So here we go…
Flat or Matte - Has virtually no shine and has an almost chalk look to it. It is good for hiding imperfections on a surface but if you have kids or pets, use this one on the ceiling only. In new homes, it is often the choice of the contractor because it is the least expensive. That lack of resin, that creates shine in a paint also makes it hard to clean, and subject to stain.
Eggshell - Slightly more sheen than a flat paint and more washable too. You could use this in a dining room, master bedroom or any room that doesn’t get a lot of traffic. It reflects light better than flat paint does to give a soft lustre.
Satin - A satin finish can have a pearl effect. It can be used in moderate to heavy traffic areas like living and family rooms, hallways, kitchens, trim and shutters. You could also use when painting furniture.
Semi-Gloss - Semi-Gloss paint is great for high traffic, high use areas. Paint your kitchen, woodwork, trim, and doors in this highly scrubbable paint. This paint has a medium reflecting value and because of that will show any nicks or imperfections.
High Gloss (Sheen) - This paint has a very shiny almost glass-like finish. It is very on trend for bedrooms and dining rooms to give that laqcured look. It has a high durability and can also be used in high traffic areas like kitchens, trim, cabinetry, doors and shutters.
