    Field of application

    • For use outdoors
    • Protection of facades against driving rain
    • Reduces susceptibility to dirt and green discolouration
    • Mineral building materials, in particular lime-based natural stone

    Properties

    • Solvent-based
    • Improves resistance to frost and de-icing salts
    • Repels water
    • Enables water vapour diffusion
    • Good penetration capacity
    • UV-resistant
    • Alkali-resistant
    • Excellent long-term effect
    • Preparation
      • Substrate requirements

        The substrate must be clean, dust-free and dry.

        Residue (e.g. surfactants, wax) from previous cleaning measures can have adverse effects on the treatment and must therefore be completely removed.

      • Preparations

        Any construction defects such as cracks, cracked joints, defective connections, rising damp and hygroscopic moisture must be remedied in advance.

        Perform any necessary cleaning gently, e.g. by spraying with cold or warm water or by steam-cleaning; use the rotec Soft Whirl Jet 25 l (5235) or Remmers cleaning products (e.g. Traffic Film Remover (0671), Clean FP (0666), Clean AC (0672), Combi WR (0675)) on tough stains.

    • Application
      • By brush / By roller/ Low pressure spraying
      • Application temperature: min. 10 °C max. 25 °C
      • Application requirements

        Temperature of the material, air and substrate: from min. +10 °C to max. +25 °C

      • Apply the primer abundantly by flow coating without pressure (avoid misting), so that a 30 - 50 cm long liquid film flows down the surface.
        Apply on one section at a time, moving from top to bottom, and immediately go over with a large brush.
        Repeat the application several (at least two) times (wet on damp) until no further material is absorbed by the substrate.

        On surfaces where a spraying application is not possible, apply by brush or roller making sure the tools are always well saturated.

    • Application instructions
      • Take appropriate measures to protect adjacent building elements and materials that should not come into contact with the product.

        Protect freshly treated surfaces from driving rain, wind, sunlight and condensation.

        Remove any excess impregnation agent within 1 hour using V 101 thinner.

    • Working tools / cleaning
      • By brush / By roller/ Low pressure spraying
      • Solvent-resistant low-pressure conveying and spraying equipment, liquid pumps, brush, surface brush and lamb's wool roller

      • Tools must be clean and dry.

        After use and before prolonged interruptions of work clean tools with Thinner V 101.

    • Storage / shelf life
      • Shelf-life 24 months
      • Store frost-free and cool / protect for moisture / close containers
      • If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 24 months.

        Use the contents of open containers as quickly as possible.

    • Usage
      • Total application/absorption rate 300 ml - 1500 ml Total / m²
      • Natural stone (fine pored): 0.2-0.5 l/m² Natural stone (coarse pored): 0.4-1.5 l/m²

      • Apply to a large enough trial surface (1-2 m²) to determine the precise amount of impregnation agent required.

    • General information
      • Deviations from applicable regulations must be agreed separately.

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

        Water must not be allowed to penetrate behind the hydrophobized zone.

        The level of absorption is crucial for the impregnation agent to work at its best. This depends on the respective pore volume and moisture content of the building material.

        Testing effectiveness:
        The water absorption of mineral building materials can be determined using the Funcosil Test Plate or the Funcosil Test Tube developed by Professor Karsten (Funcosil Facade Testing Kit, article no. 4954).
        Testing can only be carried out at the earliest 6 weeks after application.

    • 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.

    • Safety / regulations
      • For further information on the safety aspects of transporting, storing and handling the product and on disposal and environmental matters, please see the current Safety Data Sheet.
