How to Spray Paint Door Knobs: A Step-by-Step Guide

Spray painting door knobs can be a cost-effective and simple way to update the look of your home. Whether you want to match them to a new color scheme or give them a fresh new coat, spray painting is a quick and easy solution. In this article, we will guide you through the process of spray painting door knobs, and answer some frequently asked questions to help you achieve a professional-looking finish.

Step 1: Preparation
Before you start spray painting, you need to prepare the door knobs. Remove them from the doors and clean them thoroughly with a mild detergent to remove any dirt and grime. Once cleaned, use fine-grit sandpaper to lightly scuff the surface of the knobs. This will help the paint adhere better.

Step 2: Tape and protect
To avoid any accidental overspray, cover the surrounding area with plastic sheeting or newspaper. Use painter’s tape to cover any parts of the door knob you don’t want to paint, such as the latch or keyhole.

Step 3: Prime
Applying a primer is essential to ensure good adhesion and a smooth finish. Choose a primer specifically designed for metal surfaces. Shake the can well and spray an even coat of primer onto the door knobs. Allow it to dry completely according to the manufacturer’s instructions.

Step 4: Spray paint
Once the primer is dry, it’s time to apply the spray paint. Choose a high-quality spray paint specifically formulated for metal surfaces. Shake the can well and hold it about 6-8 inches away from the door knob. Begin spraying in a sweeping motion, making sure to cover all areas evenly. Apply multiple thin coats, allowing each coat to dry before applying the next. This will help prevent drips and ensure a smooth finish.

Step 5: Finishing touches
After the final coat of spray paint has dried, you can add a clear topcoat for added durability and protection. This step is optional but recommended, especially for frequently used door knobs. Apply the topcoat following the same process as the spray paint, allowing each coat to dry before applying the next.
