Use flat for ceilings, eggshell for bedrooms and living rooms, satin for kitchens and kids' rooms, and semi-gloss for bathrooms, trim, and doors. The higher the sheen, the more durable and washable the finish - but also the more it highlights wall imperfections.
Paint colour gets most of the attention, but finish - also called sheen - is equally important and frequently misunderstood. Pick the wrong finish and you'll either be scrubbing marks off flat paint that won't come clean, or staring at shiny walls that highlight every bump and roller mark. Here's exactly what to use where, and why, based on what our Toronto painting crews recommend after years of residential and commercial projects across the GTA.
Paint finishes run from completely matte to highly reflective. The sheen level affects four things: durability, cleanability, how much light the surface reflects, and how much it shows wall imperfections. Higher sheen = more durable and washable, but also more reflective and more revealing of surface flaws.
| Finish | Sheen Level | Washability | Best For |
|---|---|---|---|
| Flat / Matte | None | Poor | Ceilings, low-traffic formal rooms |
| Eggshell | Very low | Fair | Living rooms, bedrooms, dining rooms |
| Satin | Medium-low | Good | Kitchens, kids' rooms, hallways |
| Semi-Gloss | Medium-high | Excellent | Trim, doors, bathrooms, cabinets |
| Gloss / High-Gloss | High | Excellent | Accent furniture, exterior doors, specific trim |
Ceilings should almost always be flat or matte. Sheen on a ceiling catches and amplifies every imperfection - roller marks, texture variation, old repairs - and sends light bouncing in unflattering directions. Flat paint diffuses light evenly and makes ceilings look higher and cleaner.
Most major paint manufacturers offer a dedicated "ceiling white" product in flat finish. Benjamin Moore Ceiling White and Sherwin-Williams Ceiling Bright White are the most common across GTA painter specs. If you're doing an open-plan space where the ceiling connects to high walls, keep the ceiling strictly flat even if the walls are eggshell.
Eggshell is the standard choice for Toronto living rooms. It has just enough sheen to feel rich and saturated without being reflective, and it holds up reasonably well to light cleaning - wiping down a scuff or fingerprint is possible without leaving a shiny patch. Unlike flat, eggshell won't lose its finish when you touch it up.
The exception is formal living rooms that see low foot traffic and are never exposed to moisture or kids - flat or matte can work beautifully there and gives walls a sophisticated, gallery-like quality.
Bedrooms are low-traffic, low-moisture, and rarely need intensive cleaning. Eggshell is still our default recommendation because it's more touch-up-friendly than flat, but flat is a legitimate choice in adult bedrooms where you want that deep, luxurious colour saturation - especially with darker accent colours like navy or forest green, where flat finish makes the colour look exceptionally rich.
Kids' bedrooms are the exception - use satin in any bedroom where kids will leave handprints, draw on walls, or throw things. The extra durability is worth the slight sheen.
Kitchens generate grease, steam, and splatter, and walls need to be wipeable. Satin is the right answer - it's durable enough to clean properly, not so shiny that it looks like a bathroom. Kitchen cabinets are a separate question - they typically get semi-gloss or gloss for maximum durability and cleanability.
If your kitchen flows open to your dining or living room, match the kitchen wall finish to the connected space (satin throughout) rather than creating a visible sheen change at an arbitrary point.
Bathrooms are the most finish-critical room in the house. Flat or eggshell in a bathroom will absorb moisture, encourage mildew growth, and be impossible to clean. Minimum finish for a bathroom wall is satin. Semi-gloss is better if the bathroom sees high use, has poor ventilation, or has walls close to the shower or tub.
Make sure you're also using a paint with mildew-resistant additives in bathrooms - most major manufacturers offer this as a product line. Benjamin Moore Aura Bath & Spa and Sherwin-Williams Emerald Interior with mold and mildew resistance are two products our crews use frequently in Toronto bathroom repaints.
Hallways take more abuse than any other surface in the house. Every person who walks through brushes a shoulder against the wall, touches the paint with keys, and leaves marks at chair-rail height. Satin is the minimum in hallways - some clients prefer semi-gloss in particularly high-traffic halls, like main entrance corridors or children's play areas. The extra sheen is worth the durability trade-off.
Semi-gloss is the industry standard for trim, doors, baseboards, and window casings, and for good reason. Trim takes direct impact, scuffs, and kicks constantly. The higher durability of semi-gloss holds up far better than any lower sheen finish, and the slightly glossy look creates a visual separation from the walls that defines the architecture. For interior doors specifically, some clients prefer a full gloss for a lacquer-like quality - that's a stylistic choice that works in contemporary interiors.
This is the single most common mistake we correct on repaint jobs in the GTA. Flat paint in high-moisture rooms absorbs humidity and cannot be cleaned without rubbing the finish off. If you're repainting over flat bathroom walls, you'll need to properly prime before applying a moisture-appropriate finish.
Some homeowners choose semi-gloss throughout the house thinking it's the most durable option. It is more durable, but high-sheen paint on bedroom and living room walls highlights every imperfection - roller marks, patches, bumps in drywall - and creates a visual quality that reads more institutional than residential. Match the sheen to the room's requirements.
If your living room has one accent wall in a different colour than the other walls, both walls should have the same finish. Different sheens on adjacent walls create visible light-reflection differences that look unintentional and cheap. This also applies when touching up - if you touch up a satin wall with leftover flat paint, you'll see a matte patch even if the colour matches exactly.
If you're painting over semi-gloss or gloss walls with eggshell or flat, you must lightly sand the surface first. New paint won't properly adhere to high-gloss without a mechanical bond. Our prep process always includes sanding slick surfaces - it's one of the key reasons professional results outlast DIY repaints.
Satin or semi-gloss. Both resist moisture and wipe clean. Semi-gloss is the more durable choice for shower-adjacent walls; satin works well for main bathroom walls where you want less shine.
Eggshell for most Toronto living rooms - very low sheen, wipeable. Flat only for low-traffic formal rooms where cleanability isn't a concern.
Satin has soft, velvety sheen - reflective but not shiny. Semi-gloss has noticeably higher sheen and is more durable and moisture-resistant. Use satin on walls in high-traffic rooms, semi-gloss on trim and in bathrooms.
Eggshell everywhere is a common compromise, but bathrooms really need satin or semi-gloss for moisture resistance, and ceilings almost always look best in flat. Match finish to function.
