Bona's primer range splits into two jobs — bonding primers that prepare wood for a topcoat, and colour-effect primers and treatments that shift the tone of the wood before sealing.
Bonding Primers: Classic and Classic UX
Bona Classic (1L) and Classic UX (5L) are single-component acrylate primers used ahead of Bona waterborne finishes, giving the surface a well-bodied appearance and reducing the risk of side-bonding thanks to their flexibility and high solids content. Classic UX is specifically suited to light wood colouration, with low viscosity and forgiving application across all wood types.
Colour-Effect Primers: White, Amber and Natural
Bona White Primer creates a whitewashed effect suited to Scandinavian-style interiors, with the level of whiteness controlled by how many coats are applied, while also preventing yellowing over time. Bona Amber Primer goes the other way, adding an intense, rich, warm colouration with a fast drying time and low VOC content. Bona Natural Primer does neither — it's designed to retain the wood's genuinely unfinished appearance, typically paired with Bona Mega Natural or Bona Traffic Natural lacquers to keep that raw look while still achieving a durable, sealed surface.
Toning Treatments: Nordic Tone and Rich Tone
Bona Nordic Tone is a Scandinavian-style toning treatment, typically combined with Bona Craft Oil afterwards for the final colour and protection. Bona Rich Tone works differently — a pre-treatment specifically for oak floors, creating a rich, dark brown colouration that gives the impression of smoked oak, later sealed with Bona Craft Oil or Hardwax Oil depending on the desired finish. Rich Tone can also be adjusted with up to 5% Bona stain to fine-tune the final colour.
Bona Gel: Trowel-Applied Levelling Primer
Bona Gel is a high-viscosity primer applied with a trowel, usable on untreated wood or between coats of finish. It dries rapidly with minimal grain raise, and between coats it can reduce visible abrasion scratches and fill small surface irregularities for a flatter, more even base before the topcoat goes on.
Common Questions About Bona Primers and Treatments
What's the difference between Bona White Primer and Bona Natural Primer?
White Primer builds a whitewashed effect, with whiteness controlled by the number of coats applied. Natural Primer does the opposite — it preserves the wood's genuinely unfinished, untreated look under a durable topcoat.
Do I need a bonding primer before every Bona lacquer?
It depends on the specific finish and floor condition — bonding primers like Classic or Classic UX are commonly used to reduce side-bonding risk, but check the specific lacquer's application guidance.
How is Bona Rich Tone different from a standard stain?
Rich Tone is a pre-treatment specifically for oak, creating a dark, smoked-oak effect that's then sealed with Bona Craft Oil or Hardwax Oil, rather than a standalone colour product used across all wood types.
When would I use Bona Gel instead of a standard primer?
Bona Gel is trowel-applied and higher viscosity, making it useful for filling small surface irregularities or reducing visible scratches between coats, not just as an initial primer on bare wood.
