• rapid installation
  Wabo SiliconeSeal is a two-part cold applied, self-leveling,
  ambient cure sealant assuring ease in installation and
  providing minimal downtime in the field.
• Versatility                                                       Figure 2: Armored Condition
  Suitable for concrete, steel, aluminum or Wabo Crete II
  elastomeric concrete header applications, while allowing
  multidirectional movements of the structure.
• Unique Design
  Designed to provide a watertight seal and minimize
  debris, the Wabo Silicone Seal will easily bond to itself.
  No priming of interfaces is required which simplifies and
  accelerates the installation process.
