Kota Stone Flooring | An Architect Explains

Kota Stone is a fine-grained variety of limestone obtained from Kota, Rajasthan, India.  It is available in attractive, earthy colours. It is non-slippery, water-resistant, non-porous, can be rough finished or polished to a high shine. However, it does not have the sophisticated appearance of Marble or Granite. It is more rustic looking. It is used both in interiors and in exteriors, commercial spaces, external staircases, pathways, corridors, driveways, and balconies etc. A very similar stone is the Shahbad stone found in North Karnataka. But Shahbad is mostly grey.
Kota stone is a natural stone that can be easily maintained and is used both indoors and outdoors
 WHAT ARE THE CHARACTERISTICS OF KOTA STONE?
Composition: Kota is a very fine grained, siliceous calcium carbonate rock of sedimentary nature.
Physical properties: Kota is hard, compact, tough and homogenous natural stone. It is non-slippery.



WHAT ARE THE ADVANTAGES OF KOTA STONE FLOORING?
Beautiful: Polished Kota Stone looks beautiful because of it’s nice smoothness and shine.
Natural: Like Marble or Granite, Kota is a natural stone and is bio-degradable and a green option.
Finish: Kota stone can be finished according to requirement such as one-side honed, both-sides honed, hand cut, machine cut, polished, mirror finish and calibrated etc.
Hygienic: Kota, being non-porous and moisture resistant, is a hygienic flooring option in humid regions.
Cool: Kota reflects heat and is always cool and comfortable underfoot.
Affordable: Unlike Marble or Granite, Kota stone is very affordable. In fact it is the cheapest stone among other natural stones.
Wide range: Kota is available in beautiful colours  like black, pink, grey and beige. though the rich greenish-blue and brown colours are the most popular.
Kota stone takes a high polish
WHAT ARE THE DISADVANTAGES OF KOTA STONE FLOORING?
Flaking: The stone tends to flake over a period of time. However, periodic polishing using polishing wax can eliminate this phenomenon.
Lustreless: Kota lacks the luster of Marble or granite.
Small sized tiles: Unlike Marble and Granite, Kota is not available as large slabs, due to the brittleness of limestone. The maximum sizes are around 240 cm x 75 cm.
Many joints: Unlike Marble or Granite, Kota stone flooring does not give the appearance of a seamless flooring because Kota tiles are available only in small sized tiles. Also, there is a lot of variation in colour between tiles.
Kota stone is available only in small sizes and hence a lot of joints are visible.
 WHERE IS KOTA STONE FLOORING BEST SUITED?
Due to it’s durability and affordability, it is the most preferred choice among natural stones in large spaces like industries and commercial buildings and homes of eco-conscious people.  It is sometimes used as a wall cladding because of its natural colouring and sheen. A very good alternative to Kota is Shahbad stone or Slate.

    how many polishing need for kota flooring

    Hi Maha,
    At least 5 or 6 times to get a good shine. It also depends on the quality of the stone. Denser stones get a good shine with 4 or 5 polishes.

    Hi Chavda Ashvin,
    Kota is actually one of the most preferred material in external staircases because it does not slip, is water-resistant and cheap.

    Dear Sir,
    we have kota stone Grey color, in our office store & Canteen, Machine polished done, but mirror shining is not came, can we use WAX. which type of wax is suitable.Kindly suggest.
    Hi Prasad,
    Kota stone does not get “mirror shine” unlike marble or granite. Do not use wax as it will make it slippery and also not really improve the shine. But regular sweeping and mopping with water will gradually cause the stone to shine. Then it will have a matured, aged nice shine. But you will have to be patient.

    We are planning to change the flooring of our small bungalow on both ground floor and first floor. We like the Brown Kota stone with variations in colours.
    For interiors like living room etc is it a good choice ? we prefer natural stones rather than the vitrified tiles.
    Also which finish would be ideal ? Mirror Polished or any other for our application?
    Hi Tushar,
    Natural materials are always preferable to manufactured ones. Kota is a good choice. It has to be mirror polished and with regular care and mopping, it will take on a nice natural shine and yet will ot be as slippery as marble. But be aware that kota takes scratches easily, even moving chairs or cots around will cause scratches. So get furniture with rubber shoes.

