Implementation

Carqis tiles must be laid in accordance with the rules of the trade and in compliance with DTU 52.2 in force.

TARGET AREAS :

Dry or low-humidity areas (EA) and medium-humidity areas (EB).

PERMISSIBLE SUPPORT

Interior walls :

Nomenclatures of targeted media :

• Non-water-repellent (cardboard faces) and water-repellent plasterboards.
• Plasterboard partitions
• Shaped walls in bare aerated concrete blocks
• Gypsum plaster on masonry walls and partitions
• Cement-based plasters on concrete walls or masonry walls
• Concrete walls or precast concrete panels

New or old substrates must be sanded and then mechanically vacuumed. Substrates must be sound, clean, crack-free, cohesive (superficial scraping with a metal object must not produce dust, grain or scale; perpendicular tensile strength > 0.5 MPa in general), dry, flat (deflection less than 5 mm under the 2-meter straightedge and 1 mm under the 20 cm straightedge), normally porous (between 1 and 5 minutes in the water drop test), clean (notably free of grease, dust and any loose parts), in compliance with current DTU standards.

CONDITIONS OF USE

The choice of bonding product is based on criteria defined according to the standardized characteristics and properties declared by the manufacturers, in keeping with the purpose and use of the room or exposure of the tiled structure.

It is essential to observe the application conditions for the adhesive used. Please refer to the Technical Data Sheet for the adhesive used.

Gluing must not be carried out on frozen substrates.

STORAGE AND SAFETY

Store in original, unopened packaging, away from sunlight and frost, in a temperate room (+15°C minimum).

For further safety information, please consult the Safety Data Sheet.

APPLICATION TEMPERATURE

AMBIENT TEMPERATURE >+ 5°C and <35°C

SUBSTRATE TEMPERATURE >+5°C and <30°C

APPLICATION EQUIPMENT

Tile-cutting tools: dry cutting systems, diamond hole saws, suitable clamps and grinders.

Laying tools: Tile adhesive, notched trowel, adjustment spacer to help level the finished work.

TILE CUTTING

The tile cut-out locations are determined by the preliminary layout. Cut-outs are made using the tools described in the installation equipment paragraph. Particular attention should be paid to circular cuts and tile ends.

ENCOLLAGE

To avoid adhesion problems, the back of CARQIS tiles must be free of dust. C2 thin-bed mortar (1) is applied to the substrate using a trowel (single gluing), then the product is spread using a notched spatula suited to the product. The single-set surface must not exceed the open time of the adhesive (generally between 10 and 20 minutes).

Consumption and gluing method must comply with the following rules (refer to DTU 52.2):

Caution: only a D1 or D2 adhesive (paste) is recommended for glue-down installation:

• on a plasterboard partition (S8 nomenclature) and
• on gypsum-based plaster (nomenclatures S4 and S5).

Adhesive consumption: 3 kg/m² (V6 spatula - 6mm triangular teeth)

Glue-down installation on water-repellent plasterboard partitions (S9 and S10 nomenclatures) is excluded in mortar-glue and adhesive (paste) versions.

On concrete substrates, only C2 thin-bed mortar is recommended.

If 2 different sizes of Carqis tile are used on the same job, use the higher consumption of thin-set mortar and the associated spatula.

In the absence of a specific standard for spatulas, the properties and characteristics announced by the manufacturer of C2 thin-bed mortar should be used as a guide.

TILE INSTALLATION

Ceramic tiles are positioned on the substrate. Any excess adhesive mortar must be removed and the joints hollowed out. Care must be taken when positioning the tiles, as it is difficult to move them once they have been placed on the substrate.

JOINT WIDTH

Zero joint installation is not permitted. Aligned or staggered joints are covered in the present document. Minimum joint width is 2 mm.

JOINTING

With normal-hardening pointing mortar, grouting takes place the next day at average temperatures (15°C to 20°C). For temperatures below 15°C (cold and/or damp weather), this time may be extended.

CLEANING CARQIS TILES AFTER GROUTING

Cleaning removes installation residues. Cleaning should be carried out with water after the joints have been made, before the pointing mortar has fully set.

