A car should not be washed until at least 48 hours after painting. Exerting excessive external force on uncured paint, which is still in a liquid state, can cause the uncured paint to peel off. Additionally, some car paints are soluble in water, and when mixed with water, the paint becomes diluted, altering the original paint composition and color. Paint curing involves both the paint itself solidifying and the curing agent playing a role. The ratio of the curing agent to the amount of paint is usually fixed, and complete curing typically takes 48 hours.
When it comes to touch-up painting, the duration may vary. For touch-ups that do not affect the metal layer, typically involving adjusting the color paint and clear coat, washing the car is not recommended the next day as the paint surface has not fully cured. For touch-ups that affect the metal layer, the curing time may be longer. Before touch-up painting, it may be necessary to apply putty to make the damaged area smoother compared to other areas. The curing time of paint is influenced by various factors, including the amount of curing agent, temperature, humidity, etc. It is advisable to wait 48 hours after painting before performing any other form of paint maintenance.
Car paint not only protects metal components but also contributes to aesthetics. Proper maintenance can enhance the durability of the paint. When washing a car, it is recommended to avoid washing it in direct sunlight, as dried cleaning agents can easily leave marks on the new car paint. Use a specialized neutral water when washing, avoiding the use of highly alkaline soapy water to prevent washing away the grease in the new car paint. When taking the car to a car wash, ensure that the car wash staff does not use wax-stripping detergents, as they can potentially harm the paint surface.
