Matt or silk emulsion for grey walls?
Updated: October 2026
You are standing in a hallway or bedroom with a grey colour in mind, but the finish will change the result almost as much as the shade. When choosing matt or silk emulsion, use the condition of the wall and the amount of cleaning it faces as your deciding factors: matt is more forgiving, while silk is generally easier to wipe but more revealing. Among the [12 grey wall paints in our main comparison](/hub/paints-and-varnishes/wall-paint-grey), the clearest like-for-like example is Johnstone’s Manhattan Grey in 5-litre matt and silk tins, both listed at £28.65. The price does not decide it; your room does.

What the sheen changes on a grey wall
Matt scatters light rather than throwing back an obvious reflection. On a wall with shallow dents, uneven filler or old roller texture, that flatter appearance tends to make the defects less noticeable.
Silk reflects more light, so it can make a narrow hall feel brighter and may be more practical where fingerprints need wiping away. The trade-off is that raking light from a window or lamp can pick out every ridge. Dulux describes matt as a finish that helps hide imperfections and silk as a wipeable mid-sheen that shows lumps more readily.
The two 5-litre Manhattan Grey listings make the choice unusually clear. The matt and silk tins were each £28.65, or £5.73 per litre, when assessed on amazon.co.uk. The matt had 4.5 stars from 1,670 reviews, while the silk had 4.6 from 1,842. Neither listing supplies an EN 13300 wet-scrub class.
Choose matt when the plaster is tired
Matt is the safer choice for a dry bedroom or living room if the plaster is sound but visibly imperfect. Filling and sanding still matter, yet the flat surface is less likely than silk to turn a small repair into a shiny outline.
The 5-litre Manhattan Grey matt claims 65 m² per tin. Johnstone’s Steel Smoke matt is explicitly marked as not water resistant, so it should not be presented as a hard-wearing hallway paint merely because other matt emulsions can be durable. Compare the broader trade-offs in the grey wall paint buying guide before choosing a tin size or colour depth.
Choose silk or soft sheen where hands touch the wall
Silk makes more sense in a busy hallway when wiping marks is more important than disguising texture, provided you have filled and sanded the wall carefully. The Manhattan Grey silk listing claims 12 m² per litre, has a one-hour listed dry time and was the best-value pick in the main comparison.
Soft sheen sits between the visual flatness of matt and the stronger reflection of silk. The Johnstone’s Manhattan Grey soft-sheen 5-litre tin was our top pick, based on a 4.7 rating from 257 reviews and a competitive £29.08 shelf price. It is still not waterproof. A steamy room is a different decision. The dedicated Manhattan Grey bathroom paint is the only product in this set with a waterproof flag set to true, so use the grey bathroom paint guide for that scenario.
The recommendation, with a condition
Choose matt for a dry bedroom or living room when the wall has small imperfections and cleaning is occasional. Choose silk for a properly prepared hallway or other high-contact dry area when you accept more reflection in return for a surface intended to be easier to wipe.
For a smooth family hallway, soft sheen is the more balanced recommendation because it offers some cleaning practicality without looking as reflective as silk. Do not patch a silk wall with matt and expect the repair to disappear. Even if the colour name matches, the different reflection will remain visible from an angle.

Common questions
Will silk make a dented wall look worse in grey?
Usually, yes. Silk reflects more light than matt, so dents, filler edges and roller ridges can cast highlights and shadows, particularly beside a window. Grey does not cause the defect, but a mid-tone colour can make changes in reflection easy to see. Fill, sand and inspect the wall with side lighting before choosing silk.
Is matt emulsion impossible to wipe?
No, but “matt” alone does not tell you how well a paint withstands repeated cleaning. Some durable matt products are formulated for wiping, while an ordinary matt may polish up or lose colour when rubbed. Check the manufacturer’s cleaning guidance or a stated scrub classification rather than assuming every matt behaves alike.
The 5-litre matt and silk tins cost the same. Which should I buy?
Buy matt if the wall is imperfect and the room has low traffic. Buy silk if the wall is smooth and fingerprints or scuffs are a regular problem. Both Manhattan Grey 5-litre listings were £28.65 when assessed, so there was no saving to compensate for choosing the wrong sheen.
Where does soft sheen sit?
Soft sheen is the middle option: more reflective and potentially easier to wipe than ordinary matt, but less visually glossy than silk. The Manhattan Grey soft-sheen tin was the top pick in this comparison set, although it remains unsuitable as proof of a waterproof bathroom coating and will still expose some wall texture.
Can I use silk in a bathroom instead of bathroom paint?
Do not rely on the word “silk” alone. The Manhattan Grey silk listing says water repellent but not waterproof, whereas the dedicated bathroom version has a waterproof flag set to true. Ventilation and treatment of any underlying damp still matter, and persistent mould or moisture needs its cause addressed before repainting.
Does silk flash if I roll back into a drying edge?
It can. Overworking an area that has started to dry may leave a different texture or sheen, which becomes visible in side light. Keep a wet edge, work in manageable sections and follow the tin’s recoat instructions. If a patch has already dried unevenly, recoating the full wall is usually less conspicuous than spot correction.
