Mixing 3 parts thinner to 1 part paint?

Mixing 3 parts thinner to 1 part paint creates a diluted solution that can improve the paint's application properties. This mixture is often used to enhance flow, reduce viscosity, and increase the ease of spraying or brushing. However, it's important to ensure that the thinner is compatible with the specific type of paint being used to maintain adhesion and finish quality. Always test on a small area first to achieve the desired results.
