Tiefgrund TB

Solvent-based, special primer for exterior and interior use.
  • LV Texte

    Field of Application

    Transparent special primer for exterior and interior use.
    Particularly suitable for gypsum substrates. For priming and solidifying/strengthening existing, superficially sanding render/plaster coatings. Also suitable for surfaces on which existing coats of paint have been removed by washing or mechanical means, as well as for substrates contaminated with residues of waste-paper or glue.
    Do not use the product on ETICS/EWI systems with polystyrene (EPS) boards and on polystyrene containing renders/plasters.
    Do not apply in areas used for storage or preparation of foods.

    Material Properties

    • Strengthening effect/consolidation of substrates.
    • Deeply penetrating to the substrate.
    • Allows diffusion and sorption.
    • Alkali-resistant.
    • Transparent (colourless) when fully dry.

    Material Base / Vehicle

    Acrylic resin in white spirit.

    Packaging/Package Size

    1 l, 5 l, 10 l and 25 l

    Storage

    Keep in a cool, but frost-free place.

    Density

    Approx. 0.8 g/cm3

    Suitable Substrates

    The substrates must be dry, clean, and free from all substances that may prevent good adhesion. 
    In Germany: Follow VOB, part C, DIN 18363, section 3.

    Substrate Preparation

    Please follow our Technical Information No. 650 ("Substrate and their Preparation") for suitability of the product on various substrates and their required pre-treatment.

    Thinning

    Only to be thinned/diluted with white spirit, if necessary.

    Surface Coating System

    Application:
    In normal case: Apply one coat of unthinned product on normally absorbent substrates. 
    On friable, porous render/plaster surfaces: Apply two priming coats, wet-on-wet.
    Thin up to a max. of 20 % with white spirit for priming substrates of low absorbency. 
    The primer must not form a closed, shiny film.

    Consumption

    Approx. 150 - 300 ml/m2 depending on substrate absorbency and thinning ratio/degree of dilution. Determine the exact amount of material required by coating a test area on site.

    Application Conditions

    Lower Temperature Limit for Application and Drying:
    Tiefgrund TB is applicable even in frosty conditions, providing that the substrate is dry and ice free.

    Drying/Drying Time

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

    Tools

    Tiefgrund TB is applied by brush (work in well) or suitable airless equipment. Do not use compressed-air spraying machines.

    Airless Application:
    Spray angle: 60°
    Nozzle size: 0.029"
    Spraying pressure: 50 - 60 bar

    Tool Cleaning

    Clean tools immediately after use with white spirit or brush cleaner.

    Note

    Always provide for a sufficiently long drying time when applied in sensitive areas.
    When using Tiefgrund TB in interiors, a typical solvent odour is released, hence proper ventilation must be provided during application and drying.
    Use non-aromatic, low-odour AmphiSilan-Putzfestiger in sensitive areas
    (see Technical Information No. 670).

    Compatibility with other Paint Products:
    Do not mix Tiefgrund TB with other products.
