The finished appearance
Ipe offers natural grain and color variation. It can be maintained toward its brown tone or allowed to weather; the result depends on exposure and care. Composite offers a selected manufactured color and texture. Compare several boards rather than a single small sample. Neither natural grain nor embossing proves slip performance.
Ownership and repair
Ipe cleaning and inspection remain necessary even when no color-preserving oil is used. Applying oil adds an appearance-maintenance task. Composite generally avoids routine wood staining, but still needs approved cleaning and spill management. Ask how each product handles a localized scratch, a stained board and a future board replacement. New boards may differ from weathered boards in either system.
Installation reality
Ipe requires suitable tools, fastening and attention to moisture movement and ventilation. Composite requires the approved support spacing, fasteners and temperature-aware gaps. Check diagonal spans and stairs independently. Neither surface fixes weak framing, poor flashing or a blocked drainage path.
Choose by priorities
Favor Ipe when real wood, natural variation and the option to weather are important. Favor composite when a controlled color palette and reduced refinishing are more important. Compare complete delivered and installed quotations; do not assume one is automatically the expensive option.
