Some Easy Facts About types of granite finishes Described
Granite Surface Finishes Explained – Engineering Texture, Strength & Visual Appeal
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.
At Aravali India Marbles & Granites, a top granite supplier and exporter from India, every finish is crafted using advanced technology to meet ASTM and EN dimensional stone standards. 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.
Honed Granite – Satin Smooth Finish with Subtle Appeal
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 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
Flamed granite is produced by subjecting the surface to high heat, causing differential mineral expansion that results in a rough, anti-slip texture.
Soft-Touch Granite Surface with Warm Appeal
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, 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 flamed granite finish
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
It ensures consistent texture and enhances coating adhesion, making it ideal for advanced architectural and composite material applications.
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.
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.
