Preparation of Substrate

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.

Application Method

The sealant should not adhere to the joint bottom; the use of a joint backing rod is recommended. The width and depth of the joint must not be less than 5 mm. In manual applications, the material is places in an application gun and injected into the joint without causing the formation of any air bubbles.
