Why Treat Pallet Wood for Outdoor Use?
Treating pallet wood for outdoor use is important to prevent them from rotting and to protect the wood from environmental elements such as moisture, UV rays, and insect attacks.
By treating pallet woods you’ll be able to make them safe from bacteria, mold, chemicals, and other harmful substances.
Nowadays, pallet wood can be used literally for anything.
Chairs, planters, tables, bookshelves, porches, patio furniture, flower boxes, wooden fences, and many other woodworks and furniture can be made by using pallet wood.
This is because they are affordable and easy to repair. In order to make them safe from environmental elements, you need to treat pallet wood properly.
Plus, you can increase the lifetime and durability of pallet wood by treating it.
Never leave pallet wood furniture or woodwork outdoors without treating it because the wood will begin to rot so quickly as soon as the moisture went inside of the wood through the fibers.
Once the wood starts to rot, it will get an unpleasant appearance. Restoration is also difficult if things went worse.
Plus, woods will discolor when they are exposed to sunlight for so long because of the harmful UV rays.
Treating helps to prevent wood discoloration and keeps them so long fresh as new.
Treating sealants and stain products have anti-UV agents that absorb UV light by avoiding them from entering the wooden surface.
Treating protects wood from cracking and splitting upon temperature variations and humidity changes.
Sealing and staining tolerate environmental impacts on wood pallets and protect the wood while enhancing the wood’s appearance.
In a summary, here’s why you should treat pallet wood for outdoor use,
- To prevent pallet wood from rotting
- Protect pallet wood from water damages
- Protect pallet wood from UV light
- Protect from insect attacks
- Protect from temperature variations
- Prevent wood discolorations
- Keep pallet wood from cracking and splitting
- To enhance the wood appearance

So, let’s find out what sealants and stain products you can use to treat pallet wood for outdoor use.
What Can You Use To Treat Pallet Wood For Outdoor Use?
You can use sealant or stain to treat pallet wood for outdoor use. Apply sealant or stain all over the pallet wood and let it dry before keeping it outside for best use.
Always read the manufacturer’s instructions before using any product on pallet wood to apply without making any mistakes.
Here’re the best products that you can use to treat pallet wood for outdoor use.
- Epoxy finish
- Oil finish (Tung oil, Linseed oil, Danish oil, Hemp oil)
All the above wood-treating products help pallet wood to get protected from environmental elements such as moisture, UV light, insect attacks, and more.
So, let’s discuss each of the above products separately to see how they work on pallet wood.
Epoxy Finish on Pallet Wood
The epoxy finish provides waterproofing ability to pallet wood and prevents pallet wood furniture and woodwork from water damage.
Epoxy finish is consisting of epoxy resin and hardener. Mix both resin and hardener well in a container before applying to the pallet wood.
After mixing pour and apply epoxy finish on an entire wooden surface without missing any spot. Use a bristle brush to apply on edges and tough corners.
Epoxy resin doesn’t give much protection from UV light. Therefore, if you are going to place pallet woods in an area that expose to direct sunlight, better not to use an epoxy finish.
A single coat of epoxy finish is enough to treat pallet wood for outdoor use.
Water particles cannot penetrate through the epoxy layer and damage the wood. epoxy finish protects wood from rotting.

