Therefore, the paint should be stored in a cool and ventilated place in summer, and the sealing of the storage container must be better. It is also necessary to keep away from open flames and wire sockets to avoid sparks from igniting the paint. It is generally recommended that the purchased paint be used within one month

2. Extend the drying time of wall putty. Before painting the wall, apply putty first, usually 1-3 times, during which the normal drying time is 1-2 days. In summer decoration, it is advisable to extend the time for the putty to dry out as much as possible, generally 2-3 days. Because the weather in summer is hot and wet, especially when the storm comes, the time for the putty to dry will be longer. In addition, when hanging putty, dry cloth should be used to wipe the water vapor on the wall to keep the wall as dry as possible, which is conducive to the painting of the wall

4. Paint the wall to avoid rainy days. When painting the wall in summer, it should be avoided in high humidity or rainy weather. Because during construction, the wall foundation is relatively wet, and the paint is painted before it is completely dry. Water seeps into the paint surface, causing the paint film to lose adhesion, causing the wall to bulge into a drum

5. Avoid exposure to the sun on the finished wall. In summer, the temperature is high and the sun is fierce. If the painted wall is often exposed to the sun, it is easy to make the wall color fall off, and the white wall will turn yellow. In addition, exposure to the sun will also cause the wall to heat up. When the wall temperature drops after painting, the paint surface will crack. Therefore, we must try our best to avoid exposing the painted wall to the sun
