If you are tired of looking at your traditional door handles and have a low budget for home improvement, you need to use paint to upgrade these. By using specific shades, you can add color accents without the cost of replacing these.
It would be best to have a screwdriver, degreaser, sandpaper, styrofoam, drop cloth, metallic primer, clear coat, etc. Once you remove the doorknobs, you need to clean these knobs using a rag to get rid of oil and grime. Then using the right spray paint, you can transform the doorknob into an entirely new one. You can use a metal finish to give a new and expensive look to these old ones.
