Instructions

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 ten minutes. With a power mixer or a drill paddle, around one to three minutes of mixing is sufficient. Let the plaster 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. Every batch must be mixed in the same way. The finished plaster remains workable for around two to three hours.

The adhesive plaster (Fescon KS 10/90/600 or KS 35/65/500) must harden for at least one day before filling. If necessary, wet the base before applying the filler.

Apply the filling 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. Screed the filler plaster with a board. You can also carefully float the surface with a wooden tool to level the surface. Usage of dry plaster with a layer thickness of 15 mm
is approx. 30 kg/m². The lowest working temperature is + 5°C.

You can use plastering mesh to reduce the cracking risk caused by the drying of the plaster. You should in particular use a mesh at the joints of different materials, as reinforcement near openings and corners, and when plastering various block surfaces (Siporex, LECA, concrete).

A fill plastering should be given aftercare for at least three days. The aftercare must be begun as early as possible so that plastic cracks in the fresh plaster can be prevented.
