Surface Preparation

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.

Joint design

The sealant should not adhere to the joint bottom; the use of a joint backing rod is recommended. It is advisable
to effect preliminary adhesion tests. If the joint has a concrete protective system the compatibility of the joint coating with the sealant has to be verified.
