Complete Ipe Decking Installation Guide
Ipe (pronounced "EE-pay") is considered the gold standard of decking materials. Known as Brazilian Walnut, this extremely dense and durable hardwood offers unmatched longevity, natural beauty, and resistance to rot, decay, insects, and fire. With a Janka hardness of 3,680 lbf, Ipe is one of the hardest commercially available woods in the world.

Origin
Central & South America
Step 1: Acclimation & Storage
Stack Ipe boards on-site with 1x2 spacers between every layer for 7-14 days depending on climate. Keep boards off the ground with at least 6" clearance, covered with a breathable tarp but open on all sides for airflow. Never seal Ipe in plastic — it will develop mold. Ipe's extreme density means it responds slowly to moisture changes, making proper acclimation essential.
Step 2: Framing & Substructure
Ipe requires robust framing due to its weight (69 lbs/ft³). Maximum joist spacing is 16" on center, with 12" O.C. recommended for diagonal patterns or heavy-traffic commercial applications. Apply joist tape to ALL joist tops — this is mandatory, not optional. Ensure at least 18" of clearance underneath for ventilation and use stainless steel joist hangers throughout.
Step 3: Board Layout & Spacing
Mix light and dark boards throughout the deck for a balanced, natural appearance — do not segregate by color. Side gaps should be 3/16" and end gaps 1/4". Ipe is one of the most dimensionally stable decking materials available, meaning gaps remain relatively consistent year-round regardless of climate.
Step 4: Pre-Drilling & Fastening
Pre-drilling every single fastener hole is absolutely mandatory with Ipe — no exceptions. Use cobalt or titanium drill bits and stainless steel fasteners only (never galvanized or standard steel, which will cause black staining from tannin reactions). Options include face-screwing, hidden clip systems for grooved boards, or face-screwing with Ipe wood plugs for a concealed appearance.
Step 5: Cutting & End-Sealing
Use only 80-tooth carbide-tipped blades for clean cuts — standard blades will dull immediately. Seal ALL cut ends with wax-based end-grain sealer within minutes of cutting, applying at least 3 coats. This is the single most important step to prevent checking and splitting. Wear a dust mask, as Ipe dust is fine and can cause respiratory irritation.
Step 6: Finishing
Ipe can be finished with penetrating hardwood oil to maintain its rich brown color, treated with a UV-protective sealer to slow silvering, or left unfinished to weather naturally to an elegant silver-gray patina. If oiling, wait 3-4 weeks after installation before applying the first coat. Natural silvering is the lowest-maintenance option and is highly desirable on premium installations.
Step 7: Ongoing Maintenance
Sweep weekly and clean 2-3 times per year with mild soap and water. If oiled, re-apply annually. If left natural, essentially no maintenance is needed beyond cleaning. Ipe does not rot, resists insects naturally, and commonly lasts 50-75+ years. Never use salt, chemical de-icers, or metal shovels on an Ipe deck.
