Preparation

Prior to application, the surface must be pre-treated with a waterborne primer from Bona. Ensure the floor is acclimatized to its end-use environment, well sanded, dry, and free from sanding dust, oil, wax, and other contamination. Allow the varnish to reach room temperature, insert the filter and shake the container thoroughly before use.

Optimal application conditions are between 18-25°C and 40-60% relative air humidity.

High temperatures and low humidity shorten, low temperatures and high humidity lengthen drying time. The minimum temperature for use is 13°C.

Application

1. Apply the varnish 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 drying before applying further layers of finish. Anticipate a 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 finish has been allowed more than 24 hours of 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 it with carpets or other floor coverings, or loading it with heavy objects. Also, avoid damp mopping the floor during this time.

Cleaning

Cleaning: Wipe tools free from excess varnish before cleaning with water. Dried material can be removed with acetone

Maintenance / Aftercare

Clean the floor with Bona Cleaner or Bona Wood Floor Cleaner and a microfibre pad.(These can be purchased together with a Bona spray mop). For maintenance and upkeep of the surface, floors can be overcoated at intervals with additional coats of varnish. 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 varnish to be applied without the need for sanding the floor back to bare timber.
