The plum rain season decoration paint project has no special requirements for the purchase of paint, but the paint construction is very strict, so the paint should be cautious during the rainy season. If the painter must carry out the rainy season, let's take a few moments.
1. Do not paint on rainy days.
During the rainy season, do not paint when it rains, whether it is brush varnish or brush nitrocellulose paint. The surface of wood products will condense a layer of water vapor on rainy days. If the paint is painted, the water vapor will be wrapped in the paint film, making the surface of the wood products turbid. For example, brushing nitrocellulose paint in rainy days will result in uneven color, and when painted, whitening will occur.
If you are in a hurry, the painter needs to do it, and you can add a certain amount of white powder to the paint. The white powder absorbs the moisture in the air, which can speed up the drying, but it will have a certain impact on the quality of the project. Therefore, the Tuba rabbit Xiaobian suggested that, in special circumstances, do not paint in the rain. Would rather let the construction team do other activities or suspend two days of work.
2, the rainy season putty putty to extend the dry time
The putty is a wall lining material, which has the functions of waterproof, moisture-proof, powder-proof and mildew-proof. It is necessary to scrape the putty in front of the wall. Generally, it needs to be scraped 1 to 3 times, and the normal drying time is 1 to 2 days. However, when putting the putty on a rainy day, you should first wipe the wall with a dry cloth and keep the wall as dry as possible. At the same time, according to the actual situation of the weather, the time for the putty to dry out should be extended as much as possible, generally 2 to 3 days.
3, the rainy season decoration brush wall paint needs to be separated
Under normal circumstances, the Meiyu season decoration wall paint latex paint has little effect, but the painting interval needs to be extended. If the first time the paint is finished, the drying time of the wall should be extended. The general time interval is about 2 hours. If it is rainy, it should be extended.
4, the rainy season paint "drying" need to be cautious
During the rainy season, the painted paint surface is slow to dry. Sometimes it takes two or three days for a layer of paint to dry out. After the paint is dry, it is painted a second time. Some people will use the fan blowing, air conditioning and other drying measures, it is not appropriate to use gas lamps or high-intensity lighting.
5, the rainy season painter whitening water use caution
In the rainy season, the wood paint project will cause the paint surface to form a layer of grayish white ash, which will affect the look and feel. Many people will use white water to eliminate (add 5%-15% white water in the water), but the proportion should not exceed 20%, otherwise it will cause the paint to slow and dry. However, when the indoor humidity is extremely high, whitening still occurs after adding white water, and it should be stopped.
