What is the difference between latex and oil-based paint for home exteriors?

# Latex vs. Oil-Based Paint for Exteriors

Latex (Water-Based) Paint: Latex is the modern standard for exterior work. It's easier to apply, dries quickly (1-2 hours), and has low odor and low VOC (volatile organic compounds), making it safer for you and the environment. Cleanup is simple—just soap and water. Latex paint is also more flexible, which helps it expand and contract with temperature changes, reducing cracking. It's breathable, allowing moisture to escape, which prevents peeling. Most contractors today prefer latex for residential exteriors.

Oil-Based Paint: Oil paint provides a harder, more durable finish and traditionally gave excellent adhesion on glossy surfaces. However, it takes much longer to dry (6-24 hours), has strong odor and high VOCs, and requires harsh solvents for cleanup. Oil-based paint is less flexible and can crack in temperature swings. Many areas restrict oil-based exterior paints due to environmental regulations, and fewer contractors stock or apply them anymore.

Bottom Line: For most home exteriors, latex is the better choice. It performs well, lasts just as long, is easier to work with, and is better for the environment. Oil-based paint is rarely needed unless you have a specific surface that requires it—which a local painter can assess for you.
