A Complete Engineering Overview of Granite Surface Finishes and Their Applications
The performance and beauty of granite depend on the way its surface is processed and finished. The finish determines reflection, grip, and resistance—affecting how the stone functions in different conditions while shaping its visual character.
Each granite surface from Aravali India Marbles & Granites is engineered for both design appeal and long-term performance. Whether it’s a high-gloss interior surface or a non-slip exterior texture, every finish is designed to enhance strength, safety, and beauty.
High-Gloss Polished Granite for Elegant Interiors
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
This finish offers R11–R12 slip resistance and high resistance to weathering, moisture, and UV exposure.
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
The brushing process partially seals pores, improving stain resistance and ease of cleaning.
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
Bush-hammered granite has a coarse, pitted texture created by controlled mechanical impact.
Sandblasted Granite Finish – Fine Texture with Matte Uniformity
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 – 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
Shot blasting gives granite a slightly rougher and more uniform texture than sandblasting, resulting in high slip resistance and superior durability.
Waterjet Finish – Precision Texture for Modern Architecture
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.
Split-Face Granite – Raw Texture for Architectural Strength
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.
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
It offers moderate slip resistance with elegant shine, making it suitable granite finishes guide for hotels, lobbies, and contemporary interiors.
Granite Finish Selection Based on Function and Location
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.
