What is a ceramic tile?
“Ceramic” comes from the Greek term Keramos, meaning "a potter" or "pottery”.
Since the infancy of ceramics, up to this very day, the process is still very much the same; for the creation of all ceramic materials, one needs to bake a mixture of clays at a very high temperature.
A ceramic tile, therefore, is the resulting product, after a mixture of clays have been treated appropriately, pressed, fired at a high temperature and cut to size. A ceramic tile consists of two parts: the body, which is called the “bisque” and the surface, which is called the “glaze”.
Which sizes are available for ceramic tiles?
150x600mm, 445x445mm, 300x600mm, 300x300mm
What are glaze porcelain tiles?
Porcelain tiles are made from a blend of fine-grain clays and other minerals to produce a very dense body, which makes them highly resistant to moisture, staining and wear. These tiles are more dense than ceramic tiles and have water absorption of >0.5% and <3%. Because porcelain tiles have low water absorption, they are usually frost resistant.
Porcelain tiles with special glazes fired at high temperature make the glazed surfaces very hard, and therefore, suitable for heavy traffic areas. Porcelain tiles are resistant to stains, scratches, frost and abrupt thermal changes.
Because of these features, porcelain tiles are able to withstand years of heavy foot traffic in both interior and various exterior locations. They are also able to maintain their color and beauty for a very long time.
What are vitrified tiles?
Vitrified tiles are non-glazed tiles. Their hardness and polish is achieved by virtue of the pressing together of very hard materials. Vitrified tiles are extremely strong and durable and processed in such a way that they allow for very little water absorption. Vitrified tiles have a water absorption of < 0.1%.
Vitrified tiles allow for a “full body” tile, which means that the design is not merely on the surface of the tile, but runs throughout the entire tile. The advantage of this is that the tiles become incredibly strong.
Which sizes are available for vitrified tiles?
600 x 600 mm, 800 x 800 mm and 1000 x 1000mm
What are Marble Sandwich Slabs?
This is also an entirely new concept. Marble sandwich slabs have a porcelain (8mm) base and a surface of polished natural marble (4mm).
The advantages of marble slabs are that they are cheaper than natural marble, easy to install whilst they also retain the beauty of natural marble. Another advantage of these slabs is that they don’t need polishing once purchase (as opposed to natural marble) because they have already been polished. If, however, after 6-8 years, the surface requires re-polishing, it ought to be polished in the same way as natural marble.
What is natural and engineered marble?
Nitco distributes two types of marble:
1. Natural marble
2. Engineered marble
Natural Marble
Natural Marble, as the name suggests, is procured directly from marble mines and is extracted in block-form. It is then cut into slabs and strengthened by a layer of fiber, which is smeared onto one side. This fiber then dries, giving the marble slab the necessary strength for its transportation. Since natural marble possesses gaps, these are filled in with a resin. The entire marble surface is then polished, using special polishing and waxing machinery.
Natural Marble comes from various parts of the world and Nitco is one of the largest Indian importers. Below are some of the more popular natural marbles:
White :
Australian White, Brazillian White, Carrara, Statuario, Statuario Venatino and White Thassos.
Beige:
Antique Beige, Bottochino, Crema, Crema Marfil, Crema Novita, Danish Cream, Dyna, Florentino, Beige, Marfil Supreme, Moon Cream, Perlato Savoy, Parlato Sicillia, Regal Beige, Royal Beige, Royal Pearl, Serpegantte, Silvia and Sunny Valencia.
Various colors:
Black Marquina, Crema Flurry, Fire red, Grey Chegin, Grey William, Olive Green, Red Alicante and Brown Emperador.
Travertino:
Beige Travertino, Red Travertino and Yellow Travertino.
Onyx
Honey Onyx and Tiger Onyx.
Because natural marble differs from slab to slab, it is impossible to state the precise properties of natural marble. However, below are some typical properties of three types of marble:

What are the advantages and disadvantages of engineered marble?
Please see the section on engineered marble.
Engineered marble
Engineered marble is a hardened mix of natural marble chips and various other materials. 92-95% of the material is in fact natural marble. Together with various resins, natural marble chips are processed and pressed into block form. These blocks are then left to dry overnight and then finally cut into slabs, ready to be distributed.
The thickness of engineered marble slabs can vary between 18mm to 20 mm, depending on the requirement.
The Slab size is 300x 120 cm can be cut into all different sizes.
What are the advantages and disadvantages of natural marble?
