APPLICATION METHOD / TOOLS
As an Accelerator: Add to gauging water at a rate of 2.5 to 5L per 50kg of cement, depending on the degree of acceleration needed. Remember to reduce the total water required accordingly.
As a Frostproofer: Add to gauging water at a rate of 2.5L per 50kg of cement for protection down to -4°C, or 5L per 50kg of cement for protection down to -8°C. Again, reduce the required water quantity accordingly.
As a Plugging Aid: Mix neat with fresh cement and place immediately.
Concrete must be covered after placement until it reaches minimum strength or the temperature rises above freezing. Do not use with high alumina cement.
LIMITATIONS
