What is “Sliding Resistance” parameter?
The slipperiness of a floor relates to how safe it is to walk on and, for this reason, is a fundamental feature of the floor itself.
Slipperiness is indicated by th R-value, which refers to a method required by the German DIN 51130 and 51097 standards, which classify products based on their coefficient of friction, as a function of the specific needs of a certain space.
Depending on the level of slipperiness, which could be linked to the use of specific substances in certain work areas, or the presence of water, the standards require the use of flooing materialscapable of creating a significant level of friction between contact surfaces to limit its danger for people. The greater the coefficient of friction, the lower its slipperiness.
The method of measurement specified in DIN 51130 relates to the following classes of slipperiness and states where products can be used:
- R9 – entrances and stairs with outdoor access; restaurants and cafeterias; shops; outpatient clinics; hospitals; schools.
- R10 – communal bathrooms and showers; small kitchens of catering businesses; garages and cellars.
- R11 – environments for the production of foodstuffs; medium kitchens of catering businesses; workplaces where there is a strong presence of water and sludge; laboratories; laundries; hangars.
What is “Surface Appearance” parameter?
The different graphics and the natural shading of each tile are intentional characteristics of this range. When laying tiles, we recommend mixing the various boxes and choosing tiles from different boxes, in order to avoid placing tiles with identical graphics adjacent to each other.

