Batch information

Porcelain paving is a man-made product crafted in batches and may exhibit variations in colour and texture from batch to batch. This potential variance means that the porcelain you receive upon ordering may differ slightly from the samples sent, or our showroom displays viewed before making your purchase. To maintain product consistency, we advise against combining different sizes as these will inevitably be different batch codes. It is industry standard to allow an additional 10% on all orders.

Should you have any concerns about these variations, please reach out to our sales team for personalised guidance. We recommend keeping note of the โ€˜batch colour codeโ€™ labelled on the packaging of the delivered porcelain. This is a white label of the side of the pallet and also the packing of each individual slab.

While we strive to source the same batch for future orders, this isnโ€™t guaranteed. Therefore, we encourage ordering sufficient quantities initially to maintain uniformity in your project.

**About Our Natural Indian Limestone**

 

Consider our premium Indian Limestone Paving for your propertyโ€™s exterior, whether for a contemporary garden patio, terrace, or pathway. Its elegant, refined appearance makes it suitable for both modern and traditional landscaping schemes. Our limestone is available in a variety of sizes, including single-size packs (600mm x 900mm) and mixed-size patio packs for flexible design layouts.

We offer a diverse range of finishes, including naturally riven textured surfaces and smooth honed limestone, allowing you to match the paving with your personal vision and outdoor aesthetic. Limestone is prized for its subtle veining and consistent tonal variable, producing a rich palette of colours when slabs are laid togetherโ€”no two pieces are exactly alike.

Our Natural Finish limestone slabs are quarried and hand-cut, providing a slightly textured riven surface with crisp, squared edges that add character and refinement to each piece. The timeless appeal and durability of Indian Limestone make it a popular choice among homeowners, garden designers, and landscaping professionals throughout the UK.

The limestone is calibrated to a thickness of 22mm (with a tolerance of ยฑ2-3mm), and features a flat laying side with grooves to simplify installation and create a level, professional finish.

**Important Considerations**

All the photos provided are for reference purposes, showcasing the colours, patterns, and tones of the sandstone when the paving has been fully installed. These images may depict the sandstone in various conditions, including when wet, dry, or sealed with an enhanced natural stone sealer. Itโ€™s important to note that sandstone appears more vibrant when wet and lighter in pastel tones when dry. Different lighting conditions may also affect images. We offer a sample service, or you can call our expert team on 01329 238150 for further information.

 

Please note that Limestone is a natural material sourced from large quarries. While we strive to give an indication of the tones and colours in each pack, we cannot guarantee the exact quantity or variable of each colour, as this may differ from pack to pack.

 

When the Limestone paving arrives, it may look dusty and pale, with minimal colour variable. It is recommended to unpack the paving and wet it down to reveal the true colour variables. This process will help achieve a random colour effect throughout your patio, avoiding the placement of too many similar tones in one area. Due to its natural composition, you cannot select specific amounts of certain tones; this randomness is a key aspect of the beauty of natural stone.

 

Indian Limestone is slightly porous and will begin to weather naturally once laid, washed, and jointed. Sealing is recommended after a short period to protect the stone and enhance its appearance. Some sealers enrich the colour for a deeper โ€œwetโ€ look, while others maintain a natural, dry finish โ€” the choice depends on your personal preference and desired aesthetic.

 

Natural Indian Limestone Paving: A Comprehensive Overview

Indian Limestone paving is a highly popular choice for patios, garden landscaping and outdoor living spaces due to its contemporary look, refined surface texture and impressive durability. Limestone is a sedimentary stone formed from compacted calcium carbonate deposits over millions of years, resulting in a fine grain structure and colour consistency. Hereโ€™s why limestone is widely chosen across the UK:

1. Aesthetic Appeal

Modern Colours:
Indian Limestone is available in a stylish range of shades โ€” typically Kota Black, Kota Blue, Kota Brown and Tandur (light cream tones). These tonal options make it ideal for modern patios, courtyards and outdoor dining areas.

Smooth, Refined Look:
The crisp edges and naturally flatter surface of limestone create a smart, contemporary finish. Urban garden designers often choose limestone when they want clean lines rather than the more rustic look of sandstone.

2. Durability

Limestone is a strong, dense natural stone that performs exceptionally well outdoors when installed correctly. It handles normal UK weather conditions โ€” sun, rain and frost โ€” but sealing is strongly recommended to help protect colour, especially darker stones such as Kota Black, which can lighten (silver) over time if left unsealed.

โ€“ With correct installation, limestone resists general wear and day-to-day use, making it suitable for most residential patios and walkways.

3. Textured Surface

Limestone paving typically has a riven or lightly textured finish, offering good slip resistance โ€” ideal for UK patios and garden paths.

Honed, brushed or tumbled finishes are also available from many UK suppliers for more premium or contemporary looks.

4. Low Maintenance

Limestone is relatively easy to maintain with periodic cleaning using a neutral pH stone cleaner and warm water. Many homeowners choose to seal limestone after installation to help protect it from fading, moisture and general staining.

Avoid acidic cleaning products โ€” as limestone reacts with acid.

5. Cost-Effective

While limestone paving is more premium than concrete, it is generally better value than stones like porcelain or granite. For many homeowners, it offers the perfect balance of visual quality, longevity and price โ€” especially calibrated 22mm mixed-size patio packs.

