CONSUMPTION
Recommended Dosage
Add one part of Sika®-1 to 10 parts of water, which is equivalent to approximately 3 % of cement content. When using very wet sand, the ratio must be increased to 1:8 or in extreme cases 1:6.
Note: Trial mixes should always be conducted to establish the exact dosage rates and water requirements per mix.
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.
