Choosing a colour takes most people weeks. Choosing the finish takes ten seconds and matters more for how the room actually lives.
Sheen — how much light the dried film reflects — is not a decorative choice. It controls two things that pull in opposite directions:
- More sheen = more durable and more washable.
- Less sheen = better at hiding an imperfect surface.
Every finish is a position on that trade-off. There is no finish that is both maximally scrubbable and maximally forgiving, which is why using one product everywhere always disappoints somewhere.
The finishes
Flat / matte. No reflection. Hides an uneven wall better than anything else, which is why it is the standard for ceilings and the default on older plaster. The cost is durability: traditional flat marks easily and often cannot be wiped without burnishing — leaving a shiny patch where you rubbed. Modern “washable matte” products have narrowed this gap considerably and are worth asking about.
Eggshell. A very low sheen. The usual choice for living rooms, bedrooms and dining rooms — it still hides most wall imperfections but tolerates gentle cleaning. For most homes this is the sensible default for walls.
Satin. Noticeably more sheen. Wipes properly, so it belongs where hands and moisture go: hallways, stairwells, children’s rooms, kitchens, bathrooms, and utility spaces. The trade is that it shows surface flaws, roller marks and touch-ups more readily, so it demands better preparation underneath.
Semi-gloss. Hard, cleanable, clearly reflective. This is trim, doors, frames, baseboards and railings — surfaces that get touched, knocked and cleaned. Also common in bathrooms.
Gloss. Very reflective, very hard. Used deliberately for a strong look on a front door, a feature piece of trim, or furniture. It magnifies every underlying flaw, so it is only as good as the sanding beneath it.
What goes where
- Ceilings — flat. Almost always. Ceilings are lit from below at an angle that reveals every imperfection, and flat is the only thing that hides it.
- Living rooms, bedrooms, dining rooms — eggshell.
- Hallways and stairwells — satin. This is the highest-traffic surface in the house and the one most likely to be regretted in flat.
- Kitchens — satin on walls, semi-gloss on trim. Grease needs to come off.
- Bathrooms — satin or semi-gloss, ideally a product formulated for moisture.
- Trim, doors, baseboards, railings — semi-gloss.
- Children’s rooms — satin, and you will be glad of it.
- Basements and laundry — satin, for moisture tolerance.
Why builder-grade paint disappoints
New homes are very often finished in a cheap flat wall paint. It goes on fast, covers in one coat, and costs the builder almost nothing.
It also scuffs when a bag brushes it, and cannot be washed — try, and you get a shiny mark where you wiped, which is more obvious than the scuff was.
This is why “the paint in our new house looks terrible already” is such a common complaint, and why the most frequent job in newer subdivisions is not repairing anything. It is replacing a finish that was never intended to last, usually with an eggshell on walls and semi-gloss on trim.
Touch-ups, and why they show
A touch-up almost never disappears completely, for three reasons:
- Sheen. A small brushed patch dries with a different sheen than a rolled wall.
- Colour. Paint changes very slightly as it ages and is exposed to light. Even the same tin does not match a wall painted two years ago.
- Texture. A brush leaves a different texture than a roller.
The higher the sheen, the worse this gets — which is another reason flat and eggshell suit walls. To give a touch-up its best chance: use paint from the original tin, apply it with the same tool used originally, and feather the edges rather than making a hard patch. On a badly marked wall, repainting corner to corner is genuinely the better answer.
Two things worth knowing before you choose
Keep a record. Write down the brand, product line, colour name, colour code and finish for every surface, and keep it somewhere you will find it in three years. A labelled tin in the basement is worth a great deal at touch-up time.
Ask what is going on your walls. “Premium paint” is not a product. A finish and a product name is an answer; a marketing adjective is not.
