Bona - experts in wooden floor care since 1919

Bona AB is a family-owned company founded in 1919. With its headquarters in Sweden, Bona is now present in more than 70 different countries all over the world through subsidiaries and distributors.

They provide products for the installation, maintenance and renovation of wooden floors throughout their lifetime. Today they have solutions for professionals, homeowners and parquet producers.

Great concern for the environment 

Bona has great concern for the ones working with their solutions, living and enjoying them, and the environment affected by their actions and products, today and tomorrow.

They strive to continuously launch better products with less environmental impact. This has led to breakthrough innovations from waterborne finishes in the 1970s to dust-free sanding in the 2000s. Today, they are proud to be able to offer a full range of environmentally sound products for sanding, finishing, fastening and maintaining a wooden floor – throughout its lifetime.

Preparations:

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

Minimum temperature for use is 13°C.

Preparation of previously varnished floors

Bona Traffic can be used for overcoating factory pre-finished and previously varnished floors but satisfactory adhesion must be secured prior to use!

Floors treated with wax, polish or similar cannot be over coated. Suitable surfaces are pre-treated with Bona Prep before coating. A detailed overcoating instruction is available for download at www.bona.com.

Application:

1. Add 10% Traffic/Flow Hardener to the varnish and immediately shake the mixture thoroughly, for 1 minute. The mixture of varnish/hardener should be used directly or at least within 4 hours.

2. 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 to dry properly before applying further layers. Anticipate slightly longer drying time for each layer that is applied.

3. If necessary make an intermediate sanding using a screen or the Bona Scrad System grit P150 (or finer) and remove dust before applying a final layer of varnish. Note: If the previous layer of varnish has been allowed more than 24 hours drying time then an intermediate sanding is always required.

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 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.
