MIXING

Stirrer (400-500 rpm)

Pour the appropriate amount of water into a suitable and clean mixing container. While stirring slowly, first add half the package to the water and mix for approx. 30 seconds. Then add the remaining amount of powder and mix for a further 150 seconds (2 minutes and 30 seconds) until a homogenous and lump-free consistency is achieved. Do not exceed the recommended maximum amount of water. It is then recommended to deaerate the grout for approx. 1 - 2 minutes before pouring. Only mix complete bags.

Compulsory mixer

Pour the appropriate amount of water into a suitable and clean compulsory mixer. While stirring slowly, add the entire package into the water and mix for at least 3 minutes until a homogeneous and lump-free consistency is achieved. Do not exceed the recommended maximum amount of water. It is then recommended to deaerate the grout for approx. 1 - 2 minutes before pouring. Only mix complete bags.

 

APPLICATION

SikaGrout®-580 must be poured slowly and continuously from one side in order to avoid air inclusions. Feed pumps are recommended for the use of large quantities. Preliminary tests with the appropriate pumps should be considered to ensure that the product can be pumped sufficiently. Do not add additional water to the surface after pouring. The formwork should not be removed until the concrete has cured. Winter construction should be considered if temperatures fall below +5°C.

CURING TREATMENT

Protect exposed grouted surfaces immediately against early water evaporation (wind, draughts, sunlight, etc.) for a period of 3 to 5 days.

CLEANING OF EQUIPMENT

The mixing and application equipment must be cleaned with water immediately after use. Cured material can only be removed mechanically.
