In reality, the type of sheen you choose for your room can make a huge difference to your painting project. When 
choosing a paint sheen for your interior, it is very important to consider the area you are painting. Choosing correct paint sheen is almost as confusing as picking up a good paint color. So, a quick paint sheen guide is important to picking the right finish for your space.
There are different types of interior paint sheens including flat/matte, eggshell, satin, semi-gloss, and high-gloss. Before you select a particular one, it’s vital to understand the qualities that each one has to offer.
Flat, Matte, Satin, and Eggshell:
Flat and matte finish sheens are used in new construction and on ceilings since they have the ability to hide flaws. Matte and flat sheens don’t reflect light directly, as a result, any flaws in the wall and ceiling are much less noticeable. These types of low-gloss sheens are ideal for use on new drywall that contains any imperfections because of the flattening agent used in them. These types of finishes also have a UV blocker that helps reduce color fading.
Egg-shell paints are named so since they provide a finish similar to the surface of an egg. This creates a soft and tender finish. Satin sheens, on the other hand, provide a more reflective surface and are the best choice to resist mildew, dirt, and stains.
Semi Gloss and High-Gloss Sheens:
Unlike the flat, matte, satin, and eggshell sheens, semi-gloss and high-gloss sheens can provide your room interior with a bright, shiny look. Semi-gloss and high-gloss sheens are durable enough to last and are also aesthetically soothing. However, because they reflect a lot of light, glossy sheens show almost all imperfections in the interior walls or ceiling surface. Therefore, it’s best to use these sheens on areas with unmarred surfaces.
High-gloss sheens, offer high resistance to moisture. High gloss sheens could be the best choice when it comes to painting trim/woodwork, railings, window shutters, and molding. You can also use high gloss sheens on your ceiling to add a creative splash of light, but make sure the ceiling has no imperfections.
