Ensure the floor is acclimatised to its end-use environment. The surface must be sanded back to bare wood, dry and free from sanding dust, oil, wax and other contamination. Sanding with a 120 grit abrasive using a Bona Quattro Disc, or similar equipment is recommended for the final sanding of the wood. Allow the product to reach room temperature. Optimal application conditions are between 18-25°C and 30-60% relative humidity. High temperatures and low humidity shorten, low temperatures and high humidity lengthen drying time. In dry and/or warm conditions max. 4% Bona Extender may be added to prolong the open time and reduce the risk of overlapping and discolouration. Minimum temperature for use is 13°C. Observe: Tropical wood species such as Teak, Ipe, Wenge and similar species as well as some softwoods, contain natural ingredients – tannins, oils, resins and minerals, which can lead to significant lengthening of the drying time, wetting issues or colour changes. The same applies to heat- or chemically treated wood. It is strongly recommended that the timber species is identified, and a trial application carried out to assess the colour and general appearance of the system.
