Bona Traffic surface preparation
Care should be taken at all times to ensure that surfaces to be coated have been well sanded and are free of all contaminates including sanding dust, grit, dirt, oil, wax and any other contaminates. The final stages of sanding should be done with a sanding disk, screen or good quality sandpaper with a paper grit of 120 of finer.
General conditions to determine if an overcoating of Bona Traffic is possible
- Surfaces must be completely clean
- Floors pre-treated with waxes, polishes or other similar products cannot be overcoated with Bona Traffic
- Always treat a small test area prior to the main application
- Bona will not guarantee good adhesion when overcoating varnish finishes of a brand other than Bona
Bona Traffic HD will normally have very good adhesion to pre-varnished flooring, this said however, it is advisable to check the intercoat adhesion prior to overcoating. To check intercoat adhesion, apply a coat of Bona Traffic HD to a pre-prepared area. Allow the coating to set for 3 days then scratch the treated floor surface gently with a coin, if the Bona Traffic finish stays firmly attached to the surface, the adhesion is satisfactory and the main application can begin.
Always thoroughly read the manufacturers guidance and instructions on the container or tin including any mixing and usage instructions on associated products.
Before applying Bona Traffic HD, it is important that the container is shaken thoroughly prior to use, this also applies if the product is to be split into other containers in smaller quantities. Add 10% Traffic Hardener to the finish and shake immediately for a minimum of 1 minute to ensure a thorough mix of the finish and hardener.
Once the hardener has been added to the Bona Traffic finish, the mixture of finish and hardener should be used within 5 hours at a temperature of around 20C, high temperatures will reduce the usability time of the mixed product.
- On bare wood: 1 coat of Bona Prime Classic plus 2 coats of Traffic HD, or 3 coats of Traffic HD without Priming
- Overcoating : 1-2 coats of Bona Traffic HD
Bona Traffic is best applied with a roller and with a smooth flowing action, care should be taken to avoid accumulations of the finish on the floor, room application and drying temperature must not fall below 13C.
An average drying time of 3-4 hours at 20 degrees / 60% RH
