Tandur Grey and Tandur Yellow are two hand-cut and tumbled Indian limestone paving ranges with similar formats but very different colour character. Tandur Grey combines cooler grey, blue-grey and occasional muted green-grey tones, while Tandur Yellow introduces warmer buff, honey, beige, ochre and occasional green movement. The choice is therefore mainly about garden style, surrounding materials and how much natural colour variation is wanted.
Quick Answer: Choose Tandur Grey for a cooler, calmer limestone that works with red brick, pale render, timber and contemporary planting. Choose Tandur Yellow for a warmer, more varied patio suited to cottages, period properties, buff walling, gravel and traditional gardens. Both are available in hand-cut and tumbled formats and should be blended from several packs during installation.
Quick Answers: Tandur Grey vs Tandur Yellow
What is the main difference between Tandur Grey and Tandur Yellow?
The main difference is colour. Tandur Grey is dominated by grey and blue-grey tones, while Tandur Yellow contains warmer yellow, buff, beige, ochre and occasional muted green variation. Their hand-cut and tumbled finish gives both a softer traditional appearance.
Which has more colour variation?
Tandur Yellow generally has broader and more visible tonal movement. Tandur Grey is usually calmer, although individual slabs can still vary in grey, blue-grey and green-grey shades.
Which is better for a traditional garden?
Both work well in traditional settings. Tandur Grey creates a more restrained heritage look, while Tandur Yellow produces a warmer cottage or farmhouse character, particularly beside red brick, buff stone, timber and gravel.
Which works better with a modern extension?
Tandur Grey normally integrates more easily with pale render, anthracite doors, modern fencing and controlled planting because its cooler colour palette is more restrained. The tumbled finish still prevents it from looking overly manufactured.
Do Tandur Grey and Tandur Yellow need the same installation method?
Yes. Both should normally be installed on a stable prepared base using a full mortar bed and compatible slurry primer across the complete underside. Natural thickness and edge tolerances should still be allowed for during laying.

Where Do Tandur Grey and Tandur Yellow Come From?
Both ranges are sourced through the established Tandur limestone supply area in southern India.
Within the current PSU supply context, the two colour selections are associated with different limestone beds within the wider Tandur quarrying system:
- Tandur Grey is selected for cooler grey and blue-grey colour;
- Tandur Yellow is selected for warmer yellow, beige, ochre and related tones.
This supply description should not be interpreted as meaning every product sold under a similar trade name throughout the industry comes from exactly the same quarry face or geological layer.
Naming Note: Kurnool Grey should not be treated as an exact synonym for Tandur Grey. Kurnool is a separate producing area, and PSU uses Kurnool Grey in connection with Dove Grey limestone. Trade names can overlap loosely across the stone industry, so product source, finish and specification should always be checked.
Tandur Grey Limestone Paving
Tandur Grey limestone paving combines light grey, blue-grey and occasional muted green-grey tones with hand-dressed and tumbled edges.
The overall appearance is calmer than Tandur Yellow and generally more restrained than strongly mixed sandstone.
This makes it particularly useful where natural stone character is wanted without strong warm colour movement.
Where Tandur Grey Works Well
- red-brick houses;
- Victorian and Edwardian properties;
- pale render;
- anthracite aluminium doors;
- timber structures;
- grey garden furniture;
- contemporary planting; and
- mixed traditional-modern garden schemes.
Against red brick, the cooler paving creates contrast without becoming as visually severe as black limestone.
Against pale render or dark aluminium, Tandur Grey can create a more modern grey palette while its tumbled edges retain natural character.
Tandur Yellow Limestone Paving
Tandur Yellow limestone paving contains warmer buff, honey, beige, mustard, ochre and occasional muted green tones.
The colour variation is more expressive than Tandur Grey and is one of the principal reasons for choosing the stone.
Where Tandur Yellow Works Well
- cottages;
- period brickwork;
- farmhouse-style gardens;
- buff or honey-coloured walling;
- gravel;
- timber;
- traditional planting; and
- older courtyards.
