Douglas Fir is celebrated for its strength and unique character, the charing process forms a stable, protective carbonized layer that resist rot, insects and moisture. It’s beauty enhances over time through the slow weathering process. This means you get a product that is not only incredibly strong and weatherproof but also virtually maintenance-free.
This product can be customized to your specifications. Please enquire through our custom-orders form.
SPECIFICATIONS:
Ensure you purchase your pieces with enough length to be concreted into the ground, while leaving sufficient above ground clearance. We’ll also provide installation instructions and some tips and tricks to make this easier
Strong, wear-resistant, weatherproof, low-maintenance and durable.
KEY POINTS OF INTEREST:
Guarantee doesn’t cover variation in color or texture due to natural weathering.
HOW IT WEATHERS:
Charred wood doesn’t “fail” like painted timber. It slowly evolves, how this happens depends on your maintenance philosophy.
First 6–12 months
Loose carbon particles may shed slightly (especially where there's deep char).
Color shifts from jet black to a softer charcoal.
UV light starts breaking down any oil finish.
1–3 years
If sealed with natural oil: tone warms a bit (black → dark brown-black).
Texture becomes more pronounced as softer grain ercedes slightly.
In wet climates, wood develop a subtle silvery cast on high spots.
5+ years
Properly charred and installed boards remain structurally solid.
The look becomes matte, mineral-like — less glossy, more architectural.
Minimal cracking beyond what formed during charring.
This slow aging is actually the point — similar to how traditional siding in Japan was valued for stable, dignified weathering rather than looking “new.”
MAINTENANCE (CHOOSE YOUR PHILOSOPHY)
Option 1: Let it age naturally (lowest maintenance)
What happens:
Color softens and becomes more organic.
No recoating required unless you want to refresh appearance.
Care:
Rinse dirt off annually with low-pressure water.
Brush gently if debris collects in grain.
Option 2: Maintenance plan for a rich black finish
A standalone garden feature is the perfect place to keep that deep, sculptural black. To maintain the dark char on Douglas fir outdoors, think of it as protecting the sealant, not the char itself.
1) Use the right finish from day one:
For a garden installation exposed on all sides:
Best choices:
Exterior penetrating oil with UV inhibitors
Tung-oil–based exterior blends
These soak in and “feed” the char without forming a peelable film — closer to traditional practice from Japan.
Avoid:
Thick varnish or polyurethane outdoors (they crack and look patchy on char).
2) Re-oiling schedule (with realistic timing)
Because your piece is fully exposed:
First refresh: 12 months after installation
Then: every 2–3 years (annually if in strong sun or coastal weather)
If you want it consistently black, lean toward the shorter interval.
Application routine:
Clean surface gently (soft brush + water, let dry fully).
Apply thin oil coat with brush or cloth.
Wait 15–30 min then wipe off excess.
Let cure dry.
Thin coats keep the surface crisp and matte instead of shiny.
3) Visual cues it needs attention:
Don’t rely only on time alone, watch the wood:
Color drifting toward gray or brown
Surface looks dry or dusty
Rainwater stops beading on the surface
Touch feels slightly chalky
Those signs mean UV has eaten the protective oil layer.
Quick yearly care routine
Once a year (takes ~15 minutes):
Rinse or gently brush off dirt
Inspect for dryness
Spot oil sun-facing areas if needed
That’s it — no sanding, no stripping, no repainting cycles.
