Refinishing outdoor metal furniture can help restore it to its former glory and protect it from future wear and tear. With some effort and the right materials, you can make your outdoor metal furniture look brand new. This comprehensive guide will walk you through all the steps needed to properly refinish outdoor metal furniture.
Assessing the Current Condition of the Furniture
Before beginning the refinishing process, you need to thoroughly examine the current condition of the outdoor metal furniture. This will help you identify all areas that need attention and determine the best approach for restoring the pieces.
Here are some things to inspect:
Check for Rust
Rust is one of the biggest enemies of outdoor metal furniture. Check both the visible and underside surfaces of the furniture for any rust spots or corrosion. Tap a screwdriver on spots that look suspicious to see if the metal flakes or falls apart, revealing rust underneath.
Test for Loose Joints and Hardware
Wiggle parts of the furniture to check for any loose joints. Also try loosening and tightening screws and bolts to see if any hardware needs tightening or replacement.
Look for Dents and Scratches
Inspect the surface thoroughly for any dents, cracks, or scratches in the metal. Make notes on the depth and severity of any blemishes.
Evaluate the Paint or Finish
Determine if the current paint or finish is cracked, chipped, or peeling. Check how much of the underlying metal is exposed.
Check for Previous Repairs
Note if there have been any previous repairs made and whether these need redoing as part of the refinishing process.
Thoroughly examining the furniture will help you formulate a refinishing plan targeting all problem areas for correction.
Cleaning and Prepping the Furniture
Once you have assessed the current condition, proper cleaning and prep work is the next essential step before starting the refinishing process.
Remove All Hardware and Accessories
The first task is to completely disassemble the furniture by removing all hardware, cushions, fabric, and any detachable accessories. Number and label pieces if necessary to ensure proper reassembly later.
Get Rid of Dirt and Grime
Use a stiff scrub brush and a degreaser or all-purpose cleaner to thoroughly scrub the furniture and get rid of all built-up dirt, mold, mildew, bird droppings, etc. Rinse off with fresh water afterwards.
Smooth Any Rough Surfaces
Use 100-grit sandpaper to smooth out any small scratches, dents, or rough areas in the metal surface in preparation for painting or finishing later.
Clean Off Rust and Corrosion
Apply a rust remover solution liberally on any rust spots and let it sit per product instructions, usually 10-30 minutes. Use a wire brush to scrub off any loosened rust, then wash the furniture with water. Rinse and let dry fully.
Remove Chipping Paint and Finish
Use a paint scraper, putty knife, or wire wheel brush to strip any cracked, peeling, or chipped paint from the metal. Sand down to smooth bare metal.
Thorough cleaning and removal of all deteriorated finishes or corrosion prepares the metal furniture for accepting new paint, primer, or finish.
Choosing a Finish Coating
There are several options when selecting a protective finish coating for refurbishing outdoor metal furniture. Consider the following factors when deciding on the best finish:
Durability
Since the furniture is outdoors, it needs a coating that resists chipping, fading, and damage from sun, rain, wind, and other elements. An industrial-grade epoxy or urethane works well.
Ease of Application
Opt for paints or finishes that go on easily with a brush or sprayer and don’t require advanced skills or multiple coats.
Color Options
Pick a finish coating that is available in a wide range of color options to match your style. Metallic finishes are also an option.
Special Properties
Some finishes contain UV blockers, resist mold growth, or provide a rust-inhibiting primer in one product. Useful for outdoor furniture.
Sheen Level
Satin or semi-gloss finishes hide imperfections well and hold up better outside than glossy surfaces which can yellow over time.
Once you select the coating, prepare it according to manufacturer’s directions, including mixing multiple components for 2-part finishes. Never use indoor paints outside.
Priming and Painting the Furniture
With the right primer and paint, you can give your outdoor metal furniture a brand new look with any color you choose.
Apply Rust-Inhibiting Primer
Use a primer specifically made for metal that inhibits rust. Cover all surfaces evenly and let dry per product instructions.
Use Exterior-Grade Paint
Apply two coats of outdoor acrylic latex paint in your desired color according to label directions. Allow proper drying time between coats.
Spray Paint Smaller Areas
For smaller surfaces like hardware and embellishments, use a spray paint made for metal to avoid brush strokes. Several light coats work better than one heavy coat.
Work in a Well-Ventilated Area
Paint outdoors if possible. If working indoors, keep the area well-ventilated to allow fumes to dissipate. Wear a respirator when spraying paint.
