Sika® PerFin-305

CONCRETE SURFACE ENHANCING ADMIXTURE

Sika® PerFin-305 is a formulated liquid concrete admixture used to improve finished concrete surfaces. Sika® PerFin-305 reduces surface defects of the concrete surface. Sika® PerFin-305 meets the requirements of ASTM C494, Type S admixture.

Sika® PerFin-305 significantly improves quality of the concrete surface. The amount of pinholes, open pores and other surface defects are reduced when Sika® PerFin-305 is utilized in concrete mixes.    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.

Usage

Sika® PerFin-305 is recommended for use in cases when concrete with minimum surface defects is required or whenever high architectural and aesthetic requirements are desired.     Sika® PerFin-305 can be used for:
  • Structural concrete
  • Precast / prestress concrete
  • Architectural concrete with high aesthetic demands
  • Concrete with high requirements on surface quality
   Sika® PerFin-305 is a non-chloride based concrete admixture. Sika® PerFin-305 does not promote the corrosion of steel reinforcement. Sika® PerFin-305 can be used in reinforced and prestressed concrete. Sika® PerFin-305 is not recommended for use in air entrained concrete.

Application

Application Information

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. Sika® PerFin-305 should not be dispensed directly onto cement, slag or fly ash.

   

Combination with other Admixtures: Sika® PerFin-305 can be used in combination with other Sika admixtures. It is always recommended to verify actual performance by conducting trial batches. Please contact your local regional office or technical service department at 1-800-933-7452 for further assistance.
Consumption

Recommended Dosage

Recommended dosage rates will be typically between 0.2–0.5 % by weight of cement or (3.0 to 7.5 fl.oz/100 lbs of cementitious materials). The effectiveness of Sika® PerFin-305 depends on concrete mix design, cleanness of form work and form release agent.

   

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.
