What is an important characteristic of oil-based paints?

An important characteristic of oil-based paints is that they have long-lasting colors and require solvents for cleaning brushes. Oil-based paints are known for their durability and rich, vibrant colors, which can provide a more intense finish compared to other types of paints. Once dried, oil-based paints form a tough, durable surface that can withstand wear and tear, making them popular for both interior and exterior applications.

The requirement for solvents, such as mineral spirits or turpentine, for cleaning brushes is a key feature of oil-based paints. These solvents are necessary because oil-based paints do not dissolve in water, which makes cleanup more involved compared to water-based paints. This characteristic highlights the need for special handling and cleaning procedures when using oil-based products in stagecraft and other painting applications.
