Which type of paint finish is commonly used for exterior woodwork?

Semi-gloss or satin finishes are commonly used for exterior woodwork due to their durability and resistance to weather elements. These finishes provide a certain level of sheen that not only enhances the aesthetic appeal of the wood but also helps in protecting it from moisture, UV rays, and other environmental factors. The semi-gloss finish is particularly favored because it balances appearance and functionality, allowing for easier cleaning and maintenance compared to flatter finishes, which may absorb dirt and moisture more readily.

Satin finish offers a soft sheen that is less reflective than semi-gloss, making it suitable for wooden surfaces that might not require very high gloss but still need protection and ease of cleaning. Overall, these finishes cater to the need for both aesthetics and longevity in exterior applications.
