What is a key factor to consider when selecting paint for outdoor projects?

When selecting paint for outdoor projects, UV and moisture resistance is a critical factor because outdoor conditions expose paint to various elements, including sunlight and precipitation. UV resistance is essential in preventing fading and deterioration caused by sunlight, which can significantly reduce the lifespan and appearance of the paint. Moisture resistance is equally important, as it helps to protect against issues such as peeling, mold, and mildew that can arise from rain and humidity. Selecting a paint with high UV and moisture resistance ensures that it will maintain its protective properties and aesthetic for a longer time, making it suitable for outdoor applications.

Other factors, such as drying speed, opacity level, and texture quality, also play a role in the overall performance of the paint but are not as critical as UV and moisture resistance when it comes to outdoor durability. These other factors may influence application ease or the look of the finished project, but they do not directly address the challenges posed by outdoor environments.
