6 Essential Steps to Refinishing Teak Furniture Like a Pro

Refinishing teak furniture is one of the most rewarding ways to extend the life of a beautiful outdoor investment. Teak is a rich golden wood that instantly elevates any patio or deck design, and its naturally water-resistant oils make it one of the most durable options for outdoor use.

As a bonus, research shows that many homeowners are also turning to teak furniture as an environmentally friendly option. It’s highly sustainable and mostly grown in plantations specifically for timber production, which helps reduce the demand put on our natural forests.

However, like any other outdoor furniture, teak can suffer from wear and tear over time. The sun and rain will fade the wood’s color while dirt and grime build up on the surface.

If your teak furniture is looking a bit worse for wear, don’t despair. With a bit of elbow grease, you can refinish your teak furniture and restore it to its original beauty.

This guide will walk you through the teak furniture refinishing process, step by step – so you can maintain different pieces of teak furniture for years to come.

How to Tell If Your Furniture Is Actually Teak

Before starting any restoration work, it helps to confirm you’re working with real teak. Genuine teak has a golden to golden-brown color when new and a straight, tight wood grain. It has a naturally oily feel to the touch and a faint, pleasant smell from its natural oils.

When left outdoors without maintenance, real teak turns a silvery gray over time. This graying is purely cosmetic and does not affect the wood’s structural strength. If you press a fingernail into a gray area and find the wood beneath is still solid and dense, it’s a good sign the teak is in restorable condition.

What You’ll Need

Before refinishing teak furniture, you’ll need to gather all the necessary supplies. These items include:

• A garden hose
• A scrub brush and/or rag
• Sandpaper (80 to 120 grit for gray removal, 220 grit for finishing)
• Teak cleaning solution or homemade cleaner (see below)
• Teak wood filler (for cracks or damaged areas)
• Teak sealer (avoid teak oil products)
• Lint-free cloths for sealer application

You should also wear gloves, a dust mask, and protective eyewear while refinishing your teak furniture. This will help you avoid any accidents and protect your hands and eyes from the chemicals in the teak cleaning solution. A dust mask is especially important during sanding, as teak dust can cause skin and respiratory irritation.

Of course, if you use a professional restoration service, they’ll take care of all the refinishing for you. You won’t have to worry about any of the supplies or steps!

DIY Teak Cleaner Options

A commercial teak cleaning solution works well, but a simple homemade cleaner is just as effective for most jobs:

• Option 1: One cup of powdered oxygen bleach per gallon of warm water
• Option 2: One cup of white vinegar per gallon of warm water

Oxygen bleach is the stronger of the two and works well on mold, mildew, and embedded grime. Vinegar works well for lighter surface cleaning and as a post-sanding rinse to remove dust before sealing.

Avoid chlorine bleach entirely. It strips the natural color from teak, degrades the wood fibers over time, and can damage the surrounding environment if it runs off into your garden or lawn.

If you go with the oxygen bleach option, a few precautions are worth taking.

• Again, don’t forget to wear rubber gloves and eye protection during mixing and application, as the solution can irritate skin and eyes on contact.
• Work in a well-ventilated area and wear your dust mask while mixing to avoid breathing in the powder.
• Wet any nearby plants or grass before you start and rinse them again after you’re done to dilute any runoff.
• Keep children and pets off the furniture until it has been fully rinsed and dried.

Your Step-by-Step Guide to Refinishing Teak Furniture

Once your cleaning solution is ready, it’s time to start restoring your teak furniture. Here’s how to do it step by step.

Step 1: Thoroughly Clean the Teak Furniture

Before getting started, give your teak furniture a thorough cleaning. If you don’t remove the build-up of dirt and grime, it will be difficult to refinish the furniture and achieve a smooth, even finish.

Start by rinsing the furniture with a garden hose to remove loose debris. Then apply your teak cleaning solution to a soft-bristle brush and scrub the surface in sections, working with the grain. Pay close attention to the joints, undersides of slats, and any areas where mold or mildew has settled.

Once you’ve scrubbed the entire piece, rinse thoroughly with clean water to remove all soap or cleaning solution residue. Residue left on the surface can interfere with sanding and sealing later.

Avoid using a pressure washer on teak furniture. The high-pressure water strips the natural oils from the wood and can shred softer or already-damaged areas. A soft brush and hose give you far better control without risking additional damage.

After rinsing, allow the furniture to air dry completely before moving to the next step. Depending on weather conditions, this can take several hours to a full day.

Step 2: Replace or Repair Problems

Once the furniture is clean and dry, inspect it carefully for damage that needs addressing before sanding and sealing.

