Primer for untreated surfaces: Apply Kiesol (1:1 with water) without pressure and avoiding nebulisation moving
horizontally along the surface from top to bottom. Proceed by priming one limited area at
a time. Immediately remove the product in excess. All follow-up working steps must be carried out wet-on-wet.


Pour water into a clean container and add dry mortar. Mix thoroughly with a mixer for approx. 3 minutes until homogeneous. Maturing time approx. 2 minutes. Mix again and, if needed, add a small quantity of water.


  • Conditions for use: Temperature of the material, air and substrate: from min. +5°C to max. +30°C Low temperatures increase, while high temperatures decrease the working and setting time.
  • Working time (+20°C): Approx. 30 minutes
  • Bonding layer: Apply product in a grouting consistency as a bonding layer.
  • Levelling: Apply product in a filler consistency to the wet bonding layer. The following layer is applied as soon as the preceeding one can no longer be damaged.
  • Grout waterproofing according to PG-MDS: Immediately after mixing, apply the material making sure the entire surface is covered.
  • Surface waterproofing: Apply two layers for waterproofing against ground damp. Apply three layers for waterproofing against water pressure. The following layer is applied as soon as the preceeding one can no longer be damaged.
  • Horizontal waterproofing in and below walls: Apply the material in two layers on the previously prepared substrate. The following layer is applied as soon as the preceeding one can no longer be damaged.
