Application Work should be carried out in accordance with the methods outlined in the Code of Practice BS5628 Part 3 for protection and use of mortars at low temperatures. All materials used must be free from ice and the temperature of the mix prior to placing must not be less than 4°C.

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.

AS A PLUGGING AID: Mix neat with fresh cement and place immediately. NOTE: Concrete must be covered after placing until the minimum strength is obtained or until the temperature rises above freezing. Do not use with high alumina cement. Following is an indication of setting times at 20°C (use as a guide only)
