How to Waterproof Wicker Furniture for Outdoor Living in 2025

Imagine you are relaxing outside with coffee when suddenly the rain starts and your wicker chairs get wet. Knowing how to waterproof wicker furniture is essential if you want your outdoor area to look nice all year round. 

Water damage and fading can happen fast, but with the right techniques, you can protect your furniture. You are not the only one who wants to protect wicker furniture. In 2025, people care more about strong outdoor furniture.

Many people want to use their patio in any weather, which is why learning how to waterproof wicker furniture is so important. But first…

What Is Wicker Furniture?

You might see wicker furniture outside or inside your house. Some people think wicker is a kind of material. That is not true. Wicker means the way people weave fibers to make furniture. The weaving makes the furniture strong and nice to look at. You can tell it is wicker by the special woven patterns. These patterns make each piece strong and pretty.

Let’s look at the basics:

• Wicker is a weaving technique. It is not a material. It is how the fibers are woven to make things like chairs and tables.
• Natural wicker uses things like rattan, willow, or bamboo. These pieces look classic and feel warm. They need more care. Natural wicker can soak up water. You need to use a good wicker furniture sealant or a wicker protector spray if you want to keep it outside.
• Synthetic wicker is made from strong things like resin or polyethylene. This kind is made for outdoor use. It can handle rain, sun, and snow. It is much easier to clean and take care of. If you wonder, “Can I waterproof wicker?”—synthetic is best for outside.

Here is a quick look at the differences:

You will also see different weaving patterns, like basket weave or herringbone. These patterns do not just look cool. They also help make the furniture strong and better in bad weather. If you want to know how to weatherproof wicker furniture, knowing the type and weave helps you pick the right products and ways to do it.

So, before you look up how to waterproof wicker furniture, check what kind of wicker you have. This helps you pick the best way to protect your furniture. Then you can enjoy your outdoor space for a long time.

Does water damage wicker furniture?

If you leave your wicker chair outside overnight, the next morning, you’ll notice it feels damp and smells a bit musty. You wonder, “Can I waterproof wicker to stop this from happening?” 

You’re not alone. Many people face this problem, especially if they want to know how to waterproof wicker furniture for outdoor living.

Water can cause big problems for both natural and synthetic wicker. Here’s what you need to watch out for:

Mold and Mildew Growth

Wicker furniture traps moisture deep inside the weave. When water sits in those tiny spaces, mold and mildew start to grow. This makes your furniture smell bad and look dirty. Mold can even make the surface feel slimy or sticky.

Warping and Cracking

Natural wicker, like rattan or bamboo, soaks up water easily. When the fibers get wet, they swell. As they dry, they shrink back. This constant change can make the wicker warp or crack. Over time, your chair might lose its shape or even break.

Weakening of Materials

Water doesn’t just sit on the surface. It can sneak inside and damage the fibers from within. This makes the furniture weak and less sturdy. Synthetic wicker handles water better, but it can still get damaged if water seeps into the frame or if the protective coating wears off.

Tip: Regular cleaning and using a good wicker furniture sealant or a wicker protector spray can help stop these problems before they start.

Rust and Frame Damage

Many wicker pieces have metal frames. If water gets inside, the frame can rust. This makes the whole chair wobbly and unsafe.

If you want to know how to waterproof wicker furniture, you need to protect it from all these issues. Using products like marine varnish, oil-based paint, or a spray sealant creates a barrier that keeps water out. For extra protection, choose mold-resistant cushions and cover your furniture when not in use.

Learning how to weatherproof wicker furniture is the best way to keep your outdoor space looking great.

How to Waterproof Wicker Furniture

Ready to make your outdoor space last through every season? Let’s walk through how to waterproof wicker furniture step by step. You don’t need to be a pro—just follow these simple instructions and you’ll keep your chairs and tables looking great, rain or shine.

1. Clean thoroughly

Start with a clean surface. Dirt and dust can stop sealants from sticking well. Here’s how you do it:

1. Use a vacuum with a brush attachment or a dry paintbrush to remove loose dirt from the weave.
2. Mix a little mild soap with water. Dip a soft cloth or sponge in the solution and gently wipe the wicker. For tight spots, use a soft-bristle brush.
3. Rinse with clean water, but don’t soak the furniture. Too much water can weaken natural fibers.
4. Pat dry with a lint-free cloth. Let the furniture air dry completely before moving to the next step.

Tip: Clean small sections at a time and make sure everything is dry before you continue. This helps prevent mold and keeps the wicker strong.

2. Repair any damages

Check your furniture for any broken or loose pieces. Fixing these now will help the waterproofing last longer.

• For natural wicker, glue loose ends back in place with wood glue. Let it dry fully.
• For synthetic wicker, use a repair kit or replace broken strips if needed.
• Tighten any screws or bolts on the frame.

If you skip this step, water can sneak into cracks and cause more damage later.

