Surface Finishes

When people use stone for various covering applications in the interior or exterior area of the building, the stone needs to have finish on its surface. A finish on natural stone not only prevents damage or contamination from bacteria, it also uncovers the natural beauty of the stone for all to see. Different surface finishes can also lend significantly different textures to the stone and even change the perceived of the stone. Here are the descriptions of the surface finishes commonly used in stone industry.

POLISHED:

A polished finish is a smooth, high-gloss finish, attained by machine processing the stone surface through a series of buffing techniques.

HONED:

A finish with the look and feel of satin is attained by machine processing the stone surface through a series of buffing techniques that stop short of the final, high-polish stage that creates a Polished Finish. A Honed surface provides a flat, matte or satin finish creating a more informal and softer look than Polished. A honed finish shows fewer scratches, and requires very little maintenance.

LEATHER:

Leather finish begins with a honed surface that is then worked with diamond brushes; this process enhances the color and closes pores, making the stone denser. Leathering has a nice sheen and is less porous than a Honed finish.

BRUSHED/ANTIQUED:

This is a finish with the look of satin, and gracefully rippling surface texture. The Brushed/Antiqued finish features a worn-down look achieved by machine brushing the surface of the stone, simulating natural wear over time. Finally, sandblasting gives any project natural depth and contrast, without changing stone colors.

FLAMED:

A finish that is rougher to the touch with a granular feel. A flamed finish is achieved by heating the surface of the stone to extreme temperatures, followed by rapid cooling. The stone’s surface will pop and chip leaving a rough, unrefined texture. This process is usually done with granite material. Flamed granite has a highly textured surface, making it ideal for areas where slip resistance might be a concern such as shower areas, exterior/interior walkways, and stairs.

NATURAL CLEFT:

Slate is created as layer upon layer of silt particles are deposited on a lake bottom, creating a layered structure referred to as “clefted”. This “clefting” gives a three dimensional texture to the slate and its durability depends on the degree of metamorphosis (heat and pressure) it is exposed to. The denser and harder the slate, the less prone it is to “spalling” or flaking of the surface material.

NATURAL STONE EXTRACTION:

If a natural look is needed in block format, Alliance Minerals can maintain the natural look of the extracted block without finishing any of the stone. For example a stone bathtub may need polishing for the bathing area, but the exterior portion of the vessel can maintain its natural look.

JAGGED:

It is a soft, textured finish that emanates the beauty and elegance of an antique object. The beauty of its deep sheen makes it suitable for interior & exterior cladding, flooring, table and bathroom tops.

FINE RUBBED:

It is a soft to touch finish, ideal for flooring, cladding, table and bathroom tops. Its smooth surface without any reflection offers non-slippery surface with enhanced colors.

RUSTIC:

Its rustic surface with an irregular pitted finish results in a unique look that’s a fine mix of the contemporary and the traditional. Its non-slippery surface makes it perfect for stairs, wet areas and exterior paving.

RIVEN:

Riven finish is achieved by natural splitting of Phyllite along well-defined cleavage. This gives the surface a rich, unique texture. Riven finish makes the surface non-slippery, hence, is suitable for exterior cladding, paving and roofing.
