Nothing gets a weekend or a holiday going like turning up your grill and barbecuing up some meat and vegetables. While a new barbecue grill looks pristine and in excellent working order, it will degrade with time, even with consistent maintenance. Repainting your grill is a quick way to breathe new life into your grill and get it looking new again. However, as you plan to paint it, you are probably asking, can you paint the inside of a grill?
I do not advise painting the inside of a grill. Traditional paints inside your grill will eventually chip and get some toxic materials into your food as it cooks. Fortunately, there are several alternatives for coating the inside of your grill other than paint that offer several advantages and are food safe, as discussed in this article.
Regular and proper maintenance of your grill can keep it running and operating smoothly for up to ten years. This article will focus on safely painting your grill, what paint to use, and several maintenance tips for your grill.
How Do You Prepare a Grill for Painting?
Adequate preparation not only saves you a lot of time and effort but also ensures that any paint job you undertake will endure. When painting your barbeque grill, here is how you can best prepare it before you ever pick up the paintbrush.
Step 1. Disassemble the grill
If you are refurbishing a built-in grill, you can remove the fire pit from the base. However, if the grill is portable, disassemble it entirely. Remove the grill racks, legs, and all other hardware and put them aside. Also, remove all the other assemblies such as the knobs, handles, side trays, and any wooden parts and store them safely.
If your bolts are too rusty to reuse, plan to replace them from the hardware store. Pull off the plastic caps from the grill switches if you can, and if you cannot, pull them off, find the set screw, and take them off. You should store all these parts as safely as possible as you will need them when reassembling the grill later.
Step 2: Cleaning
Grease is paint’s enemy and will repel any paint you apply, making all your work naught. Cleaning your grill is a multi-step process with different tasks including:
- Soak the removable parts
Soak the grill parts such as the grease catchers and the grates in warm, soapy water for around 30 minutes, and then scrub off any food debris, smudges, and grease.
- Remove any ash
With the grill accessories removed, you can then remove any ash collected in your grill.
- Scrape off any charred flakes and rust
Your grill will likely have burned, blackened areas inside it. If so, you will need to take care of them before painting. Grab a plastic knife and scrape off as much of it as you can. Be careful not to use any toxic cleaners that may be harmful when exposed to grilling food.
Also, hosing the grill down is a great way to eliminate any charcoal build-ups- if you are using a charcoal grill.
After scraping off the interior, allow the grill to dry in an open space as you remove any rust from its exterior. If the rust on the body of that grill is not that severe, a brush might be enough to remove the rust.
While most grills are made from cast aluminum and may not rust, some smokers are of steel, which will rust badly after the paint wears off. Leaving any rust on the surface is a recipe for disaster as it will continue damaging your metal even if covered with a fresh coat of paint.
Step 3: Remove any existing paint
Removing the old paint is a great way to ensure that the paint adheres to the surface. You can remove the paint by scrubbing the surface using a wire brush. If this is not enough to strip the surface, you may need to invest in a more aggressive wire brush, though you must use it carefully. If there are still any rusted areas, you can quickly go over them using sandpaper.
Try to get down to the base metal of your grill. However, you do not need to get off every little bit of paint before you paint; ensure the grill surface is smooth, does not have rust, and is clean.
Step 4: Wipe the grill down.
After stripping the paint and removing the rust, you can use paint thinner to wipe down the entire grill to remove any metal dust. However, it is important to note that paint thinner is flammable, and you should handle it with extreme caution.
Step 5: Protect the parts that you won’t paint.
Cover the grill parts you do not intend to paint, such as the valve and knob connections, with painter’s tape. Ensure that you attach the tape securely to avoid having any paint infiltration.
Step 6: Give your grill a fresh coat of paint.
After careful preparations, you can apply a fresh coat of paint on your grill, as detailed below.
How to Paint the Inside of a Barbeque Grill
If you choose to paint the inside of your barbeque grill, doing it right will help to ensure your grill looks amazing and lasts long. Read on for a step-by-step guide on painting your barbeque grill.
Step 1: Paint your grill.
After following the above procedure above, you can then paint the grill with the main show. The coats you use will depend on the color saturation you want to achieve and the paint you are using. Patience is how you get the best results when painting.
Instead of going in with a single heavy coat, it would be better to have several thinner coats applied precisely. As you apply the multiple coats, be sure to let the paint dry completely before applying subsequent coats.
Spraying the paint on your grill surface is the best way to get a smooth, seamless look on your grill. Make sure that you use paint that is specifically labeled as heat-resistant and allow the final paint coat to dry for a day before you use the grill.