6. Eco-Friendly

Limestone is a natural stone requiring low energy consumption during quarrying, making it an environmentally friendly option compared to man-made alternatives. At end of life, it is reusable and recyclable โ€” helping reduce landfill waste.

7. Popular Applications

โ€“ Patios, terraces & garden seating areas
โ€“ Paths & walkways
โ€“ Courtyards & contemporary garden design
โ€“ Steps, lawn edging & landscaping features

The refined surface and colour uniformity mean limestone is especially favoured in modern or minimalist outdoor schemes.

8. Considerations

โ€“ Colour sensitivity: Darker limestone (Kota Black) can gradually lighten if left unsealed.
โ€“ Acid sensitivity: NEVER use acidic cleaners or brick acid.
โ€“ Protective sealing recommended: sealing helps maintain colour & finish.

In summary, Indian Limestone paving is a smart, modern and durable paving option offering stylish colours, refined textures and strong long-term performance when installed and maintained correctly. With the right product choice and sealing routine, it will provide years of enjoyment in your outdoor space.

To ensure your limestone paving project runs smoothly, itโ€™s important to be aware of several considerations when your paving arrives and during installation.

When your paving order arrives, itโ€™s normal for the slabs to appear dusty, pale, or grey. Indian Limestone often has subtle pastel or light tones, which can look muted before cleaning or wetting. This is completely normal. To reveal the true colours and variables, we recommend lightly wetting the slabs before installation. This helps you see the full range of tones, allowing for a more balanced and natural colour palette across your patio, pathway, or terrace.

Each crate of limestone slabs is randomly selected, so the colour distribution may not be even. When ordering multiple pallets, itโ€™s best to take slabs from each pallet during installation to achieve the most consistent effect. Limestone is slightly porous, and over time the colours will deepen and become more vibrant as the stone naturally weathers.

We also recommend ordering all the paving for the same area at the same time, even if installation is staged over several weeks. Natural stone is unique and not batch-coded, so any paving purchased later may come from a different quarry section, resulting in noticeable colour variable. If you are adding to an existing limestone patio, please contact our team and provide images; we can help identify a suitable match.

For installation, applying a priming slurry, SBR, or both to the back of the slabs is highly recommended. This creates a barrier to reduce moisture absorption, helping prevent efflorescence and minimise staining from the base. Applying a priming slurry across the underside of the slab also improves adhesion to the base, ensuring full contact and reducing the risk of mirror staining (white marks on the surface), which can be difficult to remove.

Investing in quality tools is essential. Ensure the correct blades are used and that your disc cutter is suitable and powerful enough for cutting natural stone.

Jointing your patio can be simplified using an all-weather brush-in jointing compound, which provides stability comparable to traditional sand and cement. Be aware that very dark jointing compounds may leave minor stains on the edges of lighter-coloured limestone.

Avoid using any acid-based cleaners on limestone to remove residue, as this can damage the stone.

We recommend thoroughly jet washing your paving after installation, before jointing. After jointing has cured, a second jet wash will help clean and enhance the finished surface.

Sealing is advised for Indian Limestone. Options include natural finish sealers, which preserve the original look, or colour enhancers, which bring out the stoneโ€™s tones and give a damp-look finish. Always follow the manufacturerโ€™s instructions. Do not use non-breathable sealers (e.g., resin or varnish) within the first six months; instead, use a breathable stone sealer to allow minerals and salts to naturally weather and escape from the stone.

Indian Limestone Paving โ€“ Care & Maintenance Guidance

Laying a limestone patio can be messy, so itโ€™s important to take precautions during installation to prevent staining. Use protective sheeting and boards where possible. If any residue appears on the slabs during installation, clean it immediately. Substances like wet cement, mortar, or adhesive can penetrate the stone and become very difficult to remove once dry. Avoid using acid-based products, as these can damage the limestone surface.

Porosity and staining:
Indian Limestone is naturally porous and can absorb liquids from its surface. Wet leaves, bird droppings, moss, and other organic material can cause staining. Once these substances penetrate the stone, removing stains can be challenging.

Sealing:
Sealing your limestone paving helps protect against stains, excess moisture, frost damage, and the growth of moss, mould, and algae. It is recommended to seal your paving approximately 12 weeks after installation, allowing the stone to fully dry. If sealing is required earlier (within six to nine months), always use a breathable natural stone sealer to allow minerals and salts to escape naturally. Black Limestone in its natural form will be a charcoal/grey colour if left untreated. This will lighten further when exposed to UV sunlight which will bleach the natural pigment in the stone. To ensure Limestone retains its newly quarried darker tones, you need to seal the surface – for best results, use a dar stone sealer which will turn the stone black (as if they are wet)

Efflorescence:
During the drying process, you may notice a white or light grey powdery substance on the surface of the limestone, known as efflorescence. This is caused by natural salts and minerals coming to the surface, particularly in damp or humid conditions. Although it may appear unsightly, efflorescence does not affect the structural integrity of the stone and usually resolves within the first three to six months.

Ongoing maintenance:
Indian Limestone requires periodic maintenance to keep it looking its best. Use natural stone cleaners and black spot removers to prolong the life and appearance of your patio. Over time, you may also need to refresh the joints by grinding out and redoing the jointing to maintain a clean, level finish.
