Homeowners spend weeks choosing a colour and about ninety seconds choosing a sheen. That is backwards. Colour is what you notice on day one; sheen is what you live with — how the wall handles light, how well it wipes clean, and how much of the surface underneath it reveals.
Interior walls: flat, matte, or eggshell
Flat and matte finishes scatter light, which is what makes them so forgiving. On an older wall with patched areas, minor waviness, or a skim coat that is not perfect, flat hides a great deal. The trade-off is cleanability — scrubbing a flat wall burnishes it and leaves a shiny patch.
Eggshell is the practical middle ground and what we use in most living spaces. It cleans reasonably, still hides moderate imperfection, and gives walls a soft depth that flat can look chalky next to.
Kitchens, bathrooms, and hallways: satin
Anywhere that sees moisture, grease, or hands on the wall wants satin. It wipes down properly and resists moisture far better than eggshell. It also shows more of the surface beneath, so prep matters more — which is precisely why we patch and sand more carefully in these rooms.
Trim, doors, and cabinetry: semi-gloss
Trim takes contact, so it needs a hard, washable film. Semi-gloss delivers that and gives the crisp edge definition that makes casing and baseboard read as intentional. Full gloss is available but unforgiving — every dent and filled nail hole reflects light differently.
Ceilings: flat, almost always
Ceilings get raking light from every fixture and window in the room, which magnifies any texture difference. Flat is what keeps that invisible. The exception is a bathroom ceiling, where moisture resistance justifies stepping up to a matte or eggshell rated for it.
Exteriors: the rules change
Outside, sheen is about durability and dirt more than appearance. Satin on siding gives a finish that sheds water and washes down without looking plasticky. Trim and doors go semi-gloss for the same reasons they do indoors, plus better resistance to sun and moisture.
One important note on vinyl siding: it must be coated with a vinyl-safe product. Standard paint in a darker colour absorbs more heat than the material was designed for, and the panels can warp permanently. Product selection here is not a preference — it is a requirement.
The part that matters more than any of this
Sheen choice is real, but prep is what determines whether a paint job looks good in five years. Patching, sanding, spot-priming bare material, and caulking joints before coating is roughly eighty percent of the result. Paint does not hide a poor surface — it highlights it under every angle of light in the room.
