Always do a test area before starting any project to check suitability and compatibility, following the manufacturer's instructions on the container at all times.
Before use, ensure the air temperature is above 18°C, the floor temperature is above 15°C (with under floor heating max 20°C) and the relative humidity is less than 70%. If necessary, bring the adhesive to the right temperature.
- Once opened, remove the protective foil and any hardened adhesive from around the edges
- Spread adhesive on the substrate while holding the Bona trowel at a 90° angle, using a smooth semi-circular motion
- Once applied, if the adhesive has formed a skin, remove the adhesive and re-apply
- Do not allow more than 30 minutes of open time before firmly setting flooring into the adhesive. Higher humidity can decrease open time
- If some adhesive is pressed up in joints (so that it might come into direct contact with a finish or oil), remove it carefully or make sure that the adhesive is sufficiently cured before you apply the surface treatment
- Do not leave any puddles of adhesive
Use a fine trowel for small pieces of wood and/or smooth substrates, and a coarse trowel for large pieces of wood and/or less smooth and rough surfaces (F = fine, G = coarse) Bona Adhesive Trowel
- Mosaic parquet or any other similar solid parquet: approximately 900 g/m², Bona Trowel 850 G or 850 F
- 2 layered pre-finished parquet and 22 mm block parquet: approximately 1100 g/m², Bona Trowel 1000 F or Bona 1000 G
- 3-layered pre-finished parquet, boards and solid wood planks (max. 22 x 120 mm): approximately 1350 g/m², Bona Trowel 1250 F or 1250 G
The adhesive consumption during the application with the Bona OptiSpread system
depends mainly on the walking speed as well as the adjusted air pressure (OptiSpread
100, OptiSpread 2.0). Please refer to respective machine manual.
For full application and coverage details, please refer to the 'Technical Information' Datasheet link above.
It is possible to apply load and stress to the floor after approximately 24 to 48 hours. Any sanding and surface coating to be applied, may be carried out after 1 to 4 days depending on the type of parquet, absorbency of the substrate and room climate.
