    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


    • 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.

      • 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 slope corners and edges.

        Coves must be rounded out.

        Seal passing-through pipes by using the product to form a cove around them.


        Salt inhibitor

        For renovation work, it is recommended to apply two layers of a salt inhibitor (Art. 0663) in order to bind any sulphates present.


        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 without priming on the previously prepared substrate.


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

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

      • Apply two layers of the material, wet-on-wet.

        Waiting time between the second and third coat: min. 24 hours.

        Then apply a third grouting layer of the material and throw on Repellent Render or, alternatively, SP Prep (Preparatory Mortar), wet-on-wet.


    • 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.
