Please carefully review this guide, which provides essential product information for Bluestone’s DIORE Terrazzo surfaces, along with key recommendations for aftercare and maintenance. Following these guidelines is crucial to prevent damage or deterioration, as Bluestone cannot be held responsible for issues arising from improper care.
Diore Terrazzo is a premium, durable surface known for its aesthetic appeal and strength. However, like all materials, Terrazzo has certain inherent characteristics that should be considered. Both cement and resin Diore Terrazzo may exhibit natural flaws, such as pinholes or hairline cracks, which can be minimized but not completely eliminated. If extreme durability and resistance to stains are your top priorities, you may want to explore alternative materials, such as quartz or granite, which offer similar looks with fewer vulnerabilities.
Potential Issues
Pinholes
Pinholes are small air pockets that may develop during the manufacturing process, often becoming noticeable after the Diore Terrazzo is ground. These can typically be filled through grouting, but a few may remain visible.
Cracks, Scratches, and Chips
While Diore Terrazzo is durable, it can still crack or chip if mishandled. To mitigate this risk, rounded or chamfered edges are recommended. Be cautious when handling heavy objects like cast iron cookware, as dropping such items can cause significant damage. Additionally, extra care should be taken around cutouts (such as for kitchen sinks or hobs), as these areas are more prone to chipping and cracking. Structural movement can also cause cracking, particularly if the base beneath the Diore Terrazzo is unstable or cannot support the required weight (55kg/m² for cement Diore Terrazzo, 50kg/m² for resin Terrazzo).
For some Terrazzos, particularly those with larger chippings, hairline cracks can appear during the production process (see images above). Some of these are visible, while others are not. These do not affect the integrity or strength of the material in general and are caused by the way the resin or cement sets around the larger chippings. This is a characteristic of Terrazzo and not a product failure.
Variations
Due to natural and manufacturing processes, slight variations in color and pattern may occur in Diore Terrazzo. It is recommended to view the material in person prior to placing your order, as Bluestone cannot be held responsible for variations after the slabs are cut or installed.
Common Issues
Scuffs and Scratches
Scuffs, especially in high-traffic areas, are usually superficial and can be removed with regular cleaning. However, deeper scratches may require professional re-grinding and polishing to restore the surface.
Stains
Diore Terrazzo is a porous material, making it susceptible to staining from acidic substances or products such as red wine, vinegar, or sauces. To avoid permanent damage, spills should be cleaned immediately using a neutral detergent (e.g., dishwashing soap). Bluestone’s Anti-Stain Protection offers added protection against stains, but we recommend reapplying it every 6 to 12 months to maintain effectiveness.
Special Cleaning
For more severe stains or neglected surfaces, re-grouting and re-polishing may be necessary to restore Diore Terrazzo. It is recommended that special cleaning and restoration be carried out by professionals, as improper methods can cause additional damage.
Maintenance Top Tips
- Apply Bluestone’s Anti-Stain Protection every 6 to 12 months to protect against stains.
- Wipe spills immediately and clean the surface daily.
- Use neutral cleaners, such as dishwashing liquid, and avoid products containing bleach or vinegar.
- Prevent liquids from pooling on the surface to avoid stains.
- Do not place heavy objects directly on the surface, and avoid sitting on the countertop to prevent cracking or chipping, especially near cutouts for appliances.
By following these care and maintenance tips, your Diore Terrazzo surface will maintain its beauty and durability for many years to come. If you have any questions or need further assistance, please don’t hesitate to contact Bluestone’s team for expert advice and support.

Edge DETAILS
Enhance the finish of your porcelain worktop with our precision-crafted edge profiles. Designed to complement both modern and traditional interiors, our edge details add a stylish look while maintaining the durability and hygiene benefits.
Each edge is expertly fabricated to ensure a smooth, long-lasting finish.



Return End Styles
Return ends are custom-shaped finishes applied to the exposed edges of the worktop. They’re designed to provide a polished, continuous look where the surface terminates—whether against a wall, cabinet, or open space.
Each return style serves a specific purpose, from creating standout design features to accommodating architectural details or practical use cases. Whether you're planning a flowing curved end, a distinctive break front, or precision notching for cabinetry, these return styles ensure a tailored, high-quality finish.
Explore the full range below to find the perfect return style for your project.












Upstands
Upstands are an essential element for achieving a refined and practical finish where your worktop meets the wall, offering protection against splashes and spills while creating a seamless transition between horizontal and vertical planes. Square upstands provide a sharp, modern look with a defined 90° junction, and are fixed on-site using special glue or silicone. Fabricated to exacting standards to ensure a good match with your worktop. However, it’s important to note that upstands are made in a straight line, and any imperfections or large variations in the wall profile can leave gaps, which will need to be filled with decorators’ caulk. To achieve the best result, plastering or tiling should be completed after the worktops have been installed, ensuring a polished, professional finish.

Cutouts & Drainer Grooves
Custom cutouts and drainer grooves add both functionality and finesse to your solid surface worktop. Whether you're integrating sinks, hobs, tap holes, or pop-up sockets, each cutout is precisely machined to suit your specifications and seamlessly finished to match the surrounding surface.
Drainer grooves can be added for both style and practicality—angled or flat, they channel water efficiently back into the sink while enhancing the clean, bespoke look of your kitchen or utility space. Every detail is carefully crafted to maintain the durability, hygiene, and elegance of your worktop.

Technical Information
Overhangs and End Panels
Terrazzo Worktops must be supported every 600mm.
Maximum recommended overhang is 300mm. Greater than 300mm requires steel support.
Solid underside wrapping is recommended on overhangs or end panels when MDF substrate is visible beneath.
Due to the weight of Terrazzo worktops, it is essential that your units are level and securely fixed.
Sinks
Because Terrazzo worktops are fabricated to give a seamless appearance, it is also possible to install sinks and bowls from the same materials for a smooth and elegant finish.
A minimum of 70mm is required between sink cut-outs.
If a waste disposal unit is fitted to an undermounted sink after installation, additional support will be required, otherwise your warranty may be invalidated.
Hobs and Splashbacks
Splash backs or wall cladding are installed with a minimum 50mm gap behind an electric hob and a minimum 100mm gap behind a gas hob. There must also be a minimum 50mm gap from the cutout to the front of the worktop. To accommodate these requirements, it is sometimes necessary to widen the worktop to what is called a “breakfront.”
- Sink cutouts are placed a minimum 50mm from the worktop front edge
- A minimum of 120mm is required between two hob cutouts
- A minimum of 100mm is required between hob and sink cutouts
- A minimum of 70mm is required between two sink cutouts
- If a waste disposal unit is fitted to an undermounted sink after installation, additional support will be required, otherwise your warranty may be invalidated
