All surfaces must be perfectly clean, dry and free from dust and grease. Where necessary apply a coating of primer on the joint walls. Use PU 101 A for porous (absorbing) surfaces like concrete, mortar etc.

In manual applications, the material is places in an application gun and injected into the joint without causing the formation of any air bubbles.
