Instructions

Preparation:
Clean the substrate carefully and if possible pre-water 24 hours before casting. Remove surface water immediately before casting.

Mixing:
Do not mix by hand. The best mixer is a rapid mixer type Rojo 50, automatic mixer or flat mixer. For smaller quantities, mixing with a drill and mixer attachment works well. Mix to an even and clump-free consistency. Always pour in the water first. Use a graduated mixing vessel and ensure that the temperature of the mix is 20°C. The mixed concrete must be used within 20 minutes.

Jointing:
The mix is pumped into the joints with a Bemix concrete pump. Smaller quantities can be applied manually into the joint with a Bemix concrete injector.

After treatment:
Concrete that needs to be removed is scraped off with a finishing trowel once it has hardened sufficiently. Visible surfaces in the joint are shaped to the required appearance.

After curing:
When after treatment is done protect free surfaces from drying out. Apply a water mist and protect with plastic sheeting. Keep damp for the whole first week. Sub-zero temperature: after-watering should not be done if applying in sub-zero temperatures.