    What is the difference between kotta stone and sabbath stone.
    Hi Rathi,
    I think you are referring to shahbad stone, a variety of limestone from North part of Karnataka bordering Andhra Pradesh. Generally available in grey shades it is easy to work with and economical, lasts long without surface blemishes and easy to maintain. Kota is also very similar in its composition, but has a different colour, (more greenish) and takes scratches. However, regular mopping imparts a very good shine. It is also more easily available.

    Hello sir
    We are planning to use kota glossy polish and leather polish olive green stones. After glossy polish or leather polish it will be slippery or even after polish also it will be un slippery.
    In winter stone will be more cool than marble or granite or it will be warm.
    Pl advise
    Hi Azad,
    Glossy polish will make any stone more slippery, when it is wet. Leather polish is more rough and makes it less slippery. I believe Marble is colder in winter than Kota.

    hello there sir. I appreciate this article. I’ve been recommended by my architect to go for Kota stones as a flooring option. after some research, i seem to like it. but all the granite or stone dealers are surprised when I say it’s for interiors. my contractor is unsure about its usage inside home too. id certainly need your advise as I have to decide soon. is it a good option to have Kota and it’s leather finish (bedroom only)all over the home (living, bed, kitchen)
    Hi Ram,
    Kota stone is very earthy looking and has a good sheen when polished properly. But its biggest disadvantage is that it takes scratches very easily. Even if you drag a chair, it leaves marks. So in the long run there will be scratch marks in areas of high traffic. But repeated mopping makes it shine even more. So if you are not too bothered about scratches, it is a very nice flooring option in a house. We have used it in some of our projects and it has a kind of rustic and earthy charm. Also it is much cheaper than granite or marble.

    Different grades are used. You will have to ask the polishing person regarding the grade and the polish that you require.

    I have recently laid about 800 rough kota stones (22″ x 22 ” on my driveway in Delhi (total area 3200 sq ft) with Udaipur Green Marble strips 4 inches wide (total 1000 Rft). I need to keep my driveway cleaned regularly. Manual cleaning with a brush takes very long. Can you suggest – but no too expensive – options?

    You could try some high power jet water sprays (Bosch) to clean the driveway.

    Hi, Wonderful article on Kota. Could you tell me what is the thickness available. Could this be directly laid on top of vitrified tiles. Don’t somehow like the feel of vitrified tiles for my new apartment.
    Thanks,
    Arun
    Hi Arun,
    Kota stone is around 20mm to 1 inch thick. It cannot be laid on vitrified tiles. It needs to be laid on a bed of cement mortar and then ground and polished.

    Hi,
    Thanks for a nice article. We have Kota Stone flooring in our compound and the surface has small pores or pit types. Can these pits be filled during polishing? Is it possible to use pure cement in anyway to fill these small pores?
    Thanks in advance for your advice.
    Hi Prabhakar,
    It looks like lower quality kota stones since it is used in the outside. There is no point in trying to fill the pits with cement as it will look shabby and even come off. However polishing might help to smoothen it a bit. But remember it may make the kota too smooth and slippery.

    Regards,

    Hi Ravi Agarwal,
    Shahbad and kota are almost similar in composition and properties – so you can opt for either one. Since shahbad is available nearby it makes sense to go for that.

    Hi Sumit,
    The best option is to go for terracotta tiles as they reduce the heat and are easy to maintain. But make sure you opt for good quality ones as otherwise they may crack and cause leaks inbto the terrace slab. price depends on the quality.

    I am trying do Kota flooring in my living room. How do I determine if what I am getting is a good quality?
    Also I wanted a honed finish? Is that appropriate for indoors?
    Is it possible to get honing easily in Mumbai.
    Hi Diksha,
    Take your floor layer when you go to select the kota stone. He will be able to choose a good lot. You can get the finish you want depending on the number of polishes of the stone.

    can we use kota stones for the bathroom floor? How often do we need to polish the floor to avoid flaking? How much would be the cost per sq ft for Kota stone? How to choose good quality stone by looking?
    Hi Glester,
    You can use kota with rough/honed polish in a bathroom. But it is a porous material and will absorb moisture and there will perpetually be damp spots if used in a bathroom.

    also what should be the size of kota for kitchen ,living room.
    is brown difficult to get.
    i am finding it difficult to get the right lime for construction .
    Hi Mumtaz,
    Lime is a very good material but it is difficult to get and even more difficult to get masons who know how to use it right. Kota is a good option. 1’6″x1’6″ or 2’x2′ sizes are good. Bigger sizes are much more expensive.

