What is the term for paint that has been diluted with solvent?

The term for paint that has been diluted with solvent is "thinned paint." When paint is thinned, it typically means that a solvent, such as water or paint thinner, has been added to decrease its viscosity, making it easier to apply and allowing it to flow more smoothly. This is often done to improve the application process, enhance the finish, or meet specific requirements for the type of surface being painted.

Thinned paint can also provide better coverage and adhesion in certain situations, as it allows the pigment and other components to spread more evenly. Understanding how to properly thin paint is crucial in achieving the desired results in any painting project, whether it's for architectural, automotive, or industrial applications.
