Considerations To Know About granite surface textures
A Complete Engineering Overview of Granite Surface Finishes and Their Applications
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.
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 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.
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
It reduces glare and is perfect for modern interiors that emphasize understated sophistication.
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
This finish offers R11–R12 slip resistance and high resistance to weathering, moisture, and UV exposure.
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
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
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
Sandblasted granite creates a soft, even texture with low reflection and consistent grain.
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
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 sandblasted granite finish
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 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
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
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.
Conclusion: Precision Finishing, Engineered Aesthetics
A granite finish determines more than just its look—it defines performance, longevity, and compatibility with the intended environment.
By combining material science, finishing technology, and architectural understanding, Aravali delivers stone surfaces that perform and inspire.
Whether it’s a mirror-polished granite for luxury interiors or a flamed finish for exterior resilience, Aravali’s finishes are designed to endure, impress, and elevate every architectural vision.
