You can use a wooden pallet to transform your outdoor facade, but have you considered treating it before using it? Untreated wood pallets decay quickly, so how would you extend their lifespan?
To end your dilemma, our resident woodworkers will share how to treat pallet wood for outdoor use, including the ideal finishes for your pallet.
Reasons To Treat Pallet Wood for Outdoor Use
Untreated pallets are not waterproof and can swell, bend, soften, and damage. It is also susceptible to fungus, pests, and bacteria. Also, if your pallet wood remains untreated, the wood tends to crack and split because of harsh weather conditions.
So, wooden pallets should be treated regardless if you acquired recycled, remanufactured, or new pallets; otherwise, they won’t last long.
As durable and reliable for most woodworkers, homeowners, and DIYers, pallet woods are versatile and have endless possibilities, including DIY projects.
These woods are used by many shipping lines to carry heavy containers, so wooden pallets are durable enough if you are looking for heavy-duty timber for your garden and outdoor accessories.
Indeed, treating pallet wood like any other wood can prevent and delay the decaying stage. It can also prevent discolorations and insect attacks and has protective layers from water and extreme heat.
Ultimately, giving your pallet a proper wood finish results in a longer lifespan and makes your wood project more appealing.
Products You Can Use To Treat Pallet Wood for Outdoor Use
1. Epoxy Finish
The epoxy finish offers a solid finish to your pallet and good resistance to water and moisture. Although it provides minimum protective layers from ultraviolet radiation, you can still apply multiple coats of varnish over the epoxy finish.
2. Oil Finish
Tung Oil
Commonly known as China wood oil, tung oil finish provides better water resistance from within and beyond your pallet wood. However, you must wait long before the tung oil dries completely.
Before using this finish, we suggest knowing the advantages and disadvantages of tung oil. So, read next!
Linseed Oil
From the seeds of flax plants, linseed oil is considered a natural oil that offers a protective coat once dried completely. But, a pallet of wood with a linseed oil finish, similar to tung oil, cannot be exposed directly to heat or UV radiation.
Danish Oil
Most woodworkers prefer danish oil to linseed oil finishes because the former offers excellent resistance to water, moisture, chemicals, and damages that may occur once the pallets are used.
Unlike other finishes, danish oil dries quickly and provides a better sheen on your pallet wood. The key to achieving better results is to ensure that your pallets are bare, or you must remove any old finish, if any.
For more info, here’s a guide on using Danish oil.
Hemp Oil
Another oil finish we have is hemp oil, a natural sealer that protects your wooden pallets from damage due to water and weather.
Also, hemp oil is a good preservative and toxic-free, making it one of our top choice among oil finishes. You can use it for your indoor and outdoor wooden surfaces.
3. Paint
Paint is one of our most convenient finishes for pallets. With a smooth and vibrant look, this finish gives protection from outdoor elements such as rain, sunlight, snow, and moisture. We recommend using paint with two layers of a top coat like lacquer for better results.
4. Varnish
Varnish on your pallet wood should be a marine spar varnish that can hold off moisture, water, chemicals, and UV radiation. Marine spar varnish combines resins, solvents, and chemicals for more durability.
This type of varnish is ideal for exterior use, such as on your wooden pallet, because marine spar varnish is used for boats and other structures exposed directly to water. But it also provides resistance against the sun.
5. Stain
Pallets come in different colors and wood grain patterns, so you can opt for a stain finish. Stain offers protection for your wooden pallets resulting in an attractive appearance.
However, before applying stain, you must pre-stain your wooden pallet. To treat pallet wood, conditioning is necessary if you want your wood stains not to produce blotches or streaks. This is for excellent protection as well.
Steps To Treat Pallet Wood for Outdoor Use
After learning about the finishes you can use, we have here the basic steps on how to treat pallet wood for outdoor use. You can also apply these procedures for your interior wooden pallet.
Step #1: Choose a pallet
The first thing you must do is look for the ideal size and color of your pallet wood. After carefully choosing your pallet, you must check the labels, stamps, or markings on the sides of the pallet.
The labels give you information about the pallet manufacturers and if it is treated or not. It should have the logo, country of origin, and registration number.
Including the warehouse’s International Plant Protection Convention or IPPC logo, the origin is mandatory. Also, it should indicate the treatment code with at least two letters or four-letter code, as it will be the basis for whether the pallet is treated or not.
Here are the stamped pallet codes we have listed for choosing a safe pallet wood:
- DB (Debarked) is a code used to indicate that the pallet wood is safe and is untreated after removing the tree’s bark using a cutting tool.
- HT (Heat treated) or KD (Kiln Dried) indicates that the pallet has been heat-treated using a kiln for 30 minutes to remove the insects and maintain the correct moisture content of your wood—also, a safe pallet to use.
- MB (Methyl Bromide) code warns that the pallet has been treated using toxic chemicals, so avoid using it. There are many listed health hazards of MB because of the chemicals used for treating wood.
- Colored pallets may seem appealing and enticing, but the more visible the color, the more hazardous it is. So, avoid using it like MB.
- EUR is also banned from the market because research found it unsafe to use in the household. Therefore, EPAL replaced it in 1991.
- EPAL (European Pallet Association Logo) is a code that indicates that the pallet has been debarked and heat-treated, making it safe to use.
Therefore, you should look for DB, HT, and EPAL labels and avoid the MB, EUR, and colored pallets for better results and a pallet project.
Step #2: Prep The Surface
After choosing the safe pallet wood, prepare the surface using a pressure washer. This method is ideal for pallet wood cleaning to remove the impurities thoroughly on the surface, such as grease, dust, wood stain marks, and dirt.
You must remember that a clean wood surface will have a good absorption of the finish you desire. After cleaning, let the pallet wood dries completely.
Step #3: Sand The Whole Surface
Next is sanding the pallet surface to make a consistent and even absorption of your finish. Use 220 grit sandpaper and work with the direction of the wood grain pattern. If your wooden pallets have screw heads of protruding nails, remove them before sanding. You can check this guide if you need to remove screws with no head.
After removing your wooden pallet’s random roughness, wipe off the sand dust using a tack cloth. You can also use a rag to remove the dust particles on the surface completely.
Step #4: Treat The Pallet
Once you are done sanding the surface, you can apply your preferred finish. As mentioned earlier, you can have oil, varnish, stain, paint, or epoxy finish for your pallet.
From our experience, we applied multiple coats to treat wooden pallets. But we used wood conditioner before we treat pallets to ensure better absorption.
Also, we have to treat wood pallets in a well-ventilated area to avoid suffocation from the paint products.
Check for special instructions on the container of the finishing product you will use. Then you can customize the number of coats depending on your desired finished project.
Step #5: Wait Until The Finish Dries Up And Cure
You must wait two or three days to see the final results. The curing time varies on the number of coats you applied and also the products you used.
Remember that proper curing time is vital in treating wood to gain the desired results for your pallet wood.
