The 5 Best Wood Treatment For A New Shed

Wood sheds are additional structures built in gardens and backyards to help in storing tools and other things.

Although wood is a very resilient material, it can be affected by general wear and tear. Before you can use these structures for storing, you need to add layers of protection. In fact, the best time to treat your woodshed is when it’s new. Here are the best options for treating a new woodshed. 

Treating wood is necessary to prolong the life of wooden structures, such as garden sheds. Most decorators recommend solvent-based wood preservers to treat garden sheds and other exterior wooden parts for efficiency and aesthetic effect on the wood. However, more and more people are changing to water-based wood preservers due to their eco-friendly materials. 

Do you need quick storage space for various tools or objects?

Or do you need a new office space for your remote work and activities? Perhaps, you and your friends want to have your mancaves or she-sheds. Whatever the reasons, your newly sanded wooden shed is finally here.

Before you can use and decorate your new structure, you need to get to work and treat the wood.

Why Treat The Wood Of Your New Garden Shed? 

Wood preservation has been present in carpentry since the time humans started building wooden structures. In fact, evidence of wood preservation has been seen way back when Alexander the Great has ruled Ancient Egypt. 

By soaking wood with olive oil, ancient carpenters were able to prolong its useful life. However, back in the day, only important wooden structures (like bridges and decks) are treated. Although tedious, treating wood gives a lot of benefits.

Adds New Layer Of Protection

Wooden structures are still vulnerable to natural damage, albeit with their sturdiness and reliability. It is still an organic material, which can accumulate mold, rot, decay, fungi growth, and more.

By treating the wood, you minimize the chances of these natural elements from happening. 

Prolongs The Life Of The Material

Since the shed will be exposed to different weather conditions, it would be vulnerable to damage. Moist and UV rays can weaken the material and can cause splits and cracks. When the wood is treated, the effects of the weather are also minimized or prevented. 

Keeps Your Stored Items Safe

Storing gardening tools and equipment in a space with untreated wood is a bad idea. Mainly because untreated wood tends to accumulate damages that grow over time.

If these damages made the wood fragile or damaged beyond repair, it would fail to keep your items safe inside the storage.

Contrary to popular belief, treating your wood as soon as you receive it from your wood supplier is recommended. This method helps preserve the wood at its best state possible.

However, treatment is not needed if the wooden components arrived pre-treated or is made with cedar or pressure-treated timber. 

What About Varnish? 

Varnish is a popular option for people who wants to add a layer of protection. Although it effectively makes the wood waterproof, it cannot be used alone to preserve the wood. That’s because it is a topcoat and does not go deep into the wood’s surface and fill up spaces. 

All the pores, dents, and uneven surfaces need to be filled to preserve the wood entirely. This step helps in avoiding moisture buildup, which causes cracks or organic growth. 

Like varnish, other topcoats lie paint, wax, or wood oil cannot fully protect the wood. Moisture can still form, which can lead to the gradual destruction of the wood. 

Should I Use Topcoat?

Topcoats are layers of materials used after the initial wood preserver was applied. These are usually used for decoration and waterproofing. If you want to add aesthetic elements and additional protection, you can add your preferred topcoats after the initial coating of the wood treatment. 

Using a preserver without a topcoat is fine. But using a topcoat without a preserver is not recommended. Take note: if you’re planning to add a topcoat, avoid using preservers that have wax. The wax makes the surface slippery, which causes any topcoat to slip away or be applied incorrectly. 

What Kind Of Wood Preservers Are There? 

As of now, there are two types of wood preservers in the market:


  • Solvent-Based – can be easily absorbed by the wood’s surface, generally great for any kind of wood, especially exteriors. 
  • Water-Based – also known as water-borne preservatives, these products dry quickly and doesn’t produce harmful odor or fumes. It is also not flammable, unlike most solvent-based preservatives.

How To Prep Up For Wood Treatment? 

You don’t need to do a lot of things to prep the wood for treatment.

This is especially true if the wood is newly sanded and fresh from the workshop. In most cases, simple cleanup is all that is needed before applying the wood preserver (follow the manufacturer’s instructions). But if you’re planning to treat a wood that is currently used, you need to prepare it for initial coating. 

Remove Any Particles (Dust, Dirt, etc.) From Wood

To make sure that the preserver can fill all the wood gaps, you need to clean any dust or dirt from the surface. The best way to do this is to wipe the wood with damp microfiber and then drying ut with a dry one.

Vacuum or air compressors are also good alternatives. 

Remove Any Organic Growth In The Wood

The next step is pretty straightforward: clean the wood’s surface with a fungicidal wash. Remove any algae, lichen, moss, or any organic things stuck in your wood.

Fungicidal wash can help in preventing any organic growth. Make sure that all the parts of these organic growths get removed to avoid further development. 

Strip Topcoats (Varnish, Paint, Stains, etc.) 

Wood preservers are considered undercoats and serve as a primer for other materials (like topcoats). All the undercoat layers need to be stripped away to renew wood treatment.

You can use sandpaper to remove the topcoats with minimal damages to the wood itself. 

Make Sure That The Surface Is Dry Before Applying Wood Preservers

Do not apply your wood preserver unless the wood is dry and no moisture is left. Moisture is the number one cause of wood breakage and cracks. Make sure that you dry it under the sun or use a dry cloth to remove the excess moisture.

How To Protect And Maintain Your Shed? 

1. Treat The Wood In The Shed Regularly

This doesn’t mean that you should apply wood treatment in the structure every month or so. Treat the wood at least once a year, especially when your area is prone to extreme weather. 


2. Lookout For Possible Insect Infestations

Insect infestation in wood is very destructive, but it can still happen even on treated wood. Take a good look at your shed inside and out and lookout for wood termites or other infestations.


3. Clean Both The Inside And Outside Structure

You can do this by removing dirt, molds, and organic growth. Avoid storing organic objects that can cause moist buildup. And make sure that your shed is always ventilated properly. 


4. Repair Holes As Soon As Possible

Due to wear and tear, the panels of your wooden garden shed can sustain damages and holes. When this happens, repair the holes immediately. Check for structural integrity if your shed received widespread damage. 


5. Clear Out Plants In The Nearby Area

Plants are generally harmless to the wood. However, insects that live on it are not. They can start a severe insect infestation if left unchecked. Additionally, bigger plants can affect the airflow and make your ventilation ineffective. Branches can also fall to the roof if a strong wind comes and sweep them away. To be safe, just clear out the area and avoid nearby plants from growing.
