Field of application

  • For use on floors/walls indoors and outdoors
  • Subsequent waterproofing of basements from the interior
  • Subsequent plinth waterproofing
  • Waterproofing of reservoirs against inside water pressure
  • Damp proofing for below ground waterproofing measures
  • Building elements in contact with drinking water
  • Salt-loaded substrates
  • WW waterproofing slurry as per DIN 19573


  • Very low emissions (GEV-EMICODE EC 1Plus)
  • Water pressure tight
  • High sulphate resistance and low active alkali content (SR/NA)
  • Very good adhesion to the substrate
  • Enables water vapour diffusion
  • Chemical resistance according to DIN 4030 up to level of attack: XA2
  • Preparation
    • Substrate requirements

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

      Pre-wet highly absorbent substrates.

    • Preparations

      Remove render and/or coatings at least 80 cm above the damaged area.

      In the floor-wall connection remove screed for a width of approx. 20 cm.

      Break off or chamfer corners and edges.

      Coves must be rounded out.

      W1-E: seal pipe penetrations by using the product to form a cove around them.

      Salt inhibitor

      Pre-treat salt-contaminated substrates with Sulfatex LQ and Salt IH.

      Exterior priming:

      Prime mineral substrates with Kiesol (1:1 with water)/Kiesol MB.

      Interior priming:

      Prime mineral substrates with Kiesol (1:1 in water).

      Waterproofing in drinking water areas

      Apply three layers of material to the prepared, pre-wetted substrate without priming.

  • Application
    • Application temperature: min. 5 °C max. 30 °C
    • By brush / Spraying
    • Application requirements

      Temperature of the material, air and substrate: from min. +5 °C to max. +30 °C

    • Apply at least two layers of the material.


      Bonding layer before render application
      Apply another slurry layer of the product and apply render wet-on-wet.

      Alternative: apply a slurry layer of the product, throw on SP Prep, apply render once dry.


  • Application instructions
    • Do not use in direct sunlight.

      The maximum total wet coat thickness must not exceed 5 mm.

      Once it has hardened, mortar must not be made workable again by adding either water or more wet mortar.

      Protect the fresh waterproofing layer from rain, direct sunlight, frost and condensation water.

      Once dry, protect from mechanical damage.

      Please contact Remmers Technical Service (phone +49 5432 83900) before applying with machine processing.

  • Working tools / cleaning
    • By brush / Spraying
    • Mixer, ceiling brush, slurry broom

    • Clean tools with water while the material is still fresh.

  • Storage / shelf life
    • Protect form moisture
    • Shelf-life 12 months
    • If stored in an unopened container and in a dry place, the product will keep for approx. 12 months.
