Comprehensive Technical Guide to Granite Surface Finishes: Design, Texture & Performance
Granite’s adaptability is defined by the science of its surface treatment and how it interacts with light, friction, and the environment. 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
This finish enhances color depth, clarity, and visual brilliance, giving the stone a luxurious appearance. 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.
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.
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.
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.
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, sandblasted granite finish monuments, memorials, public installations
The finish provides excellent UV stability and is frequently used in engraved or etched applications.
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.
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
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
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
It offers moderate slip resistance with elegant shine, making it suitable for hotels, lobbies, and contemporary interiors.
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.
