The joint or area being concreted over must be undamaged, clean, and damp enough to be darker in colour. If necessary, remove the weak-strength cement paste layer. Best adhesion can be achieved to a rough base. The joint width must be sufficient (at least 15 mm) so that the casting mass fills the joint entirely.


Refer to the bag for how much water the concrete requires. Add the dry material to the water and mix with a concrete mixer for around ten minutes. With a power mixer, around one to three minutes of mixing is sufficient. Let the mass stand for a while and mix it again for a short while. Find the correct consistency at this stage by gradually adding the rest of the water. We do not recommend adding all of the water right at the start. If you are unable to use the concrete immediately after mixing, we recommend mixing it again before casting. The finished concrete remains workable for around one hour.

Work instructions

Pump the mass to the casting location using either a screw or piston pump. When adjusting the pump output, take the joint thickness and prevailing conditions into consideration. The concrete has the correct amount of water when the pumped mass does not flow out of the joint. Level the joint that was cast with a steel trowel. Cast a joint that is open to both sides by blocking one side of the joint with a stopper board. Remove the board a while after pumping, once the concrete has hardened somewhat. Finally, level the joint surface on the side of the board with a trowel. Vertical grouting concrete is not vibrated.

After treatment

If the temperature falls below -15°C, you must prepare to take protective measures.
