Tyfo® CIS Inhibitor Layer 2
DESCRIPTION
Tyfo® CIS Layer 2 is a single-component, clear, waterbased liquid with a mild odor. It may be
applied by roller or spray following the application of Tyfo® CIS Layer 1. Layer 2 controls the pH,
purges and encapsulates water-soluble chlorides, fills voids in the concrete, and inhibits further
penetration of moisture. Layer 2 also acts as a contact corrosion inhibitor on the reinforcing steel.
After receiving both Layers 1 & 2, the exposed surfaces are cleaned by washing with fresh water or
by abrasive blasting. All exposed steel is then treated with the Tyfo® CB material and the concrete
section is restored using Tyfo® P or Tyfo® PF as required.
USE
Tyfo® CIS Layer 2 is used with the Tyfo® Concrete Repair System on new or old concrete surfaces
to seal porosity, increase compression strength, maintain pH, protect from acid and alkali attack,
pacify and extract chlorides, and inhibit embedded steel corrosion.
ADVANTAGES
• Ease of application
• Can be applied to horizontal, vertical or
overhead surfaces
• Restores properties of deteriorating Portland
concrete cement
• Can penetrate concrete 2 to 3 inches,
depending upon existing porosity
• Dramatically improves condition of
substrate prior to repairs
• Protects new concrete
• For new and old structures
• Non-toxic
