    Field of application

    • For use indoors
    • Reinforcement and finishing render in the iQ-Therm system
    • Improving the energy performance of exterior walls

    Properties

    • Temperature-regulating
    • Water vapour permeable
    • Highly capillary active
    • High moisture storage capacity
    • Single-layer application thickness up to 10 mm
    • Two-layer application thickness up to 15 mm
    • Preparation
      • Substrate requirements

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

      • Preparations

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

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

      • Contact layer

        Using a suitable tool, apply the product as a contact layer.

         

        Reinforcing layer

        Apply render in a layer thickness of 5-6 mm using a toothed trowel.

        Embed reinforcement fabric in the upper third of the render, with fabric widths overlapping by at least 10 cm.

         

        Surface decoration

        Apply the second layer while the first is still wet.

        Smooth the surface using a suitable tool.

        Finish the surface once set.

        Prepare the surface for subsequent layers with a grated scraper after sufficient setting.

         

    • 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.

        Apply additional diagonal reinforcement to the edges of building openings.

    • Working tools / cleaning
      • Mortar cover / Filling knife / Trowel application
      • Mixer, smoothing trowel, toothed spreader, levelling rule (aluminium), render comb, broom, trowel, felt float

      • 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.

    • Usage
      • Approx. 6.0 kg / cm thick layer / m²
      • Approx. 6 kg/m²/cm layer thickness

    • General information
      • Do not work on substrates where moisture is penetrating from the rear.

        The colour that is obtained after drying and hardening depends on the ambient conditions and the processing method. For instance, a freshly smoothed surface will be lighter than one that is smoothed later or roughened. Different grain sizes of the same product may lead to slight differences in colour. Substrates soaked from the back may cause discolouration.

        May contain traces of pyrite (iron sulphide).

        Do not use on gypsum-based substrates.

        The mixing water must be of drinking water quality.

        Low chromate content in accordance with Directive 2003/53/EC.

        Deviations from applicable regulations must be agreed separately.

        The relevant test certificates must be observed when planning and carrying out work.

    • Disposal instructions
      • Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
