Maintenance & Care

Cleaning

Regularly clean with mild detergent and water to prevent build-up of dirt and mildew. Avoid harsh chemicals that can strip protective oils.

Finishing

Apply a UV-protective finish periodically to maintain color and sheen, especially if the wood is directly exposed to sunlight.

Weathering

Tigerwood develops a natural patina over time; periodic oil application can enhance its appearance and longevity.

Frequently Asked Questions

A 1x4 Tigerwood board weighs approximately 1.28 lbs per linear foot. Tigerwood has a density of about 50-60 lbs/ft³, making it one of the densest commercially available hardwoods. Always factor weight into your structural and shipping calculations.

Yes — Tigerwood is rated Durability Class 1 (Very Durable) and is naturally resistant to rot, decay, insects, and fungal attack without chemical treatment. It is naturally durable and performs exceptionally well in full exterior exposure including soffit applications. While ground contact is possible, we recommend elevating Tigerwood boards at least 6" above grade for maximum lifespan.

Tigerwood outperforms composite in hardness (2,170 vs ~200 Janka), lifespan (up to 40+ years vs 25-30 years), and heat resistance. Unlike composites, Tigerwood won't melt, warp in extreme heat, or fade significantly. While initial cost is similar ($8-15/LF installed), Tigerwood costs less over its much longer lifetime. Composites do offer lower upfront maintenance.

Tigerwood requires minimal maintenance. Without treatment, it naturally weathers to an elegant silver-gray patina over 6-12 months. To maintain the original warm brown color, apply a UV-inhibiting penetrating oil (like Ipe Oil or Penofin) once or twice annually. Cleaning involves periodic washing with a mild soap solution. No sanding, staining, or sealing is required for structural durability.

Tigerwood is DIY-friendly with proper preparation. Key requirements: (1) Always pre-drill all screw holes — Tigerwood is too hard for direct screwing. (2) Use only 305 or 316 stainless steel fasteners — standard hardware will corrode and stain. (3) Face-screw with stainless steel trim-head screws. (4) Allow boards to acclimate on-site for 5-7 days before installation. A compound miter saw with a carbide-tipped blade is recommended.

A nominal 1x4 Tigerwood board has actual finished dimensions of 0.75" × 3.5" (19.0 x 88.9 mm). The "1x4" is the nominal (rough-cut) size — after kiln drying and precision surfacing, all hardwood lumber finishes slightly smaller. This is standard across the lumber industry, similar to how a nominal 2×4 softwood measures 1.5" × 3.5". Always use the actual dimensions (0.75" × 3.5") when calculating material quantities and coverage for your project.

We responsibly, legally, and ethically source all our Tigerwood. We work only with suppliers who follow responsible forestry practices with full chain-of-custody transparency. Note: We are not FSC certified. Tigerwood trees grow naturally in diverse tropical forests and regenerate well under managed harvest. The extremely long lifespan (up to 40+ years) means fewer replacements compared to softwood or composite alternatives, reducing long-term environmental impact.