Tandur Yellow can help a new patio feel visually established rather than sharply new, especially when combined with tumbled edges and mixed-size modules.
Which Has More Natural Colour Variation?
Tandur Yellow normally shows greater visible colour variation.
A single installation can contain:
- soft yellow;
- buff;
- beige;
- ochre;
- mustard; and
- muted green-grey.
Tandur Grey remains variable natural stone but usually stays within a narrower grey, blue-grey and muted green-grey palette.
Neither should be installed one crate at a time without blending.
Open several packs together and distribute the stronger and lighter slabs across the complete area.
Which Looks Lighter?
Tandur Yellow often appears warmer and visually brighter because of its buff and beige content.
Tandur Grey can range from light grey to deeper blue-grey but generally reads as cooler rather than warm.
Actual brightness depends on:
- individual slab selection;
- wet or dry condition;
- sunlight;
- surrounding walls;
- joint colour; and
- surface weathering.
Samples should therefore be viewed outdoors rather than selected from indoor photographs alone.
How Do They Look When Wet?
Water temporarily deepens both colours.
Tandur Grey usually develops richer grey and blue-grey tones when wet.
Tandur Yellow normally develops stronger honey, buff and ochre contrast.
The wet appearance should not be confused with the normal dry colour.
If a colour-enhancing sealer is being considered, test the exact product separately because a chemical enhancer does not necessarily reproduce the same appearance as simple wetting.
Which Works Better with Red Brick?
Both can work successfully but create different relationships with the building.
Tandur Grey with Red Brick
The cool grey and blue-grey paving contrasts with warm brick.
This can make both materials appear clearer and is particularly useful where the garden includes:
- grey joinery;
- black metalwork;
- modern furniture; or
- contemporary planting.
Tandur Yellow with Red Brick
The warm buff and yellow stone creates a more complementary relationship.
This often works particularly well where the intention is traditional rather than strongly contrasting.
Which Works Better with Pale Render?
Tandur Grey normally creates the cleaner and more restrained pairing.
Its blue-grey tones work well with white, cream or pale rendered walls, particularly where dark doors or windows provide another cool architectural element.
Tandur Yellow can still work, but it introduces a warmer Mediterranean or heritage influence rather than a neutral grey scheme.
Which Works Better with Natural Stone Walls?
This depends on wall colour.
For cool grey walling, Tandur Grey generally creates greater continuity.
For buff, honey or warm beige walling, Tandur Yellow often integrates more naturally.
A perfect colour match is not necessary. Controlled contrast can prevent the patio and walls merging into one flat surface.
Which Is Better for a Cottage Garden?
Tandur Yellow is particularly well suited to cottage-style landscaping.
Its warm variation and tumbled edges coordinate naturally with:
- informal planting;
- aged brick;
- natural stone walls;
- gravel;
- timber;
- terracotta pots; and
- traditional furniture.
Tandur Grey can also work in a cottage garden where a quieter stone colour is preferred.
Which Is Better for a Contemporary Garden?
Tandur Grey is normally easier to integrate into a contemporary scheme.
It works well beside:
- anthracite aluminium;
- pale render;
- dark fencing;
- modern furniture;
- simple planting; and
- clean landscape geometry.
However, its hand-cut and tumbled finish still has more visible traditional character than machine-cut Dove Grey or Kota Blue limestone.
If very precise modern geometry is the main objective, a sawn-edge limestone or porcelain may be more appropriate.
Why Do Both Stones Look Traditional?
The appearance comes not only from colour but also from the finishing process.
Both Tandur Grey and Tandur Yellow are commonly supplied with:
- natural split surfaces;
- hand-dressed edges; and
- tumbled finishing.
Tumbling softens sharp arrises and removes some of the freshly cut appearance.
This creates a more aged character than precision-sawn paving.