3. Sand lightly

Sanding helps the sealant stick better and smooths out rough spots.

1. Use fine-grit sandpaper (220 grit works well).
2. Gently sand the surface, following the direction of the weave.
3. Wipe away dust with a dry cloth.

Don’t sand too hard, especially on natural wicker. You just want to rough up the surface a little.

4. Apply waterproof sealant

Now comes the most important part of how to waterproof wicker furniture. You have a few choices for sealants:

• Marine varnish (spar varnish): Great for outdoor use. It’s flexible and protects against water and sun.
• Spar urethane: Similar to marine varnish, but dries a bit harder. Good for high-traffic areas.
• Tung oil: Gives a natural look and hard finish, but takes longer to cure.
• Spray polyurethane: Easy to use, but not as UV-resistant as varnish.
• Oil-based paint: Adds color and waterproofing, but changes the look of natural wicker.
• Wicker furniture sealant or wicker protector spray: These are made just for wicker and are easy to apply.

For natural wicker, choose marine varnish, spar urethane, or tung oil. These soak into the fibers and do the job of waterproofing wood for outdoors. For synthetic wicker, a spray polyurethane or a wicker protector spray works well. Synthetic materials don’t absorb as much, so you just need a good surface coating.

How to apply:

1. Use a brush or sprayer to put on a thin, even coat. Make sure you get into all the nooks and crannies.
2. Let the first coat dry as the product label says—usually 24 to 48 hours.
3. For best results, lightly sand between coats to help the next layer stick.

Tip: Always work in a well-ventilated area. Wear gloves to protect your hands.

5. Dry and cure

Let your furniture dry and cure fully. This step is key for long-lasting waterproofing.

• Most sealants need 24 to 48 hours to dry between coats.
• After the final coat, let the furniture cure for at least three days before using it.
• If you use tung oil or another natural oil, curing can take up to a week, depending on the weather.

Don’t rush this step. If you use your furniture too soon, the finish might not protect as well.

6. Reapply a second layer

One coat is good, but two or three coats are even better. Each layer adds more protection.

1. After the first coat dries, lightly sand again.
2. Wipe away dust.
3. Apply the next coat just like before.
4. Let each coat dry fully before adding another.

Most experts recommend at least two coats for outdoor furniture. If your patio gets a lot of rain or sun, you might want to add a third coat.

Tip: For extra shine and water resistance, you can buff the surface with car wax after the sealant cures.

Natural vs. Synthetic Wicker: What’s Different?

If you want to know how to weatherproof wicker furniture, always check what type you have. The right products and steps make all the difference.

Learning how to waterproof wicker furniture is the best way to protect your investment. With a little effort, you’ll enjoy your outdoor space for years, no matter the weather.

Extra Protection Tips

You want your outdoor space to stay beautiful, no matter what the weather brings. Here are some extra steps you can take to keep your wicker furniture looking great all year.

1. Use furniture covers

You can’t always predict the weather, but you can protect your furniture. High-quality covers shield your wicker from rain, snow, and harsh sun. Look for covers made from waterproof materials with UV protection. 

Make sure they fit snugly to keep out moisture and dirt. Breathable covers help prevent mold and mildew. Secure them with straps or ties, so they stay put on windy days. Even when you store your furniture indoors, a cover adds another layer of defense.

• Covers block UV rays, rain, and bird droppings.
• They keep dust and dirt away, especially if you live in a windy area.
• Using covers saves you money on repairs and keeps your furniture looking new.

2. Get weather-resistant cushions

Choose cushions made for outdoor use. These resist water and dry quickly. Weather-resistant fabrics also block UV rays, so colors stay bright. You won’t have to worry about mold or fading. Swap out old cushions for new ones if you notice wear.

3. Avoid direct sunlight

Sunlight can fade and weaken your wicker. UV rays break down dyes and materials, causing color loss and brittleness. Place your furniture in a shaded spot, or use an umbrella or awning. This simple step helps your furniture last longer and keeps it looking fresh.

4. Clean regularly

Dust, dirt, and moisture can sneak into the weave. Regular cleaning stops buildup that can cause damage. Use a soft brush or cloth and a little soapy water. Don’t soak natural wicker but you can just wipe it gently. 

For synthetic wicker, you can use a bit more water. Set reminders to clean your furniture, so you never forget. Clean covers too, so they keep working well.

5. Bring indoors during harsh season

When winter or heavy storms hit, bring your wicker furniture inside. Many people find that moving their outdoor pieces indoors improves air quality and keeps the furniture in top shape. 

Eco-friendly wicker doesn’t release harmful chemicals, so it’s safe for your home. Indoor storage also means less cleaning and fewer repairs. You get more years out of your investment, and your furniture stays comfortable and stylish.

Tip: These extra steps, along with learning how to waterproof wicker furniture, give you peace of mind and a patio that always feels inviting.
