Maintaining Your Thermory Project
How do you keep your Thermory project looking and performing its best for decades? Well, that depends on the look you want. Like all real wood, Thermory boards will age and grey over time unless you apply something to delay the process. So the first step is to decide if you’d like to maintain the original brown color, or allow your boards to age naturally.
Natural Brown
The natural result of our modification process is a rich brown color. Maintaining this color on an exterior application requires more time and effort.
Silver
Over time, wood will age to a stunning silver. Allowing your wood to age naturally requires very little maintenance.
While the brown color is the natural result of our thermal modification process, the silver is a result of wood’s natural aging process through exposure to the elements. UV light and rain both accelerate the aging process – the amount of exposure influences how quickly your project will age. With direct exposure to sunlight, your project may age to silver in as little as 6 months. To maintain the original color outdoors, boards must be treated with a penetrating UV protective oil.
Whether you choose to keep the brown or let it silver, your Thermory wood will maintain its core qualities.

SMOOTH KISSED
Milling so smooth you’ll have to touch it to believe itHow To Maintain Your Thermory Product
For exterior projects, your maintenance requirements and routine differ based on your desired outcome and the Thermory product you choose. Our finished product line Ignite, has different maintenance needs than our natural Benchmark or Kodiak product lines. Though the maintenance may vary, the performance of our boards does not. That means there are no wrong choices – just decades of rot resistance and stability with the look of your choice.
Maintaining Natural Brown (All Species)
- Prefinish prior to installing.* This step is critical to slow the aging process on all sides of the wood. Prefinishing should be done with a penetrating UV protectant oil.
*Â Thermory strongly recommends factory finishing to protect all sides of the wood. Results may vary if protection is applied after installation.
- Depending on exposure to direct sunlight, to exposed surfaces after 1 year or per manufacturer’s directions. For projects with more direct sun exposure, reapplication may be required sooner.
- Follow the instructions provided by oil manufacturer for application.
- Sand the surface of the deck before 1st application
(Almost) No Maintenance Required
Allowing your Thermory wood to naturally age to a stunning silver is your easiest option when it comes to maintenance – and it won’t impact the longevity or stability of your project at all!
- Prefinish prior to installing. This step, though not required, is critical to allowing the wood to age evenly and prevent checking. Prefinishing should be done with a penetrating oil with UV protectant.
- Keep your deck clean. Yeah – that’s really it. Enjoy your 25+ years!
Maintain With Periodic Repainting
The bold look of Ignite does require some repainting to stay fresh outdoors. The paint has been tested to last 5 years. For Dragon Scale products, the texture is embossed into the surface of the board, therefore the texture will not require refinishing.
- Repaint as needed. Color matches are available through Sherwin-Williams.
- We recommend avoiding spot-painting, and instead repainting the whole wall or section at once.
- For Dragon Scale projects, we recommend reapplying the paint with an airbrush system.
Wish It Was Still Brown? No Problem!
If you allowed your wood to age to silver and miss the original color, getting it back may be easier than you think!
- Clean the surface with a wood brightening cleaner.
- A stiff-bristled brush is your best choice.
- If you prefer power washing, use the lowest setting and the widest fan.
- Wait 1 day before oil application.
- Apply a UV protectant oil according to manufacturer’s directions
- That’s it! Re-oil annually or as needed to maintain color, as described above.
For Long-Term Performance, We Recommend Factory Finishing
Whether you choose to maintain the original brown or allow your wood to age to silver, Thermory always recommends factory finishing prior to installation. We’ve partnered with our distributors to ensure every order can be factory finished before being shipped to our customers. There are a couple reasons we always recommend this critical step.
Protection On All Sides
Flood-system finishing allows for all 6 sides of every board to be thoroughly coated in your finish. While the surface sides may require ongoing maintenance, an initial coating of oil is enough to protect ground- or inside-facing surfaces from trapped moisture for the lifetime of your project.
Consistent Color
An initial coating of oil allows the wood to age evenly – whether you’re planning to maintain the original color or allow it to silver. We recommend a penetrating oil in part for this very reason – by conditioning the wood beyond the surface, it will all age at the same pace.
Smooth-Surface Maintenance
Factory finishing with a penetrating oil also helps reduce checking and shaking over time. By conditioning the wood with a penetrating oil, small imperfections that often occur over time are prevented. We’re proud of our Smooth Kissed Milling texture – factory finishing allows it to last even longer.
We recommend factory finishing so strongly that we’ve partnered with our distributors to make sure factory finishing is always available on any Thermory order. Whether you order direct from Thermory or through one of our regional distributors, be sure to ask about factory finishing!
