My house has been renovated for less than a year, and the paint on the walls of the two bedrooms and

According to your statement, both are responsible. The developer should tell you how far the rough house sold to you has become. The decoration workers continue to work knowing that there is no sand rubbing and the paint may fall off, and they must bear the corresponding responsibility.

I developed my house.

In Hefei, you can find the master of Hefei Home Repair Network to take a look.

The current civil engineering code ceiling is not smoothed with mortar

It is obviously the denial of the decoration worker, which may be that the bottom putty is not dried or there is floating ash on the surface of the bottom layer during the decoration

Find a renovation company, yes, if it's really a developer's problem, why don't they tell you when they start renovating.

The key is to see whether it is a wall skin drum or a paint drum, if it is a paint drum, it should not be brushed with primer. If it's a wall drum, then you should find a developer.

Now the top of the building room generally does not do any treatment (the template is made very flat), should not be plastered mortar, if there is no plastering mortar then that is the time for decoration they in order to level, the roof with gypsum powder to hit the base, generally with glue will not fall, if it falls down is really even cement together, then it is the developer's problem, the roof is not plastered with mortar, it is a problem of decoration.

My friend works as a decorator, and I asked him this question.

It's the problem of the decoration company, the developer doesn't deal with it, the decoration company has to deal with it, you deal with it and charge a fee, and ask the decoration company to deal with it immediately.

This is the responsibility of the developer, which is caused by the high grade of cement or the wrong proportion of cement yellow sand. You can ask the developer for repairs.

Let's find a professional master, just say why don't you tell you to do sand rubbing first, it is difficult to find a developer, and not every house is taken off, why the developer has built so many houses on your house, if there is a problem, the decoration personnel should also raise it first.

It is also possible in general, there is also the worker who did not scrape the wall skin when you were constructing, or painted you without scraping the putty, and the third is that the proportion of water is too much when painting, maybe the proportion of water and paint is too large, and there can only be these few situations

See if the weather is too hot, it is generally recommended to decorate after one or two years after decoration. In this way, the wall is dry, the roof is also dry, and it is not easy to deform and crack after decoration. In addition, if it is a new partition or wall built by yourself, if you paint the wall together with the original wall, it will generally crack after a while, because the shrinkage is different, and cracks will occur.
