Mix the product thoroughly prior to application. It can be applied with a brush or roller. It can also be applied using a spray gun.


Work should be done under dry conditions at air and base temperature from +5°C to +30°C and at foreseen lack of precipitation during bounding. The bounding time depends on the air temperature and relative air humidity (for relative humidity at the level of 65% and air temperature at ca. 20 °C, the proper coating will dry up for maximum 6 hours). The temperature rise and air humidity drop influence on shortening the bounding time. The temperature drop and humidity increase may elongate the bounding time several times.

To avoid damaging the insulated surface e.g. during backfilling or land sliding, it is necessary to wait until the insulation complete drying occurs and to apply proper draining boards or other shields.


Work should be done according to the Occupational and Health Safety rules resulting from the material safety data sheets (MSDS) and package labelling.
