Sandstone and limestone are the two stones we are asked to compare most often for outdoor paving. Both are natural, both come from Rajasthan, and both look good in a garden or courtyard. They behave differently, though, and the right choice depends on where the stone will be laid and how it will be used.
How The Two Stones Are Formed
Sandstone is made of sand grains, mostly quartz, pressed and bound together over a very long time. That grain gives it a slightly rough surface, even after cutting.
Limestone is made mostly of calcium carbonate. Indian limestones such as Kota stone are fine-grained and dense, so they have a smoother, more even surface.
Side By Side Comparison
| Point | Sandstone | Limestone |
|---|---|---|
| Surface | Grainy, with natural texture | Smooth and even |
| Grip when wet | Good, especially in natural finish | Good in natural finish, low when polished |
| Colours | Wide range: red, buff, mint, yellow, grey, multi-colour | Narrower range: blue-grey, brown, yellow, black |
| Water absorption | Higher, so sealing is advised | Lower in dense stones such as Kota |
| Reaction to acids | Low | Acids such as lemon juice or vinegar can mark the surface |
| Look over time | Weathers and softens in colour | Keeps an even, plain look |
When Sandstone Is The Better Choice
Choose sandstone when the look matters as much as the use. The colour range is much wider, and the natural texture suits gardens, patios, pool surrounds and pathways where people walk barefoot or in wet shoes.
Our sandstone range includes Mint Fossil, Dholpur, Mandana Red, Rainbow, Teak and Kandla Grey, among others. Because sandstone takes in more water, we suggest sealing it in areas with heavy rain, frost or oil stains.
When Limestone Is The Better Choice
Choose limestone when you want an even, clean look and a hard-wearing surface at a sensible cost. Kota stone is widely used for verandas, parking areas, factory floors and long corridors.
Keep limestone away from places where acids are spilled often, such as outdoor kitchens, unless the surface is sealed. You can see Kota Blue, Kota Brown, Tandur and others in our limestone range.
Thickness For Outdoor Paving
For paving, thickness matters more than it does indoors. Areas that only take foot traffic, such as garden paths and patios, are usually laid with thinner slabs. Driveways and parking areas need thicker stone, because vehicles put much more load on each slab.

Our Honest Answer
There is no single winner. If you want colour, texture and grip around a garden or pool, sandstone is usually the better fit. If you want a plain, even and durable floor for a large area, limestone usually wins.

Questions Buyers Ask About Paving Stone
Which Stone Stays Cooler In The Sun?
Lighter colours stay cooler than dark ones, whatever the stone type. For pool surrounds and terraces in hot places, pick a light sandstone such as Mint or a light limestone shade, and avoid black or dark red stone.
Can I Mix Sandstone And Limestone In One Project?
Yes. Many projects use limestone for the main floor and sandstone for borders, steps or garden paths. Keep the thickness the same where the two stones meet, so the surface stays level.
How Long Does Natural Stone Paving Last?
Laid on a proper base with the right thickness, natural stone paving can last for decades. Most early failures come from a weak base or slabs that are too thin for the load, not from the stone.
