Be careful when painting in rainy season.

There is no special requirement for the purchase of paint in the decoration and painting project in Meiyu season, but the paint construction is very strict, so the painting in Meiyu season needs to be cautious. If the painter must decorate in the rainy season, please explain a few points.

1, don't paint in rainy days.

When decorating in rainy season, whether it is varnish or nitrocellulose paint, don't paint in rainy days. A layer of water vapor will condense on the surface of wood products in rainy days. At this time, if you paint, water vapor will be wrapped in the paint film, making the surface of wood products turbid. For example, painting nitrocellulose paint in rainy days will lead to uneven color, and painting will lead to whitening.

If the painter is in a hurry and needs to do it, he can add a certain amount of white powder to the paint. Chemical white powder absorbs moisture in the air, which can accelerate the drying speed, but it will still have a certain impact on the engineering quality. Therefore, Bian Xiao, a Tuba rabbit, suggested not to draw in rainy days unless there are special circumstances. I'd rather let the construction team do other work or stop work for two days.

2, the rainy season blow be bored with child to extend the drying time.

Putty is a kind of wall material, which has the functions of waterproof, moisture-proof, anti-pulverization and anti-mildew. Before painting the wall, it usually needs to be scraped 1 to 3 times, during which the normal drying time is 1 to? Two days. However, when scraping putty in rainy days, you should first dry the water on the wall with a dry cloth and try to keep the wall dry. At the same time, according to the actual situation of the weather, the drying time of putty should be extended as much as possible, generally from 2 to? Three days is appropriate.

3, the rainy season decoration interval brush wall paint.

In general, it has little effect to brush latex paint on walls in rainy season, but the interval between brushes needs to be extended. If you finish painting for the first time, you should extend the drying time of the wall. The general time interval is about 2 hours. If it is rainy, it should be extended appropriately.

4, the rainy season paint "dry" need to be careful.

When decorating in rainy season, the painted surface dries slowly, sometimes it takes two or three days for a layer of paint to dry, and it can only be brushed for the second time after the paint dries. Some people will use fan blowing, air conditioning and other drying measures, not gas lamps or high-intensity lamps.

Painters should be careful when using whitening water in rainy season.

In the rainy season, wooden paintings will cause a layer of gray ash on the paint surface, which will affect the impression. Many people will use white water to remove it (Tianna water plus 5%- 15% white water), but the proportion should not exceed 20%, otherwise the paint will slowly dry and soften. However, when the indoor humidity is particularly high, if it still turns white after adding white water, it should be stopped.
