Using untreated wood for outdoor use is more cost-effective since this kind of wood is typically and mostly cheaper than treated wood.
However, preparing the wood for the fi takes longer, especially when you use it outside.
Can You Treat Wood for Outdoor Use?
Without the right treatment, untreated wood will age quickly outside due to the general weathering. It is more prone to fungi and rot when not properly treated.
One of the best ways to treat untreated wood is using a sealer. A water sealer is a great option since it contains both chemicals and water that will protect the wood from UV and mildew.
Using a combination of linseed oil and tung oil also works well for protecting untreated wood outside.
You must mix one part of each oil type, one part of mineral, and one part of polyurethane. Apply two coats of the solution and finish by sanding it with sandpaper.
Untreated wood can also be painted with the waterproof-type one, but if you want to keep its original look, go with a sealant instead.
Best Untreated Wood for Outdoor Use
Choosing the best-untreated wood means that you will at least have the right type of wood to resist some insects and the natural elements outside.
It doesn’t mean that you will have the wood outside forever because whatever type of wood will last for a certain amount of time, whatever it is.
Redwood is one of the best options for outdoor use. It has a reddish color and naturally occurring chemicals that act as protection from the outdoor natural elements.
However, this type of wood is rare due to protection from regulations on wood trees. If you need the kind of wood widely available, go with cedar.
It is resistant to moisture and insects and has a unique aromatic smell other types of wood don’t. Cypress is another wood option for outdoor use since it is resistant to insects and decay.
Its structure is also stable enough to use for various outdoor projects.
The best option for untreated wood depends on your need and your budget. It also depends on where you live and how the weather is. You are the one who can decide which type of untreated wood is best for your outdoor use.
How Long Does Untreated Wood Last Outside?
Many factors will influence how long untreated wood lasts outside, so there is no clear answer.
One thing for sure is that no matter how good untreated wood is treated, it will slowly get damaged.
Some things to consider to determine how long your untreated wood will last are the extreme weather conditions where you live, the type of wood used, the geographical location of your house, and the type of wood used.
Living in a sunny or shaded area also impacts wood lifespan. How the wood is treated, painted, or sealed will add to or decrease the lifespan.
So, if you want your wood to last longer outside, you must ensure you have the best location and preparation.
How to Seal Untreated Wood for Outdoor Use
Sealing untreated wood protects it from the humidity of the weather and insects. Although sooner or later, the wood will rot, you can at least add its lifespan by applying a water sealer to repel moisture.
The untreated wood has to be cleaned and sanded before applying a water sealer.
Cleaning the wood can be done just by using soap and water. Use 250-grit sandpaper to smoothen the surface and remove debris and dust from sanding before applying a water sealer.
Use a paintbrush to apply the sealer, and you can apply two coats if necessary.
How Do You Make Wood More Rot Resistant?
Using the best wood type that is naturally decay-resistant such as redwood and cedar, will help to prevent the wood from rotting.
However, since a certain type of wood, like redwood, is expensive and hard to find due to some regulations, preserving the wood you choose with chemical preservatives can be a solution.
To keep the beauty of the wood grain, go with a clear preservative like pentachlorophenol. This chemical preservative will not change the wood color; later, your wood can still be painted.
If you use Creosote, your wood color will turn dark brown and can’t be painted later. To protect your untreated wood, you shouldn’t brush it with preservatives but soak it.
It will provide the best protection to make its lifespan longer.
Does Painting Wood Prevent Rot?
Painting does prevent the wood from rotting as long as you pick the one for exterior use. Painting provides a protective coating for the wood, so it doesn’t get direct exposure to UV and humidity.
Not only will paint protect your wood from moisture, but it will also enhance its appeal.
However, since you are painting with untreated wood for outdoor use, some things have to be considered, including the preparation made and the type of paint used.
These will highly influence the paint’s result and effectiveness in protecting the wood.
Painting wood can help add to the lifespan of your outdoor furniture while giving it a beautiful look. You can add some coats of paint for more protection and prevent it from chipping easier.
How To Treat Untreated Wood for Ground Contact
Not only moisture and insects, but ground contact is also the culprit of rotten wood. The most common way to protect the wood from ground contact is by soaking the wood part in a preservative and painting it.
This method is easy and effective as it can also be used for an untreated type of wood. Surely your wood will still rot even after well preserved, but at least you add its lifespan before the time comes.
