuTTY is a key step in the renovation process because it is an important issue for whether the wall will crack later. A few days ago, some owners responded to the large area of ​​latex paint on the roof surface, which caused a mess in the home. It was identified because at the time when the home was made latex paint, the coating left by the developer was not eradicated. However, the current mainstream technology is not shovel, so the owner is very confused about whether to remove the coating left by the developer before the putty.
To this end, the reporter interviewed professionals, Chenguang coating related responsible person said that the current mainstream technology is not shovel, but the need to deal with the coating left by the developer, if the owner of the renovation project requirements, quality, etc. are very high , it must be shoveled. He thinks wet and empty drums will cause shedding. The construction of the roof is recommended to use a scraper to scrape. However, once the scraper is thick, it is likely to crack or fall. The leveling of the ceiling is very important. Now many designs use the lamp trough and the light trough has a dozen. The uneven top is very obvious. To level the top requires some technical processing.
The supervisor said: "The shovel does not depend on the actual situation. After the wall tide, if it is easy to shovel it, it must be shoveled. If it is very firm, it will not require shoveling. With or without shoveling, the walls must be treated at the grassroots level. The division also said in the inspection of the room that the best shovel, if you do not shovel, even if you do not see now, a long time the wall and the top surface will be cracked, but the high price of the shovel wall, generally about a thousand.
The netizen “Winter in the Summer†tells everyone a good idea: The walls of the house must be shovelled, shoveled to the black cement layer, and then the mesh crack-resistant cloth is to be puttyed again, so that the cracking coefficient will be much smaller later. "If you do not remove the coating, even if there is no large-scale shedding phenomenon, cracks are inevitable." There are a lot of renovated owners also told reporters that at that time because there was no eradication, the results of a large area of ​​wall paint fall off, and finally only Secondary wall painting, so he reminded to be sure to eradicate the developer's coating.
Although some people in the industry say that there are some discrepancies, and the shovel coating has also increased the cost of renovation to a certain extent, but in the long run, it is very necessary to eliminate the coating left by the developer. It reduces the chance of cracking on the wall and the top surface in the future.
