How granite surface finishes can Save You Time and Help you Get to Know More About It.
A Technical Guide to Granite Surface Finishes: Engineering Texture and Performance
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.
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.
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.
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
Honed granite provides a matte or satin finish with minimal reflection while maintaining color uniformity.
Flamed Granite – Non-Slip Surface for Outdoor Use
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.
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
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 Finish – Mechanically Indented for Slip Resistance
Technical Characteristics:
Surface Roughness (Ra): 20–50 µm
Processing: Pneumatic hammering using multi-point carbide tips
Applications: Exterior paving, stair treads, plazas, industrial flooring
This finish is best suited for outdoor flooring, ramps, and industrial walkways exposed to moisture or heavy use.
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, 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: granite surface finishes 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.
Waterjet Granite – Clean Surface Engineering for Façades
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
It retains structural strength while adding a raw, natural aesthetic to buildings, commonly used in heritage restorations and rustic-style architecture.
Lappato Granite – Semi-Gloss Surface with Dual Texture
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.
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.
