Can I brush latex paint in winter? What is the temperature requirement?
The minimum film forming temperature of latex paint is 0℃. When painting, the paint film is thin, which is easy to freeze and destroy latex particles in cold environment, and the film forming environment is low, which easily leads to incomplete film forming. The film formation of latex paint is a slow process, and it can only be formed at 25℃ for 7 days. Therefore, cold and rain should be avoided during film formation.
In the process of brushing latex paint in winter, the wall will crack and fall off. This is because the winter weather is cold, and there is moisture or condensation on the wall or surface. If the wall paint or primer is brushed directly without treatment, small bubbles will be formed and cracked when the temperature rises, which will lead to peeling and peeling of the wall in the later stage of construction.

Precautions for brushing latex paint:
1, the temperature is low in winter, so latex paint should be stored in a room with high temperature, not on the balcony or the north room to prevent freezing, and the brushing time should be between 10 morning and 4 pm, which is the best temperature period of the day.
2. When the latex paint is painted, the wall must be dry, and the newly completed wall will naturally dry for more than three weeks.
3, latex paint should be diluted with water in strict accordance with the manufacturer's instructions, excessive dilution, easy to cause paint film hiding power decline, color lighter, paint film powder off, performance decline, uneven gloss of paint surface, etc. Avoid excessive ventilation after coating and before drying of latex paint, forming strong convective wind, leading to surface cracking of latex paint.
