About Astrix Polished Granite Slab
Astrix Polished Granite Slab Random presents black granite in a rectangular slab format. Its polished surface brings a refined finish to the natural stone material, while the straight-cut edge gives the slab a clean, direct profile. Offered in a random size and 1 1/4 thickness, this slab provides a substantial format for tailored surface applications.
The deep black color of Astrix granite can support a range of design directions, from classic interiors to modern and rustic settings. The polished finish emphasizes the stone’s finished surface and creates a composed, architectural appearance suitable for spaces where a darker material palette is desired.
This granite slab is listed for residential countertops, allowing the material to become a central surface within a kitchen or other residential interior setting. Its rectangular format offers flexibility for projects that call for slab-based fabrication and a continuous stone presentation.
Astrix Polished Granite Slab Random is also specified for residential interior walls, commercial interior walls, and shower walls. Used vertically, the black granite can introduce visual depth and a polished stone finish across feature walls and other interior wall applications.
As part of the Granite Slabs collection, this product combines black granite, a polished finish, and a straight-cut edge in a random slab size. It is an option for bathroom and kitchen projects seeking a classic, modern, or rustic material expression.
At Marble Systems, we pride ourselves on offering the highest-quality natural stone slabs, including marble, limestone, quartzite, and travertine. To ensure the beauty and durability of your stone investment, proper installation and ongoing maintenance are essential. Please review the following guidelines before handling or installing any Marble Systems slabs.
1. Slab Inspection & Fabrication
- All slabs must be inspected upon delivery for color variation, veining, structural soundness, and finish quality.
- Any cracks, fissures, or natural features should be reviewed with your fabricator prior to cutting.
- The final layout, cutting, and installation of the countertop or stone application must be determined by a licensed and experienced stone fabricator.
- Bookmatching and vein alignment must be planned prior to fabrication.
2. Installation Guidelines
- All substrates must be level, structurally sound, and properly reinforced for the weight of natural stone.
- Use appropriate backer boards, supports, and adhesive systems recommended for natural stone slabs.
- Expansion joints should be incorporated where applicable.
- Ensure all cutouts (sinks, cooktops, etc.) are properly supported.
- Avoid dragging heavy equipment or materials across the slab surface during install.
3. Sealing & Surface Protection
- All natural stone slabs must be sealed prior to or immediately after installation with a high-quality penetrating sealer appropriate for the stone type.
- Resealing should be performed every 6–12 months, depending on usage and exposure to moisture or staining agents.
- Acidic substances (e.g., citrus juice, vinegar) can etch marble and limestone. Clean spills promptly.
4. Sealing & Surface Protection
- Use pH-neutral, stone-safe cleaners only.
- Avoid abrasive scrubbers or harsh chemicals.
- Use coasters, trivets, and cutting boards to preserve the surface.
- Wipe down countertops daily with a soft cloth or sponge.
5. Disclaimer
- Natural stone is a product of nature and may feature inherent color and texture variations.
- Marble Systems is not responsible for wear and tear, etching, or staining on finished stone slabs once installed.
- All final fabrication, handling, and installation decisions must be made by a qualified stone professional or licensed fabricator.
