Orchid Surfaces — a Malujiwala brand
A three-part acid-proof epoxy for bedding and jointing Mandana stone, Kota stone and acid-resistant tile. Made for floors that get inspected — pharmaceutical, dairy, food and chemical plants.
Mandana is a dark red sandstone that resists acid on its own — which is why it has been the default industrial floor in Indian chemical and pharmaceutical plants for decades. But the stone is only half the floor. The joints between the slabs are where a floor is actually won or lost. If a joint stays porous, acid, effluent, milk or product residue works its way down to the screed, and the floor starts failing from underneath where nobody can see it.
An epoxy grout removes that path. It arrives as three parts — resin, hardener and a graded filler — proportioned to be mixed on site. There is no cement and no water anywhere in it. Once cured, the joint is a hard, non-porous solid that does not shrink back from the edge of the slab, bonds to stone, concrete and brick, and can be scrubbed with soda ash and hot water without opening up.
The same material is used two ways: as a bedding mortar to set the stone, and as the jointing compound between slabs. It is equally at home on Kota stone, acid-resistant brick and tile, vitrified tile, granite and marble — Mandana is simply the floor it gets asked for most.
Most of the people who buy this are not buying on price. They are buying because someone is going to walk their floor with a clipboard, and a joint that has opened up is not a conversation they want to have.
A cured epoxy joint is non-porous and flush with the slab. There is no open grout line holding product, no soft edge crumbling at the arris, and nothing that has to be raked out and refilled every year.
Floors in audited plants are not cleaned gently. Caustic wash, soda ash, hot water and repeated scrubbing are what actually destroy a cement-based joint over a couple of years. Epoxy is specified precisely because it takes that treatment.
Ask us for the technical data sheet and the safety data sheet before you write the specification, so your quality team can read the wording against your own protocol rather than taking our word for it.
No product passes an audit on its own — the floor system and its paperwork do. Material, joint detail, coving, drainage falls and workmanship are all inspected together. We would rather say that plainly than print a compliance claim on a web page.
Production halls, granulation and wash bays, corridors and utility areas where the floor is part of the hygiene case.
Milk that seeps into an open joint does not evaporate — it sits, sours and breeds. A sealed joint is the whole point of an acid-resistant floor here.
Acid handling areas, effluent channels, tank farms and bund floors, laid on Mandana or acid-resistant brick and jointed with epoxy.
Where spilled acid would otherwise track through the joint and lift the floor off its bed within a few seasons.
Also used on laboratory floors, commercial kitchens, cold stores and any Kota or Mandana floor where the client simply does not want the grout lines going grey and soft.
Send us a site photograph or the floor drawing and we will tell you what the joint detail should be before you order anything.
Written for the crew rather than the specifier. Acid-proof floors fail at the workmanship stage far more often than at the material stage.
Sound, clean and dry. Laitance, curing compound, old grout and oil all have to come off first — epoxy bonds to the substrate, not to whatever is lying on it. Falls to drain are fixed at this stage, not later.
The three parts are proportioned as supplied. Splitting a kit by eye is the single commonest cause of a joint that never hardens properly. Mix resin and hardener first, then bring in the filler.
Once mixed, the material has a working window and it shortens as the site gets hotter. Mix what the crew can place in that window and no more. Confirm the pot life for your site temperature before you start.
Place with a rubber or steel trowel, pack the joint out to full depth and finish the last pass diagonally across the joints so they come up flush rather than hollow.
Residue left on the face of a Mandana slab is easy while the material is fresh and a serious job once it has gone off. This is the step contractors judge an epoxy on.
Foot traffic, then wheeled loads, then chemical exposure — each has its own waiting period. Do not hand the floor over to washdown early; that is where a good installation gets spoiled.
We publish what we can stand behind and leave the rest to the data sheet, which is issued against the batch you are actually buying.

Most acid-proof floors in India are assembled from three separate purchases: a stone vendor, a chemicals dealer and a labour contractor. When the joint width does not suit the slab, or the grout quantity runs short halfway through a shutdown, the three of them explain it to each other while the plant waits.
We manufacture the Mandana stone at our own units and supply the epoxy alongside it, so the slab thickness, the joint detail and the material quantity are worked out once. Laying and fixing labour can be arranged anywhere in India, charged separately, with our own manpower at site.
That is the reason to buy this grout from us rather than the cheapest one on the market. It is not the cheapest, and it was never priced to be.
It is an epoxy grout used to bed and joint Mandana stone flooring. Mandana is a naturally acid-resistant red sandstone, but the stone is only half the floor — the joints between the slabs decide whether acids, effluent, milk or product residue can reach the screed underneath. A three-part epoxy (resin, hardener and graded filler) sets into a hard, non-porous joint with no cement and no water in the mix, so there is nothing for liquid to soak into.
Acid-proof cement and silicate mortars are cheaper and still widely used, and on a lightly loaded floor they work. The difference shows up over time: a cement-based joint stays porous, absorbs whatever is spilled on it and eventually gives ground at the arris of each slab. An epoxy joint does not absorb, does not shrink back and can be scrubbed with soda ash and hot water without opening up. On floors that get inspected, that is usually the deciding factor.
Yes. The same grout is used on Kota stone, acid-resistant bricks and tiles, vitrified and ceramic tile, granite and marble. Mandana and Kota are simply the two floors it gets specified for most often in India.
No single product passes an audit — the floor system and its documentation do. What an auditor looks for is a joint that is non-porous and cleanable, no harbourage points at the coving and drains, and paperwork that matches what was actually laid. Ask us for the technical data sheet and safety data sheet before you write the specification, so your quality team can check the wording against your own protocol rather than taking ours.
No, and it is not meant to be. There are cheaper three-part epoxies on the Indian market and they will fill a joint. This one is bought by plants that would rather not reopen a floor during a shutdown, and by laying contractors who care how the material handles on the trowel and how easily the residue comes off before it cures.
That is the usual order. We manufacture the stone at our own units and supply the grout alongside it, so the slab thickness, the joint width and the quantity of grout are worked out once, by one supplier, instead of being reconciled on site between a stone vendor and a chemicals dealer.
Yes, anywhere in India. Laying and fixing labour is arranged and charged separately, with our own manpower deployed at site. Acid-proof floors go wrong at the workmanship stage more often than at the material stage, so this is worth asking about even if you buy the material elsewhere.
It depends on the slab size, the joint width and the joint depth — a 4×2 ft Mandana slab laid with a narrow joint uses far less per square foot than small-format tile. Send us the slab size, the thickness and the total area and we will work the quantity out for the job rather than quoting a general figure.
Across India by road, from our units in Rajasthan, and by container for export. Domestic orders are quoted either ex-works or FOR delivered to your site; export is quoted on request.
Yes — Mandana stone slabs, tiles and cobbles are our own manufacture, and Kota stone as well. Both are supplied to industrial floors across India.
Tell us what the floor is and we will come back with the grout quantity, the delivered price and the data sheet — and if you want the stone and the laying crew as well, that is quoted in the same reply. Most enquiries are answered the same day.
Four manufacturing units in Rajasthan, a direct line from quarry to site, and one supplier answering for the whole floor.
