Best Temperature to Paint a Car

2nd Sep 2022

Car painting is not to be underestimated. It’s a complex skill requiring a steady hand, lots of knowledge, and superb attention to detail. The skill is so unique that car painting contests exist throughout the world.

However, whether you are a professional or an amateur, you need the right temperature to finish the job. Keep reading to discover the best temperature to paint a car, whether you are painting outside or in automotive paint booths.

The Ideal Temperatures for Paint Booths

The goal of a car painter is to be invisible. In other words, to seamlessly apply colors, making sure they match the owner’s vision or the previous color palette. And temperature plays a significant role in a successful painting job.

Generally speaking, the lowest temperature you should paint a car at is 55 degrees Fahrenheit. Most paint manufacturers recommend 70-degree temperatures and 50% humidity for painting inside your auto painting booth. However, the exact recommended temperature will depend on your paint type.

Water-based paint requires 5-degree hotter temperatures in your booth than the outside. For instance, if it’s 85 degrees outside, set your booth to 80 degrees. With solvent-based products, it’s an entirely different situation. In this case, adjust your paint booth's humidity and temperature control system to match the conditions outside. So, if it’s 80 degrees outside, make sure it’s the same inside your booth.

The Ideal Temperatures for Painting Your Car Outdoors

When it comes to the best temperature to paint a car outside, you should also avoid cold temperatures. The minimum is 55 Fahrenheit, while the ideal range is between 60 and 80 degrees. The ideal humidity is 50%, but an appropriate range is between 40% and 70%. When painting outside, you should also avoid windy weather as it can cause the paint to dry too quickly.

Why Not Paint When It’s Cold?

Sure, you can try to paint in colder weather (below 55 degrees). However, this will significantly influence the final results. Cold temperatures prevent the paint from properly sticking to the surface as it might become grainy or even freeze if you paint with latex or other water-based paint. So, it’s simply impossible and unnecessary to paint your car in cold weather.

When Is It Too Hot To Paint a Car?

Car painting can be just as inefficient in extreme heat just as it can be in extreme cold. Plus, high temperatures and high humidity will not only affect car painting quality but can also threaten the painter’s health. After all, it’s still a task requiring a lot of physical effort.

So, don’t paint in over 85% humidity or 100 degrees Fahrenheit environments. Painting in these conditions is also considered as pushing the limits, but if you must, make sure your booth has excellent ventilation.
