Shelf Life : 12 Months, in unopened packaging. After use close the open packaging well.
Application temperature : From 10° to 25 °C (surrounding and subfloor temperature).

* The mentioned values have been established in our laboratory and must be considered as guidelines in view of possible variations in climatic circumstances, subfloor compositions and layer thickness.

Approx. 1.5 kg/m² per mm layer thickness.

  • 658 Wandoforte can be applied on any type of cement-based subfloor that is rigid and has a good tensile and compression strength. The subfloor should also be clean, dry and free from grease and dirt. 
  • In advance degrease impervious subfloors e.g. old wall tiles with 014 Euroclean. Thereafter dry completely.
  • Prime smooth and impervious walls with 051 Europrimer Quartz (indoor application).
  • First remove loose paint and lime residues. 
  • PRime porous walls with 099 Dispersion Primer. 
  • Fill holes and cracks in advance. 
  • In advance always seek our technical data sheets. In doubt about the application ask for technical advice. 

User manual:
  • Add 25 kg of 658 Wandoforte to 6 litres of cool and clean tap water. 
  • Stir the mortar for 1 minute, by using an electric stirrer, to a smooth and homogeneous mixture. 
  • Wait for a few minutes, stir once again and apply the mortar within 20 minutes with a flat trowel.
  • First apply the mortar in a thin layer and thereafter apply the mortar wet in wet in the required layer thickness of maximum 10 mm.
  • For extra smoothing strickle off the wall with a wet trowel and finish within 60 minutes.
