Application advice:
The surfaces of the joins should be clean and free of dust, damaged concrete, grease or other contaminants that could impair adhesion. Pre-water for at least 24 hours. Remove surface water immediately before casting. Rough surfaces give better adhesion. The concrete is applied manually and carefully packed. The concrete can also be pumped with a purpose-designed concrete pump. Ensure that joints and underpourings are always completely filled so as to avoid cavities.

Mixing is done mechanically for approximately 5 minutes in a slow-action mixer, such as a flat or free-fall mixer. Smaller quantities can be mixed with a mixer attachment. The concrete mix should have a temperature of approximately 20°C. Compensate cold dry material with warm water and vice versa. Watering should not be done if applying in sub-zero temperatures.

After treatment:
Semi-hardened material can be adjusted with a finishing trowel. Free and undamaged surfaces should be treated immediately after casting with a thin, light misting of water that cannot mechanically damage the material. As soon as it is hard, water carefully and cover with plastic. Keep the concrete damp for at least a week after application and try to keep an even temperature of 15˚C while it is curing. Sub-zero temperature: after treatment should not be done if applying in sub-zero temperatures. Winter application: The mix hardens and cures without heating even if the temperature of the mix itself drops well below 0 °C.
