How to Paint a Barbecue Grill: Personal Experience

Depending on what type of barbecue grill that you have, there may come a time when you need to remove the old paint and apply a new coat. I have had to complete such a task twice in my life. The reason why I had to repaint a barbecue grill was related to rust damage. The grills in question were used heavily and the powder coating had gotten scratched up. The previous owners never bothered to touch-up the scratches and subsequently rust formed on the exposed areas. Of course that rust eventually spread to other areas of the barbecue and needed to be addressed once and for all. It really wasn’t all that time consuming, difficult or expensive to repair the rust damage. Here’s how I did it:

Cleaning and Removing the Rust

The first thing that I did was clean the barbecue grill with degreaser ($13), naval jelly ($6), soap and water. You can typically buy the degreaser and naval jelly at most major home improvement stores. Then I took a wire brush and some steel wool to the rusted areas. The rust was quite extensive, so I eventually switched to a Dremel tool. It made the task go a lot faster. I chose to use an emery impregnated disc for the large areas of the grill and an aluminum oxide grinding stone for the smaller and harder to reach places on the grill.

Preparing the Barbecue Grill’s Surface

Once I had the rust removed, I applied liquid sander ($7) to the barbecue grill with a paint brush. The liquid sander is designed to help the new barbecue grill paint stick to the old paint. Then I cleaned and dried the barbecue grill before pulling out the cans of primer and barbecue paint.

Painting the Barbecue Grill

Next, I coated the grill with a coat of primer and let it dry. Once the primer was dry, I continued the job by spray painting the barbecue grill with a can of black Krylon BBQ & Stove spray paint. It took me almost four cans of spray paint to get the coverage that I wanted. Afterward, I let the paint cure. I finished the job by firing up the grill and letting it run for 15 minutes just to get rid of any residual paint smells. Doing that seemed to work because when I actually used the grill to cook my food later in the day, I didn’t have any problems with funky odors or funny tasting foods.
