The four stones in plain words
Red stone is the deep brick-red sandstone you see on old forts and temples. It has a strong colour and a fairly rough, natural face. Dholpur stone is lighter, usually cream, beige or soft pink, and is known as a dense, hard stone with a fine grain. Bharatpur stone runs from pink to light red and buff and is widely used for jaali work, carving and cladding. 'Sandstone' on a rate list is often the general beige or mixed-colour stock.
Colour and hardness vary from quarry to quarry and even block to block. Always look at the actual slabs, not just a photo, and ask which quarry the lot came from.
Quick comparison
| Stone | Typical look | Hardness and density | Best fit |
|---|---|---|---|
| Red stone | Deep red, earthy | Medium, can be softer in some lots | Cladding, boundary walls, outdoor paving, steps with a rough finish |
| Dholpur | Cream, beige, light pink | Generally dense and hard | Flooring, steps, driveways, high-traffic areas |
| Bharatpur | Pink to red and buff | Medium, easy to cut and carve | Wall cladding, jaali, elevation, garden work |
| Sandstone (mixed) | Beige, brown, mixed | Varies a lot by lot | Budget flooring, paving, boundary and landscaping |
Water absorption: what the number tells you
A lower water absorption means a denser stone. Dense stone stains less, grows less moss, and is less likely to show white salt marks (efflorescence). A more porous stone drinks water, so it needs a better sealer and care near wet areas like bathrooms and the base of boundary walls.
Do not trust a general claim that one stone is always better. Ask the supplier for a test report if the job is large, or do a simple check: put a few drops of water on an unsealed offcut and see how fast it darkens and soaks in.
Where each one fits
- Flooring inside the house: Dholpur or a dense sandstone with a honed or lightly textured face.
- Steps and entrance: a hard stone with a natural, flamed or sandblasted face. Avoid polished faces outdoors.
- Wall cladding and elevation: Bharatpur or red stone, thinner cut pieces are fine since they carry no load.
- Boundary walls: red stone or rough sandstone, with a damp-proof course at the base so rising damp does not stain the stone.
- Garden paths and parking: thicker, harder slabs. Thin slabs crack under vehicles.
Slip and maintenance
Polished and honed stone becomes slippery when wet. For bathrooms, balconies, ramps and steps in the rain, choose a natural, brushed, flamed or sandblasted surface. Add a nosing or a rough strip on stair edges for elders and children.
Sweep and mop with plain water or mild soap. Skip acid cleaners, because they eat the surface of sandstone. Reseal outdoor stone every couple of years, or when water stops beading on it.
Laying and sealing checklist
- Lay on a firm, level base such as PCC or a compacted bed, not loose fill.
- Soak or wet the stone back before laying so it does not pull water out of the mortar.
- Use a cement-sand bed, commonly 1:4, and keep joints even, about 3 to 5 mm.
- Treat the back of the slab with a sealer or bonding coat where staining is a concern, since mortar moisture can stain the face.
- Let the floor cure, then clean off mortar. Apply a penetrating sealer only after the stone is fully dry, as per the sealer label.
- Order 5 to 10 percent extra for cutting and breakage, and keep a few spare pieces for repairs.
Before you order
Visit the store, see the actual slabs in daylight and wet a corner to see the true colour. Tell us the area, thickness you need and whether it is indoor, outdoor or a driveway, and we will suggest what suits. Rates change by lot and size, so call or WhatsApp for the current quote.
Frequently asked questions
- Which is the hardest of these stones?
- Dholpur is generally the dense, hard one, but quality varies by quarry and lot. Judge the slabs in person.
- Is red stone good for flooring?
- It works well outdoors and on steps with a rough finish. For indoor floors most people prefer Dholpur or a dense beige sandstone.
- Does sandstone need sealing?
- Outdoors and in wet areas, yes. A penetrating sealer reduces staining and moss. Follow the product label.
- Which finish is safest on wet steps?
- Natural, flamed or sandblasted. Polished stone is slippery in the rain.
