Can Bona Traffic HD be used on Blackbutt?
Yes — Bona lists Blackbutt as a suitable substrate for Bona Traffic HD (covered under Bona's 'hardwood-generic' substrate listing).
Bona's TDS for Bona Traffic HD lists the following substrates: hardwood-generic, engineered, parquetry.
Blackbutt is covered by that list (covered under Bona's 'hardwood-generic' substrate listing). In practice, tannin-rich Australian hardwoods (Blackbutt, Spotted Gum) can require a neutralising primer before waterborne topcoats to prevent tannin bleed-through. Always confirm the primer/topcoat combination against the product's Specifier Paragraphs for the species at hand.