Having different properties, engineered and natural marbles also have their individual advantages. You will need to be aware of these, in order for us to satisfy your wishes.
Advantages of engineered marble and disadvantages of natural marble
Engineered marble is more environmentally friendly because it uses the ‘marble chips’, which are the by-product of marble mining. Using these marble chips in stead of discarding them, means that less marble has to be sold and therefore mined.
Because of its hardness (3-4 MOHs), engineered marble is suitable for high traffic floors such as internal facades, counters, stairs, steps, bathrooms, borders, furniture and corridors. It may also be used at such places because it has a low water absorption, and is resistant to cracking and warpage.
Natural marble often cracks.
Natural marble is harder to select. Because each and every marble slab differs in design, each slab must be personally chosen by the customer.
We do not, however, recommend engineered marble for use outside, because natural sunlight can weaken the color of the slabs.
Engineered marble does not need to be polished as often as natural marble.
As opposed to natural marble, engineered marble is free of cavities and there is no risk of cracking veins.
Advantages of natural marble
Some would say that natural marble is more aesthetically pleasing than engineered marble, but of course, this is always depends on the customer’s view.

What is Engineered Quartz?
Engineered Quartz is a very hard material (5-6 MOHs), with minimal water absorption, resistance to acids, oil and other liquids. It also requires little maintenance costs and is very easy to clean.
Because of its above listed qualities, it may be used in at reception desks, kitchen worktops, for bathroom and washroom vanities, floors, walls and steps. It is very aesthetically pleasing and can be seen, for instance, at many retail stores, hotels, leisure centers, airports and museums.
Engineered Quarts comes in a standard slab size of 4ftx8ft and may be cut into various lengths.
Crystal White Marble
Crystal White Marble has a shiny and highly polished surface. It has a porcelain base and a surface of polished crystal. It is a very strong material and has low water absorption. It is very stain/frost resistant and its color does not fade when left in natural sunlight. It is therefore very suitable for use outdoors.
What is Mosaico?
Mosaico is the art of creating images with an assemblage of small pieces of colored glass, stone, or other materials. Mosaics by Nitco normally use three materials; marble, stone and Ceramic/Vitrified tile pieces.
Our mosaico manufacturing line, based at Kanjur Marg in Mumbai works hard every day to create the finest mosaic designs conceivable. What is, however, very special about our mosaico facility, is that our customers are able to chose their own designs, no matter how large or complicated these may be.
Can I really choose my own Mosaico designs?
Yes, you can! As a customer, you can select both the design and color of the image. This is a part of our ‘Custom Made’ or ‘Non Standard’ series. Before making the Mosaico design, we show you on a computer screen exactly what it will look like. Please see the Mosaico section for inspirational designs. If you find these elegant and beautiful, please visit your local Nitco Showroom for further information.
How does the Mosoaico process work?
Depending on the design and color combination as well as the size of the mosaic, the components (ceramic tile pieces/vitrified tile pieces/stone or marble) are cut into the required sizes and arranged accordingly.
What are Inlays?
Most inlays are made with the use of a ‘Water-jet Cutting Machine’. The beautiful designs are very beautiful and in fact also very affordable. If you would like to see more, please see the inlay designs on this web site or at any one of our Le Studio showrooms throughout the country.
Vitrified Inlays are available in the following sizes: 600x600mm, 605x605mm, 800x800mm, 1000x1000mm.
What is Metal Craft?
With the use of a Water Jet Cutting Machine, we are able to transform marble slabs into the most unfathomable designs, beautiful beyond imagination. This machine also enables us to cut any design out of metal, a procedure also known as ‘Metal Craft’.
What things should I consider when buying a tile?
First of all, you must be sure that you are investing in a brand that you can rely on. When you invest in Nitco, you can only win. We check the quality of each and every one of our products independently, to ensure that only the best products are given the Nitco brand label, which is synonymous to great quality and design.
More specifically, however, there are a number of technical factors (please see below) which one should be aware of when buying tiles. For all the tile properties mentioned below, Nitco always maintains the highest standards in the testing of the tiles; from the laboratory all the way through the manufacturing process. Throughout the manufacturing process, the following elements are in constant check; deviation in length, deviation in thickness, straightness of sides, rectangularity, surface flatness, modules of rapture etc.
Water absorption
Water absorption refers to the quantity of water a tile absorbs when it gets in contact with water. A precise percentage is calculated by the loss of weight when a wet tile is dried in the laboratory oven. As a customer you will be interested about this percentage, because it will determine how stain resistant your tiles are, and whether they are frost resistant (i.e. if a tile absorbs water, which subsequently freezes, the tile will expand and crack).
