Paint Finishes Explained: Matt, Eggshell, Satin and Gloss

Two tins of the same colour can produce two very different rooms. One wall looks soft and chalky, the other crisp and almost reflective, and the difference is entirely down to sheen: how much light the dried paint film bounces straight back at you. Sheen affects how deep a colour reads, how easily marks wipe off, how long the surface lasts and, crucially, how much of the plaster or woodwork underneath it reveals. Choosing the right finish is just as important as choosing the colour, and it is one of the easiest decisions to get wrong.

This guide explains what each finish actually is, where it performs best, the trade-off between durability and forgiveness, and how preparation and primers change the outcome.

What sheen actually measures

Manufacturers measure sheen with a gloss meter that shines a beam of light at a painted panel and records how much is reflected at the mirror angle. The result is given in gloss units (GU), usually measured at 60° for most finishes and at 85° for very flat ones. The lower the number, the more the surface scatters light instead of reflecting it.

The physical reason is texture at a microscopic level. Flat paints contain more pigment and extender relative to binder, which leaves a slightly rough surface that scatters light in all directions. Glossy paints contain more binder, so the dried film is smoother and behaves more like a mirror. That same difference explains durability: binder is what holds the film together, so a resin-rich gloss resists scrubbing and moisture better than a pigment-rich flat matt.

Names on tins are not standardised. One brand's "eggshell" can be shinier than another's "satin", and in the UK "eggshell" is often sold as a low-sheen finish for woodwork rather than walls. When it matters, check the technical data sheet for the gloss level, or paint a sample board and look at it in your own light.

Treat these ranges as typical rather than exact; individual products vary.

The core trade-off: durability versus forgiveness

Every finish sits on a sliding scale. Move towards gloss and you gain toughness, moisture resistance and easy cleaning. Move towards matt and you gain a softer look and far better concealment of dents, filler patches and uneven plaster. No single finish wins on both counts, so the right choice depends on two questions: how much abuse will this surface take, and how good is the surface underneath?

A flawless, newly skimmed wall in a hallway can carry satin happily. An old lath-and-plaster wall with gentle undulations will look much better in matt, even in a busy area, because a shiny finish would turn every ripple into a visible highlight. Modern "durable matt" or "scrubbable matt" emulsions narrow the gap considerably: they use tougher binders to give a low sheen with good stain and scrub resistance, and for many homes they are now the default wall paint.

Reading the scrub rating

In Europe, wall paints are often classified under EN 13300 for wet scrub resistance, from Class 1 (most resistant) to Class 5 (least). The test measures how much of the film is worn away after repeated scrubbing. Class 1 and 2 paints can be wiped regularly without losing colour or developing shiny patches; Class 3 copes with occasional gentle cleaning; Classes 4 and 5 are best kept for ceilings and surfaces nobody touches. This rating is a more reliable guide to how a wall will cope with daily life than sheen alone.

Each finish in detail

Flat and matt

Flat finishes give the richest, most even colour because there is no glare to wash it out. Dark shades in particular look deeper and more velvety in matt. They are the best at hiding surface flaws, which is why ceilings are almost always painted flat: daylight from windows travels across a ceiling at a shallow angle and would expose every joint and ripple in a sheen finish.

The weakness of traditional flat matt is that rubbing can "burnish" it, leaving shiny patches where hands, chair backs or cleaning cloths have polished the surface. Marks can also be hard to remove without lifting paint. Use standard flat matt where walls are rarely touched, and choose a durable matt where people brush past.

Eggshell

Eggshell has a subtle lustre, roughly like the shell it is named after. On walls it is a sensible compromise for hallways, stairwells, playrooms and home offices: tough enough to wipe, soft enough not to emphasise minor imperfections. In the UK, many brands sell eggshell mainly for interior woodwork and furniture, where it gives a modern, low-sheen alternative to traditional gloss on skirting, doors and painted cabinets.

