SURFACE-FINISHES
(All images of French Brown)
1. Polished |
|
 |
A glossy surface finish which is very smooth and not very porous. The shine comes from the natural reflection of the stone's crystals. Polishing bricks and powders used during fabrication help draw out the natural reflection of the stone's crystals (prisms) to create vibrant colors and grains of natural stone. Therefore, the shine is not provided by coating. |
2. Flamed Finish |
|
 |
A flamed finish is created using an extremely hot flame. The heat stresses the material causing crystals to pop out. Flaming creates a very rough texture best used for exterior purposes. A flamed finish is excellent for exterior walkways. Flaming can only be done on granites. |
3. Honed Finish |
|
 |
Honing a polished material opens up the pore making it more susceptible to staining than the same material in a polished finish Honing will "grey out" or fade the color of the stone, this is more noticeable on darker materials than on lighter materials. Provides a flat to low sheen gloss. This finish is very smooth, but often very porous. Honed stone colors are not as vibrant as a polished stone. This finish is often used for high traffic buildings. |
4. River-Washed Finish |
|||||||||
 |
This finish is the pre-cursor to the leather finish. Before a slab can be river washed it must first be flamed. The river washing process simply smooths out the roughness of the flamed finish. River washed surfaces are good for interior or decorative use. |

5. Leather Finish |
|
 |
A leathered finish is a newer style of finishing granite that has become increasingly popular in recent years. The density (or depth) of its’ texture will vary depending on the type and composition of the stone, an act of mother nature which gives each material a unique color and appearance. The leathered finish out stands the honed by giving a more sophisticated look to the stone. The leathering process closes the stone pores which helps it to become more stain resistant than the honed surface. |
6. Lappato Finish |
|
 |
The Lappato finish exalts the “time-worn” impression and timeless beauty of natural stone satisfying the most demanding performances. The lappato surface softly reflects the light to reflect its discreet structure, and finely chamfered edges give the granite a special elegance. The light polishing is carried out the same way as polished version, but the brushing is very light or just on the peaks of the tile surface to create the shiny-rough look. |
7. Bush-Hammered Finish |
|||||||||
 |
Another textured finish. This is best for external use. Bush hammering will "grey out" or fade the color of the stone to an even greater extent than honing. This finish is rougher than leathering and more uniform. This finish can be done to virtually any stone. |
||||||||
8. Sand-Blasted Finish |
|||||||||
 |
This textured surface can vary (like leathering) based on the composition of the stone being blasted. Blasting will also "grey out" or fade the color (even more so than honing). A blasted surface is extremely porous and will be very hard to keep clean. |

Quality Control Criteria
Polishing |
Polishing will be uniform throughout the slabs/tiles and in gloss meter as: Flaming Flaming will be uniform throughout the slabs/tiles and brushed evenly on slabs after flaming. Thickness +/- 1.0mm in tolerance for slabs ; +/- 0.5mm in tolerance for tiles DIAGONAL OUT +/- 0.1mm in tolerance for tiles. |
