Complete Guide to Reclaimed Ulin Ironwood Decking
Reclaimed Ulin ironwood decking is designed for demanding outdoor spaces including pool decks, terraces, garden decks, resort walkways and tropical hospitality projects. At Kaltimber, each decking board is manufactured from reclaimed Ulin selected for durability, density and long-term performance in humid tropical climates.
What Is Reclaimed Ulin Decking?
Reclaimed Ulin decking is outdoor decking manufactured from Ulin ironwood recovered from existing Indonesian structures and processed for reuse. Its natural density, durability and resistance to termites and decay make it particularly suitable for pool decks, terraces, resort walkways and other outdoor applications in tropical climates.
Applications for Reclaimed Ulin Decking
Reclaimed Ulin decking can be used across a wide range of residential, hospitality and architectural projects, particularly in tropical environments.
Pool decks — durable hardwood decking for humid outdoor areas around swimming pools.
Terraces and outdoor living areas — for villas, residences, restaurants and hospitality spaces.
Resorts and hotels — including walkways, guest areas and outdoor communal spaces.
Balconies — where a durable natural timber finish is required.
Garden decks — for landscaped outdoor areas and private residences.
Architectural outdoor spaces — custom decking applications designed by architects and contractors
How Does Reclaimed Ulin Perform Outdoors?
Reclaimed Ulin is naturally dense and durable, with strong resistance to termites, decay and demanding tropical conditions. As with any natural timber, correct installation, drainage and detailing remain important for long-term performance.
Reclaimed Ulin Sourcing & Traceability
Kaltimber manufactures decking from reclaimed Ulin recovered from existing Indonesian structures rather than newly harvested timber. Each board is inspected and recorded through our production process, and Kaltimber operates under Indonesia’s SVLK timber legality system.

Construction & Installation
Who Installs Kaltimber Decking?
Kaltimber manufactures and supplies reclaimed Ulin decking but does not provide installation directly. Installation is normally carried out by the client’s contractor or specialist decking installer. For projects in Bali, we can recommend experienced installers on request.
Installation Considerations for Reclaimed Ulin
Reclaimed Ulin is a very dense hardwood, so correct installation methods, suitable tools, outdoor-grade fasteners, adequate drainage and appropriate joist spacing are important for long-term performance. Follow Kaltimber’s decking installation recommendations or work with an experienced hardwood decking installer.
Budget & Costs
How Is Reclaimed Ulin Decking Priced?
Reclaimed Ulin decking is priced according to the specifications of each project. The main factors include board profile, width, length selection, surface finish, quantity and any specific machining requirements.
Because projects vary significantly in size and specification, Kaltimber provides project-specific quotations rather than using a single fixed price per square metre.
What Factors Affect the Cost?
The main factors influencing the price of reclaimed Ulin decking are:
Board dimensions and profile
Width and thickness
Random, incremental or fixed lengths
Rustic or smooth finish
Quantity required
Special machining or custom specifications
Delivery destination
Kaltimber has no minimum order quantity for reclaimed Ulin decking and can supply anything from a small residential project to large hospitality and architectural developments.
Requesting a Quotation
For an accurate quotation, provide your required dimensions, approximate area, preferred profile, finish and project location. Our team can then recommend an appropriate specification and prepare a quotation based on your requirements.
Maintenance & Care
How Much Maintenance Does Reclaimed Ulin Decking Require?
Reclaimed Ulin is naturally dense and durable and requires relatively little maintenance compared with many softer outdoor timbers.
Maintenance requirements depend largely on the desired appearance of the deck. Ulin can be allowed to weather naturally, or it can be periodically cleaned and treated with a suitable exterior decking oil to help maintain a darker timber colour.
How Should Reclaimed Ulin Decking Be Cleaned?
For routine cleaning, remove leaves, dirt and organic debris and wash the surface using water and a mild cleaning solution when necessary.
Good drainage and ventilation are particularly important in tropical environments. Keeping the surface free from accumulated organic matter helps maintain the appearance and condition of the decking.
Does Ulin Decking Need to Be Oiled?
Oiling is primarily an aesthetic choice rather than a requirement to make Ulin durable.
Without oil, exposed Ulin will gradually weather and develop a natural aged appearance. Clients wishing to retain a darker or richer timber tone can apply a suitable exterior decking oil periodically according to the product manufacturer’s recommendations.
How Does Ulin Age Outdoors?
Like other natural hardwoods, Ulin changes colour when exposed to sunlight, rain and weather.
The speed and appearance of this weathering depend on exposure, location and maintenance. Regularly oiled decking generally retains a deeper timber colour, while untreated decking gradually develops a more naturally weathered appearance.
Choosing Reclaimed Ulin Decking
What Should Be Considered When Specifying Decking?
The right decking specification depends on the architecture, expected traffic, installation method, surrounding environment and desired appearance.
Important considerations include:
Board width and thickness
Length selection
Surface finish
Joist spacing
Drainage and ventilation
Fastening system
Poolside or high-moisture exposure
Desired long-term appearance
Maintenance expectations
For demanding tropical projects, material durability should be considered alongside design and installation quality.
Narrow or Wide Decking Boards?
Both narrow and wide boards can be used depending on the design of the project.
Narrow boards can create a more detailed linear appearance and may suit curved areas or particular architectural layouts. Wider boards provide a broader visual surface and can create a more substantial appearance.
The appropriate choice depends on the dimensions of the project, architectural design and installation requirements.
Rustic or Smooth Finish?
Kaltimber offers reclaimed Ulin decking in two principal finishes.
Original Rustic retains more of the texture and character associated with reclaimed timber.
Classic Smooth provides a cleaner and more refined surface while maintaining the natural variation and character of reclaimed Ulin.
The choice is primarily aesthetic and depends on the architectural style of the project.
Why Reclaimed Ulin?
Reclaimed Ulin combines the natural durability of one of Indonesia’s most respected tropical hardwoods with the environmental advantage of reusing timber that has already served in existing structures.
Rather than relying on newly harvested Ulin, Kaltimber recovers suitable timber from dismantled Indonesian structures and processes it for a new architectural use.
Its density, natural durability and resistance to termites and biological decay make reclaimed Ulin particularly suitable for demanding outdoor applications such as pool decks, terraces, villas, resorts and hospitality projects.
Each reclaimed board also carries variations in grain, colour and character that distinguish reclaimed timber from newly manufactured uniform materials.
