Understanding the Sheen Scale
Paint sheen refers to how much light the cured paint film reflects. It runs from completely flat (no light reflection) at one end to high gloss (maximum reflection) at the other. In between, from low to high, are: flat/matte, eggshell, satin, semi-gloss, and gloss.
Here's what matters about this scale beyond aesthetics: higher sheen = harder, more washable surface. Lower sheen = softer surface that hides imperfections but doesn't clean as well. That trade-off is what drives the choice for each room. You're balancing how the room looks with how durable and maintainable the surface needs to be.
Flat/Matte: Where It Belongs (and Where It Doesn't)
Flat paint has zero reflectivity. It gives walls a soft, velvety appearance that many designers and homeowners find sophisticated — it makes colours look rich and depth-y in a way that glossier finishes don't. The drawback is that flat paint is not washable in any meaningful sense. You can dab at a fresh mark with a slightly damp cloth. But actual cleaning — wiping down a scuffed wall, removing a grease mark in the kitchen, dealing with fingerprints on a hallway wall — will remove the paint film along with the stain.
Where matte works well: Ceilings (almost always — ceiling paint is typically flat). Adult bedrooms with low traffic. Formal living or dining rooms that aren't heavily used. Accent walls that you want to look particularly rich and deep.
Where matte fails: Kitchens, bathrooms, hallways, kids' rooms, any surface that sees regular cleaning. If you have flat paint in your kitchen and you've tried to wipe something off and ended up with a dull patch that shows cleaning marks, this is why.
Eggshell: The Workhorse Finish
Eggshell is probably the finish I use most often on residential interiors. It has a very low sheen — not quite matte but barely reflective, similar to the surface of an actual eggshell — and a significantly harder cured film than flat paint. It can be cleaned with a damp cloth without the surface degrading, which makes it practical for virtually any living space.
In most Toronto homes — whether a detached in Leaside, a semi in Bloor West Village, or a condo in Yonge-Eglinton — eggshell on the walls is my default recommendation unless there's a specific reason to go higher or lower on the sheen scale. It looks good, it holds up to real life, and it doesn't show every imperfection in the wall surface the way higher sheens can.
Best for: Living rooms, dining rooms, adult bedrooms, home offices, any room where you want a balance of appearance and practicality.
Satin: For High-Traffic and High-Moisture Areas
Satin has noticeably more sheen than eggshell and a harder, more washable surface. In good lighting you can see the light reflecting off a satin wall — it gives the surface a slight glow. The trade-off is that satin shows surface imperfections more readily than eggshell; if your walls have texture, patches, or irregularities, satin will make them more visible.
I recommend satin in high-traffic areas where the walls take regular abuse: hallways, stairwells, kids' rooms, mudrooms, and laundry rooms. The added durability means the surface can handle actual scrubbing, which matters when there are children (or dogs) in the house.
Satin also works in bathrooms and kitchens, though I often use semi-gloss in those spaces. The higher humidity tolerance and easier cleaning of semi-gloss makes it worth the extra sheen in rooms with steam and cooking grease.
Best for: Kids' rooms, hallways, stairwells, mudrooms, bathrooms (acceptable, though semi-gloss is better), high-traffic areas generally.
Semi-Gloss and Gloss: Where They Actually Belong
Semi-gloss is the standard finish for all trim work — baseboards, door frames, window casing, crown moulding. It's durable, easy to clean, and the slight reflectivity gives trim an appropriate visual pop against the wall colour. On trim, semi-gloss is almost always the right call.
Doors — both interior and exterior — typically get semi-gloss or gloss depending on the style. A painted wood front door in gloss finish looks sharp and is easy to wipe down. Interior doors in semi-gloss match the trim and hold up to daily use.
Full gloss is used sparingly — on furniture painting, some cabinet work, or as a deliberate stylistic choice in specific situations. It shows every imperfection in the surface, so it requires a very well-prepared substrate and careful application to look intentional rather than rough.
Jay's Default Choices by Room Type
- Ceilings: Flat/matte, almost always. Ceiling paint is specifically formulated to be flat and to minimise sheen in overhead light.
- Master bedroom: Eggshell on walls, semi-gloss on trim.
- Kids' rooms: Satin on walls (it'll need cleaning), semi-gloss on trim.
- Living/dining room: Eggshell or flat depending on traffic level and client preference, semi-gloss on trim.
- Kitchen: Satin or semi-gloss on walls, semi-gloss on trim and cabinets if painting them.
- Bathroom: Semi-gloss on walls — moisture resistance matters here. Semi-gloss on trim.
- Hallways and stairwells: Satin on walls — takes the daily abuse of bags, hands, and furniture traffic. Semi-gloss on trim.
When I quote an interior job, I discuss finish choices with every client. It's a five-minute conversation that significantly affects how the finished rooms look and how long they stay looking that way.
