How to choose sheen levels — flat, low sheen, satin and gloss

Sheen is the thing owners pick last and regret first. A south-facing Frankston living room painted in a crisp satin will look like a wet ice block in July. The same colour in a decent low sheen will recede and let the garden do the talking. Gloss on battered 1970s architraves will spotlight every dent. Flat on a hallway will die at the first schoolbag.

This is a specification guide for interiors, with a nod to exterior trims. Colour testing is a sibling art — see testing paint colours.

What the words mean on an Australian tin

Manufacturers are not perfectly consistent, but the ladder is:

• Flat / matt / ceiling: almost no reflectance. Hides plaster sins. Marks when cleaned.
• Low sheen / washable matt: the Australian wall default. A little light, a lot of wipe.
• Satin / semi-gloss: obvious light. Good on wet-area walls, doors, sometimes kitchens.
• Gloss: traditional woodwork and the odd statement door. Harsh on imperfect surfaces.

“Wash & Wear” style names describe a film toughness more than a sheen. Always check whether you have tinted a low sheen or a satin. A mis-tinted sheen is how a whole open-plan comes out slightly shiny on one wall because someone grabbed the wrong base.

Walls: default to low sheen, then make exceptions

Bedrooms, living rooms, dining rooms, rumpus: low sheen. It copes with Peninsula raking light off the bay, which is unkind to satin. It copes with rental inspections. It does not pretend to be a Venetian plaster.

Exceptions:

• Very poor plaster you are not paying to skim: a flatter wall finish is more merciful, at the cost of cleaning.
• Kids’ rooms and hallways: still low sheen, but a tougher washable line, not the cheapest contractor matt.
• Powder rooms: can take a little more sheen if you want wipeability and the plaster is good.

Feature walls in dark colours show sheen changes more than pale coastal greys. If you must go dark, keep the sheen modest unless you enjoy seeing every roller halt.

Ceilings stay flatter than walls

Ceiling white in a ceiling formulation is flat on purpose. Putting wall low sheen on a ceiling because you have leftover tint will flash. In bungalows with imperfect plaster, flat is a kindness. In a sharp new Mount Eliza box with raked plasterboard, you still want ceiling paint; the board is already perfect enough.

Wet areas and kitchens

Bathrooms want a wet-area film and usually a low sheen or satin you can wipe. Kitchens want the same on the walls that cop splatter, not necessarily on the whole open-plan. An open kitchen-living room can use low sheen throughout if the cooking wall is tiled. If the cooker sits against painted plasterboard, give that wall the tougher, slightly higher sheen and accept a faint change of plane. Better a honest change than a matte wall that cannot be cleaned. More in the bathroom wet-area guide and kitchen painting.

Trim, doors and the enamel question

Skirting, architraves, window sashes and doors traditionally sit a step glossier than walls. That extra sheen is washability and a crisp line. Water-based enamels have improved; they still need a decent primer over old oil gloss. If you paint new water-based enamel straight over un-sanded 1980s oil gloss, the sheen you chose will be on the floor in a year. See painting over oil-based enamel.

Full gloss on doors looks magnificent for a week on a perfectly filled surface. On a chewed family door it looks like a wet map of history. Semi-gloss is the Peninsula compromise.

Exterior sheens

Exterior walls are usually low sheen. Exterior trims can be a touch higher. Full gloss exteriors on weatherboards are a heritage look that shows every lap and every sanding skip; they also cop more UV stress on the binder. Coastal houses already fight UV. Do not add a glossy north wall unless you know why.

Light, sheen and the south room

South rooms on the Peninsula receive cool, indirect light. Higher sheens go greasy. Lower sheens go velvety. If a colour felt perfect on a north sample board, check it in the south room in the actual sheen. A satin sample can shift a grey toward blue. A flat sample can make the same grey look dusty.

Sheen is part of the colour. Specify both on the quote — product, colour code, and sheen — or you will get whichever tin was in the rack. That one extra word on the paperwork is cheaper than repainting a living room because it came out shiny.

Burnishing, the dark-colour problem

Dark low sheens show a polished patch where people touch the wall — light switches, hall corners, behind dining chairs. That is burnishing. A slightly tougher washable formulation helps. A mid colour helps more. If you must have a near-black interior wall in a family hall, accept that it is a furniture-like surface and will need a careful clean, not a scrub with the bathroom cream cleanser.

Mixing leftover sheens

The garage shelf is a graveyard of half-tins. Adding a bit of satin to a low sheen to “make it go further” creates a wall with a weather map of shine. Do not. If you are short, buy more of the same code and sheen. If the batch has shifted, turn a corner rather than blend in the middle of a plane.

Exterior trims versus interior trims

Exterior gloss takes UV and goes brittle faster. Interior gloss lives easier. Do not assume the same sheen name is the same product. Keep exterior trim in exterior enamel or exterior acrylic at the nominated sheen. The Weathershield versus All Weather piece is about systems; sheen is a field on the same specification.

A room-by-room cheat sheet

• Ceilings: flat ceiling paint.
• Bedrooms and living: low sheen.
• Halls: washable low sheen.
• Bathrooms and laundries: wet-area low sheen or satin.
• Kitchen splash wall: wipeable, maybe a step up in sheen.
• Doors and windows: water-based enamel, semi-gloss unless the joinery is perfect enough for gloss.
• Skirting: same as doors, or a fraction lower if you cannot stand the contrast.

Write it on the quote. Sheen is not a conversation you want to have after the roller is wet.
