  • LV Texte

    Field of Application

    Aqueous microbiocide for the priming of algae and mold infested or endangered, porous and absorbent substrates on interior and exterior substrates before subsequent coatings.

    Product type: Wall protection agent PT 10 (according to biocide regulation 528/2012 / EU).

    Material Properties

    • Disinfects algae and fungus-infested surfaces
    • High penetration through cation technology
    • Reduces the absorbency of the substrate
    • Diffusible and sorbent

    Material Base / Vehicle

    Cationic polymer dispersion

    Packaging/Package Size

    10 l




    Store in a cool but frost-free place.


    Approx. 1.0 g/cm3

    Supplementary Product



    In the case of very strong algae and fungus infestation on the surfaces to be coated, we recommend an additional thorough cleaning with Capatox using a brush after high-pressure cleaning. This also disinfects spores in deep-lying areas. After drying, the absorbency can be regulated with FungiGrund.

    Suitability according to Technical Information No. 606 Definition of Application Areas

    Interior 1Interior 2Interior 3Exterior 1Exterior 2
    (–) not suitable / (○) conditionally suitable / (+) suitable

    Suitable Substrates

    The substrates must be free of dirt, separating substances and dry. Please note our Technical Information No. 650 "Substrates and their pretreatment” with regard to their suitability for different substrates and their necessary pre-treatment.

    Method of Application

    With a paint brush or brush, the full, strengthening effect is achieved by applying it generously. Application with the roller is also possible.


    Always apply the product undiluted.

    Surface Coating System

    Apply undiluted once on normally absorbent substrates. Apply once undiluted, but generously, to highly absorbent surfaces. Apply wet-on-wet, with a brush, flat brush or paint brush until the substrate is completely saturated. The primer must not form a closed, glossy film.


    Approx. 150–250 ml/m2, depending on the absorbency and type of substrate. Determine the exact consumption by means of a test coating.

    Application Conditions

    Material, air and substrate temperature: Min. +5°C to max. +30°C.

    Drying/Drying Time

    At +20°C and 65% relative humidity recoatable after approx. 12 hours. 
    Lower temperatures extend the drying time.


    Paint brush or brush.

    Tool Cleaning

    Clean tools immediately after use with soap and water.


    FungiGrund is not suitable for horizontal surfaces exposed to water.

    Compatibility with other materials:
    FungiGrund must not be mixed with other materials.
