    Field of Application

    Capaver glass fabrics provide for highly attractive, high-grade and individual wall surfaces, due to variations in texture, type, colour shade, gloss level and application technique of topcoats.
    In accordance with the expected degree of stress or desired visual appearance, all glass fabrics may easily be coated with suitable paints and efficient renovations are possible, due to individual needs.

    Material Properties

    • Homogenous visual appearance of the texture.
    • High strength in wet conditions.
    • Rot proof, dimensionally stable. 
    • Covers small surface cracks (crack bridging).

    Material Base / Vehicle

    Capaver Glass Fabrics K are made of purely mineral glass yarns.

    Capaver Glass Fabrics K are composed of glass fibres with a diameter > 5 µm, particles of that size cannot enter the respiratory tract. Although the fibres are highly bonded in the fabric, a limited amount of glass particles may be released when cutting the fibres/glass fabrics. This may cause itching of skin to people with a sensitive skin and suitable protection should be used during application, but will fade away after bonding. Capaver Glass Fabrics K do not release any glass fibres after being coated.
    Dynamic cracks in the substrate cannot be removed/durably bridged with Capaver Glass Fabrics K.

    (–) inapplicable / (○) of limited suitability / (+) unsuitable


    Interior surfaces: Mineral plasters in mortar groups/classes PI (lime plaster), PII (lime-cement mortars), PIII (cement mortars), PIV (gypsum mortar and ready-mixed gypsum plaster), plasterboards/gypsum cardboards (drywalls), gypsum wallboards, concrete.

    Substrate Preparation

    The substrate must always be solid, dry, sound/stable, clean, even and free from all substances that may prevent good adhesion. Follow Technical Information No. 650.
    In Germany: Follow VOB, part C, DIN 18366, section 3.
    Lower temperature limit for application and drying: +5 °C (product, substrate and ambient air).

    Method of Application

    Roller Application of Adhesive (Glue):

    • Apply Capacoll GK evenly with a roller (18 mm piles), but only for 1-2 fabric lengths, depending on the temperature on site.
    • Note: Agglomeration of adhesive material must be avoided to achieve a uniformly textured surface.

    Spray Application of Adhesive (Glue):

    • A minimum of 3 workmen on the job is required.
    • Capacoll VK can directly be applied to the wall with airless equipment.
    • Capacoll GK should be diluted with 20 % of tap (potable) water, depending on the conditions on site.
    • For spray application it is suggested to observe the recommended material consumption and to spread the adhesive evenly, avoiding a surplus of applied product.

    Advice: Detailed information concerning the spray application of CapaColl are given within our German manual "#843604 Handbuch der Spritztechnologie".

    Bedding/Bonding of Glass Fabrics:

    • The reverse side of the roll is marked and has to be bonded to the wall. To avoid differences of appearance in texture/pattern, always place the fabrics running in one direction and not laterally reversed.
    • Capaver Glass Fabrics are to be bonded with butt joints.
    • Note: Provide for narrow butt joints, but the forming of bulges must be avoided to achieve a proper visual appearance.
    • Important: The horizontal run of yarns (weft yarns) within joining lengths should match at eye level, avoiding an unintentional "zipper" effect.
    • Some fabric types have a pattern repeat, which must be considered for bonding.
    • Press the bonded lengths void-free with sufficient pressure to the full surface using wallpaper scraper or pressure roller.  Fix the edges and cut of the excess length with a wallpaper scraper.
    • Hint: For bonding Capaver glass fabrics on vertical external corners, the length must pass around it for minimum 10 cm. For non-vertical corners, the fabrics must be cut at the corner.
    • For bonding stiff glass fibres and vleeces on external corners, sand the fibres on edges with a wet sanding pad type P320 (but only a little and very carefully; do not sand through the material) to induce a better pliability and press on.

    Surface Coating System

    Intermediate Coat:
    The intermediate coat forms the basis to achieve a perfect finishing coat. The intermediate coat can only be applied when adhesive and fabric are completely dry, and should be tinted to match the finishing coat in shade. Apply one filling intermediate coat of Capaver Gewebegrundierung before applying coats of thin film paint, e.g. latex paints.

    Finishing Coats:
    Selection of suitable products for finishing coats is depending on the degree of expected loads and desired gloss level. Coatings must be applied wet-on-wet (also effective for trimming areas).

    Drying/Drying Time

    Allow bonded glass fabrics to dry thoroughly before any further coating.


    On principle the marked interior side of a roll has to be bonded to the wall. The outer side of the roll is the visible face. To avoid differences of appearance in texture/pattern, always place the fabrics running in one direction and not laterally inverted.

    Capaver wall coverings are thoroughly inspected by the manufacturer. In exceptional cases isolated production related weaving faults may occur. These faults are marked at the trimmed edges and correspondingly compensated. They do not entitle to any objection. While cutting and bonding the fabric lengths, ascertain whether there are no weaving faults. In case of complaint the label with the batch and product numbers (see original carton) must be kept ready. Claims based on material faults cannot be objected after the application of more than 10 fabric lengths.
