Granite’s adaptability is defined by the science of its surface treatment and how it interacts with light, friction, and the environment. The finish determines reflection, grip, and resistance—affecting how the stone functions in different conditions while shaping its visual character.

At Aravali India Marbles & Granites, a top granite supplier and exporter from India, every finish is crafted using advanced technology to meet ASTM and EN dimensional stone standards. 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

Polished granite has a mirror-smooth surface created through fine mechanical abrasion and high-grit polishing. 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

Honed granite provides a matte or satin finish with minimal reflection while maintaining color uniformity.

Rough Granite Texture Built for Weather Resistance


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

This finish offers R11–R12 slip resistance and high resistance to weathering, moisture, and UV exposure.

Leathered Granite – Textured Luxury for Modern Interiors


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

The brushing process partially seals pores, improving stain resistance and ease of cleaning.

Industrial-Grade Granite Finish for Outdoor Safety


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

Bush-hammered granite has a coarse, pitted texture created by controlled mechanical impact.

Fine-Grain Matte Granite for Consistent Aesthetics


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

The finish provides excellent UV stability and is frequently used in engraved or etched applications.

Shot-Blasted Granite – High-Performance Texture for Heavy Traffic Areas


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

It ensures consistent texture and enhances coating adhesion, making it ideal granite finishes guide for advanced architectural and composite material applications.

Rock-Faced Finish – Classic Edge for Heritage & Rustic Designs


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

Rock-faced granite, also known as split-face, offers a rugged, natural appearance achieved through chiseling.

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

Lappato or semi-polished granite features a mix of matte and glossy sections, creating a balanced interplay of light and texture.

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 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.

Final Thoughts – Where Science Meets Stone Design


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

By combining material science, finishing technology, and architectural understanding, Aravali delivers stone surfaces that perform and inspire.
