Base
Clean the base of loose dust and dirt. Remove cement paste from concrete surfaces. Wet the dry base until it darkens. The best time to wet the surface is the previous night.
Mixing
Refer to the bag for how much water the plaster requires. Add the dry material to the water and mix with a concrete mixer for around five minutes. With a power mixer or a drill paddle, around one to two minutes of mixing is sufficient. Allow the plaster to stand for around ten minutes 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. The finished plaster remains workable for around two hours.
Casting
Apply the plaster to the casting location that is damp enough to be darker in colour, and compact carefully. In floor surface casting, the old base can be reinforced with plastic dispersion spread on a dry surface.
Plastering
In plastering, the plaster is slammed into a surface that is damp enough to be darker in colour. Recommended layer thickness is around 20 mm.
After treatment
You must care for the fresh casting and plastering surface by spraying with water and/or protecting it with a plastic film. The need for aftercare depends on the conditions. It should continue for at least one to three days.