Alternatively, you can choose to have your grill painted professionally. Take your grill parts to the nearest powder-coating shop and spray them with the powder coating used on exhaust headers. This is an excellent option for a grill since this powder coating can resist extremely high temperatures while also available in numerous finishes.
Step 2: Reinstall the accessories.
After your grill is fully painted and dry, it is now time to reassemble it. Start by removing all the painter’s tape that you used to keep certain areas paint-free, and then return the knobs and other hardware you removed.
If some parts are too rusty or damaged to use still, this is an excellent time to replace them with new parts. You can also choose to install some added hardware to your grill for greater user convenience.
Step 3: Season and pre-heat the grill
Seasoning the grill constitutes covering the interior surface of the grill with cooking oil to help seal the surface. On the other hand, pre-heating is necessary to bond the cooking oil to the grill’s surface and burn away any remaining debris.
Does BBQ Paint Need Primer?
With the proper surface preparation and the right paint, you can go directly to applying paint to your grill without primer. When using most high-heat paints, you will likely not need to use a primer. This is because most high-heat paints are usually self-priming and do not require additional primer.
However, if you must apply primer, make sure you use a heat-resistant primer before applying the high-heat paint. This extra layer of primer will work to provide an extra layer of protection against harsh conditions.
Can You Use Rustoleum High Heat Inside Grill?
As the description implies, high-heat paints withstand far greater temperatures than room temperature. Unlike normal paints, these paints continue to provide desirable results even at higher temperatures. Grills, which we often subject to open flames and high- heat, are more vulnerable to damage and need a protective coating.
First, it is essential to note that traditional, liquid-based pant is a huge no for the inside of your grill. However, can you use Rust-Oleum high heat paint inside the grill? The paint will eventually chip and get into your food, putting you at risk of consuming harmful substances.
Rust-Oleum high-heat paint remains colorfast and retains its finish for up to 1200 degrees Fahrenheit, making it suitable for painting grills.
What Paint to Use On Grills?
To get the perfect blend of durability, performance, and safety from your paint, there are several selction criterai you must think on. Since we constantly expose grills to very high temperatures, high heat resistance is the least of these requirements. High-heat paints continue to provide surface protection and have high performance, even in high-heat environments.
Below is a comprehensive guide on what to consider before you choose high-heat paint for your grill.
- The temperature range
This is arguably the most important requirement to check on before settling for a high heat paint. Different paints will have different pre-determined optimum operating temperature ranges depending on their composition. Find out the highest range offered by the paint manufacturer and then decide based on your specific requirements.
For grills, it is best to choose paints that offer protection higher than your expected temperatures. For example, say you expect your grill to reach 600 degrees Fahrenheit, use paint that offers protection for a temperature well above that, say 800 degrees Fahrenheit.
When looking at the temperature requirements, make sure you check the protection offered for peak temperatures and continuous temperature. There may also be paint manufacturers that lie about the heat resistance of their products. Therefore, always research the product beforehand and choose one with a reputation for high performance and trustworthiness among its customers.
- The environmental conditions
When painting a grill, the paint needs to withstand more than just high temperatures, especially if the grill is used outdoors and is open to environmental conditions. Grills that are largely exposed outdoors will also require protection from the sun’s UV rays and the elements such as rain.
- Your requirements
What features do you want in your paints? Do you only want heat-resistant paint, or are there other performance points that you are interested in? Another feature that is just as important for a barbecue grill is corrosion protection. Paints that offer corrosion protection will allow you to go longer periods with your grill looking great without needing to repaint it.
- The film coating thickness
Today’s market for paints offers products with a wide range of film thicknesses. Thin-film paints stay flexible easily and maintain their core properties even when exposed to high temperatures.
On the other hand, Thick-film coatings are great for offering support, firmness, and the ability to build higher films in high temperatures. Thicker-film coatings also stay intact longer. You must choose a paint with your preferred characteristics.
- Durability
For high-heat locations such as a grill, durability is of great concern. This is especially true for grills exposed to outdoor conditions. The best way to confirm the durability of a certain product is to check with users of the product. Read reviews and consult friends who have already used the product to check whether its durability claims are valid.
- Drying time
The drying time for the paint is also an important feature to watch for, especially for permanently outdoors grills. While the drying time of inside grills may not be as important, you will want any outdoor grill to dry before you expose it to elements such as snow and rainfall.
Can Grill Grates Be Painted?