Thorough priming and painting provides a durable and protective finish that keeps your outdoor metal furniture looking vibrant.
Applying a Clear Topcoat
Adding a clear topcoat over painted metal furniture gives it an extra layer of defense against the outdoor elements.
Choose a Fast-Drying, Oil-Based Topcoat
Look for an oil-based enamel, urethane, or epoxy topcoat that dries quickly. Water-based versions tend to stay tacky longer in humid outdoor conditions.
Use a Paint Sprayer for Large Areas
An electric paint sprayer allows you to quickly and evenly apply the topcoat over large surface areas. Backbrush afterwards to smooth out drips or ridges.
Brush On Topcoat for Small Sections
For smaller areas like embellishments and hardware, use a high-quality natural bristle brush to carefully brush on the topcoat.
Apply Thin, Even Coats
Applying several thin, even coats of the topcoat allows for proper curing and provides the best protection. Lightly sand between coats.
The clear topcoat seals the painted metal surface underneath, providing a glossy finished look that really makes the colors “pop”.
Using an Epoxy Coating
For a super durable and decorative finish, an epoxy coating is the ultimate option for refinishing outdoor metal furniture.
Choose a 2-Part Outdoor Epoxy
Purchase an epoxy made for outdoor use that consists of a resin and a hardener that must be mixed prior to application.
Thoroughly Abrade the Surface
Use 100-grit sandpaper to scuff up the bare metal to help the epoxy bond properly. Wipe away any residue after sanding.
Apply in Thin, Even Layers
Carefully brush on thin coats according to directions, using a high-quality epoxy brush. Allow proper curing times between layers.
Enhance with Epoxy Pigments
Add colored epoxy pigments to create an opaque, candy-colored finish. Metallic pigments also available for a glittery look.
Apply a Clear Epoxy Topcoat
For an ultra glossy finish, apply two coats of clear epoxy topcoat after the colored layer fully cures.
Epoxy coatings are durable, decorative, and easy to clean, making them ideal for outdoor furniture.
Applying an Oil-Based Stain
Oil-based stains offer a way to refinish metal furniture with a protective finish that allows the natural metal grain and patina to show through.
Use a Rust-Inhibiting Stain
Choose an oil-based stain that contains a rust inhibitor to protect outdoor metal furniture from corrosion.
Apply With a Clean Cloth
Dip a clean lint-free rag into the stain and wipe it directly onto the metal using smooth, with-the-grain strokes.
Let the Stain Penetrate
Allow the stain 5-10 minutes to fully penetrate and react with the metal before wiping away any excess.
Apply Additional Coats
For a darker shade, apply additional coats of stain after the previous application dries, usually 24-48 hours.
Add a Clear Topcoat
Once the stain is dry, apply a clear outdoor polyurethane topcoat to protect the finish.
Oil-based stains allow the unique look of the metal to show through while providing protection from the elements.
Securing Loose Joints and Hardware
Once the refinishing is complete, take time to check and repair any loose joints, fittings, or hardware before reassembling the furniture.
Reglue Loose Joints
Remove old glue and re-glue any loose joints using a waterproof epoxy or polyurethane glue. Clamp tightly until set.
Replace Broken Hardware
Swap out any missing or broken screws, bolts, handles, wheels, or other hardware for new matching pieces.
Tighten Loose Hardware
Using the correct screwdriver, wrench, or pliers, firmly tighten any screws, bolts, or fittings that wiggle or are loose.
Add Missing Fasteners
Look for any missing screws or other fasteners needed to properly secure parts of the furniture and replace.
This finishing step helps ensure that the furniture will remain sturdy, stable, and safely usable after refurbishing.
Protecting and Maintaining the Finish
Proper care and maintenance will keep your refinished outdoor metal furniture looking like new for years to come.
Inspect Frequently
Check the furniture every few months for any new scratches, dings, cracked paint, or rust spots needing touch up. Address these right away.
Wipe Down Regularly
Use a soft, damp cloth to gently wipe down the furniture every week or two to remove dirt, debris, bird droppings, etc. before they have a chance to stain.
Cover When Not in Use
Use weatherproof covers or store the furniture indoors when not in use for extended periods to protect the finish.
Apply Touch Up Coats
If the finish starts looking dull, lightly sand and apply a fresh topcoat to renew the protective layer.
With regular inspection and care, your newly refinished outdoor metal furniture will provide beauty, comfort, and functionality outside for years of enjoyment.
