Comprehensive Technical Guide to Granite Surface Finishes: Design, Texture & Performance
In both commercial and residential construction, granite’s versatility lies not only in its mineral composition but in the precision engineering of its surface finish. 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 Finish – High Reflectivity, Maximum Density
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.
Honed Granite Finish – Smooth, Non-Reflective Elegance
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.
Flamed Granite Finish – Thermally Textured for Exterior Durability
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
It is ideal for exterior flooring, landscaping, and facade applications where safety and durability are essential.
Soft-Touch Granite Surface with Warm Appeal
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 Finish – Mechanically Indented for Slip Resistance
Technical Characteristics:
Surface Roughness (Ra): 20–50 µm
Processing: Pneumatic hammering using multi-point carbide tips
Applications: Exterior paving, types of granite finishes stair treads, plazas, industrial flooring
Bush-hammered granite has a coarse, pitted texture created by controlled mechanical impact.
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.
Toughened Granite Surface for Outdoor & Industrial Spaces
Technical Characteristics:
Surface Roughness (Ra): 15–25 µm
Processing: Steel shot blasting for uniform abrasion
Applications: Driveways, ramps, transport terminals, high-traffic pathways
Shot blasting gives granite a slightly rougher and more uniform texture than sandblasting, resulting in high slip resistance and superior durability.
Hydro-Finished Granite – Digitally Controlled Texture Design
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 for advanced architectural and composite material applications.
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.
Semi-Polished Granite Finish Combining Shine and Grip
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.
