The quality of putty layer is very important, wall cracking, peeling, hollow drum, falling off and other problems occur, mainly because of the underlying reasons, rarely the quality of latex paint, so a good underlying is the key. What kind of walls need to be shoveled down?
1. "If you touch it with your hand, the hand will leave white" or "water spray, the water flowing is white". In this case, the putty quality is poor, so it is recommended to erase it.
2. Under the circumstances of empty wall, falling off and cracking, all these problems have been exposed. Of course, it is suggested to shovel and do it again, or to brush paint directly is to ask for trouble. If it is a local problem, it can be partially deleted and re-executed.
Someone will ask, I am a new house, not a second-hand house need to be shoveled out and done again? This is only about the wall quality, and has nothing to do with the second-hand house of the new house. At present, the raw materials are basically made of putty, but the quality is not necessarily good. Most of the materials and switches used for power and electricity are made of general materials. Because developers only need to achieve 60 delivery points, the cost is relatively low, and we need 90 quality points to live alone.
Some decoration companies, whether new or second-hand housing, all the suggestions are to dig out and redo, which is another extreme, or look at the quality of the wall, if the quality is good, save some money is good, especially some second-hand housing wall quality is very good.
Why do some decoration teams say that "no shovel effect is not very good", because shovel walls are more laborious, and some wages are not high, when labor is consumed. Because the wall problem seems to be normal decoration after one year, so the shadow of the decoration team can not be found, what matters to them.
