Bona R850 15kg Flexible Wood Flooring Adhesive

Ex. VAT: £72.50 Inc. VAT: £87.00

Availability: In stock

Product Advantages

R850 is an elastic 1-component silane adhesive for wooden floors.

The hardened adhesive is similar to conventional adhesives in its ability to withstand thrust during expansion, whilst having a low resistance to shrinkage. This means that tension to the subfloor is very low.

The adhesive hardens due to a chemical reaction with moisture.


Technical Spec
Open time: Approx 40mins*

Drying time, until: - Application of load: 24-48hrs*
*under normal climate conditions, 20°C/60% R.H.

Preparation

The substrate must be even, totally dry, clean, free from cracks and physically sound.

The surface should also be slightly textured.

 A primer is typically not needed.

Uneven floors should be levelled.

Suitable substrates (also in association with underfloor heating) are:

Cementitious screed (CT) according to EN 13813

Floors levelled with levelling compounds (at least 2 mm thick), resistant against plasticizer migration

Calcium sulphate screed (CA) according to EN 13813

Chipboard (V100)

Other dry and sound sub-floors

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 prefinished parquet should be slightly drier.

Solid wood parquet shall have therefore, in general, an average humidity of 9% whereas multi-layered and prefinished parquet shall have in average 8%.

Typical deviations from the average are +/- 2 %. Where doubts exist, avoid too dry material.

Note: Please also refer to the instructions for use provided by the parquet manufacturer.

Application

Before using the adhesive the following climatic conditions must be met:

Air temperature: min. 18°C

Floor temperature: min. 15°C (with underfloor heating max. 20 °C)

R.H: max. 70 %

The adhesive itself must, if necessary, be brought to the right temperature.

Apply with a or notched trowel

 

Cleaning

Cleaning:  Acetone or ethanol will remove but hardened adhesive can only be removed mechanically.

Storage / Shelf life
Shelf life: 1 year from date of production in unopened original container
The temperature must not fall below +5°C or exceed +25°C during storage. Store in cool, dry, well ventilated area.
