Which paint type should I choose (1K, 2K, 2K Air-Dry)?

1K is ready to use and suits lighter-duty jobs and touch-ups. 2K contains a built-in hardener for higher chemical and abrasion resistance on demanding surfaces. 2K Air-Dry provides 2K performance with a non-isocyanate hardener for easier handling. Note: our 2K aerosols are supplied as Acrylic Enamel only.

Do I need a primer, and which one is right?

Preparation is essential: clean, degrease and key the surface. Use the correct primer for the substrate: plastic adhesion primers for plastics, glass or fibreglass primers for those materials, and metal/etch primers for metals. Using the right primer improves adhesion and longevity.

How long does it take to dry, and when can I recoat?

For 1K, apply light passes and recoat after around 10–15 minutes; typical cure is about 30 minutes depending on conditions. For 2K, recoat after around 20–30 minutes, touch-dry is about 40 minutes, and full cure is usually 24–48 hours. Temperature and humidity affect all drying and curing times.

How much will I need (coverage & coats)?

A 400 ml aerosol typically covers up to approximately 2 m² per coat on smooth, primed surfaces. Most jobs need 2–4 coats depending on the colour, surface profile and the shade being covered.

Any tips for a smooth, professional finish?

Shake the can for 2–3 minutes and during use. Spray 15–25 cm from the surface in light, even passes with slight overlap. Keep the can upright and clear the nozzle with a short burst after use. Use adjustable fan patterns to suit the area and reduce overspray.

Can I spray indoors, and what safety should I consider?

Only spray indoors with excellent ventilation and appropriate PPE such as a respirator, gloves and eye protection. Protect surrounding areas from overspray. Refer to product data sheets for detailed safety and handling guidance.

Trade Application Notes

NCS S 6020-R90B is part of our NCS (Natural Colour System) Paint Colour Chart. Each order is mixed fresh using Lechler binders and colourants, so follow on orders are designed to sit neatly alongside earlier work for touch ins, snagging and small repairs.

Formats: 400 ml aerosols in 1K (ready to use), 2K (with integrated hardener) or 2K Air Dry, plus 1 litre tins, touch up pots and pens for fine detail and small areas.
Finishes: Matt, satin, semi gloss and full gloss options so you can match existing schemes, client specification or a particular maintenance schedule.
Surface preparation: For the best result we suggest degreasing, lightly abrading to a uniform key and carefully removing dust. Please choose a suitable primer for the substrate and environment.
Masking and protection: It is a good idea to protect nearby glazing, brickwork, signage and floor surfaces. Simple masking and sheeting can greatly reduce clean up time on busy sites.
Application control: The vari nozzle cap can be set to a wider or narrower fan pattern to suit the job. This helps with gentle edge control and can reduce unwanted overspray.
Overspray awareness: On external work it helps to think about wind direction and people passing close by. Temporary screens and a clear working zone can make application more relaxed.
Weather window: Choose a dry, clean surface and avoid conditions where rain or condensation are likely. Please follow the temperature and humidity guidance in the product data sheet.
Recoat and curing: Several lighter coats with the recommended flash off time usually give a smoother, more even finish. Allow time for full cure before any heavy cleaning or handling.
2K products: 2K materials are for professional use and are best applied with suitable PPE and good ventilation. Mix carefully, respect pot life and dispose of any waste responsibly.
Equipment: Aerosol cans will usually perform better if kept at room temperature and shaken well before use. Tins can be applied using compliant spray equipment or with a fine foam roller and brush for edges.
Coverage and appearance: Gentle, even passes allow the colour and sheen to build gradually, helping to avoid runs, dry spray patches and patchy gloss levels.
Aftercare: Once coated, try to keep the surface free from tape pull, impact and aggressive wash down until the coating has had time to harden. Simple, mild cleaning products are usually sufficient.
Repeat orders: Batch information can be recorded so that future top ups can be mixed to the same colour and finish, helping return visits feel calm and predictable.

When paired with the correct primer this system can be suitable for many common substrates, including metal, correctly prepared plastics and timber. The aim is a smooth, reliable finish with good adhesion and stable colour under normal service conditions.
