Spray painting metal file cabinets can give old, worn cabinets a fresh new look. With some prep work, the right spray paint and technique, you can easily transform dull and outdated metal cabinets. A new coat of paint goes a long way in improving the aesthetics of your office or workspace. This guide will provide tips for properly preparing and spray painting metal cabinets for a professional-looking finish.

Steps to Follow When Spray Painting Metal File Cabinets

Clean the Cabinets Thoroughly

Before starting to spray paint, it is crucial to thoroughly clean the metal filing cabinets. This helps the paint adhere properly. Follow these steps for cleaning:

• Remove all contents from the filing cabinets. Make sure to label the contents to keep your files organized.
• Use a degreaser or cleaner formulated for metal to clean all surfaces of the filing cabinets. Apply the degreaser and let it sit for 5-10 minutes before wiping away.
• Pay close attention to handles, edges and any oil/grease spots. These attract dirt easily. Scrub these areas to remove any grime or residues.
• Rinse the cabinets with clean water and let them fully dry before moving onto sanding.

Sand the Cabinets

Lightly sanding the metal filing cabinets will help the spray paint adhere better. It creates a roughened, textured surface for the paint to cling to.

Use 150-220 grit sandpaper and sand in the direction of the metal grain. Make sure to sand all surfaces – sides, fronts, backs, doors, handles, lips and edging.

Sand just enough to rough up the surface slightly. Be careful not to scrub too hard as you can expose the bare metal underneath.

After sanding, wipe the cabinets with a dry cloth to remove any dust.

Fill Any Holes or Imperfections

Examine the cabinets closely and use a metal filler compound to patch any holes, dents or cracks.

Sand the filler once dry so it is flush and even with the surrounding area.

Make sure the surface is clean and free of any dust before painting.

Remove Drawers and Hardware

Removing any removable parts like handles and drawers will make spraying the cabinets much easier.

To remove drawers, slide them out fully and lift up when pulling out. The drawer should detach from the slider.

For handles and knobs, try unscrewing them first before forcefully pulling them out.

Set all hardware pieces aside and label them to make reinstallation easier.

Mask Off Sections Not Being Painted

Cover any portions of the cabinets you don’t want painted such as the interior of the cabinets or edges along walls.

Use painters tape, drop cloths, or masking paper to cover these areas.

Mask off the walls, flooring and other surfaces near the cabinets as well. Spray paint can travel far and easily stain surrounding areas.

Use Primer Spray Paint

For the best adhesion, always start by applying 1-2 coats of primer spray paint formulated especially for metal.

Primer helps the topcoat stick to the metal cabinets better. It provides a uniform surface for the topcoat to bind to.

Let each coat of primer fully dry before adding another coat. Refer to the spray paint can instructions for exact drying times.

Once the primer is fully dry, lightly sand it with fine sandpaper. This helps the topcoat paint adhere better.

Apply Topcoat Spray Paint

Now you’re ready for the fun part – applying the topcoat spray paint in your desired color!

Refer to the spray paint instructions for exact application guidance. In general:

• Use long, even strokes and keep the spray can 8-12 inches from the surface.
• Mist on 2-3 thin coats rather than 1 thick coat for a smoother finish. Let each coat fully dry between applications.
• Shake the can vigorously before and during use to properly mix the paint.
• Spray side-to-side horizontally then follow up by spraying vertically up-and-down. This ensures thorough, even coverage.
• When spraying edges or small surfaces, use short quick bursts to prevent drips or pools of paint.

Apply as many coats as needed for full opaque coverage. Darker colors may require more coats than lighter ones.

Remove Masking and Reinstall Hardware

Once the topcoat is fully dry, carefully remove all masking materials. Reinstall all the hardware and drawers.

Now stand back and admire your revamped filing cabinets! With some essential preparation and technique, you can achieve a flawless, professional-looking spray painted finish.

Tips for Successful Metal File Cabinet Spray Painting

Follow these handy tips for superior results spray painting your metal cabinets:

• Pick the right spray paint – Use a topcoat spray paint formulated specifically for metal. Look for oil-based enamels or latex bonded to metal. Avoid universal spray paints.
• Prepare the space – Paint outdoors if possible. If painting indoors, cover any nearby surfaces and ventilate the room well.
• Follow safety precautions – Wear a respirator and work gloves. Read all instructions.
• Spray when humidity is low – For less risk of drips, bubbles or orange peel texture, paint when humidity outside is low. Avoid rainy days.
• Spray in thin coats – Applying many thin coats creates a smoother finish than a few thick coats.
• Allow proper dry time – Rushing between coats causes drips, runs and uneven coverage.
• Start/end spray strokes off the cabinets – This prevents drips from starting and stopping the spray directly on the metal.
• Spray all sides – Don’t forget the cabinet tops, bottoms and sides. Spray all areas for full coverage.

Following these tips will help you achieve professional spray painted filing cabinets. Take your time and don’t try to rush through the process. Proper preparation is also key for beautiful long-lasting results.

FAQs About Spray Painting Metal File Cabinets
