Preparations

Prior to application the surface must be pre-treated with a waterborne primer from Bona. Ensure floor is acclimatised to its end-use environment, well sanded, dry and free from sanding dust, oil, wax and other contamination. Allow lacquer to reach room temperature, insert filter and shake the container thoroughly before use. Optimal application conditions are between 18-25°C and 30-60% relative air humidity. High temperatures and low humidity shorten, low temperatures and high humidity lengthen drying time. Minimum temperature for use is 13°C.

Treatment Schedule

Untreated wood:
1x Bona Waterborne Primer
Light sanding grit 150
2x Bona Mega
NB: It is recommended to not apply more than two full coats per day due to increased risk of excessive wood swelling.

Application

  • 1. Apply the lacquer using a Bona Roller. Roll with a smooth flowing motion alternately across and with the grain of the wood avoiding accumulations of product. Always maintain a “wet edge” to avoid overlaps. Allow to dry before applying further layers of lacquer. Anticipate slightly longer drying time for each layer that is applied.
  • 2. If necessary make an intermediate sanding using a screen or the Bona Scrad System grit P150 (or finer) and remove dust before applying the final layer of lacquer. Note: If the previous layer of lacquer has been allowed more than 24 hours drying time then an intermediate sanding is always required.

The floor will take light foot traffic approximately 8 hours after the final application. Allow the surface to dry for at least 1 week before covering with carpets or other floor coverings, or loading with heavy objects. Also avoid damp mopping the floor during this time.

Maintenance

Clean the floor with Bona Cleaner or Bona Wood Floor Cleaner and a microfibre pad. For maintenance and upkeep of the surface, floors can be overcoated at intervals with additional coats of lacquer. The frequency of this operation can be greatly reduced if Bona Freshen Up or Bona Wood Floor Refresher is applied periodically. This will restore the appearance of a dull floor whilst still allowing further coats of lacquer to be applied without the need for sanding the floor back to bare timber.
NB: The use of adhesive tape can damage the dry lacquer.