How To Treat Pallet Wood for Outdoor Use?
Treating pallet wood for outdoor use is important to keep them protected from environmental elements, such as moisture, UV light, insect attacks, and harsh weather conditions.
Treating pallet wood will also help to improve their sheen by giving an attractive look to outdoor pallet furniture and woodwork.
Here’s the process of treating pallet wood for outdoor use.
- Select a safe pallet
- Clean and prepare the surface
- Sand the entire surface
- Treat the pallet
- Let the finish dry and cure
So, let’s discuss each of the above steps one by one to see how to treat pallet woods correctly for outdoor use.
1. Select a Safe Pallet
Before treating you need to have a good understanding of where pallet woods came from since they use in different industries.
Some of them can be so harmful and not in a good condition to be treated.
Some pallet woods were placed next to the trash cans and grew mold and habitat for rats and cockroaches. So, never use that kind of pallet wood for outdoor furniture even after treatment.
Get pallets from local used pallet dealers by knowing where they came from and how were they used.
Check if your pallets are marked with the letters “MB” stamped on them. MB means Methyl Bromide which is a harmful chemical.
That means Methyl Bromide has been used on your pallets as a pesticide.
Those MB-stamped pallets should not be used as outdoor furniture since they can be toxic to humans.
Check whether your pallets have stain rings that occurred due to chemicals.
Better to avoid those pallets for outdoor furniture since they can contain toxic chemical compounds even after treating the wood.
Follow the below table before treating any kind of pallet wood.
|Code In Pallet||Treatable or not|
|IPPC Logo||Not Sure|
|DB||Safe to treat|
|HT||Safe to treat|
|MB||Do not treat and use|
|EPAL||Safe to treat|
|EUR||Do not treat|
|Colored Pallet||Do not treat or use|
In summary, here’s how you should select a safe pallet for treatment.
- IPPC logo stamped pallets came from abroad and not sure whether they are safe to treat or not.
- DB stamped pallets (Debarked) are chemically free and safe to treat.
- HT stamped pallets (Heat treated) repel bugs without chemical treatments and are safe to treat.
- MB stamped pallets (Methyl Bromide) do not treat due to high toxicity.
- EPAL stamped pallets (European Pallet Association Logo) are debarked or heat treated and safe to treat.
- EUR stamped pallets are the old versions of EPAL and do not treat without the EPAL logo.
- Colored pallets are toxic and do not treat or used for outdoor projects.
DB, HT, and EPAL stamped pallet woods are good for treating. So, better to use only those pallet woods for outdoor woodworking projects.

2. Clean and Prepare the Surface
After selecting a safe pallet for treating before outdoor use, clean the entire wooden surface using a pressure washer.
Before treating you need to remove all the dust, dirt, grease, stain marks, and all other impurities from the pallet wood surface for better absorption of the treating compound.
Cleaning helps to treat pallet woods without making any mistakes and increases the durability of the wood.
After cleaning the wood properly, let it dry completely before moving to the next step.
3. Sand The Entire Surface
Once the pallet wood is completely dried, sand the entire surface with 220 grit sandpapers to eliminate surface randomness and make the surface ready to take the treating product.
Sand along the direction of the wood grain for better treatment and it helps to make the surface even and smooth.
After sanding, the pallet wood surface is easy to finish, and the coat has less tendency to crack or peel.
If your pallet wood has protruding nails, and screw heads, better to remove them before sanding to prevent your grinding tools from getting damaged.
Once you’re done with sanding, remove sawdust using a dust pipe or rag and prepare the surface for treating.
4. Treat The Pallet Wood
Now you can treat the pallet wood surface with epoxy finish, oil finish, paint, varnish, or stain. Apply the treating product along the direction of the wood grain for better absorbance.
Let the coats dry between coats.
Apply 2 – 3 coats to treat pallet wood for any kind of outdoor woodworking project.
Make sure to treat the pallet all over the surface without missing any spots. Use a paintbrush when treating.
If you’re using stain to treat pallet wood, better to apply wood conditioner first to control wood absorption rates and to avoid making wood stain mistakes.
Treat pallet woods in a well-ventilated area for proper drying and to avoid breathing harmful chemicals.
Once pallet woods are well treated, they are waterproof, UV resistant, and do not rot easily for a few years.

5. Let The Finish Dry and Cure
After treating pallet wood, let the finish dry and cure completely before using it for outdoor use.
Let treated coats dry and settle for at least 48 hours.
Curing time can be 2 – 3 days which varies on the treated product type and environmental humidity.
If you live in a humid area, this can take even more than a week. However proper drying and treating are a must to get a good protective coat over the wooden surface.
After drying and curing pallet wood will get its new look and now you can use it as outdoor furniture or woodwork since it has a good protective shield against environmental elements such as moisture, UV light, insect attacks, and more.
Drying and curing are essential for excellent treatment.
That’s it, Folks! Now you know how to treat pallet wood for outdoor use with simple treating steps.
Let’s answer some frequently asked questions about treating pallet wood.
Can Pallets Be Used for Outdoor Furniture?
