How to Use

1. Select the required quantity for the cement content of the mix.
2. Follow Sika's published recommended dosage: 0.5kg per two 50kg bags of cement, equivalent to 100kg of cement. The reference also lists 0.43L for this dosage; because that volume does not align with its stated density, confirm volume-based dosing with Sika before use.
3. Dispense the liquid directly into the mixing water before adding the aggregates.
4. Follow the current Sika Product Data Sheet and the specified concrete mix design for mixing, placing, compaction and curing.
