At noon, the air humidity outside is at the highest value, and it is not appropriate to open the window, so it should be opened in the afternoon or evening, when the climate is relatively dry, open the window to adjust the indoor air.

2. Lime moisture absorption: on rainy days, quicklime can be wrapped in cloth or sacks and placed in various places in the room to keep the indoor air dry.

Hello, the reason why the wall you brush is always white powder is that your putty is not good, and if you brush the paint, the paint is not good

1. The old powder wall or the wall with anti-magnetic should be wet first, and then the basic coating should be removed and the interface agent should be brushed again.

2. New wall: first scrape putty twice - then polish the foundation - then brush the primer - and finally brush the topcoat two to three times can also be sprayed.

Precautions for wall scraping:

1.The construction of melamine coating should be thin but not thick, otherwise it will not only dry slowly, but also the smooth flatness of the coating after drying will be poor, and the melamine feeling will be weak.

2.The construction of melamine coating is generally not suitable for adding water to dilute, on the contrary, the glaze is weakened, the scraping is poor, the coating is dry and rough, and the scrubbing resistance is poor. If the coating is too thick, an appropriate amount of latex binder with the same performance can be added to adjust.

3.When scraping the melamine coating, each place can only quickly scrape 1 2 ports along the direction of the scraping batch, so that the scraped coating is thin and smooth and smooth.

4.For the decoration of the ceiling with gypsum line, when scraping the melamine paint, Sun Zhiying should scrape the straight edge of the gypsum line calendar plasterboard, and be careful not to scrape the plaster line, nor can it leave residue or pimples on the edge of the gypsum line.

5.When scraping the ceiling surface, it is generally the first horizontal scrape and the second vertical scrape, but when scraping the wall, it is best to scrape it vertically twice to prevent horizontal scratches.

6.When scraping the sunny corner of each wall, the sunny corner should be scraped straight and neat, and if necessary, the wooden board can be used to match the ruler with the scraping batch, so that the sunny corner after scraping is straight and neat, and the flute angle is distinct.

7.When scraping the melamine paint on the new wall, it is generally possible to scrape the batch twice to achieve smooth and white. When scraping the old wall, if the bottom layer cannot be completely covered after scraping twice, it should be carefully scraped again, so that the color of the scraped coating is consistent after drying, white and bright, smooth and smooth, and the melamine sense is strong.
