Flat has a chalky appearance in finish, absorbs light, and can make a color look slightly lighter. Semi-gloss/gloss will make a color look darker. The sheen will reflect the light, causing the color to be darker. Matte or eggshell usually the most true to color when considering finish.
You should be using flat paint on walls and areas that have a lot of bumps, scratches, or holes. Since it can conceal these blemishes easily, it'll be the one paint finish you'll want to be using. It's best for low-traffic rooms that have a ton of light like offices and more formal rooms, like dining rooms.
Painting in a flat, matte or satin finishes will soak up light, while semi-gloss, high-gloss and lacquer finishes tend to reflect light, which make a darker room feel brighter and lighter, said Edith Gregson, partner at DJ Ireland Interior Architecture & Design, an interior design firm in Washington DC.
Flat and Matte finish paints are ideal for covering walls that have flaws or blemishes. Even larger imperfections, such as extensive scuffs and nail pops can get covered and camouflaged since Flat Paints are effective at absorbing light, in essence, “hiding” the bumps and lines that exist on every wall.
It depends on the surface you are painting. For interior walls in high-traffic spaces like a mudroom, satin or eggshell finishes work best. Flat or matte finishes work best for most ceilings and semi-gloss is recommended for interior trim and doors.
If your wall has imperfections like uneven texture, patches or joints, flat paint will absorb light and make them less noticeable. However, flat finishes are not very durable and need to be carefully cleaned. Scrubbing flat paint could wear down the finish and cause sheen to appear in patchy spots.
From the perspective of a Color Designer/Consultant, I typically specify eggshell on walls for multiple reasons that benefit the people who are dwelling in the home. Eggshell paint cleans easier, covers better, wears better, and lasts longer than flat paint.
Flat paint works best in low-traffic areas, such as the master bedroom, a study, or a formal living room. “Be careful if you are someone like me who is constantly moving furniture around or has children with particularly grubby fingers—flat doesn't clean up quite as easily,” Henderson says.
But flat paints can be hard to clean since their porous texture can trap dirt and grime. And since flat paint doesn't resist water like glossier paint does, cleaning it may leave behind unwanted streaks that can make an already dirty wall seem even worse.
A paint color with a flat sheen can look lighter or darker than the same color with a satin or gloss sheen. While evaluating a color's appearance, you should also judge the effect of your preferred paint sheen.
Opting for a paint with a glossy finish is a great way to reflect light back into the space, making it feel brighter.
Light colors have an inherent reflectivity, which is why they can make a room feel bigger. Another way to achieve this—or to boost the already enlarging effects of a light color—is to go with an eggshell, satin, or semi-gloss sheen instead of a matte. Don't pair dark colors with a light trim.
Pros: Matte paint hides the imperfections and flaws of the painting surface, making it great for walls in your bedroom, dining room and living room. It is also great for ceilings and any sort of touch-up or remodeling work. Cons: It takes a lot of work to keep the imperfections hidden.
Flat or Matte
This can be great for touch-up work, as the flat finish will conceal many imperfections in your walls. A flat or matte finish is a great choice for walls and ceilings throughout your property. It's easy to touch-up, simple, and likely won't ever put-off potential renters (depending on the color).
Walls: We usually prefer to do two coats of paint on all walls whether or not we're using a paint and primer product. Why? Because it's far more difficult to mask flaws, even with flat paint, on an area as broad as a wall. Also, if we're using anything but flat paint, then a second coat is required.
Ideally, eggshell paint is best suited for ceilings, bedrooms, dining rooms and living areas where there is not a lot of dirt build-up or traffic. In addition, its medium-level durability provides added protection that a flat finish does not. For areas such as walls, eggshell works best and is easier to clean.
The eggshell finish gets its name from its similarity to the slightly matte appearance of eggshells. With a little more sheen than flat paint, eggshell finish is a great choice for bedrooms due to its softness and low reflectivity. Eggshell paint has grown in popularity due to its versatility in a variety of rooms.
If natural light and a room that feels larger are important to you then a lighter color is a great choice. If you rarely open your curtains and love to sleep in, then a darker color will help you create a cozy environment, like this example below (not one of our projects).
Flat paint can also be used on walls in low-traffic areas, such as formal living and dining rooms. It could also be a good choice for a home office space, depending on how much wear and tear it gets. You may even get away with using it in infrequently used guest rooms.
Poor quality of some trades, like drywall contractors, or framers, can make imperfections pop out if there is a sheen in the paint. Using flat paint keeps imperfections from being so noticeable.
A general rule of thumb is that a well-done interior paint job will last between 5-10 years, and potentially even longer. However, your paint's longevity is based on a bunch of different factors.
Flat has a chalky appearance in finish, absorbs light, and can make a color look slightly lighter. Semi-gloss/gloss will make a color look darker. The sheen will reflect the light, causing the color to be darker. Matte or eggshell usually the most true to color when considering finish.
Eggshell paint is a good choice for living rooms, hallways and bedrooms.
We recommend matte paints for bedrooms and as living room paint finishes where the walls are exposed to less moisture, choosing a glossier eggshell finish for kitchens and as a paint finish for bathrooms, which are more prone to moisture, as well as children's rooms, which might need more regular cleaning.
