Dulux Trade Diamond Paint is formulated to be up to 50 times more durable than standard trade emulsions, built for interiors where standard paint wouldn't hold up. Both Diamond Matt and Diamond Eggshell carry a Class 1 scrub rating (ISO 11998) and are tested to withstand 10,000 scrub cycles without dulling.Â
The range's unique Stain Repellent Technology actively repels unwanted stains and everyday splashes from the paint film, preventing stains from soaking in. This means walls stay looking new through multiple maintenance cycles. Additional benefits include:Â
-
Quick-drying water-based formulas help keep projects on schedule
-
Low-odour, low-VOC formulations with minimal indoor emissions, making it suitable for occupied interiors where downtime isn't an option
-
Consistent colour across finishes, allowing you to specify one shade and match it seamlessly from walls to trim
-
Mixed to order in-house at The Paint Shed, to any Dulux, BS or RAL reference
Explore our range of Dulux Trade Diamond paints below.
Dulux Trade Diamond Matt
Best for: Any interior surface where a soft, flat finish suits the brief, including large wall areas, corridors, offices and communal stairwells.
A tough and cleanable emulsion built for busy areas, Dulux Trade Diamond Matt is the flat finish of the Diamond range and the highest-coverage product in the line at up to 16m²/L.Â
Its non-reflective finish delivers great opacity and a uniform matt finish across interior walls and ceilings, disguising minor surface imperfections that a higher-sheen paint would highlight. Recoatable in 4–6 hours, this durable paint is available in Pure Brilliant White, Magnolia or mixed to any shade via our in-house colour-matching service.
Dulux Trade Sterishield Diamond Matt
Best for: Hospitals, clinics, food preparation areas, commercial kitchens, nurseries, schools, veterinary practices and any interior spaces where a hygiene-critical specification applies.
Dulux Trade Sterishield Diamond Matt features the same Diamond Matt base formulation but adds an in-film bactericide that inhibits the growth of bacteria on the paint surface, including MRSA and E. coli.
Plus, unlike many water-based anti-bacterial paints, Sterishield is formulated to resist the off-yellow tint that hygiene paints are often prone to developing over time. This antibacterial paint is available in Pure Brilliant White or mixed to any shade.
Dulux Trade Diamond Eggshell
Best for: Kitchens, bathrooms and other high-humidity interiors, plus communal corridors, reception areas and high-traffic walls where you want the subtle sheen of eggshell without the usual durability trade-off.
Eggshell finishes typically trade durability for aesthetics, but Dulux Trade Diamond Eggshell closes that gap. This cleanable emulsion takes scuffs, stains and regular scrubbing in its stride without dulling, making it a stronger option than standard eggshell for any wall that sees consistent handling. Available in Pure Brilliant White, Magnolia or any matched shade.
Dulux Trade Diamond Satinwood
Best for: Doors, skirting, architrave, window frames and interior metal work. Not for plasterboard or woodchip; use Diamond Matt or Eggshell for those.
Dulux Trade Diamond Satinwood is formulated for interior wood and metal, not wall plaster. Delivering coverage of up to 12m²/L, it is self-priming on previously painted surfaces in good condition, with a primer recommended on bare wood and metal. The Pure Brilliant White option is colour-stable, so it won't yellow over time. It is also formulated to resist stains and grease, making it useful for commercial kitchens and cooking areas.

FAQs
It depends on the surface:
-
New or bare surfaces (such as fresh plaster): Apply a mist coat (a thinned first coat) of Dulux Trade Diamond or Dulux Trade Supermatt to seal bare surfaces before your first full coat.
-
Bare wood or metal: Use Dulux Trade Aqua Uniprimer for strong adhesion and added resistance to moisture and stains. Particularly relevant if you're applying Diamond Satinwood.
-
Previously painted walls in sound condition: No primer needed. Spot-prime any patches of bare substrate and ensure the surface is clean and dry.
-
Covering a contrasting existing colour: A tinted matt base coat underneath improves opacity and reduces the number of topcoats you'll need.
The two finishes sit at different sheen levels and perform best in different environments.Â
-
Diamond Matt has a low sheen (~7%), giving a soft, non-reflective finish that disguises minor surface imperfections. This makes it ideal for halls, stairwells, corridors and large wall areas.Â
-
Diamond Eggshell has a higher sheen (~20%), delivering a subtle gloss that's easier to wipe clean and more resistant to moisture. It's the Dulux-recommended choice for kitchens, bathrooms and any interior walls or woodwork in humid environments.
The normal finishing process requires two coats on a correctly prepared, primed surface. You may need an additional coat when covering a significantly darker or more saturated colour, or when painting onto bare plaster or new substrates.Â
Thanks to the quick-drying, water-based formula, second coats can typically be applied 4–6 hours after the first. Always allow each coat to dry fully before recoating, and check the product Technical Data Sheet (TDS) for the exact recoat window.
