The surfaces must be solid, clean and dust-free. Carefully remove weak and loose material. Before applying the plaster, use water or Fescon Primer to wet dry and water-absorbent bases.


Refer to the package for how much water the plaster requires. Add the dry material to water and mix with a drill paddle or other suitable mixing tool for around one to two minutes. The finished plaster remains workable for around 20-30 minutes.

Spreading the filling plaster

Spread the plaster on the base either with a levelling spray or a steel trowel. If you are applying several layers of plaster, you can allow the previous layer to harden or double up using the wet on wet method. If necessary, the dried surface is ground after the application of each layer of plaster.

Spreading the levelling compound

Spread the levelling compound on the base either with a levelling spray or a steel trowel. You can recover and reuse any extra compound. When applying several layers of the levelling compound, allow the previous layer to harden completely before applying the next layer. Depending on the conditions, the hardening will take one to two days. If necessary, the dried surface is ground after the application of each layer of levelling compound.


Can be overlaid or waterproofed after around 24 hours. 

After treatment

In dry conditions, wet the levelled surface with a water spray.
