Why do you need to learn how to treat untreated wood for outdoor use? Can’t you use the untreated wood like that? Well, you can, but several risks are usually associated with it. The primary issue related to the untreated wood is the chances of rotting; plus, you also have to deal with ultimately weather damage. Untreated wood would be completely exposed to sun and water, making the decay and damage process goes faster. 

You see, untreated wood is like a fortress without any guard. When you put it outside, it will take the most severe beating from natural elements, such as water and moisture and UV rays. Without any barrier between the wood and those elements, the wood would ‘lose the battle’. Rest assured that it would rot and decay fast. However, suppose you treat it by applying particular layers of substances. In that case, you prolong its lifecycle, so it doesn’t rot (or damage) quickly. 

How to Treat the Wood

So, how to treat untreated wood for outdoor use properly? The first thing you need to do is to sand the wood down. Use the wood sander to create a smooth finish. It will make the process go easier and faster to work.

  • Use the Sealer

Wood sealer is crucial, especially if you want to protect the wood from any elements. There are many outdoor sealers to use in hardware stores or home improvement stores. If you are more convenient buying it online, feel free to do it. Keep an eye for ‘water sealer’ on the label because this kind of sealer often comes with such a label. If you have any doubt, consult the store clerks. 

The wood sealer would cover and protect the wood on the exterior part to protect it from mildew, moisture, and the sun’s UV rays. Since wood is a natural element, you want to make sure that the centre is dry so it has a long lifecycle. 

  • Clear Coats

The clear coat is almost the same as the wood sealer. However, the clear coat can deliver a better (aesthetic) finish. Some of them are created for both outdoor and indoor use. The aim of applying it is to protect the wood from water and UV sunlight. The clear coat will make your wood glossy. Not all homeowners want to look, but the wood itself has a more sophisticated and sleeker appearance. 

The greatest thing about the clear coat is that it still allows the wood to expand and contract naturally, going along with the changes in temperatures and seasons. Even when you apply several layers of the coat, the wood would be just fine, and it would stay protected for quite a long time, making your work less complicated. You don’t have to apply whenever the season changes. 

  • Epoxy Resin

One of the steps in treating untreated wood for outdoor use is to use epoxy resin, which is a substance that can form a water resistance layer. If you want to protect the wood from any water damage, epoxy resin is a must. However, this one doesn’t have strong UV sunlight protection. The best thing you can do is mix it with a wood sealer having solid UV protection. Apply the sealer first and then the epoxy resin. Another downside of this substance is that it takes a long time for proper application, especially if you mix it up with other substances or layers. 

  • Outdoor Paint

The paint can be used to treat the outdoor wood. After all, there are special paints for outdoor use these days to provide extra coverage and extra protection. The great thing about the colour is that you can improve the visual appeal while providing the protection you want. Plus, different colours can lead to different outcomes, and you can be creative with them!

  • Wood Oils

Although the oil can provide extra protection against water damage, the level of strength and ability may not be as high as other substances. But it’s still good to protect the wood against moisture and water. There are also oil products that can prevent UV damage, but not all oils would have this feature. Oils are pretty standard for boats, delivering a glossy finish that makes them look luxurious and ‘expensive’. You can also apply the oils to your outdoor wood. 


Q: Are these products expensive?

A: Not really. Some products have standard pricing, while others can be premium. It usually depends on the length of coverage, and the more expensive products can protect the wood for longer times. Just pick the products that meet your budget. 

Q: So, what is the best product?

A: It depends on your needs and preferences. There is no uniform answer for different requirements or wood types. Do your task related to performing research. 

Q: Can I use one product only, or do I have to use a combination of them?

A: Again, it depends on your needs. If you think that one product can provide all the protection you need, then be my guest. But if you believe that several combinations of products can give the best result, then do it. 

Q: How do I know that one product is the best for me compared to the others?

A: This is why you need to perform thorough research. Take your time to understand what you want from the outdoor wood. Only by doing this can you decide on the best product that suits your needs. 

Final Words

As you can see, there are different options that you can have to treat the outdoor wood. Be sure of what you want to gain from the activity and determine your budget. You can begin the project after you understand how to treat untreated lumber for outdoor use properly.
