    Field of application

    • For use indoors and outdoors
    • Interior waterproofing in the Remmers [basic] system
    • Levelling mineral substrates
    • Water-impermeable render and masonry mortar

    Properties

    • Water impermeable
    • Stable
    • High sulphate resistance and low active alkali content (SR/NA)
    • Resistant to water, frost and weathering
    • Pore hydrophobic
    • Machine workable
    • Fibre-reinforced
    • Preparation
      • Substrate requirements

        The substrate must be level, clean, dust-free and stable, and free of oil, grease and release agents.

      • Preparations

        Remove plasters, paints and coatings to at least 80 cm above the damaged area or as indicated by examination and scrape out damaged joints to a depth of approx. 2 cm.

        Primer

        Apply an even layer of Kiesol (1:1 with water).

        Pre-wet highly absorbant substrates with water.

        If necessary, pre-treat salt-contaminated substrates with Salt IH and/or Sulfatex LQ (without Kiesol).

        Bonding layer

        Mix WP Top [basic] to a slurry consistency and apply as a bonding layer to the slightly damp primer.

        Alternatively: apply a bonding layer of WP Sulfatex or SP Prep as a preparatory mortar to the surface once it has been levelled.

        Levelling

        Level out unevenness, depressions > 5 mm and joints with WP Top [basic].

        Apply the plaster to the fresh bonding layer, or after 2-4 days if SP Prep is used as a bonding layer.

    • Application
      • Application temperature: min. 5 °C max. 30 °C
      • Mortar cover / Filling knife / Trowel application / Application by spraying
      • Apply the product using suitable tools or machine equipment in one or two coats with a layer thickness of min. 10 mm to max. 30 mm.

        When applying two coats, roughen the first coat with a render comb and apply the second coat after sufficient drying.

        After application, smooth the surface with a plasterer's float.

        Finish the surface once set.

        Prepare the surface for subsequent coats after sufficient drying using a grated scraper. Apply subsequent coats after 2-7 days.

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

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

        Hairline/shrinkage cracks are safe and are not cause for complaint as they do not impair the properties of the mortar.

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