Bona Traffic HD is one of Bona’s premium two-component waterborne wood floor lacquers, developed for demanding domestic and commercial environments where durability and rapid return to use are important.
This updated FAQ covers the current Bona Traffic HD range stocked by Wiltshire Wood Flooring Supplies, including coverage, drying, sheen levels, mixing, application, recoating and maintenance.
Bona Traffic HD FAQs
1. What is Bona Traffic HD?
Bona Traffic HD is a premium two-component waterborne polyurethane lacquer designed for wooden floors exposed to high traffic and demanding use.
It combines rapid hardness development with high wear and chemical resistance, making it suitable for busy domestic homes, shops, hospitality, offices and other commercial environments.
2. How quickly does Bona Traffic HD dry?
Under normal conditions, Bona Traffic HD can normally be sanded or recoated after approximately 2–3 hours.
Careful foot traffic is generally possible after around 8 hours after the final coat, and Bona states that the floor can return to full use after approximately 12 hours.
Lower temperatures, high humidity, poor ventilation or heavy application will extend drying times.
3. What is the coverage of Bona Traffic HD?
The recommended application rate is approximately 8–10m² per litre, per coat.
One 4.95L mixed pack therefore covers roughly 40–50m² for one coat, depending on the surface and application rate.
4. How many coats of Traffic HD should I apply?
On freshly sanded bare timber, Traffic HD is normally used as part of a complete Bona system with a compatible primer followed by two lacquer coats.
The exact treatment schedule depends on the primer and desired appearance. Avoid simply adding extra coats without need; Bona recommends using the coating system specified for the project.
5. Does Bona Traffic HD need a primer?
On freshly sanded bare timber, a compatible Bona wood floor primer is normally applied before Traffic HD.
The primer affects colour, side-bonding behaviour and the overall coating system.
WWFS stocks Bona Classic UX, Natural, White, Intense and Amber primers for different visual effects.
6. Which sheen levels are available?
The current Traffic HD range stocked by WWFS includes:
- Silkmatt
- Matt
- Extra Matt
- Anti-Slip
For an even lower-sheen, untreated timber appearance, choose Bona Traffic HD Raw, which is a separate product within the Traffic HD family.
7. What is the difference between Traffic HD and Traffic HD Raw?
Standard Traffic HD provides premium durability with a conventional lacquered surface available in several sheen levels.
Traffic HD Raw is specifically designed to retain the look and tactile feel of untreated timber, with an ultra-matt surface and minimal visible reflection.
For the closest freshly sanded appearance, WWFS normally recommends Bona Natural Primer followed by two coats of Traffic HD Raw.
8. How do I mix Bona Traffic HD?
The current 4.95L pack contains approximately 4.54L of lacquer plus 0.41L of hardener.
Add the supplied Traffic HD hardener to the lacquer and mix thoroughly according to the current Bona instructions.
If mixing a smaller quantity, maintain the exact manufacturer mixing ratio rather than estimating by eye.
9. Can Bona Traffic HD be used over an existing lacquer?
Yes, where the existing coating is sound and compatible, but proper preparation is essential.
Bona’s current professional recoat system involves thorough deep cleaning followed by controlled superficial abrasion before applying a fresh coat of Traffic HD.
For used lacquered timber floors, Bona currently specifies abrasion with suitable Bona Diamond Abrasives as part of its professional recoat treatment.
10. Can Traffic HD be used on factory-finished flooring?
Potentially, yes. Bona includes Traffic HD within its professional recoating systems for compatible prefinished wood floors.
Factory coatings vary considerably, so the floor must be thoroughly cleaned, correctly abraded and assessed for adhesion before the whole area is treated.
11. Can Bona Traffic HD be used on engineered wood flooring?
Yes. Traffic HD is suitable for solid and engineered timber flooring where the surface is genuine wood and suitable for the intended finishing or recoating process.
For a full renovation of engineered flooring, confirm that sufficient wear layer remains before sanding.
12. Can Traffic HD be used on parquet and herringbone?
Yes. Traffic HD is commonly used on professionally sanded parquet, herringbone and other timber floor formats.
The floor must be evenly sanded and properly prepared before the primer and lacquer system is applied.
13. Is Traffic HD suitable for busy homes with children and pets?
Yes. Traffic HD is designed for demanding traffic and has very low indoor emissions.
Bona Traffic HD is GREENGUARD Gold certified and is used in environments including schools and nurseries.
No wooden floor finish is completely scratch-proof, however, so entrance matting, furniture protection and regular removal of abrasive grit remain important.
14. Is Bona Traffic HD non-yellowing?
Yes. Traffic HD has a clear, non-yellowing formulation.
However, the colour of the finished floor is also influenced by the timber and the primer underneath, and natural wood itself can change colour gradually through ageing and UV exposure.
15. Can Bona Traffic HD be used outdoors?
No. Traffic HD is designed for interior wooden floors and should not be used as an exterior timber coating.
16. How should the floor be prepared before Traffic HD?
On bare timber, the floor should be professionally sanded to a uniform finish, thoroughly vacuumed and free from dust, oil, wax, silicone and other contamination.
Existing lacquered flooring requires a different preparation route: deep cleaning, compatibility assessment and uniform abrasion before recoating.
17. Do I need to sand between coats?
Not automatically.
When subsequent coats are applied within the approved recoat window, intercoat sanding may not be required for adhesion. Abrasion can still be useful where the previous coat contains raised grain, dust particles or other surface imperfections.
If the recoat window has been exceeded, follow Bona’s current abrasion guidance before applying the next coat.
18. What roller should I use?
Use the roller recommended for the exact Traffic HD product and application system.
WWFS stocks professional Bona rollers and applicators designed for Bona waterborne floor coatings.
19. How do I clean a floor finished with Traffic HD?
Regularly remove grit using a vacuum or dusting pad, then damp-clean when required using a compatible lacquered wood-floor cleaner.
The Bona Premium Wood Floor Spray Mop and Bona Wood Floor Spray Cleaner are suitable everyday maintenance options.
Avoid steam cleaners, standing water and harsh household detergents.
20. What should I do if the floor becomes scratched?
The correct treatment depends on the depth of the damage.
Fine surface wear may be addressed through appropriate maintenance. Where the lacquer remains intact but is visibly scratched or worn, Bona’s professional recoat treatment may restore the floor without complete sanding.
Deep damage that penetrates into the timber may require local repair or full sanding and refinishing.
21. Can Traffic HD be recoated in the future?
Yes. Recoating is actually one of Traffic HD’s strengths.
Bona’s current professional system uses deep cleaning and superficial sanding with Bona Diamond Abrasives, followed by one or more fresh layers of Traffic HD where appropriate.
Periodic recoating can renew the protective layer before wear reaches bare timber.
22. Does an existing floor always need to be sanded back to bare wood?
No. If the existing lacquer remains well bonded and compatible, a professional clean, abrasion and recoat may be sufficient.
Full sanding is more appropriate where the coating has failed, deep staining is present, extensive timber damage exists or the colour needs to be changed completely.
23. Is Traffic HD suitable for kitchens?
Yes. Traffic HD’s durability and chemical resistance make it a strong choice for suitable wooden kitchen floors.
Spills should still be removed promptly and standing water should never be left on a timber floor.
24. How is Traffic HD different from Bona Mega EVO?
Bona Mega EVO is a ready-to-use one-component lacquer and is an excellent choice for most domestic flooring projects.
Traffic HD is a two-component premium system designed for more demanding use, faster hardness development and very high wear resistance.
For busy homes, commercial interiors and situations where downtime must be minimised, Traffic HD is normally the higher-specification option.
