The performance and beauty of granite depend on the way its surface is processed and finished. Each finish gives granite unique optical and mechanical properties that make it suitable for specific architectural needs.

Aravali India Marbles & Granites applies precision finishing processes aligned with global quality norms to achieve durable, functional, and aesthetic results. Whether it’s a high-gloss interior surface or a non-slip exterior texture, every finish is designed to enhance strength, safety, and beauty.

Polished Granite – Mirror-Like Surface with Enhanced Strength


Technical Characteristics:
Surface Roughness (Ra): ? 0.2 µm
Gloss Level: > 90 GU
Processing: Multi-stage diamond abrasive polishing up to 12,000 grit
Applications: Interior flooring, countertops, wall cladding, reception areas

It also compacts the crystalline structure, increasing surface density and reducing porosity. Ideal for indoor environments, polished granite combines elegance with easy maintenance and stain resistance.

Matte Granite Surface for Contemporary Designs


Technical Characteristics:
Surface Roughness (Ra): 1–3 µm
Gloss Level: 20–40 GU
Processing: Medium-grit progressive polishing without final buffing
Applications: Commercial flooring, wall cladding, stairs, corridors, bathrooms

It reduces glare and is perfect for modern interiors that emphasize understated sophistication.

Flamed Granite – Non-Slip Surface for Outdoor Use


Technical Characteristics:
Surface Roughness (Ra): 15–30 µm
Gloss Level: < 5 GU
Processing: Oxy-acetylene flame heating (~1350°C) followed by quenching
Applications: Outdoor paving, exterior cladding, pool decks, walkways

Flamed granite is produced by subjecting the surface to high heat, causing differential mineral expansion that results in a rough, anti-slip texture.

Leathered Granite Finish – Tactile Depth with Low Sheen


Technical Characteristics:
Surface Roughness (Ra): 5–10 µm
Gloss Level: 10–20 GU
Processing: Brushed with diamond abrasives after honing
Applications: Countertops, vanity tops, accent walls, outdoor furniture

Leathered or brushed granite offers a tactile finish that highlights the stone’s mineral patterns with a soft, textured feel.

Bush-Hammered Granite – Heavy-Duty Finish for Grip and Durability


Technical Characteristics:
Surface Roughness (Ra): 20–50 µm
Processing: Pneumatic hammering using multi-point carbide tips
Applications: Exterior paving, stair treads, plazas, industrial flooring

The resulting surface offers exceptional slip resistance with a CoF greater than 0.7, meeting global anti-slip standards.

Sandblasted Granite – Subtle Finish for Modern Architecture


Technical Characteristics:
Surface Roughness (Ra): 10–20 µm
Processing: Impact of silica or steel grit under compressed air
Applications: Façades, monuments, memorials, public installations

It enhances slip resistance and diffuses light evenly, making it suitable for large surfaces like building exteriors, monuments, and memorial plaques.

Shot-Blasted Granite Finish – Industrial Durability and Grip


Technical Characteristics:
Surface Roughness (Ra): 15–25 µm
Processing: Steel shot blasting for uniform abrasion
Applications: Driveways, ramps, transport terminals, high-traffic pathways

This finish is ideal for industrial zones, parking areas, and external pavements exposed to constant friction and impact.

Waterjet Granite – Clean Surface Engineering for Façades


Technical Characteristics:
Surface Roughness (Ra): Adjustable 5–25 µm
Processing: High-pressure water erosion for surface texturing
Applications: Designer façades, custom textures, architectural panels

The waterjet or hydro finish uses high-pressure water to create digitally controlled surface patterns without heat or mechanical stress.

Rock-Faced Granite Finish – Natural Edge, Structural Expression


Technical Characteristics:
Surface Roughness (Ra): Variable (25–60 µm)
Processing: Manual or mechanical chiseling of edges
Applications: Boundary walls, façades, retaining walls, rustic exteriors

It retains structural strength while adding a raw, natural aesthetic to buildings, commonly used in heritage restorations and rustic-style architecture.

Lappato (Semi-Polished) Granite Finish – Hybrid Gloss for Modern Interiors


Technical Characteristics:
Surface Roughness (Ra): 0.5–2 µm
Gloss Level: 40–70 GU
Processing: Partial polishing of raised areas with fine abrasives
Applications: Indoor flooring, wall cladding, commercial lobbies

It offers moderate slip resistance with elegant shine, making it suitable for hotels, lobbies, and contemporary interiors.

Choosing the Right Finish: A Functional Perspective



For Indoor Flooring: Choose Polished or Honed finishes for smooth texture, visual brilliance, and ease of maintenance.

For Outdoor Paving: Opt for Flamed leathered granite finish or Bush-Hammered finishes that offer superior slip resistance and weather durability.

For Countertops: Use Polished or Leathered granite for stain resistance, low porosity, and a refined aesthetic.

For Façades and Cladding: Select Sandblasted, Flamed, or Waterjet finishes for UV resistance, visual uniformity, and long-term strength.

For Industrial Flooring: Go with Bush-Hammered or Shot-Blasted finishes for high friction, wear resistance, and load endurance.

Conclusion – The Art and Engineering of Granite Finishes


A granite finish determines more than just its look—it defines performance, longevity, and compatibility with the intended environment.

At Aravali India Marbles & Granites, each slab is processed with scientific accuracy and creative craftsmanship.

Whether it’s a mirror-polished granite for luxury interiors or a flamed finish for exterior resilience, Aravali’s finishes are designed to endure, impress, and elevate every architectural vision.
