Laying and Grouting

Basically, the criteria for working with VILLI glass tiles are the same as for ceramic tiles. We recommend white thinset mortar for setting VILLI products. It is important to use only adhesives and joint compounds recommended by VILLI (click here). The handling guidelines given by the adhesive manufacturer must be observed. The buttering-floating method must be used for setting large-sized tiles and, in particular, on the out-side of buildings and for facades.

The VILLI glass tiles and mosaics should not be grouted until 24 hours after setting. Please also observe the manufacturer’s instructions for the joint compound. The joint width should be 2 – 3 mm = 1/8 inch. It is best to begin cleaning 20 – 25 minu¬tes after applying the joint compound.

Special instructions for laying VILLI products

KITCHEN AREAS

VILLI tiles should never be laid directly next to an open flame (e.g. on gas stoves). VILLI tiles should be at least 12 inches from an open flame.

WET AREAS / UNDERWATER APPLICATIONS

When installing VILLI products underwater, care must be taken to ensure that they are laid without creating any hollow spaces. This is why mosaics are applied to film instead of netting at the factory. Simply remove the foil once the tile adhesive has set and grout as normal.

METALLIC COLORS

For trouble-free laying of the two colors Vintage Silver and Copper, we recommend using only less aggressive adhesives (for recommended adhesives see back page). Otherwise, changes of colour may occur for which we accept no liability. Should you wish to use any other types of adhesive, we ask you to kindly consult our Technical Department at sales@villiglasusa.com to directly consult the adhesive manufacturer. Metallic mosaics are applied to film/foil on face instead of netting at the factory. Simply remove the foil once the tile adhesive has set and grout as normal.

RELIEF / DECO STRUCTURED RELIEF / FOSSIL

Please note that tiles in the Deco Structured Relief and Fossil series must be wet-cut (Rubi Tools brand or GEMINI brand wet saw performs well in cutting Villiglas).

Guidelines for cleaning when laying

In order to achieve an optimal result in laying VILLI glass tiles and mosaics, it is absolutely essential to observe the following points:

• Do not use any mechanical aids such as metal putty knives or blades, as these can cause damage to the tile surface
• Any traces of adhesive left on the tiles must be removed immediately, using a damp sponge. Dried residual adhesive is far harder to remove.
• After grouting the tiles, extreme care must be taken to frequently change the cleaning water. Excessively dirty water automatically produces a residue of cement, and so possible chemical reactions on the tile surface and any grains of sand which it may contain could scratch the glass surface.
• As soon as the joints are dry, we recommend polishing the entire surface with a dry, lint-free cloth. If you observe the above points, you will achieve a brilliant result.
