A lot of people don’t think it’s possible to paint a barbecue, when in fact, it’s really quite simple. In this blog, I’m going to explain how to paint a barbecue. Follow these few simple steps and use a good quality paint, and you can’t go wrong.


How to Prep a Barbecue Before Painting


I’m just going to throw this out there and assume your barbecue is in a bit of a state. It’s probably faded, covered in grease, and possibly even rusty. Painting it will give it a new lease of life, but to paint it, you will need to prep it first.

Start by removing anything from the barbecue that you don’t want to paint. That might include handles, hooks for cooking utensils, or even a shelf. Anything remaining can be covered in masking tape to protect it while you work.

Next, empty any charcoal and remove the grill. I know you’re probably not going to paint the inside of your barbecue, but ash can become airborne while you’re painting and ruin your finish.

Then you need to get rid of any grease on your barbecue. If not, it’ll bleed through your paint work, and you’ll see blemishes. The best product I can recommend is Zinsser Universal Cleaner and Degreaser.

This cleaner is very strong, so wear a mask if you’re prepping your barbecue in an enclosed space. Simply spray on, leave for a couple of seconds, then wipe clean with a cloth and warm water. You’ll find it shifts grease faster than any cleaning product you’ve ever used in the past.

Once your barbecue is clean, you’re ready to sand it down. This is important for a couple of reasons; firstly, it removes any blemishes and rust. Secondly, it creates a ‘key’, which helps your paint to stick (thousands of tiny scratches which your paint can grip onto).

The paint I use on a barbecue is tried and tested, but it still needs to do a lot, so your prep needs to be right.

That concludes your prep. Just dust the barbecue off with a duster, and you’re ready to paint.

The actual painting is very easy. Get yourself a couple of tins of Maston Heat Resistant Spray. This stuff is available in black and silver for just north of £10 per tin (click here to see online prices).

Point the nozzle at your barbecue and start moving your hand before you press the trigger (this prevents you from applying too much material in one spot). You need the nozzle to be around 15 cm away from the barbecue while you apply the paint. Just pass from one side to the other and apply the paint evenly.


Maston Heat Resistant spray paint will endure temperatures to over 600 degrees, so it’s easily capable of withstanding the heat from a barbecue. You can apply it directly to rust too, which means there is no need for a separate primer.

Apply three light coats of spray paint to your barbecue and allow at least an hour in-between coats. Don’t try to apply too much paint at one time, otherwise it’ll look patchy.

The paint needs heat to fully cure, so don’t finish your last coat and then dive into your cool box for a fist full of burgers. Instead, remove the masking tape, replace the handles you removed, then fire up the barbecue. Leave the heat on for two hours, then allow to cool again. This will harden the paint.

Once cool, you can clean again, and start cooking. Your barbecue should look brand-new and the paintwork will last for years.