Colours and aesthetic effects
Why are tile colours different from that on the website?
Ceramic products may have a shade of colour which is slightly different from the one visible in the pictures published on the Website.
Being these chromatic differences that are tolerated in the trade of ceramic products and also impossible to predict and/or prevent, it is understood between the parties that the delivery of materials of a tonality which is slightly different from the pictures seen online does not constitute breach on the part of Italiantile.co.uk.
Below, we provide some recommendations for enhancing the features of our products during laying. Before laying, we recommend that you check the colur, size and quality.
The use of materials that are different than you ordered or defective, indicates acceptance of the quality of the materials and rules out claims.
We will non accept claims regarding installed materials with defects that were visible before laying.
Our materials are deliberately producted and selected with slight tonal variations that enhance the effects of the graphics and colours.
On basic technique for installing our products is to carefully alternate different tones by picking tiles in groups of 3 or 4 from at least five different boxes and, especially, the use of series with a degree of tonal variation and chromatic mixing equal to, or greater than, a Value of V2. (What is Value of V2 ? Read SURFACE APPEARANCE)
We recommend that you orient the grain of the tiles to obtain the best aestetic and chromatic effect by harmoniously distributing the different colour nuances that can be seen by checking the results from time to time, looking at a portion of the floor from a suitable distance.
During laying and especially when laying mixed sizes, use minimum joint spacing of 7 mm.
When installing rectified matrials it is indispensable, in any case, to mantain a minimum joint space of 2-3 mm between tiles, using stuccos and sealants whose coloour is coordinated with that of the material.
When installing rectangular rectified materials, it is important to avoid placing the vertex of one tile near the middle of the others in order to compensate for any imperfections of planarity that are, in any case, present in all the large sizes. Since this is cut and rectified material, to avoid this problem, we recommend that you lay the material longitudinally, with a space of 6 to 15 cm between each tile, as shown below (sse drawing).
We strongly recommend that laying be performed by expert personnel who, after checking the corrent planarity of the concrete slab and the quality of the material, will be able to install it in the best way possible.
As for an outside laying, we recommend that you carefully use several techniques:
- Divide the floor into "grids" of smaller surface areas using dilation joints; we recommend placing a joint every 5-10 m2 following the most probable lines for discharging the tensions of thermal dilations.
- Create suitable drainages in the foundation as well as a slope (of at least 1%) and a flat surface in order to avoid pools of water on both the foundation and the surface.
- The concrete slab mus be cast on a waterproofing layer at least 5 cm thick.
- Before laying, make sure there are no areas with largeinfiltrations of humidity, that pipes and channels and well-protected and that the larger construction works have been completed.
- You must use mastics and grouts that are suitable for external use and, thus, waterproof. The joint space between tiles must not be less than 7 mm.
- To avoid water infiltrating the grout, it is a good idea to impregnate it with waterproofing liquid.
We recommend care in the use of grouts because their colourings can stain glazed surfaces. During laying, the surface of the material must not be marked with pencil (graphite) or indelible marker, especially honed products.
Our recomandation is to follow the laying pattern R.L.S. (RAIMONDI LEVELLING SYSTEM).
What is “R.L.S. System”?
Raimondi Levelling System (R.L.S.) is a revolution in the tile setting. In addition to ensuring the proper leveling of tiles, this system helps to speed up the tile setting process. R.L.S. is STRONGLY recommended when installing flexible, large format, heavy or low-thickness tiles (3/5 mm; 1/8" - 3/16").
R.L.S. is made up of three elements: clips (spacers), wedges and pliers. Clips are available in two different versions: for tiles from 3 up to 12 mm thickness (1/8" - 1/2"); for tiles from 12 up to 20 mm thickness (1/2" - 3/4"). The wedge works for both clip sizes and it is re-usable virtually forever. Special traction-adjustable pliers are available in two different versions: for floor or for wall coverings. The use of the pliers is suggested for facilitating and speeding up the insertion of the wedge in the clips. It also optimizes the pressure on the tile.
R.L.S. is the easiest and quickest to remove leveling system: it is enough to kick the spacers to remove the unnecessary part from the installed floor.
No tool required.
HOW TO USE
How to set the support:
- After having spread the adhesive, insert the clip (base/support) underneath the tiles and along the 4 sides.
- According with tiles size, set one or more clips on every side of the tile.
- Set the tile and beat it with a rubber mallet.
How to insert the wedge:
- Insert the wedge in the clip (base) slot paying attention not to pass the breakpoint.
- To facilitate this operation, the use of the special traction-adjustable-pliers is recommended.
How to remove the support:
Once the adhesive is set, the protruding part of the support, has to be removed by separating it from clip/base. This can be done with a rubber mallet or even with feet. Beat parallel to the joint. For further info please watch the exhaustive video below.
Recommendations for grouting
Recommendations for grouting
The final cleaning of any powdery layer of grout from the surface should be carried out when the grout is completely dry (at least 36-48 hours) by cleaning with acid-based detergents by hand (sponge or cloth) or by machine (single brush floor cleaning machine) paying close attention to the recommendations below.
- A buffered acid cleaner, diluted in a 1:5 ratio (1 liter in 5 liters of hot water) in hot water if possible is recommended;
- Quantity: 6 liters of acid cleaner per 100 m2
- Avoid using diluted muriatic acid (due to the release of harmful fumes and the way it "burns" the joints).
- Wet the grout with water only in order to protect it from any corrosion from the diluted acid solution;
- Distribute the diluted acid solution using a normal mop/floor-washer or a coarse rag for residential spaces, or with a single-brush floor washing machine for large surfaces;
- Allow to act for several minutes depending on how dirty the surface is;
- Clean vigorously with a commercial scotch-brite sponge or with a scrubber;
- Wipe up any residue using cloths or with a wet/dry vacuum;
- Rinse abundantly with clean warm water, repeating the operation several times until any marks or residue in the cracks is eliminated.
To maintain the original shine and beauty of your tiles after fixing, the correct cleaning procedures must be followed.
Cleaning after installation
How can I clean tiles after installation?
CLEANING THE TILES IMMEDIATELY AFTER THE INITIAL FIXING AND, AGAIN AFTER THE GROUTING, IS VERY IMPORTANT
At this point thoroughly wash the surface and joints of the tile with clean water several times. This will ensure any residual adhesive or grout will not set on the surface of the tile causing cleaning difficulties later. This is particulary important when fixing tiles with a structured or non slip surface. When grouting tiles with a structured surface it is a advisable to ensure grout does not get spread across the whole surface of the tile.
Whilst throughly washing with clean water will remove residual adhesive and grout from the surface of the tile a proprietary acid based cleaning agent should be applied within 2-3 days of laying to completely clean the surface of the tile. When using secondary cleaning agents it is advisable to "test" the product ona loose tile first to ensure the surface shine and brillance of the tile is not affected.

RECOMMENDED SECONDARY CLEANING FOR EPOXY GROUTED FLOORS
When using grouts it is important to remember they harden much more quickly than conventional water based cement grouts. It is therefore necessary to carry out the cleaning procedures immediately using an alkaline detergent.

How can I clean tiles everyday?
For day to day general cleaning you should use any normal neutral detergent suitable for the cleaning of all ceramic and porcelain tiles. Dilute with warm water and always follow the instructions on the product label.
Difference between Rectified and Natural tiles
What is the difference between rectified and natural tiles?
Rectification is a process that affects the edges of a tile. A mechanical process straightens the tile edges and ensures they are perfectly squared. Because they're very even and uniform, when you're using rectified tiles only the thinnest of grout lines is necessary (3mm or less).
The appeal of a sleek, thin grout line's the main reason people choose these tiles.
A 1.5mm grout line in particular can give an almost seamless look with the right coloured grout and tiles, and it's a fantastic effect when it's well done. Because they're so carefully produced, rectified tiles can be used to create a very clean, even and symmetrical look.
Non-rectified tiles, on the other hand, are tiles with natural, uneven edges that require a wider grout joint.
