What are the different types of paint sheens available for purchase and how do they differ in terms of appearance and durability?

The main types of paint sheens are flat, eggshell, satin, semi-gloss, and high-gloss. Flat paint has a matte finish and is less durable but hides imperfections well. Eggshell has a slight sheen and is more durable than flat paint. Satin has a soft sheen and is easy to clean. Semi-gloss has a shiny finish and is very durable, making it suitable for high-traffic areas. High-gloss has a very shiny finish and is the most durable, but it can show imperfections easily.
