AS AN ACCELERATOR: Add to gauging water at an addition rate of 2.5 to 5 litres per 50kg cement depending on the degree of acceleration required. Note: remember to reduce required quantity of water accordingly.

AS A FROSTPROOFER: Add to gauging water at an addition rate of use 2.5ltrs/50kg cement for protection down to –4°C and 5ltrs/50kg cement for protection down to –8°C, again, reducing required quantity of water accordingly.
