Comprehensive Technical Guide to Granite Surface Finishes: Design, Texture & Performance
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
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
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
It is ideal for exterior flooring, landscaping, and facade applications where safety and durability are essential.
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
This surface provides a natural look with low sheen and high grip, making it popular in kitchens, bathrooms, and semi-exterior spaces.
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, types of granite finishes 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
Sandblasted granite creates a soft, even texture with low reflection and consistent grain.
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
Shot blasting gives granite a slightly rougher and more uniform texture than sandblasting, resulting in high slip resistance and superior durability.
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 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
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.
How to Choose the Right Granite Finish
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.