Teak is durable, but years of sun and moisture exposure can cause cracking, splitting, or soft spots. Check joints and hardware for looseness, and tighten any screws or bolts as needed.

For minor cracks and small damaged areas, apply an exterior wood filler rated for outdoor use. Use a putty knife or your fingers to press the filler into the damaged area and smooth it flush with the surrounding surface. Allow it to dry completely before sanding and sealing the wood.

For more significant damage, replacement is the better option. Source replacement slats or components in the correct size and wood type so they blend with the existing piece over time.

When replacing hardware, use screws specifically coated for outdoor use. Standard screws can corrode and stain the surrounding wood over time.

Step 3: Sand the Rough Gray Areas

After repairing any damage and allowing the filler or replacement pieces to settle, the next step is to sand the teak furniture.

Exposure to the sun and rain can cause the wood to gray and become rough to the touch. If you want your refinishing project to be successful, you’ll need to remove this outer layer of gray before moving on.

To sand the outer layer of gray, start with 80 to 100 grit sandpaper and work your way up to 120 grit once the gray is gone. Finish with 220 grit for a smooth, even surface that takes the sealer well. Avoid using a power sander, as these can be too aggressive and damage the wood.

Once you’ve sanded away the gray outer layer, you should see the original color of the teak wood. If the wood is still too rough, you can continue sanding with finer grit sandpaper until it’s smooth to the touch. Always sand in the direction of the grain to avoid leaving visible scratches in the finished surface.

After sanding, use a handheld vacuum or brush to remove dust from the furniture’s surface. Then, you should clean the wood and let it dry entirely before you move to the next step of refinishing teak furniture.

Step 4: Wash the Furniture Properly After Sanding

This step is easy to overlook but worth doing before applying any sealer. As mentioned, sanding leaves a fine layer of dust across the entire surface, and if that dust mixes with the sealer, it affects the finish quality and how well the product bonds to the wood.

Wipe the entire surface down with a clean rag dampened with a water and white vinegar solution. Then rinse gently with a garden hose and allow the furniture to dry completely before moving on.

Step 5: Protect the Teak Wood with a Sealer

With the furniture clean, repaired, sanded, and dust-free, it’s time to apply the sealer.

A teak sealer or protector creates a barrier against moisture, UV light, and the elements that cause graying and deterioration. Applied correctly and maintained regularly, it keeps the wood’s natural golden color and significantly extends the furniture’s lifespan.

A note on teak oil: We strongly advise against using any product labeled as teak oil. Despite marketing claims, most teak oil products are made from low-quality ingredients not sourced from real teak. They get absorbed by the wood, break down the natural oils already present, and over time cause cracking, splitting, and in some cases rot. A proper teak sealer or protector is always the right choice.

How to apply the sealer:

Pour a small amount of the sealer into a bowl and apply it using a lint-free cloth rather than a brush. Brushes tend to create runs and uneven pooling, especially on vertical surfaces and between slats. A lint-free cloth gives you direct control and works the product evenly into the wood surface.

Apply the sealer in the direction of the grain, working in sections. Cover the entire piece, including legs, undersides, and any hardware-adjacent areas where moisture tends to collect. Apply two coats for the best protection, allowing the first coat to dry fully before applying the second.

Follow the manufacturer’s instructions for dry time between coats and before exposing the furniture to rain or heavy use.

Step 6: Repeat Maintenance As Needed

Although refinishing teak furniture may seem like a lot of work, it’s important to repeat the process and general maintenance as needed.

Because the furniture lives outdoors year-round, it faces consistent exposure to UV light, moisture, and temperature changes that gradually wear down even the best sealer.

A full restoration like the one described in this guide is typically needed every one to two years for furniture in regular outdoor use. Between full refinishing sessions, a light cleaning and a fresh coat of sealer can extend the time between major treatments.

Keep an eye out for these signs that maintenance is due:

• Water soaking into the wood rather than beading on the surface
• The return of gray or dull coloring
• Mold or mildew reappearing after cleaning
• The wood feeling rough or dry to the touch

Staying ahead of these signs keeps the work manageable. A light sanding and a fresh coat of sealer on furniture that’s been maintained regularly takes a fraction of the time and effort of a full restoration on neglected pieces.

Again, if you’re not comfortable restoring your own teak furniture, a company that specializes in refinishing teak furniture can do it for you. Companies like ours know precisely how to refinish teak furniture properly and can get it done far more efficiently than a DIY approach.

