Solid merbau wood varies from brown to red (the sapwood is light yellow; when freshly cut, the solid wood is pale yellow to orange-brown in colour and then darkens to copper brown. The colour of the sapwood contrasts sharply with that of the solid wood.
Despite being very hard, merbau has good workability, especially when hard metal tools are used. Holes must be pre-drilled for nails and screws. It glues well. Stains and marks may appear when washed with water-soluble substances. Treatability – not permeable (sapwood quite permeable; EN 350-2, 1994). Contact with iron ions can stain the wood (iron reactions – tannin). For indoor and outdoor use. It is especially suitable for building frames (windows, doors, conservatories), floors (parquet, planks, etc.), stairs, cladding for walls and ceilings (interiors), furniture.
