Sika® PerFin-305

CONCRETE SURFACE ENHANCING ADMIXTURE

Sika® PerFin-305 is a liquid, non-chloride-based concrete admixture used to improve finished concrete surfaces. Sika® PerFin-305 reduces surface defects of the concrete surface.

When used in concrete mixes, Sika® PerFin-305 significantly improves the quality of concrete surfaces by reducing the amount of pinholes, open pores and other surface defects. Sika® PerFin-305 provides the following advantages:
  • Concrete with minimum surface defects
  • Improved concrete durability
  • Improved aesthetics and uniformity of concrete surfaces
  • Improved concrete smoothness
  • Reduced risk of rejection due to surface quality related issues
  • Reduced labor needed for surface patching
  • May be used in reinforced and prestressed concrete
  • Does not promote the corrosion of steel reinforcement

Application Information

Compatibility

Sika® PerFin-305 is compatible with majority of Sika admixtures, however, each admixture should be added separately to the mix. Sika® PerFin-305 can be used in mixes containing supplementary cementitious materials such as slag or flyash. It is always recommended to verify actual performance by conducting trial batches.

Mixing

To achieve best performance, add Sika® PerFin-305 into the mixing water. It is possible to add Sika® PerFin-305 directly to freshly mixed concrete in the concrete mixer at the end of the batching cycle. To achieve proper dispersion of Sika® PerFin-305 throughout the entire concrete volume, mixing time of minimum 90 seconds is recommended.

Note: Use personal protective equipment (chemical resistant goggles / gloves / clothing) to handle product. Without direct contact, remove spilled or excess product and place in suitable sealed container. Dispose of excess product and container in accordance with applicable environmental regulations.
Consumption

Recommended Dosage

Recommended dosage will be typically between 0.2–0.5 % by weight of cementitious material (195 to 490 mL /100 kg of cement). The effectiveness of Sika® PerFin-305 depends on concrete mix design, cleanness of form work and form release agent.