Satin and satinwood

Satin is a step shinier and noticeably more cleanable. It is a common choice for kitchens and bathrooms because it resists moisture and grease better than matt, and for woodwork where a little sheen helps define edges and mouldings. Expect it to show roller marks, brush laps and filler patches if the surface is not well prepared, and apply it carefully with a good-quality roller or brush, keeping a wet edge.

Semi-gloss and gloss

These finishes are the toughest and most moisture-resistant. They are ideal for surfaces that are handled constantly: door frames, banisters, window sills, kitchen cabinet doors and front doors. A high-gloss lacquered look can also be a deliberate design statement, for example on a dark-painted ceiling in a small room or a single piece of furniture.

The catch is unforgiving reflection. Gloss reveals brush strokes, dust caught in the wet film, dents and any ridges left by sanding. It needs meticulous preparation, thin coats and a clean environment. Traditional solvent-based glosses can yellow over time, particularly in rooms with little daylight; modern water-based alternatives stay whiter but can feel slightly less glassy.

Which finish to use, room by room

Use this as a starting point and then adjust for the condition of your surfaces and how your household lives.

• Living rooms and bedrooms: matt or durable matt on walls for depth of colour and a calm look; eggshell or satin on woodwork.
• Hallways and stairs: durable matt or eggshell on walls, because bags, coats and hands make constant contact. Consider a tougher finish below dado height if you have one.
• Kitchens: a kitchen-specific matt or satin that resists grease and steam. Satin or semi-gloss on cabinets if you are painting them.
• Bathrooms: a moisture-resistant bathroom formulation, usually in matt or satin. The formulation matters more than sheen here, and good ventilation matters most of all.
• Children's rooms: scrubbable matt (Class 1 or 2) on walls so crayon and sticky fingers can be wiped away without leaving shiny patches.
• Ceilings: flat or standard matt, ideally a dedicated ceiling paint with low spatter.
• Doors, skirting and frames: eggshell for a contemporary, low-sheen look; satin for a balance of durability and subtlety; gloss for a traditional finish or high-wear front doors.

Rooms with a lot of daylight, or a single strong window that rakes light along a wall, are where sheen differences become most obvious. If you are unsure, paint two large sample boards in the same colour but different finishes and view them at the wall at different times of day.

How sheen changes colour

The same colour looks slightly lighter and cooler in a higher sheen, because the surface reflects more light, including the colour of the sky or the room around it. Matt finishes look a touch darker and more saturated. This matters when you have tested a colour in one finish and intend to buy another; always sample the actual product you will use. If you are working through a wider scheme, the guidance in our article on choosing a colour palette for your home pairs well with this one, and for neutrals in particular see how to choose white paint.

A popular contemporary trick is "colour drenching" or tone-on-tone: painting walls, woodwork and sometimes the ceiling in one colour but varying the sheen, for example matt walls with eggshell skirting and doors. The colour stays consistent while the change in reflection subtly defines the architecture.

Preparation and primers: where finishes succeed or fail

Most disappointing results are preparation problems, not paint problems. The higher the sheen, the more preparation matters. A sensible sequence looks like this:

1. Clean. Wash walls and woodwork with a mild detergent or sugar soap, then rinse with clean water. Grease and residue stop paint from bonding and can cause cratering.
2. Repair. Fill holes and cracks, let the filler dry fully, and sand it flush. For satin and gloss, check repairs with a torch held flat against the wall; the raking light shows ridges the eye otherwise misses.
3. Key the surface. Lightly sand existing gloss or satin so the new coat can grip. Remove dust with a vacuum and a slightly damp cloth.
4. Prime where needed. Use the right primer for the substrate (see below).
5. Apply thin, even coats. Two thinner coats give a better, tougher film than one heavy coat, which can sag, take longer to cure and show lap marks.
6. Respect drying and curing times. Paint may be touch-dry in an hour but can take two to four weeks to reach full hardness. Wash gently, if at all, during that period.

