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.
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.
For the best results, your interior walls should be repainted every 3-5 years. If you remodel your home or change the style of a room, you may need to repaint sooner. Depending on your lifestyle, family, and your activities, you may have to paint more often to keep walls from looking dingy.
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.
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.
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.
Flat paint has more pigment than any other finish, which is why it's also known as concealer paint—it's also called matte paint. It's completely nonreflective, so the paint will soak up any light directed at it. Flat paint tends to be easier to apply than other finishes, and it also usually a less expensive option.
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.
Does matte paint scratch easily? Despite being forgiving of imperfections already present in the wall, matte paint finishes tend not to be so forgiving of scuffs and marks. For this reason, experts would usually recommend against using them in high-traffic areas.
Does flat paint wipe clean? 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.
The sheen of your paint can impact how quickly it fades over time. Flat, matte, and eggshell paints tend to absorb light more than satin or semi-gloss and, therefore, tend to fade sooner.
Eggshell, matte, and flat paints all absorb more light. This quality makes the paint color fade faster.
Everyone agrees that early morning is the absolute best time to begin a painting job. There is plenty of natural light streaming in, and you have hours to get the job done. When you open all of the windows and doors, you can control and minimize the “new paint smell” that you will have throughout the day.
Using flat paint means less work for builders and painters. BUT, flat paint is recommended for ceilings and very low traffic areas for a reason. It's not as durable or easy to clean as eggshell or other higher sheen paints.
You can't really go wrong with eggshell finish on your walls. Sometimes called satin finish, eggshell has slightly more luster than a flat finish, but you won't be left with shiny walls. It also resists stains better than flat and can be wiped with a wet rag.
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.
Tips for Cleaning Flat or Matte Paint Walls
Vinegar and water can soak into the paint and cause stains, discolor the paint, or even cause the paint to drip and run. Avoid using too much pressure when cleaning flat paint.
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.
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.
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.
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.