Generally, ceramic tiles with a water absorption between 3 to 6% are used as floor tiles and ceramic tiles with a water absorption between 10 to 15% are used as wall tiles. This is because the lower the water absorption, the less likely it is that there will be stains after contact with liquids. The lower the water absorption, the longer your tiles will look new.
Floor tiles can also be used as wall tiles depending on their aesthetic features. We would, however, very much recommend not using wall tiles as floor tiles because of their low strength and high water absorption. Although this may be cheaper at first, such tiles will not be aesthetically pleasing for a long time.
Here is a list of tiles and their corresponding levels of water absorption:
Vitrified tiles - <0.1 %
Glaze Porcelain tiles - >0.5 <3%
Ceramic floor tiles – 3 to 6%
Ceramic wall tiles – 10 to 20%.
Slippery surface -
Slippery surfaces can be a hazard, especially when there is a possibility of water spilling onto the surface (e.g. in the bathroom). We therefore offer glossy (slippery) and non-slippery tiles. Our very successful Naturoc series, for instance, is an example of a non-slippery tile.
Surface hardness/Scratch resistance
An aspect of tiles is their surface hardness and resistance to scratches. The level of the hardness is measured in MOHs. The Mohs scale ranges from 1 to 10, level 10 being the hardest. As you will see in the technical specifications for all our tiles, Nitco maintains higher levels of scratch resistance than is required by the EN (the official body regulating such matters) standards.
For Glazed tiles the PEI method used to measure abrasion resistance, is rated by the following scale:
• Group I: Tiles that are suitable for residential rooms with light foot traffic. Generally wall tile products fall into this group. Only rarely, are wall tiles able to be used as floor tiles.
• Group II: Tiles that can be used in residential medium-level traffic areas. Only in some cases may they be used in high traffic areas such as in kitchens, bath rooms bed rooms etc.
• Group III: Tiles that are recommended for use in all residential areas.
• Group IV: Tiles that are suited for all residential areas and also light to medium commercial areas (which usually have higher traffic).
• Group V: These tiles can be installed in almost any commercial and residential setting
Frost resistance This is the ability of a tile to withstand very low temperatures. The frost-resistance of tiles is dependent on it’s water absorption levels. This is how it works; if a tile absorbs water, which subsequently freezes, the tile will expand and crack.
Do tiles break, after being laid?
Tiles only break once they are laid, if there is an air bubble between the base of the tile and the setting material.
Can tiles be laid on tiles?
Yes, it is possible for tiles to be laid upon tiles, but care should be taken that the floor is level. Laying tiles upon other tiles is of course cheaper and less time consuming than completely renovating the floor.
Which material is used for the laying of tiles?
Cement. For laying tiles upon tiles, a chemical adhesive is used.
Does Nitco do the tile laying?
Unfortunately not, but we can, however, recommend a contractor, who bears full responsibility for the work he does. Please contact one of our showrooms in your area and they will be happy to help you.
What are the different measurements?
• 1 meter = 3.28 feet
• 1 meter = 100 centimeters
• 1 centimeter = 10 millimeters
• 1 square meter = 10.764 square feet
• 1 foot = 30.48 centimeters
• 1 foot = 12 inches
• 1 inch = 2.54 centimeters
How to calculate the tile coverage area?
Please see the ‘Tile Calculator’ on this web site.

What technologies are used in the manufacture of ceramic tiles?
Roto color technology
Screen Printing
What is Roto color technology?
Roto Color Technology is an advanced printing technology and is used by all European manufacturers of premium tiles. Tile designs are pressed onto the tiles by using large rollers that print different designs onto each tile, as the tile moves underneath the roller. The gradual sideways movement of the roller ensures that each and every tile has its own unique pattern.
Nitco was the first Indian ceramic tile manufacturing company to introduce/ adapt such technology.
What is screen printing technology?
During this procedure, a screen is placed above each tile, after which, paint is pressed through the pores of the screen and onto the tile.
With this technology tiles of the same shade or series look the same, because they use the same screen.
What does the manufacturing process involve?
1. Different kinds of raw material are put inside a giant ball mill to convert the mixture of clays and liquids into a liquid form called “slip”, or ”slurry”.
2. The slip is then sprayed into a giant cylindrical oven, which converts the liquid into a fine dust.
3. The dust is mixed with coloring agents & then pressed at high pressure to give a required shape & size.
4. The pressed tiles are passed into a dryer to remove residual moisture in the tiles, thus making it suitable for glazing and decoration.
