Eggshell and flat paints are used to fulfill different objectives. First, let’s discuss the difference is between flat paint and eggshell paint. Flat paint is also referred to as matt paint and tends to absorb light. It is useful in covering minor faults in the surface, but the disadvantage is that it can be a little rough and is not easy to clean. Eggshell paints, on the other hand, have a glossy finish and tend to reflect light. If your wall has many imperfections that you want to hide, then flat paints are the right choice. However, if you are looking for durability and easy maintenance in spaces where there is high traffic, then eggshell paints are the best option for you.
