Will Thick Paint Never Dry?
1 Answers
It won't never dry, but it is directly related to the season. In winter, using fast-drying hardeners, it takes more than three hours without heating, and within two hours with heating. In summer, standard hardeners are used, taking about one and a half hours without heating and around forty minutes with heating. Reasons for paint film not drying: Inappropriate hardeners were selected. Some auto paint shops and color-mixing stores use whichever paint is cheaper, leading to a mix of hardeners from different manufacturers with varying brands and solid contents, applied randomly, which causes issues. The painting environment is too cold, too humid, or has poor air circulation. For example, during the rainy season, the air is humid and rainy, making it hard even for clothes to dry, let alone paint. This is because the reaction between hardener molecules and paint molecules slows down, and the thinner evaporates slowly or even stops. The only solution is to use baking to speed up the paint film's reaction rate, thereby increasing its drying speed. Car maintenance precautions: Before using the vehicle, promptly remove dust from the body to reduce the car's static electricity from attracting dust. After rain, wash the car immediately. The concentration of acidic substances in rain spots on the car's surface increases significantly after rain, and failure to clean them promptly can easily damage the car's paint. When washing the car, ensure the engine is cooled down first and avoid washing under strong sunlight.
