Can Radcon be applied where other sealer materials have been used previously?

Obviously any material designed to repel water off concrete will also repel Radcon preventing penetration and ultimate waterproofing reaction from taking place.
Ensure all previous failed materials are completely removed. If cracks have been contaminated by previous materials they may require an arrow head grind, Radcon application and non-shrink grout emplacement.
