Little Tree Bali - Green Building Centre

• Rapid initial bonding strength 
• Water and solvent free, nearly no swelling of the wood 
• Good adhesion to almost all substrates and timber materials 
• Splashed material can be easy removed
• Firm texture – retains trowel pattern 

Preparation

The substrate must in general be even, totally dry, clean, free from cracks and physically sound. The surface should also be slightly textured. If applicable, it must meet the requirements of local standards or codes of practice. If necessary it should be professionally prepared for laying. A primer is typically not needed. If the sub floor is problematic the use of a primer like Bona D501, R410, R540 or R580 can improve it. A broadcasting of sand into Bona R410 can be omitted, if the surface stays clean and the parquet is glued with R848 within 24 h. Uneven floors should be levelled with Bona H600, H610 (filling of holes), H660 or H670. Suitable substrates (also in association with under floor heating) are :

• Cementitious screed (CT) according to EN 13813
• Floors levelled with levelling compounds (at least 2 mm thick, resistant against plasticizer migration) 
• Calcium sulfate screed (CA) according to EN 13813 
• Chipboard , OSB board 
• Other dry and sound sub floors 
• Mastic asphalt screed (AS) according to EN 13813 and other sub floors which are affected by migration of plasticizers must get a protective layer of Bona R410 or Bona R540

Application:

Before using the adhesive the following climatic conditions must be met (values for Central Europe): 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. After opening the bucket remove the protective foil and hardened adhesive at the edges. 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. 30 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 prefinished parquet should be slightly drier. E.g. in Central Europe average room conditions of 20°C and 50 % relative air humidity can be expected. Prefinished parquet shall have in average 8 %. Typical deviations from the average are +/- 2 %. Where doubts exist, avoid too dry material. Please also refer to the instructions for use provided by the parquet manufacturer.
