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.
Flat, eggshell and satin paint are best for interior walls, whereas semi-gloss and gloss paint are best for trim and woodwork. An eggshell finish has a subtler shine to it, so it's a great choice if you're not ready for satin.
On Walls. 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.
Flat paint will always be better for builders and painters. It costs less, downplays flaws in drywall, and can be touched up easily without showing roller marks. In new builds, it is almost always used by builders and painters. Painters often paint rooms that require modifications after initial painting.
If your space has huge windows and lots of natural light, a flat paint finish can work well. If you want something more shiny and reflective, choose satin or semi-gloss. If you don't want your walls totally lustrous, you can paint trim or crown molding with a semi-gloss sheen.
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.
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.
In many such situations, the builder, seller, or low-cost painter used a low-grade flat paint for three reasons: the first is that it is inexpensive; the second is that it is easy to touch up; the third is that it hides imperfections in the drywall walls.
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.
We advice that when painting the living room, you use eggshell and satin sheens. While flat paint is best for hiding surface imperfections and is easy to touch up, satin sheens offer a nice gloss and are easier to clean. Eggshell is more durable than flat paint, but not as shiny as satin paint.
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.
The unfortunate answer is that it probably won't work great. Bathrooms tend to be moist places, and flat or matte paint will begin to grow mold or mildew much faster than other paint sheens. Also, it doesn't resist stains very well, and it is somewhat hard to clean.
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.
Type of Paint to Use
Avoid using flat or matte paint on doors. Each door is 68 square feet, including front, back, and edges. One gallon of paint covers about 350 square feet. So, you'll need about one gallon of paint for every five doors.
The difference between flat and matte paint is so small they're largely interchangeable. Ultimately, it comes down to gloss level. Flat finish has an ever so slightly lower gloss percentage, around 5%, with matte finish around 5-10%. Even though it's small, this difference does affect durability.
In general, interior paint will last from 5 to 10 years. You can expect your exterior paint to last between 5 to 7 years. Keep in mind that your exterior paint will be affected by regional climate conditions, the material painted, and the type of paint used.
The flat low-end paint is very porous. Due to the porosity; the liquids (vehicle) of the new paint being applied are absorbed in some areas, more than others, leaving the binder partly exposed and an uneven finish.
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.
If you cannot see any light bouncing off the finish of your painted wall, you have flat paint. Unfortunately, flat paint is much quicker to show scuffs, smudges, and fingerprints than other types of paint finishes. It does not hold up well to moisture, which is why it is seldom used in kitchens and bathrooms.
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.
Painting Tip: It is important to avoid using flat paints or alkyd paints in humid or outdoor spaces because these paint finishes are more prone to damage, discoloration, and wrinkling, which can lead to new mildew growth.
Satin finishes are the most commonly used paint for interior walls. They are easier to clean than flat and eggshell paints, which makes them a great choice for high-traffic areas like kitchens, bathrooms, family rooms, and playrooms.
Typically, we recommend using matte on walls in lower-traffic areas like master bedrooms, dining rooms, or living rooms that won't get dirty or scuffed up as often. Moreover, flat and matte paints are easier to touch up and apply, which makes them ideal for novice painters or DIY projects.
You can wipe flat paint clean, but you'll want to use a light hand so you don't remove any paint along with dirt and debris. Wipe the walls with a dry cloth and then run a sponge soaked with warm water over any stains. Don't scrub. If the stain doesn't lift, try adding a few drops of gentle dish soap or detergent.
