Application

Application Information

Mixing

Measure the required quantity manually or by automated dispenser. Add Sika® Air-260 directly to the mixing water or to the sand stream, do NOT mix with dry cement. Sika® Air-260 may be dispensed on-site directly prior to placement. Care must be taken to mix thoroughly. When used in combination with other admixtures dispense each admixture separately into the mix.

  

Compatibility: Sika® Air-260 can be used in combination with other Sika admixtures and can be successfully used in mix designs utilizing supplementary cementitious materials.
Consumption

Recommended Dosage

The typical dosage rate of Sika® Air-260 will vary between 0.1-6.0 fl oz / 100 lb. (7-400 mL / 100 kg) of cement or cementitious materials. Various factors will affect the dosage rates.

  

Trial mixes with the actual materials should be conducted to determine the required dosage for optimum performance.

  

To the extent specialized materials are used, extreme ambient temperatures are encountered, or for other unusual project conditions, dosage rates outside the typical range may be required. For dosage rates outside the typical range, please contact your local Sika representative or the Sika Technical Services Department at 1-800-933-7452.
