Instructions for fitting and maintenance of natural stone:

1. The surface to be plated must be non-deformable, dry, fixed and clean. It cannot be mounted on a surface without adhesion. The adhesive must be applied evenly on the surface of the entire board, so that, when it is pressed, the excess adhesive flows from under the board.

2. We recommend using a natural stone adhesive that is elastic and resistant to frost. The place where the tiles were mounted must be protected from rain until the adhesive dries completely.

3. If the tiles are to be fitted properly, it is recommended to wait 24 hours from the floor or wall cladding. Freshly filled joints will be protected from the direct action of sunlight, wind, rain and frost.

4. The stone slabs must be protected from rain at least 24 hours before mounting. The plates must be mounted at temperatures between 5oC and 25oC.

5. PIATRA DESIGN, does not assume responsibility in case of improper fitting and maintenance of stone slabs.

6. It is mandatory to apply a waterproofing solution for natural stone, after installing the tiles.

7. We recommend that the installation be performed by qualified personnel in the field.

Useful information before fitting / assembly:

Natural stone slabs are often packed in very tight crates, being wet at the time of production and packaging and may have traces of dirt due to the various finishing processes they have undergone. Therefore, it is recommended that the natural stone tiles be washed, either with clean water or a professional cleaning solution and allowed to dry completely before installation. As it dries, they lighten in color.

The plates must be dried before installation so that any plates with small defects are placed in areas with low visibility or used for cutting. When installing, always make sure that the natural stone slabs are mixed to ensure consistency in installation and installation, if there are such variations. This means opening all the crates and all the pallets in the material delivered before installation. All boards must be unpacked, and the installer must be aware of your mounting requirements. Minor damage such as cracking / pinching of the edges is often caused by packing and unpacking the boards and this is normal, the boards being used for cutting or in areas with low visibility during the installation process. The installation of the boards starts from the center of the room, and the boards must be dry to avoid any inappropriate cuts or to match the putty layer for the uneven boards. Uncalibrated natural stone slabs should be chosen and marked before installation; thinner tiles will dictate the level of the floor and the first ones should be installed being raised with a suitable adhesive for the large format floor.

The dimensions presented are nominal and there may be small variations in size and thickness for most floor tiles. The support surface on which the floor is mounted should be uniform, level, clean, dry, without traces of dust, grease or dirt. Make sure that you have previously talked to those who install the floor and that they are familiar with the products they are going to install and know your expectations.

1. Before starting the cladding, make sure that the cladding surface is stable, flat, dry and perfectly clean, without impurities. Meeting these conditions guarantees the best possible contact between the adhesive and the substrate. An imperfect contact can lead in time to the detachment of the plate or even to its cracking. 2. At the time of installation, the boards must be washed and dried. The absence of impurities on the board determines a good contact between the adhesive and the board. 3. The adhesive is mixed in a bucket with the help of a mixer, according to the manufacturer’s instructions. 4. The adhesive must be applied evenly both on the support surface and on the surface of the entire board. A trowel is used to apply the adhesive. 5. It is recommended to use a flexible adhesive Technoflex 1054. 6. The cutting of the plates, those that are at the ends of the surface, is done with the help of a diamond disk (related to the material used for assembly) 7. Each model has a sketch that can be found at the stone supplier from which you purchase the products or on the internet. (valid only for certain sets or models, which are sold as such) 8. Pressing the board on the adhesive layer is easy with the palm of your hand. 9. To ensure that the mounted surface is flat, a bubble level is used. 10.The adhesive that comes out from under the plate when pressed is removed with a sponge. 11.To avoid color uniformity, it is recommended to mix the tiles in different packages. The uniformity of the colors means that certain places on the floor will look like spots on relatively large surfaces due to the similar shades that sometimes the tiles in a single package can have. 12.Ideally, before mounting, the tiles can be spread on a flat surface – in a so-called pre-assembly or “cold mounting” – to see what the floor will look like after mounting. 13.Before waterproofing, the tiles are washed and allowed to dry. 14.For joint installation, normal spacers are used for any installation of natural stone, ceramic wall and floor tiles. These spacers can be found at any DIY store. 15.The putty is mixed and made in a clean bowl, according to the instructions received. 16.The putty is made with the help of the putty, and the removal of the excess putty is done with the help of a damp cloth or sponge immediately after its application so as not to dry out. Along with the removal of the putty, the uniformity, the smoothing, of the putty between the plates is achieved, for a pleasant, harmonious aspect. 17.At the end, a special waterproofing for the stone will be applied, for a better protection against liquid absorption.