5. Tiles are moved into the firing kiln with a temperature of approx. 1200 C. This enables the tile to gain its required solidity.
6. The tiles are cut into the required size, passed through a quality check and are finally packaged. During the quality check, tiles are ranked according to their quality under the following grades; A,B,C D (A being the best quality).
What technology is used for making vitrified tiles?
Soluble Salt (SST)
Double Charge (DCH)
Full Body
Micro Powder a.k.a. Dry Application Powder
Hi-Coat Nano Technology
What is soluble salt technology (SST)?
SST is an old and cheaper technology and is meant for tiles placed in low traffic areas. In this process, the yet unfired tile body is given a liquid color screen-printing to create the design on the tile.
It is called Soluble Salt Technology because soluble salt is used for giving the tile a particular pattern and color. For instance, our Diamond series is made with the use of SST.
With this technology 2 - 2.7mm print are penetrated into the tile. Once the tiles have been fired and polished in order to create a glossy surface, approximately 0.7mm of the soluble print is shaved off, leaving a total print penetration of only 1 to 2 mm.
What is Double Charge (DCH)?
Double Charge technology is far more advanced than SST. Our Ultra Charge & Super Charge series use DCH technology.
This technology uses granules in order to create different shades. Tiles using this technology are ideal for high-traffic areas.
What does “Full Body” mean?
This refers to a manufacturing process as a result of which, the design is not merely on the top surface of the tile, but runs throughout the entire tile. The Tropicana tile, for instance, is a full body tile.
What is Micro Powder (a.k.a. Dry Application Technology)?
This technology is one of the latest tile manufacturing technologies and is also known as random powder technology. Nitco is the only company in India to use dry application technology (a.k.a. Micro Powder).
With this technology, dry color powder is pressed onto the tiles.
This technology allows for a very natural look and also greater resistance to wear and tear. The tiles also keep their bright color for very long.
Because of their high abrasion resistance, they are fit for use in high traffic areas such as malls, multiplexes, hospitals, commercial complexes, IT parks, shops, offices, etc.
What is Hi-Coat Nano Technology?
The HiCoat system is an anti-stain treatment for the protection of porcelain tiles. Once the HiCoat treatment has been applied, the surface of the tile becomes resistant to staining and dirt.
A non-hazardous chemical compound is pressed into the micro porosities of the tile surface. As a result, these pores become permanently sealed, giving the tile an everlasting protection against stains and dirt accumulation.
What are Nitco Le Studio showrooms and why are they so special?
Le Studio Showrooms
We are not merely innovative in our product design and manufacturing process, but in all aspects of our operations. An example of this is our much prized showroom concept.

Polished Marble Laying Instructions
When the marble slabs arrive on site, stack them upright on timber, to protect the edges from chipping. Also, make sure that the slabs are kept out of the rain.
Ensure that the floor to be tiled has been polished to a smooth finish. If the floor is new, it should be left to dry for at least six weeks.
Because marble is a natural product, there will be variation in the color and no two slabs will look the same. Therefore, it is important to lay the slabs out in front of you before you start, to ensure that you will be satisfied with their appearance. Chipped slabs can be used at the edge of the surface you are applying them to.
Clean the surface onto which the marble is to be applied. Then spread cement paste onto this surface so it becomes a level surface with a thickness of 3-5 cm.
Place the marble slab onto the layer of cement and gently tap it with a rubber hammer, in order to create a good grip between the marble, the cement and the surface onto which it is being applied. The gaps between the marble slabs should be very small (between 0.5-1.5mm).
Seal the joints between the marble slabs only 48 hours after installation. This is necessary in order to allow the cement to dry and create the necessary grip between the slabs. When filling the joints between the marble slabs, slightly wet cement should be used. Then apply dry cement to ensure that the filling in the joints will hold. Wipe the surface of the marble slab first with a wet cloth and then with a dry cloth in order to ensure that the surface is completely clean.
Every 3-4 years you may wish to have your marble surfaces polished, in order to achieve the desired shine. Please contact your local marble dealer and they will arrange for professional marble polishing.
Note: This information is offered only as a guideline. No warranty is implied. For best results, please hire a professional and experienced marble installer.
How to install the Mosaico ceramic border
For proper laying of the Mosaico ceramic border, we suggest that you hire an experienced tile mason, preferably one recommended by a Nitco authorized dealer or a Nitco sales person.
