Types of Paint: Emulsion, Eggshell, Satin & Gloss

Walk into any UK decorating merchant and you will find dozens of finish names, matt, flat matt, soft sheen, eggshell, satin, semi-gloss, full gloss. The terminology can seem arbitrary, but each finish sits on a straightforward sheen scale and has properties that make it genuinely better suited to certain surfaces and rooms. Getting the right paint type is the difference between a finish that wipes clean and one that marks at the first touch.

The key variable is sheen level, how much light the dried film reflects. Higher sheen means more durability, better washability, and greater moisture resistance. Lower sheen hides surface imperfections but is harder to clean. The practical decision is always a trade-off between aesthetics and performance.

Paint Types at a Glance

The sheen percentages are approximate: manufacturers measure and name sheen levels differently, so compare products within one brand’s range.

Emulsion Paint

Emulsion is the broad category covering most water-based wall and ceiling paints. “Emulsion” refers to the binder (acrylic or vinyl polymer suspended in water) rather than a specific sheen, so you can buy matt emulsion, soft sheen emulsion, or even eggshell emulsion.

Matt emulsion is the default for walls and ceilings in living rooms and bedrooms. It absorbs light rather than reflecting it, making it forgiving of minor plaster imperfections, uneven textures, and ageing surfaces. The trade-off is that marks and scuffs are difficult to wash off without burnishing or removing paint. Standard vinyl matt is not suitable for kitchens or bathrooms.

Vinyl silk or soft sheen emulsion sits just above matt in sheen. It is the standard choice for hallways, stairwells, and children’s bedrooms where walls take more knocks. It wipes down reasonably well and is durable enough for moderate traffic without looking overly shiny.

Kitchen and bathroom emulsion is a specialist product with anti-mould additives and enhanced moisture resistance. It typically has a soft sheen or eggshell finish to aid cleaning. It is worth paying for in rooms with steam and splashes: a standard matt emulsion can blister and grow mould in a poorly ventilated bathroom. Dulux Trade, for example, recommends its Diamond Eggshell rather than its soft sheen emulsion where condensation is a problem in kitchens and bathrooms.¹

Eggshell Paint

Eggshell gives a low-lustre finish, slightly more sheen than a soft sheen emulsion but far less than satin or gloss. The name comes from the subtle texture of an egg’s shell. It is increasingly popular for walls in kitchens and dining rooms where people want a wipe-clean surface without the hard shine of gloss.

Eggshell is also the standard choice for interior woodwork in period and traditional-style homes where a high-gloss finish would look out of place. Applied to primed bare wood or over a sanding sealer, it gives a smooth, slightly satiny result that shows off mouldings well.

Water-based eggshell (acrylic eggshell) has largely replaced oil-based versions. It is much quicker to recoat: Dulux Trade Diamond Eggshell, a water-based eggshell, is recoatable after 4–6 hours.² The solvent-based Dulux Trade Eggshell needs 16–24 hours before it can be recoated.³ Water-based eggshell also has lower VOCs, stays white without yellowing, and is easier to clean up. Oil-based eggshell retains an edge for exterior woodwork and for surfaces that need maximum hardness, but is rarely used indoors in new projects.

Satin Paint

Satin sits between eggshell and gloss, a medium sheen that is highly durable, very washable, and suitable for surfaces that take daily use. In the UK, satin is the go-to finish for:

• Interior doors
• Skirting boards and architraves
• Kitchen unit fronts
• Radiators (use a radiator-specific satin with heat-resistant pigments)
• Bathroom walls (moisture-resistant formulations)

Water-based satin (often sold as “satinwood” on UK tins) is the dominant product on shelves. Application technique matters more with satin than with matt, brush marks and roller stipple are visible in raking light, so working quickly with a good synthetic brush or foam roller is essential.

Gloss Paint

Full gloss is the most reflective interior finish and the toughest against wear. Traditionally the standard for all interior woodwork, it has been largely replaced by eggshell and satin in modern interiors. However, gloss remains the correct choice for:

• Exterior woodwork, fascias, soffits, window frames, gates
• Exterior metal, railings, gates, drainpipes (with appropriate metal primer)
• Front doors, particularly in heritage colours on period properties
• Radiators where you want a traditional look (use radiator enamel gloss)

Water-based gloss has improved considerably but still does not quite match the flow and levelling of oil-based gloss, which is why decorators often use oil-based products on front doors where a mirror-smooth finish is expected. Oil-based gloss yellows over time, particularly in areas with low light, avoid it on white or off-white woodwork in rooms with limited sunlight.

Water-Based vs Oil-Based Paint

Most modern UK decorating uses water-based products. Here is how they compare:

Dulux Trade’s solvent-based High Gloss, for example, is dry in 4–6 hours but cannot be recoated for 16–24 hours.⁴

In the UK, VOC (volatile organic compound) content in decorative paints is capped by the Volatile Organic Compounds in Paints, Varnishes and Vehicle Refinishing Products Regulations 2012, which implemented EU Directive 2004/42/EC. Trim paint for wood and metal, which covers most eggshell, satin and gloss, is limited to 130 g/l if water-based and 300 g/l if solvent-based.⁵ A product over the limit for its category cannot legally be placed on the market, and its label must state the category limit and the product’s maximum VOC content in grams per litre.⁶ Most water-based paints sit comfortably within their limits.

Specialist Paints Worth Knowing

Masonry paint is formulated for external brick, render, and stone. It contains fillers that bridge fine cracks and is highly breathable to allow moisture to escape from the wall. Standard interior emulsion will flake and fail quickly on exterior masonry.

Floor paint contains hardening agents and abrasion-resistant resins. Do not paint concrete or tile floors with wall paint: it will soon wear through and peel. Purpose-made floor paint (typically epoxy or polyurethane-based) lasts several years with proper surface preparation.

Primer is not a finish coat, it seals the substrate and improves adhesion. Bare plaster needs a mist coat of emulsion thinned with water (Dulux Trade suggests up to 1 part water to 5 parts paint for its Vinyl Matt on new or bare surfaces) or a dedicated plaster primer before topcoats.⁷ Bare wood needs wood primer. MDF needs MDF primer to seal the porous edges. Skipping primer is a common cause of paint failure.

Choosing the Right Paint: Quick Decision Guide

• Ceilings, flat matt or contract matt emulsion. Sheen on ceilings catches every imperfection.
• Living room / bedroom walls, vinyl matt or soft sheen. Matt for older, imperfect plaster; soft sheen if you have young children or pets.
• Hallway walls, soft sheen or eggshell emulsion for durability.
• Kitchen walls, kitchen emulsion (soft sheen or eggshell) with anti-mould additive.
• Bathroom walls, bathroom emulsion or eggshell with moisture resistance.
• Interior woodwork (period homes), water-based eggshell.
• Interior woodwork (modern / high traffic), water-based satin.
• Exterior woodwork, gloss or specialist exterior satin; oil-based for front doors.
• Radiators, radiator enamel in satin or gloss.

Understanding the sheen scale and the water-based versus oil-based distinction will take you a long way. When in doubt, choose a higher-quality branded product in the correct category rather than an economy product in the wrong one, coverage, durability, and ease of application improve noticeably with quality.
