| Product Specifications | |
|---|---|
| General | |
| Product Name | Kandla Grey Sandstone – Honed Hearth Grade |
| Material Type | Natural sandstone |
| Category | Fire hearth slab / fireplace stone |
| Country of Origin | India |
| Thickness Options | 30mm |
| Colour Description | Soft to mid grey with smooth tonal movement, appearing slightly deeper when sealed. |
| Surface Finish | Machine-honed, smooth and flat with a matte low-sheen finish. |
| Natural Variation | Low–medium variation in tone and shading; honing softens the natural surface texture, but subtle grain and colour shifts remain visible. |
| Edge Finishing Notes | All edges are precision machine-cut and hand-sanded where needed. Slight tonal variation, small sanding marks or tiny micro-chips may be visible and are typical of honed sandstone. |
| Weight | Approx. 70–120 kg per m² depending on thickness. |
| Density | Approx. 2,300–2,400 kg per m³. |
| Technical Characteristics | |
| Heat Absorption / Retention | High thermal mass, excellent heat absorption and steady heat release. |
| Maximum Temperature Resistance | Typically performs safely up to approx. 300–400 °C before risk of thermal shock. Must not be in direct contact with open flame. |
| Compressive Strength | Approx. 80–120 MPa. |
| Flexural Strength | Approx. 7–12 MPa. |
| Porosity | Medium–high (honed surfaces may mark more easily if unsealed). |
| Water Absorption | Approx. 1–3%. |
| Thermal Conductivity | Approx. 2.0–3.0 W/mK. |
| Chemical Sensitivity | Resistant to mild household acids, but strong acids or aggressive cleaners may cause etching or colour lightening. |
| Stain Resistance | Moderate; sealing is strongly recommended to reduce marking. |
| Salt Sensitivity | Slight to moderate, typical of natural sandstone. |
| Natural Characteristics of Sandstone | |
| General Nature of the Stone | Kandla Grey Sandstone is a natural sedimentary stone formed over millions of years. Natural variation in tone, grain and surface features is expected and is not considered a defect. |
| Colour & Tonal Variation | The stone ranges from light to mid grey with naturally soft transitions. Honing slightly deepens the colour and gives a more uniform appearance, though natural movement remains visible. |
| Surface Texture & Grain | Honing removes the natural riven relief to produce a smoother, flatter surface, but subtle grain lines, faint layering and light variations in texture may still be visible. |
| White / Pale Mineral Patches | Occasional pale bands, soft clouding or mineral patches may appear due to natural variation in sandstone composition. These are not considered faults. |
| Rust / Iron Spotting | Kandla Grey Sandstone may show iron oxidation over time, resulting in orange or brown rust-like spots or halos. This is a natural process caused by iron minerals within the stone. |
| Production Enhancements | Where needed, epoxy filler, localised smoothing or colour-enhancing treatments may be applied to refine the surface. These do not indicate lower-grade material and are common with honed stone. |
| Application & Packaging | |
| Suitable For | Fire hearths, stove bases, fireplace surrounds, chamber floors, inglenooks and internal stone features. |
| Application | Fire hearth. |
| Sealing | Sealing is strongly recommended to reduce marking and improve stain resistance, especially on a honed surface. |
| Installation Notes | Install on a level, load-bearing substrate. Allow expansion gaps for temperature change. Keep away from open flame. Use adhesives and sealers suitable for natural stone. |
| Packaging | Supplied on wooden pallets or crates with protective layers. |
| Availability | Available in cut-to-size and various standard hearth sizes, subject to stock. |
