Introduction
Metal file cabinets are a staple in many offices and homes. They provide a convenient way to organize documents and keep them secure. However, over time metal file cabinets can start to show their age through faded paint, scratches, dents or other cosmetic issues. Redoing metal file cabinets is an easy DIY project that can give new life to old cabinets and transform the look of your office or home.
In this comprehensive guide, we will walk through all the steps needed to redo metal file cabinets. We will cover cleaning, prepping, priming, painting techniques, adding new hardware, and more. With some simple supplies and a little bit of time, you can make your tired old file cabinets look brand new again!
Supplies Needed
Redoing metal file cabinets requires just a handful of supplies:
- Cleaning supplies like all-purpose cleaner, scrub brush, rags
- Sandpaper – 180 and 220 grit recommended
- Primer – Rust inhibiting primer ideal for metal
- Paint – Either spray paint or regular brushed on paint will work
- Small paint brushes for trim and hard to reach spots
- New cabinet hardware like handles/knobs if desired
Make sure to get an appropriate primer and paint for metal surfaces. Regular wall paints will not adhere properly. An all-in-one rust inhibiting primer and paint made specifically for metal makes the project easier.
Gather all supplies before starting to make the process go smoother. Wear old clothes and work in a well-ventilated area when painting. Now let’s get started with prepping the cabinets!
Thoroughly Clean Cabinets
Before painting, it’s critical to clean the file cabinets thoroughly to remove any dirt, grease, or residue. This helps the paint adhere properly. Here are the steps for cleaning:
- Remove all files and paperwork and wipe out any dust or debris inside the drawers
- Use a degreaser or all-purpose cleaner combined with warm water on a rag to wipe down all exterior surfaces
- Pay close attention to handles, edges and any textured surfaces where grime can collect
- Let cabinets dry fully after cleaning before moving onto sanding
Cleaning may be the most tedious step, but it makes a big difference in how well your paint job turns out. Take your time and get the metal as pristine as possible before painting.
Sand Down Surfaces
Once cleaned, sanding is the next vital preparation step. This helps rough up the surface so the primer and paint can adhere properly.
Start with 180 grit sandpaper to remove any large paint flakes, rust spots or other imperfections. Sand all surfaces thoroughly, including inside drawers. Pay extra attention to areas with visible scratches, chips, or damages.
Follow up with 220 grit sandpaper for a smoother finish. The goal is to rough up and dull the surface, not remove layers of metal. Going back over everything with finer 220 grit helps even out the surface.
Make sure to wipe away all sanding dust with a dry cloth when finished. Now the cabinets should be ready for priming.
Apply Primer Coat
Priming is arguably the most important step in the painting process. Primer creates a surface that paint can stick to. Follow these steps for priming:
- Use painter’s tape to cover any areas you don’t want primer getting on
- Make sure surface is free of any residual dust from sanding before starting
- Apply 1-2 even coats of metal primer, allowing proper dry time between coats
- Pay special attention to any edges, hardware, corners etc.
- Allow primer to fully dry per manufacturer instructions before painting
Applying primer properly is crucial for getting an even base layer. This helps the final paint go on smoothly. Don’t try to rush through the priming stage. Allowing proper dry time between coats is key. Once fully dry, the cabinets are ready for fresh paint!
Paint Cabinet Exteriors
Time for the fun part – seeing the freshly painted cabinets come to life! Here are some tips for the painting process:
- Spray paint makes for quick, even coverage but requires masking off other objects in the area. Follow directions for proper spray technique. Apply multiple light coats for best results.
- Brushed on paint takes more time but avoids the hassle of masking. Use small foam rollers and angled brushes for a smooth finish. Apply in thin, even coats allowing proper dry time between.
- Paint the cabinet boxes first, then drawers and finally cabinet fronts/doors for easiest access.
- Check corners and crevices to ensure complete coverage and avoid drips. Backbrush as needed for an even finish.
- Apply 2-3 coats for best coverage and color depth or as recommended by manufacturer. Allow full drying between coats.
Take your time with the painting steps for a professional looking finish. The prep work should allow the paint to apply smoothly.
Paint Cabinet Interior and Drawer
The interior of cabinets and drawers often go overlooked when painting. But completing them makes a huge difference in the overall finished look. Here are some quick tips for painting cabinet interiors:
- Use a small angled trim brush to paint the back panel and side walls
- Paint drawer undersides and drawer front underneaths
- Use quick drying paint when possible to avoid sticking
- Only 1-2 thin paint coats needed inside since it won’t be handled/touched
- Paint a little bit into edge banding for a seamless look
Covering the unfinished interior prevents seeing chips down the road. It makes the redo look complete when you open drawers and doors.
Apply New Hardware if Desired
The original hardware like handles and hinges are often perfectly fine to reuse after painting. But replacing hardware is an easy upgrade option.
Browse home improvement stores, online boutiques or secondhand shops for knobs and handles that match your style. Look for properly sized handles to fit your cabinet holes.
Use a screwdriver to detach old hardware. Attach new handles using provided hardware. AddDetails like brushed nickel or bronze finishes can really change the overall look.
Swapping hardware is an inexpensive way to finish off your redo. But reusable original hardware also helps maintain a vintage or retro feel if preferred.
Add Protective Clear Coat (Optional)
For added protection on heavily used cabinets, applying a clear top coat is an option. A clear sealer helps protect the fresh paint from chips, scratches, and wear and tear.
Make sure paint is completely cured first before applying a clear coat. This usually takes 1-2 weeks. Quick drying enamels may cure faster.
Use a clear polyurethane sealer for best results on high traffic areas. Carefully apply 1-2 thin coats with a brush or roller following manufacturer instructions.
Adding a clear coat is recommended for cabinets in busy offices, kitchens, or other high use areas. For home office or minimally used cabinets it may not be needed.
Let Paint Fully Cure Before Use
Now comes the hardest part – waiting for the paint to fully cure before putting your cabinets back into service!
It can take 1-2 weeks for paint to completely harden and cure depending on humidity, temperature and paint type used. Latex and enamels may cure faster than oil based.
Resist the urge to start loading cabinets up right away. Give the paint adequate time to cure to avoid dents, scratches or stuck drawers.
Once fully cured, you can reload files, office supplies, dishes or other items as needed. Your cabinets have a fresh new look and are ready to organize again!
