Do I need a primer for metal?

You should always prime a surface before painting, and metal is no different. A metal primer, especially if used as an undercoat on existing paint, will give any new metal paint the best chance possible to adhere and develop over time. 

A good checklist to follow in deciding whether to use a metal primer is as follows:

  • Is the metal in bad condition already?
  • Is this new metal?
  • Is this metal located outside?
  • Is this metal already rusted?

If you answered “Yes” to any answer of these questions, you should be priming. Luckily, primers only ever need to see you using one coat to get the job done.

What is Zinc Phosphate primer?

Zinc Phosphate primers are formulated to have improved corrosion resistance. This makes them a good choice when you’re looking to prime exterior metal surfaces like fences exposed to the elements that run a higher risk of rusting quickly.

I have rust on my metal. How can I remove it?

You never want to prime a surface without firstly giving it a good clean up. It is quite common for previously painted metal to show signs of rust if the paint has chipped away in some corners and left the metal exposed to the elements. If you need to get rid of rust, using a Rodo Wire Brush can prove to be very handy.

I have grease on my metal. What should I do?

Grease will not let you get away with applying a primer normally, and you’ll want to try and remove any grease or oil from metal before applying a primer. Zinsser Universal Cleaner & Degreaser is a great product that blasts away oil, grease, oxidisation, and a whole host of other substances that would usually be difficult to scrub off.

How long do metal primers take to dry?

Different metal primers have varying drying times, but a decent primer will need a couple of hours to adhere, protect, and be ready to paint over. With the Dulux Metalshield products we have in stock, you would be looking at a drying time of around 2 to 3 hours before you could apply your first coat of metal paint. 

Can I use metal primer on a radiator?

Most domestic radiators have a maximum surface temperature around 80°C, although you should check with the manufacturer what maximum temperature your radiators get to before applying a suitable metal primer. The Metalshield primers in stock can be used on heated surfaces up to 90ºC, although we recommend checking that a primer is suitable before use.