Choosing a primer

• New plaster: once fully dry (pale and uniform in colour, which can take several weeks), apply a mist coat of diluted matt emulsion or a dedicated plaster primer. Undiluted vinyl paint on fresh plaster can sit on the surface and peel.
• Bare wood: a wood primer, then an undercoat matched to the topcoat. Seal knots with knotting solution first so resin does not bleed through as yellow-brown stains.
• Stains: water marks, smoke and marker pen need a stain-blocking primer, or they will reappear through new emulsion.
• Glossy or tricky surfaces: tiles, laminate and old gloss benefit from a bonding or adhesion primer after degreasing.
• Big colour changes: going from dark to light, a tinted primer or an extra coat saves effort and paint. Our guide to how much paint you need explains how to budget for that.

Common mistakes

• Choosing sheen for durability on a poor wall. Satin over bumpy plaster looks worse than matt, however easy it is to wipe. Fix the surface or choose a durable matt.
• Mixing finishes on one wall. Touching up a satin wall with matt, or the other way round, leaves visible patches. Keep a labelled tin of each finish used.
• Trusting the name on the tin. Eggshell and satin vary widely between brands. Compare gloss levels or sample boards.
• Skipping the mist coat on new plaster. Poor adhesion here can lead to peeling that only shows weeks later.
• Over-brushing gloss. Gloss levels as it dries; working it too long drags the brush through partially set paint and leaves marks. Lay it on, smooth it once, and leave it.
• Cleaning too soon. Scrubbing a fresh matt wall in the first week can polish it into shiny patches.
• Ignoring the light. A finish that looks lovely in the shop can glare in a south-facing room or under a low pendant. Test in place.

Quick checklist before you buy

• Have you checked the surface with a torch held flat against it? The worse the surface, the lower the sheen.
• How often will the surface be touched or cleaned? Busy areas need a scrub rating of Class 1 or 2 or a higher sheen.
• Is the room humid? Choose a kitchen or bathroom formulation, and make sure ventilation is adequate.
• Have you sampled the exact product, in the exact finish, on the actual wall, in morning and evening light?
• Do you have the right primer for each surface: mist coat, wood primer, stain blocker or bonding primer?
• Have you bought enough from the same batch to finish every wall, plus a little for touch-ups?
• Have you noted the colour, finish and batch number somewhere you will find it in two years' time?

Get the finish right and a room looks considered rather than simply painted: colours sit evenly, woodwork reads crisply, and surfaces stay looking fresh for years rather than months.

Frequently asked questions

What is the most hard-wearing paint finish for walls?

Higher sheens are generally tougher and easier to wipe, so satin or a scrubbable matt is the usual choice for busy walls. Look at the scrub-resistance rating on the tin (Class 1 or 2 under EN 13300 in Europe) rather than relying on sheen alone, because modern durable matts can outperform cheap silks.

Can I paint a gloss finish over matt, or matt over gloss?

You can paint gloss over a sound matt surface after cleaning and light sanding. Going from gloss to matt needs more care: degrease, sand the shine off (or use a bonding primer) so the new coat can grip, otherwise it may peel or scratch off easily.

Why does my wall look patchy after touching up?

Touch-ups show because the new paint sits at a slightly different sheen and thickness from the cured original, especially on satin and gloss. Feather the edges with a nearly dry roller, or repaint the whole wall from corner to corner for an invisible result.

Is eggshell the same as satin?

Not exactly. Naming varies between brands and countries, but eggshell usually sits just above matt with a soft, low sheen, while satin is a step higher and slightly more reflective. Always compare the gloss level or a painted sample rather than the name on the label.

What finish should I use on a ceiling?

Flat or standard matt is the norm for ceilings. Light from windows rakes across ceilings at a low angle, which exaggerates every ripple and joint, and a matt finish scatters that light so imperfections are much less visible.
