    Field of application

    • For use indoors and outdoors
    • Subsequent waterproofing of basements from the interior
    • Subsequent plinth waterproofing
    • Damp proofing for below ground waterproofing measures
    • Waterproofing of reservoirs against inside water pressure
    • Quick, waterproof repair of defective areas

    Properties

    • Single-layer coating thickness up to 50 mm
    • High sulphate resistance and low active alkali content (SR/NA)
    • Fast curing
    • Water pressure tight
    • Grouting to filling consistency can be adjusted by adding water
    • 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.

        Remove projecting seams and mortar remains.

        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.

         

        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.

    • Application
      • Mortar cover / Filling knife / Trowel application / Jointing iron
      • 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

      • 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.

        Damp proofing

        Apply one layer on the previously prepared surface.

         

        Filler waterproofing

        Apply at least two layers of the product as a filler.

        The following layer is applied as soon as the preceeding one can no longer be damaged.

         

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

        Long waiting times for subsequent layers should be avoided.

        Protect wet mortar surfaces against frost, rain and drying out too quickly for at least 4 days.

        Eliminate all sources of moisture before commencing repairs.

        As water loads can vary, we recommend application in 3 layers.

    • Working tools / cleaning
      • Mortar cover / Filling knife / Trowel application / Jointing iron
      • Mixer, soft wide brush, ceiling brush, trowel, spreader or jointing iron

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

    • Storage / shelf life
      • Protect form moisture
      • Shelf-life 6 months
      • Dry, in unopened containers, 6 months.
