Light use is possible after approximately 6 hours , with the floor returning to full traffic after approximately 12 hours under normal drying conditions.

Each pack contains 4.54L of polyurethane lacquer plus 0.41L of hardener , giving approximately 4.95L of mixed product . Available in Silk Matt, Matt, Extra Matt and Anti-Slip finishes.

Using Bona Traffic HD Over Bona Craft Oil 2K

Bona Craft Oil 2K can be used beneath Bona Traffic HD to create a coloured timber floor with the excellent wear resistance, chemical resistance and easy maintenance of a professional polyurethane lacquer system.

This combines the colour and grain enhancement of a penetrating oil with the protective surface performance of Bona Traffic HD. It is particularly useful in busy homes and commercial interiors where an oil-only finish may require more frequent maintenance.

Craft Oil 2K Preparation Before Lacquering

  1. Apply one thin, controlled coat of Bona Craft Oil 2K to correctly sanded bare timber.
  2. Work the oil thoroughly into the timber using the selected application method.
  3. Remove every trace of surplus oil using clean Bona Oil Cloths .
  4. Do not leave wet oil, heavy deposits, roller texture or visible residue on the timber.
  5. Allow coloured Bona Craft Oil 2K to dry for at least 12 hours under normal conditions.
  6. Allow additional drying time where conditions are cool, humid or poorly ventilated, or where the timber species slows oil curing.
  7. Rub the dried surface firmly with a clean white cotton or paper cloth.
  8. If noticeable pigment transfers onto the cloth, the Craft Oil is not ready to be lacquered and must be allowed to dry for longer.
  9. Once the surface is fully dry, buff the complete floor evenly using a red floor pad.
  10. Vacuum the floor thoroughly to remove all loosened pigment, dust and residue.
  11. Apply two even coats of Bona Traffic HD at the recommended application rate.

Important Craft Oil System Requirements

  • Bona Craft Oil 2K must be used on its own without Bona Rich Tone or other additives when it will be overcoated with Bona Traffic HD.
  • All surplus oil must be removed before the drying stage.
  • The floor must be completely dry before red-pad buffing and lacquering.
  • Do not proceed while noticeable pigment transfers onto a clean white cloth.
  • Always carry out a representative test using the complete Craft Oil and Traffic HD system.
  • The timber species, sanding sequence, selected oil colour and lacquer sheen will all influence the final appearance.

Recommended Application Tools

Floor Preparation

  • Allow the floor to acclimatise to its normal end-use environment.
  • Sand untreated flooring evenly back to clean, bare timber.
  • Complete the final sanding sequence consistently across the full area.
  • Remove all sanding dust using professional extraction and vacuuming.
  • Ensure the surface is dry and free from wax, polish and contamination.
  • Where using Bona Craft Oil 2K as the colour base, follow the complete Craft Oil drying, pigment-transfer testing, red-pad buffing and vacuuming procedure before applying Traffic HD.
  • Allow the lacquer and hardener to reach room temperature before mixing.
  • Ideal application conditions are approximately 18-25°C and 30-60% relative humidity.
  • The minimum application temperature is 13°C.

Mixing

  1. Shake the lacquer container before adding the supplied hardener.
  2. Add the complete 0.41L hardener to the 4.54L lacquer when mixing the full pack.
  3. Immediately shake the combined mixture vigorously for approximately 60 seconds.
  4. Use standard Bona Traffic HD within approximately four hours, or the Anti-Slip version within approximately three hours.
  5. When mixing smaller quantities, use the Bona Mixing Bottle and follow the measurement divisions on the hardener container.

Application

  1. Apply evenly using a Bona floor finish roller at approximately 8-10m² per litre.
  2. Roll alternately across and with the direction of the timber grain.
  3. Maintain a wet edge and avoid puddles, heavy deposits and dry overlaps.
  4. Allow approximately 2-3 hours drying before applying the next coat.
  5. Where required, carry out intermediate abrasion using the Bona Scrad System at P150 grit or finer and remove all dust.
  6. If the previous lacquer coat has dried for longer than 24 hours, intermediate abrasion is mandatory before recoating.
  7. Do not apply more than two full coats of waterborne primer or lacquer in one day, as excessive moisture may cause timber swelling.
  8. Maintain good ventilation throughout application and drying.

Gap & Surface Preparation

Before applying the selected primer, Bona Craft Oil 2K or Bona Traffic HD, fill suitable fine joints and minor defects using Bona Mix & Fill Plus . Allow the filler to dry fully, complete the final sanding process and remove all dust before coating.

Cleaning & Maintenance

  • For routine cleaning, use the Bona Premium Wood Floor Spray Mop or another pH-neutral cleaner designed for lacquered wood flooring.
  • For economical refilling, use Bona Wood Floor Cleaner 4L .
  • Floors finished using Bona Craft Oil 2K beneath Bona Traffic HD should be maintained as lacquered floors rather than oil-only floors.
  • Do not apply oil-care or oil-maintenance products over the Traffic HD surface.
  • Avoid steam cleaners, strong household detergents and excessive water.
  • Do not damp mop the floor during the first three days after the final coat.
  • Do not cover the floor with rugs or protective floor coverings during the first three days.
  • Use suitable felt protection beneath furniture and avoid dragging heavy objects across the floor.

Important Information

Bona Traffic HD must be mixed accurately with its supplied hardener. Once mixed, the polyurethane lacquer has a limited working time and cannot be stored for later use.
