Instructions
Pre-treatment:
Damaged concrete or rock is removed mechanically. Oil and other contaminants are removed with a cleaning agent. Final cleaning is done with the correct quantity of water. Very rough surfaces give the best adhesion. The surface should dry enough to be slightly absorbent when spraying.
Mixing and application:
Intended for the dry spraying method. Mixed and sprayed with appropriate equipment. Professional experience and knowledge of spraying concrete is needed. Always use clean water. Winter measures should be taken below 5°C.
