You are an old house. If there are no cracks in these places before decoration, it should not be the problem of cracking in the wall of your house, but the problem of decoration.
There are many reasons for cracking. Say a few main reasons and see which one you are:
1, before scraping putty and brushing latex paint, the paint on your original wall was not scraped clean, so the problem is more serious. It is recommended to shovel it off before scraping putty and brushing latex paint.
Besides, the workers have to work to catch up with the construction period. The putty should be scraped at least three times, and it should be completely dried before scraping. Latex paint is easy to crack in the later stage if it is not dry. If this is the problem, let the walls dry completely. It's almost time for heating. If you bake it with warm air, there will be more cracks After fully air-drying for a period of time, shovel off cracks, scrape putty and brush latex paint.
3, the putty is blown too thick, and it is easy to cause cracking. This reason is also solved by the solution of 2.
There is also the problem of uneven latex paint brush, which is also for several reasons:
1, after scraping putty, you need to smooth the wall with sandpaper. If it is uneven, then the latex paint will be deep and shallow.
2. The brand of latex paint used is different, or the concentration of each brush is too high, and the concentration ratio of each brush is too wide, which will also cause uneven color (white is the same).
3. The poor quality of latex paint is also a problem.
The basic solution to uneven latex paint is to grind it carefully with sandpaper, grind off the latex paint layer, and then brush the latex paint again after grinding the putty layer. It is suggested to use full effect or five in one, which is better for the problem wall.
The most important thing is the solution between you and the contractor.
If you look for a contractor, it means that you haven't found a formal decoration company, and you haven't signed a contract. It's no use suing them. I don't think they can compensate you, unless you have any non-legal solution, they can make such a low-level mistake to prove that they didn't do anything. What we call a "water cat" is nothing but waiting for a job by the bridge. If you find a job, organize people temporarily. Not everyone can work. I can't find anyone after work If you can only ask them to do it again according to my method, as for the labor cost and material cost, only you can negotiate it out. You'd better find someone who knows a little better to keep an eye on them for you, or I'm afraid there will be other problems. If you have this concern, just find a regular company to repair it for you, and spend money to buy lessons. You won't find a "water cat" in the future!
