Sika® PerFin-2

Concrete surface enhancing admixture

Sika® PerFin-2 is a liquid concrete admixture for reducing entrained and entrapped air, resulting in improved concrete density and off-form finish.

With the application of Sika® PerFin-2, entrained or entrapped air is significantly reduced. Sika® PerFin-2 provides the following advantages:
  • improved concrete off-form finish
  • improved concrete density and durability
  • enhanced concrete smoothness
  • no negative effects on the fresh or hardened concrete properties
The performance of Sika® PerFin-2 is affected by concrete mix design, fresh concrete properties and mould release agent.
