Laying

Upon receipt of the material, and in any case before being laid, it is important to carefully check the color, size and choice of material because claims on installed materials cannot be accepted if their defects were visible before use.
For the best possible results with products having a shading coefficient ? V2, lay the tiles by taking them from several different boxes in order to achieve the best possible mix.
For veined products and for natural stone, the slab veins should be arranged to achieve the best esthetic and color effect. Laying can be done both with a bit of cement and with glue, using specific adhesives offering high performance for porcelain stoneware. Glue laying is highly recommended as it offers a greater seal, particularly on large sizes (greater than 45 X 45).
Please remember that when laying the bed must be stable, dry, and ready, neither frozen nor too hot.

In any event, follow the manufacturer’s instructions for the beds and for the specific adhesives used. Cement-based adhesives must be applied at room temperature, in general between +5°C and +30-35°C (between 41°F and 86-95°F).
When laying it is necessary to comply with the timing indicated by the manufacturer of the adhesives being used.
The adhesives most suitable for laying Mirage porcelain stoneware can be identified according to the current European Standard EN12004.
When laying, do not mark the surface of the material with pencils (graphite) or with indelible felt tip pens, especially in the case of polished products. While Mirage products are made using highly durable materials, they can be shaped (for making tops, stairs, and so on) or drilled for installing technical and accessory items using specific diamond wheel cutters and equipment for porcelain stoneware.

Joints and grout

The width of the joint can vary according to tile dimensions and the floor’s intended use. Jointless laying is not recommended, whereas laying with a minimum joint of 2-3 mm (1/8 inch) is advisable (this type of laying provides greater grip of the grout on the sides of the tile, greater absorption of any sub-bed shifting, and tile compensation).
In very large areas, it is essential to position expansion joints at regular intervals, while for small areas it is sufficient to leave a slight gap between the tiled area and the perimeter walls. The skirting board will cover the gap, providing a finished appearance. In any event, follow the advice/suggestions of the designer or site manager.

To use epoxy grouts, additions of resin or the like, it is advisable to carry out a true preparatory cleaning test. For better appearance, we suggest using grouts in a shade matching the color of the tile in order to reduce contrast (e.g., white tile and black grout), especially for lapped and polished products.
After you have grouted tiles in porcelain stoneware, while the grout is still fresh, it is important to immediately and carefully remove excess grout using a sponge and plenty of water.
However, several days after laying when the grout is dried, it is necessary to clean thoroughly using buffered acids (see the post-laying suggestions) in order to dissolve and fully remove residues.

“Post-laying” cleaning

Post-laying cleaning is mandatory after on-site works.
Inadequate or late removal of the grouting used on the joints can leave marks difficult to remove, and create a cement film on the tiles that absorbs all types of dirt, thus giving the impression that it is the tile that has become dirty.
It is indispensable to dissolve and remove these residues completely using buffered acids diluted in water (follow the production instructions), which must then be removed completely and quickly, rinsing the floor with plenty of water to avoid residues or drops on the floor that could damage the tiles.
Allow the product to act on the wet floor without letting it dry, scrubbing with colorless rags. Next, rinse it thoroughly with water to ensure that the floor is free of detergent residues. If necessary, repeat the operation.

We suggest performing a preliminary wash on a sample surface of a few square meters. If the test is successful, continue with the full surface.
When finished, perform a basic or alkaline wash using degreasing detergents. This is because acid can leave grease on the floor, which could contribute to dirt buildup.
More specifically, Mirage recommends particular care with RC02NAT, RC08NAT, WS01 NAT and OX01 NAT when using buffered acids for cleaning: these materials can damage the surface if not removed in a short time and if traces or drops of the water-acid compound are not removed quickly.
