Before starting your paint job, you should check with your appliance manufacturer and ensure that the paint is suitable for the surface and here are three main steps that you should carefully follow to achieve great result.

Prepare the surface:

Firstly, you should check and remove any rust, blistering or peeling on the surface of the wood stove. Sanding, sandblasting or grinding is a good way to help you at this time.

After that, don’t forget to examine oil, dirt, grease or other contaminants because these prevent the paint from sticking to the stove. Then use a solvent degreaser to cleanse them.

Next, prepare glasses, gloves and anything else that can protect you from getting paint.

Apply the paint:

The first thing is to shake the can for about 1-2 minutes for the sake of mixing the compound together nicely. This guarantees that the solvents and pigments of the paint are mixed well. To get the best results when spraying, the temperature of the surface of the wood stove and the air are from 65 to 85 degrees. This is the most optimal temperature for the paint to work well.

It’s okay to soak the paint under hot water for 2 minutes to heat the paint but we highly recommend using low heat for better quality. But avoid overheating or exposing it to an open flame.

Start painting:

Before doing, you need to tape off parts of the grill that you don’t want to paint like knobs, handles, etc. Then apply the first coat! Hold a can of heat resistant spray primer about 12 inches away from the surface of the grill and spray.

Try to scrape a small area on its surface with a screwdriver blade and check the flaking to know whether it had been painted or varnished before. If not, examine any pitting from heavy rust with sandpaper (from 40 to 60 grits). Then sand the surface with fine-grit sandpaper (from 80 to 120 grits) to remove rust and get a smooth surface. In case the radiator was painted, you need to check the existing paint for the lead by using a lead paint test kit.

• If the test is positive, you need to use a professional refinisher to remove the paint.
• If the test is negative, avail a putty knife to scrape away the paint from the surface. After that, sand it as we mentioned above.

You should prime it first with an even and smooth coat before painting for better results. Shake and hold the can upright and at a distance of 10-16 inches from the radiator. Then spray in a back-and-forth motion. This will not only give a fresh surface but also protect against upcoming rust issues. And let it dry thoroughly.

Paint the radiator:

Try to apply the same technique as the primer by spraying another coat of the heat resistance spray paint over the surface.

Let the first one dry for 5-7 minutes (or according to the instructions of the paint) and then apply one or more to get the desired finish. Finally, allow it to dry completely.
