Bona R848 Adhesive. Perfect for installing parquet flooring or narrow solid boards (less than 190mm width). Suitable substrates include concrete, plywood, cork, particle or chip board, stone, ceramic, terrazzo, radiant heat flooring (refer to manufacturer's recommended installation instructions) and dry, above-grade gypsum underlayments. This product may be used for glue assisted installations. Excellent initial "green grab" means the flooring stays in place, causing practically no swelling of the wood. With it's GreenGuard indoor air quality certification, it's water and solvent-free, meaning no strong odours.

The substrate must be structurally sound, clean, dry and free from surface dust, dirt and debris. Surfaces should be slightly textured for best adhesion. Substrates may need to meet the requirements of local standards and codes of practice before floors are laid. It may be necessary for substrates to be professionally prepared for laying.
Please Note: Wood flooring must not be installed before the compound has fully cured. Do not install over expansion joints or other moving joints in a concrete slab.
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.
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
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.
