For the construction of water-based wood paint, it is very important to maintain the paint film to achieve good construction effect, especially in winter. If the paint film is not well maintained, the coating effect of water-based wood paint will be greatly reduced

1. Maintenance time of water-based wood paint film in winter

for water-based wood paint, there are basically two concepts from the curing time of its film: in summer, due to the high temperature in the air, the drying cycle of the film is generally seven days; In winter, although the air is dry and the humidity is not high, the weather temperature is low, so the drying cycle of the paint film is long, usually 14 to 20 days. The specific maintenance time depends on the specific local temperature

2. Precautions for the maintenance of waterborne wood paint film in winter

(1) pay attention to the dust protection of the construction environment. In winter, the climate is generally dry, the ventilation is not smooth, and the dust is heavy, which is easy to cause the problem of dryness and unevenness of the paint film. Therefore, during construction, it is best to close the doors and windows to prevent dust from being blown up by the wind and falling on the paint film

(2) appropriate equipment can be used to speed up the curing speed of the paint film, such as tungsten lamp irradiation, and heating construction can be considered in the north

(3) after the surface of the paint film dries, press it by hand on the paint film without tacking, and then open the doors and windows to speed up ventilation and drying

(4) in winter, although the curing speed of single component waterborne wood paint is relatively slow, with the extension of time, the film hardness will be higher and higher, so we don't need to panic

(5) avoid being close to heaters such as stoves and heaters, so as to avoid high-temperature baking, resulting in cracking of the surface of wooden furniture and peeling of paint film

(6) the maintenance time of the paint film is long in winter, so during the period when the paint film solidifies and reaches the real hardness, pay attention not to let hard objects scratch the paint film, or directly rub on the surface of the paint film, resulting in physical damage to the paint film

(7) if there are physical scratches during the maintenance of the paint film, there is no need to panic. You can use sandpaper to polish the surface of the scratched paint film, and then use Wole Waterborne Polyester Topcoat for brushing
