Bona R850 Flooring Adhesive

Bona R580 is an elastic one-component silane-based adhesive for parquet floors. It is water and solvent-free and causes practically no swelling of the wood. Firm texture – it retains the trowel pattern. Available in a 600ml ‘sausage’ pack, Bona R850T is a high viscosity adhesive made for gun application. Rapid setting, the hardened adhesive has a firm texture and can be used on nearly all sub floors. Suitable for underfloor heating.

Coverage:Usage approximately 850 g/m2. Mosaic parquet and similar 1 layered prefinished parquet.


  • 1-component, easy to handle
  • soft elastic
  • water and solvent free, nearly no swelling of the wood
  • wood adhesion to almost all substrates and timber materials, splashed material can be easy removed
  • firm texture – retains trowel pattern.


The adhesive should be applied evenly using a notched trowel appropriate to the flooring being laid (see below). The parquet should be laid on the adhesive and pressed down firmly during the open time, approx. 40 minutes. If on the sub floor applied adhesive has a skin, remove adhesive and apply new. If some adhesive is pressed up in joints (so that it might come into direct contact with the finish) it must be carefully removed. Depending on the expected average conditions the parquet needs, for the best adhesion, the correct moisture content of the wood to be selected. Solid wood parquet should be slightly more humid whilst multi-layered or pre-finished parquet should be slightly drier.

Drying Time

Sanding and the application of a surface coating may normally be carried out after after 12-24 hours. After 24-48 hours it is usually possible to apply load or stress to the floor.

The drying time depends on the type of parquet, the absorbency of the substrate and the climate conditions.
