    Field of application

    • For use outdoors
    • Protection of facades against driving rain
    • Reduces susceptibility to dirt and green discolouration
    • Porous, mineral building materials in outdoor areas
    • Protection against driving rain when retrofitting cavity insulation and interior insulation

    Properties

    • Highly water-repellent
    • Enables water vapour diffusion
    • Improves resistance to frost and de-icing salts
    • Outstanding penetration
    • UV-resistant
    • Alkali-resistant
    • Excellent long-term effect
    • Can be applied sparingly, with absolute precision and with no losses
    • Quickly becomes rain-proof, approx. 60 minutes after application
    • Preparation
      • Substrate requirements

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

      • 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 / Airless/airmix 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 impregnation agent with a suitable tool, working crosswise, or by airless spraying.

    • 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 / Airless/airmix spraying
      • Long-pile lamb's wool roller, brush. Airless nozzle: 40° spraying angle, hole 0.021 inches, max. 60 bar spraying pressure

      • Tools must be clean and dry.

        Clean tools with water after use and before any lengthy interruptions to work.

    • Storage / shelf life
      • Shelf-life 12 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 12 months.

        Use the contents of open containers as quickly as possible.

    • Usage
      • Total application/absorption rate 150 ml - 200 ml Total / m²
      • Depending on the porosity, in one coat: approx. 0.15 - 0.20 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.

        Carry out a quantitative analysis of aggressive salts if there are any salts present that could damage building materials.

        High concentrations of harmful salts can cause major structural damage that impregnation cannot prevent.

        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.

        Substrates with very low absorbency and highly textured surfaces should be treated with a liquid impregnation agent.

        A test of effectiveness needs to be carried out on carbonaceous natural stone.

        Always set up a trial area/trial areas first.

    • 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
