Capaver Fibreglass AA

Substrates

Interior surfaces made of mineral plasters of mortar groups PI, PII and PIII, gypsum plasters and finished plasters of mortar group PIV, gypsum plasterboard, gypsum boards, concrete surfaces.

High-contrast substrates such as concrete filigree ceilings must be primed with Caparol HaftGrund EG Other substrates must be tested in advance.

Substrate Preparation

The substrate must be solid, dry, load-bearing, clean, level and free from separating substances. Observe VOB, Part C, DIN 18366, Para. 3 and our Technical Information No. 860. The lower temperature limit for application is +5 °C for air and substrate.

Note Q2/Q3 levelling / thin layers of gypsum < 0.5 mm

When using gypsum-based, hydraulically setting levelling compounds in quality level Q2/Q3, a transparent, water-based primer is recommended. Please refer to the Maler&Lackierer Merkblatt Nr. 2 -9/2020 "Haftfestigkeitsstörungen von Beschichtungen auf verspachtelten Gips(karton)platten" des Bundesverbandes Farbe, Gestaltung, Bautenschutz und des Bundesausschusses Farbe und Sachwertschutz.

As an alternative to gypsum-based Q3 levelling, levelling with pasty levelling compounds has proven itself.

Method of Application

No adhesive is applied to the substrate with AquaAktiv glass fabrics! Use a water bath appliance or a suitable pasting appliance with a conversion kit:

• Fill the appliance with clean tap water up to the mark.
• Then insert the roll according to the appliance description and, if available, set the counter to 0.
• The fabric is pulled through the appliance and then folded in a 2/3-1/3 process per lane.
• The water scraper on the device must be in contact and must not be tied back or lifted with adjusting screws!
• The squeegee lips (fleece) must be intact and fully functional.
• The adhesive activates quickly and develops optimum adhesive strength after approx. 1-3 minutes, depending on the structure. Depending on the object conditions (temperature and humidity), this time may be delayed.
• For work in the ceiling area, we recommend an exposure time of at least 2-3 minutes.
• Exceeding the application time can make it difficult to open the sheets and cause the seams to stick together.
• Attention: Wall coverings with a soaking time of > 5 minutes must no longer be processed.
• As long as the adhesive does not come into contact with the substrate, it can be reactivated with water after drying.

Embedding/bonding of glass fabrics and nonwovens:

• Ensure that the backing mark faces the wall when bonding. To avoid differences in structure, never glue upside down or upside down.
• We recommend bonding glass fabric butt-jointed.
• The sheets must be tightly butted in the seam area. However, this must not result in a bulge in the joint area and therefore a poor seam appearance.
• Important! At eye level, it is essential to ensure that the horizontal yarn course (weft yarn) of neighbouring panels is coordinated, otherwise an undesired zip effect will occur.
• Some fabric types have a repeat, which must be paid particular attention to when bonding.
• The bonded strips are then pressed onto the substrate with a wallpapering trowel or a pressure roller, applying sufficient pressure to ensure that the entire surface is bubble-free. Cut off any excess with the wallpapering trowel while fixing the edges.
• When bonding around perpendicular outer corners, ensure that the sheet is guided at least 10 cm around this corner. In order to help very stable glass fabrics/fleeces to nestle against the edge, the fibres on the edge can be lightly sanded with a P320 wet sanding pad (do not sand through!) and pressed firmly.
• For non-perpendicular outer corners, the fabric must be separated at the corner.

Surface Coating System

Intermediate coating:
The intermediate coat forms the basis for a perfect final coat. After the wall covering has dried, the intermediate coat is applied to match the final coat. This must be checked in advance by means of a test coating.

Final coat:
The selection of a suitable top coat depends on the required degree of wear and gloss. Coatings should always be applied wet-on-wet. This also applies to trimming areas.

For detailed information on the above-mentioned coating materials, please refer to the respective technical information for the individual products.

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.
