Bona does not explicitly address the combination of Bona Classic on Grey Box. Grey Box is classified medium-high tannin.
Bona Classic TDS names only Blackbutt and Tallowwood; Grey Box is not called out.
The conservative default is to follow Bona's general primer-selection logic:
• For high-tannin or dark hardwoods: specify Bona Intense.
• For softwoods and parquetry: Bona Classic is particularly suitable.
• For a whitewashed look on pale hardwoods: Bona White is the intended primer.
• Under Bona Traffic HD Raw: use Bona Classic UX.
A trial application is essential whenever the matrix status is 'unlisted'.
