How to Spray Paint Metal Cabinet Knobs

Spray painting metal cabinet knobs is an easy and affordable way to update the look of your kitchen or bathroom cabinets. With some preparation and the right materials, you can transform dull and dated hardware into a fresh new accent. Here is a comprehensive guide on how to properly spray paint metal cabinet knobs for a professional finish.

Introduction

Replacing hardware is one of the simplest ways to update the style of your cabinets without a full renovation. Spray painting is an ideal technique for coating metal knobs and handles as it creates an even, smooth finish and allows you to easily match any color scheme.

When done properly, spray painted hardware looks clean, crisp, and factory-finished. The process does require some planning and prep work but overall it is a budget-friendly weekend project that can give your space a quick facelift.

Benefits of Spray Painting vs Brush Painting

There are several advantages to using spray paint instead of traditional brushed-on paint for cabinet hardware:

• Even coverage: Spray paint applies thinner, more even coats compared to brushing. This helps avoid drips and uneven texture.
• Smooth finish: The fine mist of spray paint creates a smooth, professional-looking finish. Brush strokes are avoided.
• Quick application: Spray painting is significantly faster than brushed painting for covering hardware pieces.
• Durability: Spray paint adheres tightly to metal for a long-lasting finish. Multiple thin coats create better adhesion than thicker brushed coats.
• Accessibility: Spray paint can easily coat all sides and grooves of decorative hardware. Reaching small details with a brush is tricky.

For these reasons, spray paint is the top choice for achieving flawless, professional results when painting cabinet hardware.

How to Prepare Metal Knobs for Painting

Proper prep work is crucial for ensuring the spray paint adheres correctly to the metal knobs. Follow these steps:

Remove Hardware from Cabinets

Use a screwdriver to detach all of the knobs and pulls from the doors and drawers. Keep hardware organized so it can be easily reattached later.

Clean the Surface

Wash knobs with warm soapy water and scrub to remove any existing grease, wax, or grime. Rinse and dry completely.

Sand Glossy Surfaces

If the hardware has a shiny or glossy finish, lightly sand with fine grit sandpaper to help the paint adhere better. Wipe away sanding dust.

Use Primer

Apply a thin coat of primer spray paint formulated for metal. This helps the topcoat stick properly. Let primer dry completely.

Set Up a Painting Area

Cover your work surface with newspaper or a plastic drop cloth. Have paper towels, painter’s tape, and gloves on hand.

The hardware is now prepped and ready for its fresh painted finish!

How to Choose the Right Spray Paint

When selecting a spray paint for metal knobs, consider the following factors:

Interior/Exterior Formulas

Only use interior paint for cabinet hardware. Exterior paints are not formulated to withstand indoor conditions.

Finish Type

Opt for a gloss, semi-gloss, or satin spray paint. These offer a durable yet smooth finish. Avoid flat/matte as it can look chalky.

Color Options

Many brands offer a huge selection of colors from neutrals to bold hues. Get sample sizes if needed to test colors.

Adhesion Properties

Ensure the spray paint is specially made to bond to metal surfaces like hardware. This is key for long-lasting results.

Enamel Formulas

Enamel paints provide an extra tough, scratch-resistant finish. Consider this upgrade for frequently used hardware.

Brand Reputation

Stick with reputable national brands like Rust-Oleum, Krylon, or Valspar for best results. Avoid generic bargain brands.

With so many choices available, you can easily find a spray paint that achieves the exact look you want.

How to Spray Paint Cabinet Hardware

Once you have prepped the surface and selected the right spray paint, follow these steps for applying:

Set Up Properly

Work outside or in a well-ventilated area. Arrange knobs on newspaper and place cardboard behind to block overspray.

Shake the Can

Vigorously shake the spray paint can for at least one full minute. This mixes the pigment evenly for consistent coverage.

Apply Primer

If needed, apply an even primer coat first and let fully dry before applying the topcoat color.

Mist on Paint

Hold the can 6 to 8 inches from the hardware. Apply light, even coats using a side to side sweeping motion.

Coat All Sides

Rotate the knobs to reach all sides and edges with the spray. Frequently rotate and turn pieces as you apply paint.

Let Dry

Allow each coat to completely dry before adding another. Drying times vary by brand, check label instructions.

Add Multiple Coats

Apply at least 2-3 thin coats for complete coverage, adding more if needed. Thin coats prevent drips.

Seal with Clear Coat

Finish off with a clear enamel spray sealant for an extra durable, scratch-resistant finish.

Allow to Fully Cure

Let painted hardware cure 24-48 hours after final coat before reinstalling to allow paint to fully harden.

Tips for Achieving a Flawless Finish

Follow these pro tips and tricks for professional spray painted results:

• Always test spray paint on scrap material first to ensure compatibility with the metal and desired results.
• Apply paint in a dust-free area without bugs, wind, or other debris that can stick.
• Use painter’s tape to cover any areas you don’t want coated in overspray.
• Time your spray distance and strokes to avoid drips or too much paint build up.
• Shake the can frequently between coats to prevent clogging.
• Use thin, even coats and slowly build up coverage rather than applying one thick coat.
• Add a clear topcoat for an extra smooth, polished look and to seal in the color.
• Let each coat dry thoroughly between applications for proper adhesion.
• Work in a well-ventilated area and wear a respirator mask to avoid inhaling spray fumes.
