Is it suitable for metal, plastic, wood and uPVC?

Yes, with proper preparation and the correct primer for each substrate. Use plastic adhesion primers for plastics/uPVC, metal or etch primers for metals, sealing/priming for wood, and dedicated primers for glass or fibreglass.

How much will I need (coverage & coats)?

As a guide, a 400 ml aerosol covers up to approximately 2 m² per coat on a smooth, primed surface. Most projects need 2–4 coats depending on colour, surface profile and what is being covered.

How long does it take to dry and fully cure?

For 1K, recoat after about 10–15 minutes; typical cure is around 30 minutes depending on conditions. For 2K, recoat after about 20–30 minutes; touch-dry is roughly 40 minutes and full cure is usually 24–48 hours.

Can I use it outdoors and will the colour fade?

Yes, provided correct preparation and priming. Add UV Protection to help maintain colour on sun-exposed surfaces and consider a High-Resistance package for coastal or high-wear areas.

It’s supplied in 400 ml 1K or 2K aerosols (2K has a built-in hardener), litre tins, plus touch-up pots/pens. Choose finishes from Matt 0% to Full Gloss 90%.

Yes—prepare properly and use the right primer for each substrate:

Plastics/uPVC: use a plastic adhesion primer (see our plastic primer).

For safety and handling, see our data sheets: 1K · 2K/2K Air-Dry.

Please note: our paint is custom mixed and should be test-sprayed on a small, inconspicuous area before full application. We cannot accept responsibility for any colour difference once paint has been applied to your surfaces. If the colour is not accurate, please contact us to arrange a return.
