    Field of application

    • For use indoors and outdoors
    • Wall surfaces and masonry subjected to moisture and damaging salts
    • Old buildings, cellars and facades
    • Removal of salt and reduction of moisture
    • Condensate buffer and protective layer on internal seals


    • High salt storing capacity
    • Porosity: ≥ 50% by volume
    • High sulphate resistance and low active alkali content (SR/NA)
    • Enables water vapour diffusion
    • Capillary-active
    • Single-layer application thickness from 10 to 40 mm
    • Machine workable
    • Preparation
      • Substrate requirements

        Clean, dust-free and capable of supporting a load.

      • Preparations

        Remove render, paint layers and coatings at least 80 cm above the damaged area.

        Chase out friable joints to a depth of at least 2 cm.

        Pre-wet the substrate so that it is slightly moist.

        Substrate: absorbent with low strength

        Apply product as a bonding layer > 50% opaque.

        Substrate: weakly absorbent

        Apply SP Prep (Preparatory Mortar) in nodules as a fully opaque bonding layer.

        Alternative: apply product as a scratch coat (contact layer).

        Substrate: mineral waterproofing grout

        Apply SP Prep (Preparatory Mortar) in nodules to the last grouting layer while wet as a fully opaque bonding layer.
