Sika® PerFin-305

SURFACE ENHANCING AND AIR DETRAINING ADMIXTURE

Sika® PerFin-305 is a concrete admixture formulated to enhance finished concrete surfaces and/or reduce the air content of concrete. Sika® PerFin-305 meets the requirements of ASTM C494/AASHTO M 194, Type S.

Sika® PerFin-305 is formulated to provide a concrete surface free of open pores and other surface defects. Sika® PerFin-305 also provides:
  • Improved aesthetics and uniformity of concrete,
  • Improved concrete durability,
  • Reduced risk of concrete rejection due to surface quality related issues,
  • Reduced labor required for surface patching.
Sika® PerFin-305 can also be used for the purpose of reducing the total air content of concrete. In non-air entrained concrete mixes, Sika® PerFin-305
can be added to minimize undesired air content. In air entrained concrete mixes, Sika® PerFin-305 canbe used two ways. It can be used to reduce the total air content to meet the project requirements or it can be used prior to the addition of a standard air entraining
admixture. When used in air entrained concrete mixes, it is recommended to perform trial evaluations to verify the quality of the air-void system and to ensure the concrete meets the plastic and hardened project requirements.
Sika® PerFin-305 does not contain intentionally added chlorides.

Usage

Sika® PerFin-305 is recommended for use when concrete with minimum surface defects is required or whenever high architectural and aesthetic requirements are desired or a reduction of air content is needed. Sika® PerFin-305 can be used for:
  • ƒƒStructural concrete
  • ƒƒPrecast / prestress concrete
  • ƒƒArchitectural concrete with high aesthetic demands
  • ƒƒConcrete with high requirements on surface quality

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.

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.In cases when Sika® PerFin-305 is stored in bulk tanks, periodic checks of dispensing lines are recommended to prevent product leakage. Use only oil resistant gaskets and hoses. Sika® PerFin-305 may cause deterioration of rubber.

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.
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.
