Capaver Fibreglass AA

Substrates

Substrate Preparation

Method of Application

For bonding Aqua Active glass fabrics no adhesive (glue) has to be applied to the substrate! Application is effected in a water bath tray/unit or in a suitable pasting unit with conversion kit:

• Fill the unit with tap (potable) water up to the mark.
• Then inlay the roll in conformity with technical manual and reset the counter (if available).
• After that draw the fabric through the unit in 2/3-1/3 method per length and fold it.
• The adhesive (glue) is quickly self-activating and has reached the optimum adhesive power after approx. 1-3 minutes, depending on the texture.
  The time varies depending on conditions on site (temperature and RH).
• For application on ceilings a dwell time of 2 - 3 minutes is advisable.
• Longer dwell times may lead to a difficult opening of lengths and undesirable bonding of marginal areas.
• Note: Do not apply wall coverings with a dwell time of > 5 minutes.
• As long as the adhesive (glue) has no contact to the substrate, it can be (even after drying) repeatedly reactivated with tap water.

Bedding/Bonding of Glass Fabrics and Fleeces

• The reverse side of the roll is normally 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 should be bonded with butt joints.
• 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.
• For bonding glass fabrics and fleeces on vertical external corners, the length must pass around it for minimum 10 cm. Stiff types: 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.
• For non-vertical external corners, the fabrics must be cut at the corner.

Application Conditions

Drying/Drying Time

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

Note

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 fabrics (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 lengths.
