    Suitable Substrates

    Wood, derived timber products, zinc/galvanised substrates, aluminium, copper, unplasticized (rigid) PVC, stable existing coatings. Do not apply on anodised aluminium.
    The substrate must be clean, sound/stable, dry, and free from all substances that may prevent good adhesion.
    Maximum permissible moisture content (WMC) in dimensionally stable wood: 13 %, in limited dimensionally stable wood and wooden parts of unstable shape: 15 %

    Substrate Preparation

    Wooden Parts:
    Sand the surface in fibre direction, clean thoroughly, remove all seeping wood contents, e.g. wood resin/rosin and resin galls (resin/pitch pockets). Cut sharp edges (see BFS Data Sheet No. 18).

    Zinc, Unplasticized (Rigid) PVC:
    Wash with light ammonia solution using a sanding pad as per BFS Data Sheet No. 5 and No. 22.

    Aluminium, Copper:
    Clean with destined detergents, e.g. Gescha Multi-Star, then sand with a plastic abrasive fleece (see BFS Data Sheet No. 6).

    Existing Paint Coatings:
    Sand the surface of existing coats of paint and/or treat slightly with alkali. Remove unstable existing coatings.

    Method of Application

    Capacryl Haftprimer is ready for use and can be applied by brush, roller or spraying equipment. 
    Stir well before use and dilute to a max. of 5 % with tap (potable) water, if necessary.

    Two intermediate coats are required on dimensionally stable wooden parts, according to BFS Data Sheet No. 18.
    1)Always apply Capacryl Holz-IsoGrund on wood with water-soluble, discolouring substances of content, 2x for knots.
    2)Pretreat defects in existing paint coatings according to substrate requirements.
    3)Apply two finishing coats, if necessary (e.g. when yellowish or reddish colour shades with low opacity/covering power are used).
    Note: Adhesion must be tested in advance for powder coatings, coil coatings and other problematical substrates by a trial coating.

    Consumption

    Approx. 100 - 130 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.

    Application Conditions

    Lower Temperature Limit for Application and Drying:
    +8 °C for product, substrate and ambient air.
    Relative humidity must not exceed 70 %.
