Blackbutt is named in the Bona Classic TDS as not recommended; high-tannin contraindication applies.

Use Bona Intense instead. Bona's own Classic and Classic UX datasheets both explicitly direct specifiers to substitute Bona Intense as the primer when the species is in the high-tannin category. Using Classic or Classic UX over Blackbutt, Tallowwood or similar high-tannin hardwoods risks tannin bleed-through, uneven colouration and delayed drying.
