PREPARATION Ensure floor is acclimatised 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 conditions for use 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.


Standard protocol: Previously lacquered surfaces: 1 x Bona Primer1 Cleaning and superficial abrasion 2 x Bona Traffic HD1 1-2 x Bona Traffic HD

For colouration: 1 x Bona Craft Oil 2K2 2 x Bona Traffic HD 1

the surface should receive three coats in total. 2 to minimise the potential for oil bleed back, it is advised to be restrictive with the application rate. Using a cloth wrapped around a pad under a buffing machine for application helps maintain the oil at the surface.

Observe: It is not recommended to apply more than two full coats of primer and/or lacquer per day due to risk of excessive wood swelling. Ensure good ventilation during drying. Poor drying conditions may reduce product performance and adhesion.


1) Shake the lacquer can and add the hardener component. Immediately proceed to shake the mixture carefully for one minute. Use the mixture directly or at least within four hours. If mixing smaller quantities of lacquer, then one section on the hardener bottle corresponds to 1 litre of lacquer. 2) Apply using a Bona Roller at 8-10m2 /litre (100-120g/m2 ). Roll alternately across and with the grain of the wood avoiding accumulations of product. Always maintain a “wet edge” to avoid overlaps.

3) Allow to dry properly before applying further layers. Ensure proper ventilation.

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

Floor will take light foot traffic approximately 6 hours after the final application and may be put into full use after 12 hours. Allow the surface to dry for at least three days before covering with carpets or other floor coverings. Also avoid placing heavy objects or damp mopping the floor during this time. Note: If Traffic HD has been combined with Bona Craft Oil 2K then the surface must be allowed to cure for one week before the surface is covered.

• Plasticisers found in materials such as carpet underlays, furniture legs, castors and adhesives used for fixing can lead to softening and discolouration. Exposure to hair dyes or rubber tyres on cars, cycles and baby strollers can lead to permanent discolouration of the surface. Use protection or completely avoid contact.

• Spills should be removed promptly. Unattended spills may cause cosmetic stains or damage the surface. Please note that whilst Bona lacquers are designed to provide a sealed surface that is resistant to wear, scuffing and spillage, etc. No surface applied finish system can prevent physical damage to the timber or “harden” the floor. Indentations in the wood and scratches may be caused by furniture, dropped items, dog claws, etc. and steps should be taken to reduce the possibility of this occurring.
