Mix with a concrete mixer for around ten minutes; two to three minutes are sufficient with a power mixer. Let stand for ten minutes, and mix again for a short while. When using an automatic mixer, ensure that the amount of water does not get too high.

Work instructions

Apply the plaster with a plaster trowel or a pump. A suitable thickness for one layer of filler is around 15 mm. If the layer thickness exceeds 20 mm, the filler must be applied in several layers so that the previous layer has had time to dry for one to two days before the next layer is applied.

In dry conditions, the base must be wetted before applying a new layer of plaster. The lowest usage temperature is +5oC.

After treatment

A fill plastering is given aftercare depending on the conditions for around three days. The aftercare must be begun as early as possible so that plastic cracks in the fresh plaster can be prevented.
