High temperature and high humidity weather water-like wood paint construction, do not ignore these problems

China Paint Online News Information: High temperature or high humidity climate for water-based wood paint construction often produces some abnormal problems: such as paint film wrinkle, paint film adhesion, paint film cracking, paint whitening, etc. , these will affect the progress of construction and decorative effect. So, in the high temperature and high humidity under the world to carry out water-like wood paint construction, what problems should be paid attention to?
1. Paint film wrinkle
water-like wood lacquer film at high temperature will be quickly dried, while the thick inner layer is dry slowly, in the drying process the flow of paint produces a difference in tens of pressure, resulting in the final film surface uneven, that is, we often say wrinkle. Therefore, the construction should not be a molding, should take a thin coating, to ensure that the coating evenly dried into a film, to achieve the effect of paint film flat.
2. Paint film adhesion difference
in the high temperature, high humidity environment, the general water-like wood paint construction will find that the coating between the bonding is not secure, resulting in poor adhesion between the layers, the emergence of layers and layers of mutual peeling, and even like tearing off the whole piece, resulting in poor adhesion between the lacquer film layers. The direct cause is the lack of polishing between the layers of the painter's construction. Therefore, in the high temperature weather construction, each floor should be fully polished to enhance adhesion, while the construction arrangements in the morning and evening is appropriate to ensure that the quality of the product is reflected.
3. Paint film cracking
this phenomenon is also more common in high-temperature construction, because in the process of construction, the paint coating film is too thick, resulting in the surface dry film fast, while the thick inner layer is dry slowly, directly caused by paint film cracking and other phenomena. At the same time, we should pay attention to the quality of the plate, it is recommended to buy stable plate.
4. The paint layer is white
mainly due to the construction environment humidity is too large, the construction process paint film is too thick and other reasons. Because of the high temperature, air humidity in some areas, paint surface drying time with the increase in temperature and speed up, but the dry time is relatively slow, painters in the construction process will often ignore the dry time, and after the paint surface dry immediately after the next construction, resulting in the bottom paint layer is not fully solid. In heavy rain or humidity, the most likely to produce the phenomenon of whitening paint layer.
