    Explanation:

    No alteration
    = No visible changes. The test area is indistinguishable to the ambient surface.

    Small alteration
    = The test area is visibly different to the ambient area, but only in case of light reflection, e.g. noticeable due to discolouration or changes in colour or gloss level. The surface texture remains unchanged (no swelling, crack formation or blistering).

    Modest alteration
    = The test area is differing to the ambient surface, e.g. due to colour changes, discolouration or variation in gloss level. The surface texture remains unchanged (no swelling, crack formation or blistering).

    Suitable Substrates

    Prime surfaces of building materials, such as dimensionally stable wooden parts, derived timber products, steel, galvanised steel, zinc sheets, aluminium, copper, unplasticized (rigid) PVC, stable existing coatings in- and outdoors.

    Do not coat the following surfaces/substrates with Capalac Aqua 2K- PU-Lack:
    Stainless steel, anodic/anodized coatings, bronze, brass, surfaces with permanent moisture stress such as showers and swimming pools. 
    Roofing, flooring, balcony floors, travelled floors.
    Limited stable and unstable wood construction elements.
    Derived timber material boards and plywood boards (e.g. boards with layers of wood veneer) outdoors.  

    Substrate Preparation

    Sand and clean the primed surfaces.

    Preparation of Material

    Add the hardener (catalyst) to the base, directly before use. Stir intensely by hand or use low-speed paddle mixer (agitator; max. 400 rpm). Then pour into another clean mixing vessel and stir again very thoroughly.
    The material temperature of both components should be 15 °C to 20 °C.

    Mixing Ratio

    Base : hardener = 9 : 1 parts by volume or 
    Base : hardener = 100 g : 9.8 g parts by weight

    Specifications may vary, depending on the device/product manufacturer.

    Application:

    Capalac Aqua 2k PU-Lack can be applied by enamel brush, enamel roller or with spraying equipment. Particularly for spray painting the local prescriptions for environment protection and industrial safety regulations for using isocyanate containing products must be followed.
    Use special brushes, suitable for "aqua-type" (waterborne) enamels , such as Orel-Mix, Friess Blueline or Wistoba 1528 Krex . On larger surfaces apply the product with a short pile (textured) polyamide (nylon) roller and directly roll over with a fine-porous foamed plastic roller or use aqua enamel type brush for reworking.

    Thinning

    Capalac Aqua 2K PU-Lack is ready-to-use for application with enamel brush and roller. Dilution is not necessary. 
    Dilution with tap (potable) water is possible for spray application, depending on device and spraying method.

    1) Apply two intermediate coats on dimensionally stable wood component parts, in compliance with BFS Data Sheet No. 18.
    2) Always apply Capacryl Holz-IsoGrund on wood with water-soluble, discolouring substances of content that leave marks (2x for knots).
    3) Intermediate coat, tinted to match the finishing coat in shade. For reddish, yellowish or orange shades with low opacity (hiding/covering power) a differing colour is mixed via ColorExpress, providing for a better hiding power of the finishing coat. This colour is somewhat differing to provide for a better hiding power of the top coat.
    4) An additional coat may be necessary when colours of low opacity are used (e.g. shades of yellow/red/orange).
    5) Note: Adhesion must be tested in advance for powder coatings, coil coatings and other critical substrates by trial coatings on site.

    Consumption

    Approx. 100 - 120 ml/m2 per coat.
    Consumption is only a guide value and may vary, depending on substrate requirements. Determine the exact amount of material required by coating a test area on site.

    Workability

    (Pot Life)
    2 hours at 20 °C. Higher temperatures shorten, lower temperatures extend the pot life.
    Note! The end of pot life is not visible. Exceeding of pot life as well as overdosage or underfeeding of hardener leads dramatically to a loss of product properties.

    Application Conditions

    Low Temperature Limit During Application & Drying: 
    8 °C for product, ambient air and substrate.

    Drying/Drying Time

    At 20 °C and 65 % relative humidity (RH).dust dryrecoatablecured
    after hours1 - 210 - 1248
    Lower temperatures and higher humidity extend the drying time.

    Tool Cleaning

    Clean tool after use with water and wetting agent, e.g. Gescha Multi-Star. It is recommended
    the wearing of nitrile gloves.
