  • FREQUENTLY ASKED QUESTIONS

1. Is this paint suitable for all types of radiators?

Yes, Pro-Spray Radiator Paint is suitable for most domestic radiators, including steel, aluminium, and cast iron. It can also be used on towel rails and the exterior of hot water tanks.

2. Do I need a separate primer before using this spray paint?

No primer is needed. Pro-Spray uses a 3-in-1 formula that primes, undercoats, and overcoats in one, saving time and effort.

3. How heat-resistant is this paint?

Pro-Spray Radiator Paint is 100% heat resistant up to 100°C, making it ideal for surfaces that get warm during regular radiator use.

4. How long does it take to dry?

The paint is touch-dry in 10–20 minutes, depending on conditions. It fully cures in 24 hours, after which it's heat- and water-resistant.

5. Can I spray this on a radiator that’s already painted?

Yes — but it's important to lightly sand the surface first and check compatibility by testing a small, inconspicuous area.

No. Pro-Spray Radiator Paint features a non-yellowing formula that keeps its original colour and finish even under heat.
