Technical overview of BS 4-056 Aerosol Spray Paint

BS 4-056 Aerosol Spray Paint is a custom-mixed colour from our BS 2660 Aerosol Spray Paint chart, available as 1K (ready to use), 2K (integrated hardener for higher chemical and abrasion resistance) and 2K Air-Dry (non-isocyanate hardener). Finishes: Matt 0%, Satin 30%, Semi 60%, Full Gloss 90%. 2K aerosols are supplied as Acrylic Enamel only.

Surface preparation standards (plastics, metals, wood, uPVC)

Clean/degrease thoroughly, then key the surface (typical P400–P600 for plastics/metals). Use substrate-appropriate primers: plastic adhesion for plastics/uPVC; etch/anti-corrosive for bare metals; sealers/primers for wood; dedicated systems for glass/fibreglass. Correct priming improves adhesion and durability.

Application parameters (distance, passes, overlap, flash-off)

Spray at ~15–25 cm with steady speed and angle. Apply light, even passes with ~50% overlap. Flash-off: 1K ~5–10 minutes, 2K ~10–15 minutes depending on conditions. Use adjustable fan width to suit the area and limit overspray.

Recoat window and curing schedule (1K vs 2K)

1K: recoat after about 10–15 minutes; typical handling cure around 30 minutes. 2K: recoat after about 20–30 minutes; touch-dry roughly 40 minutes; full cure around 24–48 hours. Ambient conditions will affect all timings.

Coverage and target film build

Guide coverage is around 2 m² per coat from a 400 ml aerosol on a smooth, primed substrate. Plan for 2–4 light coats. Target around 20–40 µm total dry film thickness; a light aerosol pass can deposit roughly 10–15 µm depending on technique and conditions.

System compatibility (primers, clears, overcoating)

Use compatible primers and clears from the same system where possible. Avoid mixing dissimilar chemistries without testing. Respect recoat windows to protect intercoat adhesion and gloss. Always validate with a small test area.

Environmental conditions and safety

Apply in mild, dry conditions—ideally 10–25 °C with relative humidity under 75% and steady airflow. Keep the substrate at least ~3 °C above dew point. Use appropriate PPE (respirator, gloves, eye protection) and ensure excellent ventilation. Refer to the product data sheets for full guidance.

Trade Application Notes

BS 4-056 Aerosol Spray Paint is part of the BS 2660 Aerosol Spray Paint Colour Chart. Each order is batch mixed using Lechler binders and colourants, so repeat orders match across aerosols and tins for return visits and snagging.

Formats: 400 ml aerosols in 1K (ready to use) or 2K (with integrated hardener), 1 litre tins, plus touch-up pots and pens.
Finishes: Matt 0%, Satin 30%, Semi gloss 60%, Full gloss 90% to suit client specification and maintenance regime.
Surface prep: Degrease, abrade to a uniform key, remove dust and salts. Use the correct primer for the substrate and environment.
Masking and protection: Mask adjacent glazing, brick, signage and ground. Use sheeting and drop cloths to control fall-out around public areas.
Application control: Vari-nozzle cap allows wide or narrow fan patterns. HVLP-style atomisation helps with edge control and reduced overspray.
Overspray management: Plan wind direction, set screens where required and keep a safe perimeter. Night or early morning shifts help on busy sites.
Weather window: Apply on clean, dry substrates. Avoid rain risk and condensation. Follow temperature and humidity limits in the product data sheet.
Recoat and cure: Observe flash-off and recoat guidance from the TDS. Allow full cure before aggressive cleaning or handling.
2K handling: Mix accurately, respect pot life and dispose of waste responsibly. Use suitable PPE and ventilation.
Equipment: For aerosols, keep the can warm, shake thoroughly and maintain a wet edge. For tins, use compliant spray gear or mini-roller and fine foam for edges.
Coverage and finish: Apply light, even passes. Build film gradually for uniform sheen and durability.
Aftercare: Protect fresh coatings from tape pull, impact and wash-down until cured. Provide the client with basic cleaning guidance.
Repeatability: Batch codes are recorded so future top-ups can be mixed to the same colour and sheen for consistent touch-ins.

Suitable for a wide range of substrates when paired with the correct primer. Delivers smooth flow, reliable adhesion and long-term colour stability under normal service conditions.

Frequently Asked Questions

BS 4-056 Aerosol Spray Paint is a custom-mixed colour from our BS 2660 Aerosol Spray Paint chart, available as:

1K aerosol/tin: ready to use; general purpose.
2K aerosol/tin: integrated hardener for higher chemical/abrasion resistance.
2K Air-Dry: 2K performance with non-isocyanate hardener for easier handling.

Finishes: Matt 0%, Satin 30%, Semi 60%, Full Gloss 90%. 2K aerosols are supplied as Acrylic Enamel only.

Clean/degrease: remove oils, silicones and residues (use panel-wipe; lint-free cloths).
Key the surface: typical aerosol prep is P400–P600 (plastics/metals), vacuum then tack-rag.
Primers: plastic adhesion for plastics/uPVC; etch/anti-corrosive for bare metals; sealers/primers for wood; dedicated systems for glass/fibreglass.

Correct priming vastly improves adhesion, opacity and long-term durability.

Spray distance: ~15–25 cm; maintain a constant angle and speed.
Technique: light, even passes with ~50% overlap; build film gradually.
Flash-off between light coats: 1K ~5–10 mins; 2K ~10–15 mins (conditions dependent).
Nozzle control: use the vari-nozzle (wide/narrow) to suit area and reduce overspray.

Always test on a small area to validate settings before full application.

1K: recoat ~10–15 mins; typical handling cure ~30 mins.
2K: recoat ~20–30 mins; touch-dry ~40 mins; full cure ~24–48 hrs.

Temperature, airflow and humidity significantly affect all timings—verify on your substrate.

Coverage guide: ~2 m² per coat from a 400 ml aerosol on a smooth, primed substrate.
Typical passes: 2–4 light coats for uniform colour and gloss.
Film build: plan for ~20–40 µm DFT across the system; a light aerosol pass can deposit ~10–15 µm (approx.).

Heavily textured/porous surfaces and strong colour changes may require additional coats.

Use system-appropriate primers and clears from the same family where possible.
Avoid mixing dissimilar chemistries without testing; perform a small adhesion/solvent-rub test first.
Observe recoat windows to protect intercoat adhesion and gloss.

For detailed guidance, refer to the data sheets below.

Ambient: ideally 10–25 °C, RH < 75%, steady airflow; substrate temperature at least ~3 °C above dew point.
PPE: suitable respirator, gloves, eye protection; ensure excellent ventilation.

See data sheets: 1K · 2K/2K Air-Dry.

Please note – Our aerosol cans, litre tins and touch up and repair pots/pens are custom mixed and should be tested before application. We do not take responsibility for any colour difference once you have applied the paint to your surfaces. If the colour is not accurate, please contact us to arrange a return.
