APPLICATION STEPS

Mixing
Sika®-1 must be stirred slowly before use to ensure a homogeneous, lump free consistency.

Sika®-1 shall be diluted in the gauging water. The dilution must be stirred slowly (to ensure a homogeneous, lump free consistency) prior  addition into the mortar/concrete mixer. Sika®-1 can also be added neat to the mortar/concrete mix provided that the mixture is properly mixed to achieve a homogeneous consistency.
