1, rain refused to paint

For wood products, whether it is brush varnish or nitrocellulose paint when mixing oil, do not remember to brush on a rainy day. Because the surface of wood products will gather a layer of water vapor in the rain. At this time, if paint is applied, water vapor will be trapped in the paint film, making the surface of wood products cloudy. For example, nitrocellulose lacquer on rainy days will lead to uneven color, while brushing will cause whitening. If it is necessary to meet the deadline, a certain amount of white powder may be added to the paint. According to professionals, white powder can absorb the moisture in the air and accelerate the drying speed, but it will also have a negative impact on the quality of the project. So under normal circumstances, even if the construction team has to do something else or stop working for two days, it should not paint as much as possible on rainy days.

2, the rainy season for the wall paint latex paint effect?

In the rainy season, the effect of wall paint latex paint is not great, but it is also necessary to pay attention to extend the time for wall drying after the first pass. In general, the normal interval is about 2 hours, and the rainy days can be extended according to the weather conditions.

3, to extend the dry time when scraping putty

The putty is the wall lining material we choose. This material is waterproof, moisture-proof, anti-powder and mildew-proof. To putty in front of the wall, you usually need to scrape 1 to 3 times, during which the normal dry time is 1 to 2 days. However, in the rainy days, putty should be wiped clean with a dry cloth to keep the walls dry as much as possible. At the same time, according to the actual conditions of the weather, the time for putty drying should be extended as much as possible, generally 2 to 3 days is appropriate.

4. What are the taboos for “drying” the paint during the rainy season?

In the rainy season, the paint drying speed will be very slow. Even a layer of paint takes two or three days or even longer to dry. In this case, you should wait for the paint to dry out, and you should not use gas lamps or high-intensity light for irradiation (except for the paint works only in partial construction).

5. What do you need to pay attention to when doing woodwork paint engineering in the rainy season?

Making a woodwork paint project during the rainy season will cause the paint to form a layer of grayish-white ash, affecting the perception. To solve this problem is not difficult, mainly in tan water to add 5% -15% of white water can be eliminated. (White water, also known as anti-white water, the scientific name of ethylene glycol monobutyl ether.), But the use of the ratio should not exceed 20%, otherwise it will cause the paint to slow dry and soft.

However, when the indoor humidity is extremely high, whitening phenomenon still occurs after adding white water, and the work should be stopped.
