Factors That Affect How Long Walnut Lasts Outside

The climate is one of the biggest factors that affect how long walnuts last outside. If you live in an area with a lot of sun and heat, your walnut furniture will likely not last as long as it would in a cooler climate. The same is true if you live in an area that experiences a lot of rain or snow. All of these elements can speed up the deterioration process.

Other factors include:

How Well the Furniture Is Made

Walnut wood is a strong and durable hardwood, but it is important to note that how well the furniture is made will affect how long it lasts. Buying cheap, poorly made walnut furniture will not last as long as high-quality, well-made furniture.

The Type of Finish on Your Furniture

The type of finish on the furniture also affects its longevity. A high-quality finish will protect the furniture from the elements and help it last longer.

If you have a piece of walnut furniture that’s unfinished or has a natural finish, it won’t last as long as one that’s been stained or painted. This is because finishes provide an extra layer of protection against the elements.

How You Care for the Furniture

Here are some tips on how to protect your walnut furniture from the elements:

Keep the Furniture Clean

Unlike other woods, walnut is very easy to clean. You can simply use a damp cloth to wipe down the furniture and remove any dirt or dust.

Pro tip:

When cleaning, use a mild soap and water solution. Avoid using harsh chemicals or abrasive cleaners as they can damage the finish.

Keeping the furniture clean is important because dirt and dust can damage the finish and make it more susceptible to damage from the elements.

Protect the Furniture from the Elements

When not in use, protecting your walnut furniture from the elements is important.

  • If you have outdoor furniture, you can buy covers to protect it from the sun, rain, and snow.
  • If you have indoor furniture, keep it away from windows where the sun can damage the finish.
  • Also, avoid placing it near heaters or fireplaces, as the heat can cause the wood to dry out and crack.

Don’t Leave the Furniture Outside in Extreme Weather

While walnut is a durable hardwood, it’s important to avoid leaving the furniture outside in extreme weather conditions. This includes periods of extremely cold or hot weather. If you must leave the furniture outside, ensure it’s in a shaded area to protect it from direct sunlight.

Use Furniture Covers

If you’re going to be away from home for an extended period, it’s a good idea to use furniture covers. This will protect the furniture from the elements and help it last longer.

Use Food-Safe Finishers

If you’re using the furniture when eating, it is possible to accidentally drop food or spill drinks on it. You can use a food-safe finish to protect the finish and make it food-safe. This type of finish is designed to resist staining and damage from food and liquids.

Use food-grade mineral oil to rehydrate your wood without leaving an oily film on the surface. The drawback of this kind of oil is how much upkeep is necessary to maintain the aesthetic appeal of this non-toxic wood finish.

Taking proper care of your walnut furniture can extend its lifespan and keep it looking beautiful for many years.

Ways To Protect Walnut Wood from Weather

When finishing walnut, proper surface preparation is important. The wood should first have its surface properly sanded. You can do this task by hand using a hand block or a portable, oscillating tool with a sanding attachment.

Woodworkers Source advises hand-sanding the job with a folded piece of 180-grit sandpaper after the initial sanding. Whenever sanding, always sand parallel to the grain.

This eliminates minute cross-grain scratches or swirls that are difficult to see now but will become noticeable in the future if they are not removed. You can either continue with the finishing or add your preferred stain after the last sanding.

After the stain has been applied and has had time to dry, you can apply your chosen topcoat. A few coats of a clear finish will help protect the walnut wood from weathering. You can also add a colored finish if you want to change the look of the wood.

Applying a topcoat is important because it will help protect the wood from UV light, moisture, and temperature changes. It’s important to reapply the topcoat every few years to keep the furniture looking its best.

Walnut is a beautiful hardwood that can add a touch of elegance to any home. However, it’s important to take proper care of walnut furniture to prevent damage from the elements. Following these tips can keep your walnut furniture looking beautiful for many years.

Can Walnut Wood Get Wet?

Class 3 durability and hardness make walnut wood resistant to water and water drops. As a result, walnut wood withstands shrinkage, warping, rotting, and other disasters reasonably well when exposed to water.

However, a good finish is needed because there is always a chance that wood will decay or work. You may increase walnut wood’s water resistance if you treat it appropriately. In this way, problems can be avoided.

Water and other drinks can potentially damage walnut wood because they can cause staining, warping, or discoloration. If you spill something on the wood, wipe it up immediately to avoid any potential damage.

It’s important to keep in mind that walnut is not waterproof, so you should never leave them outdoors in direct sunlight or in the rain. Additionally, you should never submerge walnut furniture in water because this can cause the wood to swell and warp.

If you take proper care of your walnut furniture, it can last for many years. However, it’s important to keep in mind that walnut is not as weather-resistant as other hardwoods, so you should take care to protect them from the elements.

How to Treat Walnut Wood for Outdoor Use

Now that you know how to take care of walnut wood, you may be wondering if it’s possible to treat it for outdoor use.

It is possible to treat walnut wood for outdoor use, but it’s important to keep in mind that the process is not reversible. Once you treat the wood, it will no longer be suitable for indoor use.

Treating walnut wood for outdoor use involves the following:

Applying Wood Sealers

Wood sealers are one of the most common and sure ways to treat wood for outdoor use. They work by creating a barrier between the wood and the elements, which helps to protect the wood from damage.

There are two types of wood sealers: water-based and oil-based. Water-based sealers are easier to apply and clean up but don’t last as long as oil-based sealers. Oil-based sealers provide better protection against the elements but are more difficult to apply and clean up.

Applying Oil Finishes

You may be wondering how individuals waterproofed wood before plastic-based sealers were introduced. The explanation is that they would apply various oil finishes to outdoor wood. Giving your wood one of these hand-rubbed oil finishes isn’t that difficult, and they have the added benefit of making the wood seem nice.

The two most common types of oil are used to finish wood.

  1. Linseed is produced by the flax plant.
  2. Tung oil is obtained from the tung tree.

It’s important to read the instructions on the product label before you begin because each product is different and should be used according to the manufacturer’s instructions.

Once you’ve applied the sealer or topcoat, you should allow the wood to dry completely before using it outdoors. This process can take up to 24 hours, so be sure to plan.

Final Thoughts

Walnut wood is durable and can last many years if properly cared for. However, it’s important to keep in mind that walnut is not as weather-resistant as other hardwoods. If you take the time to treat your walnut furniture for outdoor use, you can enjoy it for many years to come.
