ASH GREY / KURNOOL GREY LIMESTONE
Overview
Ash Grey Limestone, also known as Kurnool Grey Limestone, is a natural South Indian limestone valued for its consistent grey tone, durability, and versatile applications.

Custom Sizes
If standard sizes don’t meet your requirement, the stone can be cut to any width, length, or thickness. Raw blocks from quarries are processed into slabs, tiles, walling stones, kerbs, and cobbles based on client specifications.
Formation & Natural Variation
This limestone is a sedimentary rock formed over millions of years in naturally created layers (10–50 mm thick). Because it is a natural product, no two pieces are exactly alike. Occasional white rounded mineral spots may appear — this is normal and not considered a defect.
Available Finishes
Honed finish
Satin finish
Lapota finish
Leather finish
Bush-hammer finish
Each finish brings a different texture and visual effect, suitable for modern, rustic, or traditional design styles.
Leather Finish
An antique, tumbled appearance similar to aged stone naturally worn by foot traffic. Non-slippery and ideal for pavements, pathways, and indoor flooring.
Lapota Finish
Machine-cut edges with a weathered surface, giving a vintage, aged look. Excellent for homes, villas, hotels, and outdoor paving.
Bush-Hammered Finish
Created by high-impact hammer tooling, forming uniform pits and a rugged, slip-resistant texture. Ideal for wet areas and outdoor walkways.
Laying Instructions
Always apply a high-quality sealant before and after installation.
Sealing reduces porosity, prevents stains, and improves slip resistance.
Stones can be re-finished during their lifetime to restore appearance.
Use professional layers for precise leveling and alignment.
Do not use acid-based cleaners — they can damage the stone.
