How To Apply Bona R880
Apply with cartridge gun
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 must, if necessary, be brought to the right temperature.
After opening the cartridge the required amount of adhesive is pressed out and applied to one of the substrates. The other substrate is pressed in during the open time of approx. 10 min.
Depending on initial load, it may be necessary to fix the parts in place until setting has occurred.
To accelerate the bonding process, water can be sprayed on the substrates or the adhesive (0,5 %, for e.g. 1000 g adhesive you need 5 g of water, the water can be mixed into the adhesive, open time can then be reduced to 5 minutes, lay in the substrates immediately). If on the sub floor applied adhesive has a skin, remove adhesive and apply new. If excess adhesive is exuded it should be carefully removed.
After 4 to 8 hours it is possible to apply load or stress, depending on temperature and humidity conditions.