CARQIS , INSPIRING POSE IDEAS: 2 FOR 1

Carqis innovates in its materials to bring a singularity and a new aesthetic, to bring nature and light into play through the relief and asperities of each tile.

We recommend using two small 2.5 x 15 cm tiles for one large 5 x 15 cm tile.

For 1 m² :

140 tiles 2.5 x 15 cm and 70 tiles 5 x 15 cm

For 1 m² :

140 tiles 2.5 x 15 cm and 70 tiles 5 x 15 cm

Treatment of singular points

WALL/CEILING AND WALL/FLOOR CONNECTION

Under no circumstances should Carqis tiles come into contact with the underside of the ceiling or the rough or finished floor.

SANITARY FIXTURE CONNECTIONS AND WALL PENETRATIONS

It is imperative that the connection between sanitary fixtures and the wall, as well as wall penetrations, are treated before Carqis tiles are laid, to prevent water infiltration (see NF DTU 60.1). Once the covering has been laid, the 5 mm gap between the edge of the fixture and the first row of tiles is filled by the tiler with a sanitary sealant complying with NF EN 15651-3. A profile can be used instead of mastic.

OUTWARD OR INWARD ANGLES

Accessories or profiles as defined in NF DTU 52.2 P1-2 can be used to mechanically protect the edges of cladding elements, to join the cladding element to other materials and to create the corners of tiled surfaces.

These profiles are designed for glue-down installation, the thickness of which must correspond to the thickness of the covering element. They are embedded in the C2 adhesive mortar when the Carqis tiles are laid.

These profiles can be made of ferrous metal (e.g. stainless steel), non-ferrous metal (e.g. aluminum or brass) or plastic in a variety of shapes and colors.

DIVIDING, PERIPHERAL OR EXPANSION JOINTS

This is a completely reserved space, filled during finishing work with a mastic that complies with NF EN ISO 11600 and does not stain ceramic tiles. A metal profile or a PVC profile with a compressible seal can also be used. These are laid at intervals of around 60 m² (corresponding to horizontal joints at a maximum of every 6 m and vertical joints at a maximum of every 10 m).

A 25E "sanitary" sealant is used for damp or collective premises.

In view of the specific nature of materials and worksites, it is essential to assess the risks involved by means of preliminary validation tests adapted to the project. These tests are to be carried out, in agreement with the contractor, by the sealant supplier in accordance with one of the 2 ISO 16938-1 or 16938-2 standards.

POSTS AND CURVED SURFACES

The maximum width of Carqis tiles permitted depends on the radius of curvature R of the substrate, as shown in the table below:

On posts or curved surfaces, Carqis tiles must be laid using double gluing, with a level of adhesive consumption that ensures a full bath with no air voids around the perimeter of the tile.

Acceptance of work

FLATNESS

The tolerances of the finished coating are identical to those of the substrate, plus the tolerance of the tile. Flush is the gap between the edges of 2 adjacent elements, measured perpendicular to the bonding plane. It is due to substrate and manufacturing tolerances. The permissible gap must be less than a third of the width of the joint between the tiles, plus the tolerance of the tile.

FINAL ASPECT

The final appearance of the cladding can be assessed from a distance of around 1.65 m, using non-glancing lighting (angle between cladding and incident natural or artificial light greater than 45°).

JOINT ALIGNMENT

A 2 m rule must not reveal an alignment difference of more than 2 mm, plus the tolerance allowed for Carqis tile dimensions.

COMMISSIONING TIME

The room can be occupied at least the day after grouting. In all cases, please refer to the jointing mortar manufacturers' technical data sheets.

Further information

Handmade, Carqis tiles are unique products.

The care taken in their manufacture does not prevent variations in appearance and color. Carqis tiles have a matt or glossy surface protection.

Despite the high performance and qualifications of this protection, it is not immune to long and repeated exposure, which can damage Carqis tiles.

Avoid prolonged or permanent contact with aggressive chemicals such as acids, bases, vinegar, solvents, bleach, hydroalcoholic gel, etc.

Hydroalcoholic gel sprayed onto the surface of Carqis tiles can cause irreversible damage. Surfaces at risk of exposure must be fully protected.

Carqis tiles are not recommended for use in contact with hot oils (e.g. kitchen splashbacks).