Even if you usually practice consistent grill maintenance, your grate will eventually not look its best with time. Nevertheless, we do not recommend painting the grill gates as they contact the food. Instead of using paint, you easily recoat your grill gates with oil.
You can follow these steps to recoat your grill gates effectively.
Step 1: Clean the grill gates
Before you recoat the grill gates, you will first need to give them a thorough cleaning. Remove the grate from the grill and set it aside. Then soak the grate in warm water with some dishwashing soap for a few hours to loosen up any food debris stuck to the grate.
After the grate has soaked for a while, scrub it with a steel-bristle brush to remove any debris. If the grate is stainless steel, use a nylon brush to clean it and wipe with a soft cloth if made of cast iron. You can then rinse the soapy water off and let the grate dry.
Step 2: Remove the rust
If your grill gate has any rust on it, you can resolve this by scrubbing it until all the rust comes off. Then rinse the grate with water and let it dry before recoating.
Step 3: Recoat the grate.
Before applying olive oil to the grate, heat the grill to approximately 250F on a gas grill or until the charcoal turns to ash in a charcoal grill, then put the grate back on the grill and heat it. Take the grate from the grill and spray it with olive oil, making sure to coat every surface fully. Then place the grill back on the heat for around three hours. Recoat the grate surface again with olive oil and return to the heat for another two to three hours at a temperature of about 200 degrees Fahrenheit.
Does Rustoleum High Heat Paint Need Primer?
As mentioned above, most high heat paints are already self-priming and do not need you to have a base coat of primer, though you can apply one. If you apply primer, you need to make sure that the primer is also heat resistant.
Apart from the self-priming paint, surface preparation also plays a key role in whether or not you will need to prime your surface. If you take the time to clean the surface and remove any rust, flakes thoroughly, and other debris, you can paint the surface without a primer. A clean, clear surface will be best for paint adhesion.
Is Rustoleum High Heat Paint Durable?
Rust-Oleum is a brand that has been producing protective coatings and paints for decades. The brand has cultivated a large base of loyal and enduring customers for a reason. Rust-Oleum paint is a market leader in producing durable paints. However, as with all other paints, the durability of a coat of paint also depends on other factors.
Paint will adhere better and stick longer to a well-prepared surface. To get the best performance, ensure that you clean the surface you plan to paint thoroughly. Also, if there is any old and damaged paint on the surface, strip it down before applying a new coat. While primer is not necessary, applying a primer to the surface wouldn’t hurt.
What Colors Does High Heat Spray Paint Come In?
Color is an important feature of any paint you hope to use for your grill. A wide selection of grill paint colors will allow you to choose a color that complements your surroundings beautifully. High heat paints come in a wide variety of colors ranging from the darkest black to a bright red.
Some of the colors you can find high heat paint include gray, white, flat white, brown, black, aluminum, beige, green, silver blue, purple, and several others. These colors also come in a range of shades and different types for each color.
How Do You Paint the Lid on a Weber grill?
The process of painting the lid on a weber grill is largely no different from the grill painting process that we have outlined above. When painting the outside, make sure that you adequately prepare the surface. Clean any debris, scrape off any rust or charcoal flakes, strip away any old paint, and paint the freshly exposed grill surface.
How Do You Keep Paint from Peeling On the Grill?
One of the main challenges faced by almost anyone who has ever used a grill regularly for some time is the appearance of what seems like peeling paint on the inside of the lid. While this may look like a serious problem, it has a simple explanation and is equally simple to fix.
It is not paint peeling from your grill but a deposit of smoke and grease that has collected as you used your grill. As you continue using your grill, smoke and grease vapor will slowly oxidize into carbon. The resulting product will collect on the inside of your lid. As the deposit starts peeling, it will start from the center and radiate outwards.
The good news is that these deposits are not toxic. However, regularly removing any build-up is a sound idea. Removing these deposits is also not so hard to do. All you need is a brush that you will use to brush off the particles before grilling.
While removing these deposits is fairly easy, preventing them from forming is even more prudent. Wipe down the grill surface using paper towels or a mild soap and water solution while the grill is still warm right after every grilling session.
Final Thoughts
Painting is an integral part of grill repair and maintenance, and if done well, can dramatically increase the life span of your grill, not to mention the aesthetic appeal. There are also plenty of food-safe options to coat the inside of your grill protectively, as discussed above. Still, the question remains,
Can You Paint the Inside of a Grill
Although we do not recommend you paint the inside of your grill, you can use heat-resistant paint to coat it if you must. Unlike traditional liquid paints, these can withstand higher temperatures and the open flames inside a grill.
