- Apply grout with a dedicated pump or pour it freely, ensuring that the flow of grout is maintained continuously.
- To reduce the initial heat of hydration, cold water can be used to mix the mortar or use flint with a particle size of 1.7 - 5.0mm to add to the fresh mortar mixture. The flint used should be washed, drained and put into the mixing tank when the mortar mixture has been uniformly mixed. Concentration of flint used from 50 - 100% compared to the volume of dry mortar.