    Hi,
    NEED YOUR ADVICE ON..
    We are thinking of replacing cement flooring with Kota Stone for the entire Group Housing Society in Delhi.. Sir, Do you recommend Kota stone flooring for car parking etc.. to the best of my knowledge 99.9% society in delhi has Cement flooring as this is cheaper and more durableas compared to Kota Stone. We already have cement flooring in our society now thinking to put Kota stone above that.. NEED YOUR ADVICE SO THAT WE CAN TAKE RIGHT DECISION.
    Hi Subodh,
    Kota is definitely more durable than cement flooring and once laid can last for a long time. Cement floor gets chipped over time. But it is way cheaper than kota. So you have to take the decision based on your preferences and cost factors.

    last point what i understand that following are the disadvantages of Kota stone flooring when it is used for car parking where all shorts of vehicle will be passing everyday.
    • It is not available in big slab sizes like marble or granite. Kota is a variety of limestone which is very fragile hence it is available in smaller sizes.
    • Continuous usage of Kota stone might result in flaking. However if it is well maintained and polished regularly flaking of the stone might be prevented.
    • Its surface finish is not so lustrous as marble or granite.
    Hi Subodh,
    Kota is not a fragile stone but quite strong and can withstand heavy traffic. Only that it is porous, so it can flake and chip easily. All the other points you mentioned are spot on.

    What would be the difference in the cost for 1000 square feet flooring area – Kota stone flooring vs Cement flooring?
    Hi,
    Basic Cement flooring will cost about Rs 50 per sq.ft. whereas Kota will cost about Rs 150 per sq.ft. This is an average estimate. It may go up or go down depending on the type of Kota used and the specifications of the cement flooring.

But my contractors and family members are insisting on italian marble or vitrified. I want my house simple and rich. Can you please guide me in deciding which tiles shall i go?
    Hi Sumit,
    Kota is a good choice. However it takes scratches and in that regard marble or vitrified tiles are better options. Italian marble gives a very posh appearance and is very expensive. You could opt for indian marble which is quite good.

    Sir, my house has kota stone flooring for the past 14 years. There’s a problem and need your advice. In the living room area the distilled water from the UPS, which is acidic has overflown from the battery on to the tiles. This has seeped into the tiles and about 3 to 4 tiles have become black and it looks bad. My question to you is can I get these few tiles polished and will it help? Or is it possible to just remove those few tiles and change them? Kota stone flooring has flaked in a few places. Overall would it be a good idea to retain it as it is or go in for a flooring like vitrified or anything else more manageable. Please share your thoughts. Thank you.
    Hi Archana,
    The blackened tiles cannot be salvaged even with plishing since acid has affected them. So it is better to get them replaced with new stones. However, there will be a difference between the existing and the new stone in colour. If the stones are flaking and they look bad, you could think of changing the whole floor.

    Dipti
    Hi Dipti,
    The tile layer will be able to adjust the thicknesses in the cement mortar so that the final surface is one level. Then after that you should polish the floor 5-6 times to get a uniform level.

    Hi, have a few questions –
    a. your article above says Kota stone is non-porous (consistent with other information on the internet) whereas several responses from you noted above indicate that it is porous, can you please clarify.
    b. I am considering alternate options to mangalore clay tiles for a terrace of approx 1200 – 1400sq ft. An artcile on houzz recommends a combination of Kota and Jaisalmer stone. What are your thoughts?
    c. If not the above, are there any other alternatives that provide good options for terrace (used as a party + landscaped area + gazebo area)? My concerns with Mangalore clay tiles is that they accumulate moss with moisture and require very high maintenance.

    My key criteria are easy to maintain, good look, anti-skid (non-slippery surface) and heat resistent. Your thoughts and insights are most appreciated
    Hi,
    a) I dont know where I have mentioned that it is porous. iT is similar to marble in composition and hence may get stained.
    b) Kota is not a good option in an open terrace, because it gets pitted over a period of time under the harsh sunlight.
    c) In my experience, I have seen that only good quality clay tiles last long in open terraces because they do not crack, can expand and contract in extreme heat and cold and maintenance-free. Just make sure they are laid with a good gradient, so that water does not stand. that way no moss will accumulate.