Nitco mosaics are pre-assembled and supplied ready-to-lay. There is therefore no need to remove the mesh or covering before laying. Ideal for floor and wall decoration, Mosaico ceramic borders can be combined with all types of tiles.
For laying Nitco Mosaico ceramic borders onto existing tile/cement flooring, the existing floor surface should be chipped with a sharp tool to make the surface sufficiently rough in order for it to grip the mortar. When laying Nitco Mosaico ceramic borders on existing tile/cement flooring, a chemical adhesive ought to be used instead of mortar. In such a case the adhesive manufacturer’s instructions should be followed. However, in case of non-availability of adhesives, the cement-sand mortar should be used.
Before spreading the mortar, have the ground cleaned thoroughly by removing dust, loose particles etc. If the floor is dry, please make it slightly wet. The sand to cement ratio of the mortar should be 3:1. The mortar should be spread to a thickness of approximately 20-25 mm.
Before laying, please ensure that the back of the Nitco Mosaico ceramic borders are completely coated with a thin layer of mortar, as this will facilitate adhesion. Once placed on the mortar bed, the Nitco Mosaico ceramic border should be gently tapped to ensure full contact between the border and the mortar. If air pockets are present underneath the borders, there will be a risk of breakage. In order to ensure that there are no air bubbles beneath the surface of the tile, tap the surface of the tile (e.g. with the wooden end of a tool such as a hammer). If you hear a hollow sound, then remove the tile and apply a further amount of mortar at the place of the air pocket.
After the Mosaico ceramic border has been laid, please clean the joints thoroughly with a brush, in order to remove loose mortar before it dries up. For the Mosaico ceramic border to dry properly, it is essential to allow a 24-hour setting period.
Before applying the grout, all mosaic pieces must be firmly set within the cement bed. Apply the grout in diagonal motion with a hard sponge. Then let it set for about 10-15 minutes before washing away any excess grout. It is important not to let the grout set on the surface of the mosaico ceramic border. The level of the grout should be slightly below the surface of the mosaico ceramic border. Wash away any excess grout by lightly rubbing a damp sponge in circular motion across the surface of the border.
Allow the grout to set for at least 72 hours before use. Ready-made colored grouts are available on the market. When using these, the manufacturer’s instructions should be followed.
Note: This information is offered only as a guideline. No warranty is implied. For best results, please hire a professional and experienced mosaico installer.
How to install Nitco Mosaic sheets
Apply to the ground, a good quality latex-modified adhesive, approved for use with mosaic tile sheets. Please see the adhesive manufacturer’s instructions. Please also ask your Nitco authorized dealer as to where you would be able to purchase the adhesive.
The adhesive should be spread onto the ground, using a 3/16" v-notched trowel. Apply the adhesive to the surface with a back-and-forth scraping motion in order to create good contact between the adhesive and the surface onto which it is to be applied. Because the adhesive will dry within 10 to 15 minutes, please apply the adhesive only to as much area as you can work with in 10 to 15 minutes.
Then, with the straight edge of your trowel, spread a layer of adhesive on the fiber mesh side of the mosaic sheet. This step is called “back-buttering” and assures complete adhesion between the mosaic sheet, the adhesive and the surface onto which the mosaic sheet will be applied.
When back-buttering, it is common for adhesive to push through the mosaic mesh and rise above the surface of the mosaic pieces. It may therefore be advisable to use an adhesive with a similar color as the mosaic pieces being applied. If this cannot be found, make sure that no adhesive dries onto the surface of the mosaic pieces.
The mosaic sheets should then be placed immediately on the surface onto which the mosaic is to be applied. If this step is delayed, the adhesive may dry and the mosaic will not properly grip to the surface.
Make sure that the mosaic sheets are applied in the way you want them to be applied and then gently tap the surface of the mosaic with e.g. a block of wood to ensure that the mosaic will completely grip onto the surface. Make sure that the individual mosaic pieces are level. The tapping will prevent air bubbles from being trapped between the adhesive and the mosaic pieces and also that the mosaic pieces are flat/level. After 24-48 hours, the adhesive will have dried and the mosaic mesh will be ready for grouting.
Use a nylon bristle brush, a sponge, and warm water to clean the surface of the mosaic pieces. If necessary, use a utility knife to carefully remove any excess adhesive from the joints.
With a hard and flat tool, spread your prepared grout at a 45-degree angle, diagonally across the bed of mosaic. After grouting the area, wait 20 minutes before you start to clean away any excess grout.
