Maintenance & Care

Cleaning

Clean the surface regularly with a mild detergent, avoiding harsh chemicals that can damage the wood.

Finishing

For enhanced longevity, a UV-resistant finish or sealant is recommended every couple of years to maintain color and prevent graying.

Weathering

Garapa naturally weathers to a silver-grey patina if left untreated, but regular maintenance can preserve its rich color.

Frequently Asked Questions

A 2x6 Garapa board weighs approximately 4.01 lbs per linear foot. Garapa 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 — Garapa 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 decking applications. While ground contact is possible, we recommend elevating Garapa boards at least 6" above grade for maximum lifespan.

Garapa outperforms composite in hardness (1,510 vs ~200 Janka), lifespan (up to 30+ years vs 25-30 years), and heat resistance. Unlike composites, Garapa won't melt, warp in extreme heat, or fade significantly. While initial cost is similar ($8-15/LF installed), Garapa costs less over its much longer lifetime. Composites do offer lower upfront maintenance.

Garapa 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.

Garapa is DIY-friendly with proper preparation. Key requirements: (1) Always pre-drill all screw holes — Garapa is too hard for direct screwing. (2) Use only 305 or 316 stainless steel fasteners — standard hardware will corrode and stain. (3) This pre-grooved profile uses hidden clip systems like Ipe Clip® for a screw-free surface. (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 2x6 Garapa board has actual finished dimensions of 1.5" × 5.5" (38.1 x 139.7 mm). The "2x6" 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 (1.5" × 5.5") when calculating material quantities and coverage for your project.

We responsibly, legally, and ethically source all our Garapa. We work only with suppliers who follow responsible forestry practices with full chain-of-custody transparency. Note: We are not FSC certified. Garapa trees grow naturally in diverse tropical forests and regenerate well under managed harvest. The extremely long lifespan (up to 30+ years) means fewer replacements compared to softwood or composite alternatives, reducing long-term environmental impact.
