Pro Tips

  • **Surface Preparation**: Proper surface preparation is critical - clean, dry, and repair all defects before application.
  • **Moisture Testing**: Test substrate moisture content - waterproof coatings require dry surfaces for proper adhesion.
  • **System Selection**: Choose coating systems appropriate for exposure conditions and performance requirements.
  • **Quality Control**: Implement proper quality control measures including thickness testing and holiday detection.
  • **Weather Conditions**: Apply only in suitable weather - avoid rain, high humidity, or extreme temperatures.
  • **Penetration Sealing**: Properly seal all penetrations and details - these are common failure points.
  • **Professional Application**: Waterproofing is critical work - use experienced, certified applicators for best results.
