How to Seal Pallet Wood for Outdoor Use: Step-By-Step
Things you need
- Palm sander/sandpaper
- Soft tack cloth
- Wood conditioner
- Good quality sealer/ Wood stain
- Paint brushes/Spray bottle
- Hand gloves
- Safety glasses
- Face mask
1. Prepare and clean the pallets
Disassemble and dry clean the pallet wood that you want to seal for outdoor use. The cleaner the pallets, the better the application will be. Other than that, cleaning beforehand helps make them last longer. Get rid of any mold or fungus visible on the surfaces.
2. Sand down the surfaces
Mask up, wear your glasses, and use a palm sander for best results. You can use sandpapers to manually sand down the pallet wood surface going with the grain. This will allow for a cleaner and slicker finish.
3. Make sure to clean the dust with the tack cloth as you sand
The dust will stick on the sealer and prevent it from setting correctly if you just sand the pallets and don’t remove the dust thoroughly.
4. Dry up the pallet wood completely
You should only apply the sealer when the wood contains absolutely no moisture or haze in or around it. Do not apply sealant on a humid day.
5. Apply wood conditioner to boost the pallet’s ability to absorb the sealant
Get a container of pre-stain wood conditioner and brush up the wood surfaces with it once they’re clean and rubbed down. It removes the thin mildew coating and makes a huge difference in the finish.
6. Light coat the pallet with the sealer, let it dry, and repeat
Take your time and coat the pallet wood several times. Take some sealer in a smaller container, dip the paint brush into the sealer a little, and keep on brushing the pallets. Let them absorb the treatment and brush them when they seem dried up again. The thicker coating may cause an inconsistent finish.
7. Topcoat with polyurethane to finish up the task
Polyurethane gives the pallets a fine shine and extra durability against rainwater and sunlight. It also protects wood from scratches and prevents liquids such as oil, grease, and water from penetrating into the wood.
Different types of pallet sealants and stains for outdoor use
The water-oil emulsion formula goes four layers deep in the pallet wood and offers excellent water resistance. Non-toxic and easy-to-clean, there are 24 different color variants to choose from.
These are the water-based fast-drying types of sealants that go down to only one layer of the pallet cells. They work best for wood trims, frames, spindles, railings, and sidings.
Deep penetrating sealants
These oil-based sealants penetrate about half an inch deep into the wood and do not form a surface film like most other sealant types, which prevents wood from flaking. On the downside, they leave a greasy residue behind at times.
Shallow penetrating sealants
Shallow penetrating sealants are oil-water emulsions. They penetrate four layers of the pallets and protect them from any liquid spills just like the pure color sealants. These stains work to ensure your pallets’ longevity.