Jointing Note: Hand-cut and tumbled limestone should not be forced into rectified porcelain-style joints. Joint width should accommodate the actual stone tolerances and the selected jointing compound.
Tandur Grey and Tandur Yellow Sizes
Current PSU ranges include comparable formats in both colours.
| Format | Tandur Grey | Tandur Yellow |
|---|---|---|
| 900 x 600 | Available | Available |
| 600 x 600 | Available | Available |
| Mixed patio pack | Available | Available |
| 200 x 100 setts | Available | Available |
Current PSU collection pages show both Tandur Grey and Tandur Yellow in 600 x 600, 900 x 600 and 22mm nominal calibrated patio formats.
900 x 600, 600 x 600 or Patio Pack?
900 x 600
Choose 900 x 600 where the patio needs longer courses, fewer joints and a more structured layout.
600 x 600
Choose 600 x 600 where square geometry works better with the garden or building dimensions.
Mixed Patio Pack
Choose a mixed pack where a traditional modular pattern is more important than strict geometry.
Mixed packs are particularly effective with Tandur Yellow because the changing slab sizes reinforce its informal heritage appearance.
For both colours, check the exact pack modules before installation rather than assuming all patio packs are identical.
Do Tandur Grey and Tandur Yellow Have the Same Thickness?
Many current PSU Tandur Grey and Tandur Yellow patio products are supplied at approximately 22mm nominal calibrated thickness.
Calibration improves underside consistency but does not make every natural stone slab exactly identical.
The installer must still compensate for:
- natural face texture;
- minor thickness tolerance;
- hand-finished edges; and
- the required final paving level.
Which Shows Dirt More?
The two colours make different types of contamination more visible.
| Issue | Tandur Grey | Tandur Yellow |
|---|---|---|
| Light dust | Often relatively well disguised by mid-grey tones | Can blend into some buff areas |
| Soil | Moderately visible | Can be more noticeable on paler slabs |
| Wet leaves / tannins | Visible depending on slab tone | Can be more obvious on lighter yellow and beige areas |
| Pale cement residue | Can contrast against darker grey areas | Can still remain clearly visible |
| Algae | Visible on both | Visible on both |
No natural limestone colour eliminates maintenance.
Cleaning Tandur Limestone
Both Tandur Grey and Tandur Yellow are limestone and should be cleaned using limestone-compatible methods.
Routine care should begin with:
- sweeping away loose debris;
- removing wet leaves;
- clean water;
- a soft or suitable medium brush; and
- a limestone-safe cleaner where necessary.
Acid Warning: Do not use brick acid, hydrochloric-acid cleaner, vinegar or other acidic products on Tandur limestone. Acid can react with calcium carbonate and permanently etch, lighten or roughen the surface.
Does Tandur Limestone Need Sealing?
Sealing is optional rather than mandatory.
A compatible impregnating sealer may be useful:
- around outdoor dining;
- beneath trees;
- where leaf tannins are common;
- around barbecues;
- where oil or food staining is more likely; or
- where easier routine cleaning is wanted.
A sealer does not make either limestone:
- acid-proof;
- completely stain-proof;
- maintenance-free; or
- immune to natural weathering.
Test the exact treatment on a spare slab before applying it to the complete patio.
How Do Tandur Grey and Tandur Yellow Weather?
Both will gradually settle in appearance outdoors.
Tandur Grey may soften slightly as the surface experiences weather, moisture and normal use.
Tandur Yellow can become visually more blended as its yellow, beige and ochre tones weather together.
Natural ageing should not be confused with:
- acid etching;
- cement contamination;
- algae;
- leaf staining;
- mineral deposits; or
- failed surface coatings.
Installation Requirements
Colour choice does not materially change the core installation method.
Both should normally be installed using:
- a stable compacted sub-base;
- correct finished levels and drainage falls;
- a workable full mortar bed;
- compatible slurry primer across the complete underside;
- joints suitable for hand-cut and tumbled edges; and
- clean installation methods that keep cement contamination off the visible surface.
