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.
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.
However, it's the least durable choice and doesn't usually stand up well to scrubbing. The good news is, many paint formulas clean up easily with soap and water, but people still tend to shy away from flat paint in favor of other sheens that are easier to care for.
The solution was always to add a slight sheen, such as a matte or eggshell finish. However, these sheens always bring out imperfections that flat paint might not. Today, high-end flat paints such as SW Emerald, Duration, and PPG Manor Hall flat have excellent washability.
Eggshell and Satin
“Satin is slightly shinier, and both are easier to clean than flat or matte paint,” Handel says. You'll find that some paint lines offer both eggshell and satin.
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.
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.
One other thing to consider is that flat paint tends to attract dust more easily than matte paint does. So if you have a busy house, this might not be the best choice for walls or ceilings in high-traffic areas.
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 paint sacrifices some durability in favor of finish. Due to the makeup of flat paint, it tends to chip and flake easier than high gloss paint. So, if you have children, animals, or a high-touch area, then it's best to stay away from flat paint.
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.
This depends on whether you've maintained the proper storage conditions. New, never-opened cans of latex or oil paint usually last about three years. If you store a can of opened paint properly and don't expose the paint to air, it may last up to a couple of years.
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.
Try one of the versions of melamine-foam-based white sponges (“Magic Eraser” is one brand) –these are least likely to mar flat-painted surfaces, but due to their ablative action (they wear away) may leave a white residue on darker colors. Just follow them with an absorbent WHITE towel, using a gentle blotting action.
That means that Satin, semi-gloss, and High Gloss will be the easiest to wipe away blemishes without harming the surfaces. That being said, not many homeowners want their interior walls to shine at that level. Usually, Satin, Semi-Gloss, and High Gloss are left to cabinets, trim, and doors.
It is best to always seal furniture you paint where you used a low sheen paint like flat, matte, eggshell, or chalk paint.
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.
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.
The big difference between these two paints is the finish. Satin has a little sheen while matte is more flat. Satin is also more durable and easier to clean though it is trickier to apply and touch up if any marks do appear over time. Matte paint gives better coverage than satin and it's more cost-effective too.
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.
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.
The good news is that flat paint is easy to touch up. Matte paint is not recommended for bathrooms and kitchens, but it is ideal for living room walls, ceilings, bedrooms, and walls which have many imperfections. An eggshell finish has low sheen and is highly washable.
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.