Then wipe away any excess grout, first with a dry cloth and then, with a sponge and warm water. The less water you use, the better, as too much water can weaken the grout before it sets. Once the surface looks clean, wipe the surface once more with the warm and moist sponge, in order to reduce the possibility of a thin film of grout drying on the surface. Now, allow the surface to dry for 15 minutes, and then lightly rub the surface with a soft cloth, until it is shiny. If you wait any longer to clean and make the surface shiny, a thin layer of grout haze will become difficult to remove.
Once the installation is completely dry (after 24-48 hours) you can safely clean any remaining grout haze or residue with a tile cleaner and scrubbing pad. Please refer to your Nitco authorized dealer, as to which tile cleaning liquid should be used. Once the surface of the mosaic is completely clean and dry, apply a sealant chemical grout with a good quality sealant to prevent staining.
Sealing material is a chemical, which is applied to the surface of a tile in order to protect the tile from damaging chemicals. Sealing materials are recommended for use on unglazed surfaces such as the clay pavers, terracotta, antique stones, stone mosaics and rough porcelain tiles. Application and maintenance should be as per the manufacturer’s directions. Under normal conditions, sealants will normally last for three to four years.
Before applying a sealant, make sure that the surface is clean and dry. The sealant can be applied by sponge or cotton cloth. For added protection, a second and third layer of sealant can be applied, The second or third coating can be applied after a gap of 3-4 hours of each coat. Do not walk on the tiles until the sealant has dried.
Note: This information is offered only as a guideline. No warranty is implied. For best results, please hire a professional and experienced mosaic installer.
General tile laying instructions
The surface of the floor must be plastered and left to dry for at least 2 weeks.
Before laying the tiles, ensure that the tiles have the look you, which you expected/wanted them to have and that they are laid in a way that you wanted them to be laid.
When laying glazed porcelain tiles, please adhere to the following instructions: The cement and sand mortar must be in a ratio of 1:4.
Enough water must then be added in order to create a consistent paste.
Please do not add any further water once the mixing procedure has been completed. Please use the mixture within one hour.
Over an area of 1 square meter, apply approx 20-30 mm of the cement.
Also, smear a layer of cement under each tile. Take time during this process and repeat this process for every new square meter.
In order to ensure a strong grip between the tiles, the cement and the floor, press the tile down with moderate pressure, using your hands or some other object, which won’t scratch the tiles. In order to ensure the precision of the process, please use an instrument to check that each tile is being laid completely horizontal.
Once placed on the mortar bed, the tile should be gently tapped to ensure full contact between the border and the mortar. If air pockets are present underneath the borders, there will be a risk of breakage. In order to ensure that there are no air bubbles beneath the surface of the tile, tap the surface of the tile (e.g. with the wooden end of a tool such as a hammer). If you hear a hollow sound, then remove the tile and apply a further amount of mortar at the place of the air pocket.
We advise you to keep a gap of 1mm to 2mm between tiles because of thermal expansion.
Once the tiles have been laid, please leave them untouched for three to four days, so that they may dry.
Once the tiles have dried for four days, fill the joints with grout.
Before grouting, all the tiles must be firmly set, and all spacers should be removed. Ready-made colored grouts are available (Laticrete/Roffe/Bal Johnson) for floor as well as wall grouting. Please follow the manufacturer’s instructions.
Apply the grout in a diagonal motion with a hard sponge and let the grout set for ten to fifteen minutes before washing away the excess grout. Use a moist sponge in a circular motion to wash away any excess grout. Then dry the surface of the tiles with a dry cloth. The level of the grout should be slightly below the level of the tile. Do not let the grout set on the tiles. Do not use acid on the tiles.
After wiping away any excess grout, allow the grout to dry for a minimum of 72 hours. Your tiles are now ready to be enjoyed.

Sealing – for added protection of the tiles
Sealing material is a chemical, which is applied to the surface of a tile in order to protect the tile from damaging chemicals. Sealing materials are recommended for use on unglazed surfaces such as clay pavers, terracotta, antique stones, stone mosaics and rough porcelain tiles. Application and maintenance should be as per the manufacturer’s directions. Under normal conditions, sealants will normally last for three to four years.
Before applying a sealant, make sure that the surface is clean and dry. The sealant can be applied by sponge or cotton cloth. For added protection, a second and third layer of sealant can be applied. Please allow a gap of 3-4 hours between each coating. Do not walk on the tiles until the sealant has dried.
