    Suitable Substrates

    Iron, steel, zinc (galvanised steel), aluminium, copper, stable existing paint coatings.
    The substrate must be clean, sound/stable, dry and free from all substances that may prevent good adhesion. 
    Do not use for the coating of roofings and anodized aluminium!
    Existing coatings may require a trial coating and check for proper adhesion. This applies in particular for powder and coil coatings.

    Substrate Preparation

    Iron, Steel:
    Derust to industry standard SA 2½ (blasting) according to DIN EN ISO 12944-4.
    A thorough removal of rust to the degree of purity ST 3 by mechanical means or by hand may be sufficient, if corrosive loads are low (e.g. indoors without any formation of water condensation and other aggressive influences).

    Zinc, Galvanized Steel:
    Roughen and clean with non-woven web and Multistar, 1 : 5 diluted with tap (potable) water, otherwise use light ammonia solution or prepare via sweeping technique as per German BFS-Merkblatt (Data Sheet) No. 5.

    Aluminium: 

    Roughen/clean with non-woven web and Multistar, 1 : 5 diluted with tap (potable) water. Germany: Follow BFS Data Sheet No. 6.

    Copper: 
    Roughen/clean with non-woven web and Multistar, 1 : 5 diluted with tap (potable) water.

    Existing Paint Coatings:

    Roughen the surface and/or treat with alkali. Carefully remove all unstable coatings.

    Prefer spray application for corrosion protection conforming to standards. Check the thickness of the wet film with suitable gauge to achieve/ensure the necessary dry film thickness. 
    On large, seamless areas a "clouding" effect may occur with spray coating and is sometimes unavoidable, due to sectioning surfaces in several operation segments.

    Note: Adhesion must be tested in advance for powder coatings, coil coatings and other critical/problematic substrates by trial coatings on site.

    Application:
    Capalac Aqua Metallschutz can be applied by enamel brush, roller or spraying equipment. Stir thoroughly before use. Spray application should be used to achieve the necessary wet and dry film thickness and protection against corrosion conforming to standards (see following tables/corrosivity categories.

    Adhesive Tapes to Limit the Coating: 
    Remove all adhesive tapes before the coating (film surface) is dry. Otherwise the coating will be raised in border areas, due to the high dry film thickness. Use waterproof adhesive tapes.
