Preparation
Prior to application the surface must be pre-treated with Bona Sportive Primer. Ensure floor is acclimatized to its end-use environment, well sanded, dry and free from sanding dust, oil, wax and other contamination. Allow lacquer and hardener to reach room temperature, insert filter and shake the container thoroughly before use.
Optimal application conditions are between 18-25C 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 13C.
Application
- Add 2% Sportive Hardener to the lacquer and immediately shake the mixture thoroughly, for 1 minute. The mixture of lacquer/hardener should be used directly or at least within 5 hours.
- Apply the lacquer using a Bona Applicator Bar or a Bona Roller. Roll with a smooth flowing action avoiding accumulations of lacquer. Always maintain a “wet edge” to avoid overlaps.
- Allow to dry properly before applying further layers of lacquer or paint. Anticipate slightly longer drying time for each layer that is applied. Ensure good ventilation at all times during the drying process. 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 lacquer. Note: If the previous layer of lacquer 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 but the floor should be allowed 72 hours drying before being taken into use. Allow 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 Sportive Cleaner (frequent use) and Bona Sportive Cleaner Plus (for periodic, intensive cleaning if the surface has become slippery). To uphold a safe and professional looking surface, and to avoid having to sand back to bare wood again, the floor should should be overcoated at intervals with additional coats of Sportive Finish. The frequency of this operation depends on the level of wear but would typically be between every 1-3 years.
NB: The use of adhesive tape can damage the dry laquer.