Frequently Asked Questions About Refinishing Teak Furniture

You may still have some lingering concerns about restoring and refinishing teak furniture. If so, check out the answers to some of our most commonly asked questions below:

Do different types of teak furniture require different types of care? 

Yes. A teak chair might require slightly different maintenance than a table or bench. Here are some tips for maintaining different pieces.

Teak Chairs 

When caring for your teak seating arrangements, pay special attention to the armrests and legs of chairs. These spots are more prone to wear and tear and may require more regular cleaning, as well as more frequent oiling and resealing.

You’ll also want to check the joints and hardware of your teak chairs. Watch for signs of looseness or damage, and tighten screws and bolts as needed to preserve the chair’s integrity.

Teak Tables

Teak tabletops may require more frequent cleaning compared to other furniture pieces due to their larger surface area. Wipe your tabletop regularly with a damp cloth to remove dirt and spills, and avoid placing hot or wet items directly on the wood to prevent damage.

Just as you would with teak chairs, check the table’s structural integrity often and tighten any loose hardware. Also, make sure to keep your table on a level surface to prevent wobbling. 

Teak Benches 

Sand the seating surface occasionally to remove roughness or minor scratches as they build up. Applying a fresh coat of teak sealer after sanding protects the wood and maintains its smoothness.

Consider elevating the bench slightly or using protective pads to minimize ground moisture contact, especially if it stays outside year-round.

Teak Loungers

Teak loungers, also known as teak sun loungers or teak chaise lounges, require similar care to other types of teak furniture, but there are a few additional things to consider, such as regularly cleaning their cushions or testing their adjustable parts.

If your teak lounger is equipped with wheels for easy mobility, inspect them periodically to ensure they are rolling smoothly. Clean any dirt or debris from the wheels and lubricate them if necessary to maintain their functionality.

Why does teak wood turn gray in the first place?

Teak wood is naturally resistant to rot, mold, and mildew when cared for properly. However, over time, it can become gray and weathered-looking from exposure to sunlight and rain.

Although this doesn’t necessarily affect the strength or durability of the wood, it can be unsightly. Refinishing teak furniture is the best way to restore its original color.

How long does it take for teak wood to discolor?

The amount of time it takes for teak wood to discolor depends on its exposure to sunlight and rain. If the furniture is kept in a covered area, it will take longer to discolor than if left out in the open. In general, you can expect teak wood to start graying within 5 to 12 months if it’s not properly sealed and maintained. 

Can I paint or stain my teak furniture?

We recommend against painting or staining your teak furniture. It will not only hide the beauty of the teak wood, but it will also penetrate the seal coating. This will eventually lead to flaking, peeling, cracking, and other damage. Teak’s natural oils also make it difficult for paint and stain to adhere to the surface. 

Is it possible to change the color of my teak furniture?

Yes, when refinishing teak furniture, you can change its color. However, as mentioned, it’s not as simple as refinishing other types of wood furniture.

Without taking the proper precautions, you could end up damaging your furniture. If you’re set on changing the color of your furniture, we recommend working with a professional teak refinisher and restorer.

Can I use regular wood stain on teak furniture?

No, you should not use regular wood stains on teak furniture. Teak is a unique type of wood due to its high oil content. As a result, it needs to be stained with a specially formulated teak stain. Regular wood stains will not adhere to the surface and can cause significant damage.

Is vinegar good for cleaning outdoor teak furniture?

Yes, vinegar is a good option for cleaning outdoor teak furniture. To clean with vinegar, mix one part white vinegar with three parts water in a bucket. Use a soft brush or cloth to apply the mixture to the furniture’s surface and scrub away dirt and grime. Rinse the furniture with clean water when you’re finished.

What is the best time of year for refinishing teak furniture?

Because Southern California has such mild weather, you can refinish teak furniture pretty much any time of year. However, we recommend finding a time when rain is not in the forecast for at least 48 hours. You don’t want rainwater interfering with the refinishing process.

Why is my teak furniture almost black?

If your teak furniture has turned black, it’s likely due to extreme weathering and build-up. As mentioned, the sun’s UV rays can cause the wood to oxidize and change colors. Additionally, if your teak furniture is consistently exposed to moisture, it can encourage the growth of mold and mildew. This can also cause the wood to turn black.

How much does it cost to have professionals refinish teak furniture?

Prices for refinishing teak furniture vary depending on the size and condition of the furniture. In general, we estimate you can expect to pay 25% of the cost of a new piece of teak furniture. Getting your teak furniture professionally refinished is a much cheaper option than buying new furniture altogether.

Of course, some professional restoration teams may charge more or less than this. It’s always best to get a few estimates before making a decision.
