A Complete Engineering Overview of Granite Surface Finishes and Their Applications
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.
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.
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.
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
It is ideal for exterior flooring, landscaping, and facade applications where safety and durability are essential.
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.
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
The resulting surface offers exceptional slip resistance with a CoF greater than 0.7, meeting global anti-slip standards.
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
This finish is ideal for industrial zones, parking areas, and external pavements exposed to constant friction and impact.
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.
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
It retains structural strength while adding a raw, natural aesthetic to buildings, commonly used in heritage restorations and rustic-style architecture.
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.
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.
