Trade Professional Information

  • Required Tools: Sealant gun, backing rod (if necessary), tooling agent, masking tape, cleaning cloths.
  • Trade-Specific Tips: Ensure thorough substrate preparation for optimal adhesion. Use appropriate primers for critical, high-performance applications. Tool the sealant firmly against the joint sides to avoid air entrapment. Allow sufficient curing time before exposing the joint to moisture or stress.
  • Common Issues and Solutions: Avoid using Hi-Flex 50 in totally confined spaces as it requires atmospheric moisture to cure. For applications on stone, always conduct a stain test beforehand. Avoid contact with uncured sealant with materials containing cleaning agents, solvents, and alcohol, as these may affect or discolour the sealant.
