This keeps small particles of dust and debris from mixing in with the paint and marring the finish. You can wash the knobs with water and any mild soap. Wipe the knobs completely dry with a clean cloth before sanding them.^{[1]

This will prepare the surface for priming, and will also help to remove any loose or flaked paint from the knob. Wipe the knobs with a tack cloth after sanding to remove any particles of paint or metal left by the sanding.^{[2]

You will not be able to handle the knobs while applying the primer or paint. This would create fingerprints in the finish. The simplest way to set the knobs up for painting is to lay them out on a sheet of plastic with their tops facing up. However, a more elegant solution can be prepared using a sheet of cardboard.
- Obtain a large sheet of sturdy corrugated cardboard; you can easily cut one out from a shipping box. Fold the sheet down the middle so that it holds a 45 degree angle. Place the folded cardboard on top of a flat surface so that it forms a "tent" shape. Poke the screw of each knob through the underside of the cardboard and secure the knobs just as you would when installing them in your drawers.
- You can now prime and paint the knobs in place on the cardboard support. The cardboard will keep the knobs from rolling and touching each other, and the angle will keep paint from pooling around the knobs. Make sure to lay down newspaper or another disposable material underneath the cardboard tent.

Clean metal primer is available in spray cans and can be purchased from nearly any hardware store. To apply it, shake the can as indicated in the directions, and spray the entire cardboard support in long, smooth passes. A thin layer is all that is needed, and will dry faster than a thick layer. Allow the primer to dry as per the can's directions; the primer should no longer be tacky to the touch before applying paint.^{[3]

Apply paint to the metal knobs.

This paint is designed to adhere well to metal. For a glossy and durable finish, use a spray paint that is designated as "enamel." This paint should be applied just as you applied the primer. Shake the can and spray the knobs in long, smooth passes. Keep the spray can moving at all times to avoid creating thick patches that may lead to drips. One coat of paint will usually be sufficient.^{[4]

Question

After primer and spray, my painted knobs are tacky feeling. What can I do?

Community Answer

Make sure your primer and paint are completely dry before adding another coat. You could Wait a day between coats. Also, make sure you're using the right paint for metal. It's not the same as for wood. Plasticized paint will peel right off metal.

Question

Is there any way I can paint them with a brush?

Community Answer

Yes, but you will have to experiment a little. It depends on the material you are painting, and the detail behind it. Sometimes a foam brush works better so you have fewer stroke marks left behind by the paint, but sometimes a small brush works well for details.

You will achieve the best results when using spray paint at a temperature between 50 and 90 degrees Fahrenheit (10 - 32 degrees Celsius).

When applying primer or paint, make sure to work in a well-ventilated area. If working outdoors, take precautions to minimize the risk of errant hairs or other debris blowing into the wet paint on the knobs.
