![]() This way the item will heat up with the oven. You will want to place the item in the oven as soon as you turn it on. If it does, repeat the process and add another coat. Take it out of the oven and check to see if it needs another coat of paint. Wait for it to be just a tiny bit tacky and put it in the oven.īake the painted object in the oven for about an hour. You don’t want the paint to be wet, but you don’t want it to be completely dry either. You should only wait a few minutes before putting the object in the oven. Give the paint some time to dry before you try to put it in the oven. You will then need to paint the product with the Rust-Oleum paint. Preheat the oven to 300 degrees Fahrenheit. If you need to remove the racks, do so before you even consider turning the oven on. The first thing you need to do is make sure your product will actually fit in your oven before you start. How to Bake Rust-Oleum Paintīaking Rust-Oleum paint is extremely easy. The result will be a solid, durable coat of paint that looks shiny and glossy with as little effort as possible. The process of baking Rust-Oleum paint is super simple and won’t take you very long to complete. It’s also a great way to cure between layers, and speed up the drying time. Baking paint will make it more permanent, and prevent any cracks or scratches in the future. So, can you bake Rust-Oleum paint? Luckily, you are able to bake Rust-Oleum paint. If you are painting with a Rust-Oleum paint, you might be wondering what the best way to seal and protect the paint is, when you are finished with your project.īaking painted objects is a great way to seal the paint. It stands up well to different elements, including heat. If brushing that doesn't work too well since the contact of the brush tends to disrupt the original application.Rust-Oleum is an incredibly popular paint for good reason. If you are spraying the paint, I find that you can apply two "coats" in one "application" which helps with the coverage and has only one dry cycle. If post baking after the solvents have flashed off, I sometimes go up to 200F if I'm in a hurry. Too hot and the solvents will boil and the finish will be ugly. How hot? I generally go for just hot enough to be uncomfortable to touch. ![]() It also helps to avoid sags in the paint. Warming the part before applying the enamel seems to help too. ![]() Round numbers, a chemical reaction's rate doubles for every 18 fahrenheit degrees so you don't have to make it a lot warmer to see a big benefit in cure time. I have had good luck adding some japan dryer to the paint to catalyze the cure and, if possible, heating the part in an oven or with a heater fan or something to warm up the part. So, you can probably apply multiple coats within the one hour window over and over, but the resulting film will take a long time to harden. It will skin over where the top layer of paint is exposed to air, but the rest of the material in the can will not harden up for weeks, months or ever (for practical purposes). You can see this if you leave a can of enamel open for a long time. The thicker the paint film, the longer the cure time since the thick film inhibits the availability of air to the lower layers of paint. Unlike lacquer type finishes which dry through the evaporation of a solvent, enamels will not re-disolve in their own solvent once they are cured which, as pointed out above, can take a long time. Enamel cures via a chemical reaction between air and the drying oils in the paint. ![]()
