FINISHES
The different techniques and mechanical treatments applied allow us to provide our clients with a wide variety of finished, therefore multiplying use possibilities.
Honed
a surface soft, totally smooth e flat, that shows the true coloring of the materials without the shine and the detailing of the polished finish. The honed finish is very cosy and comfortable..
Flamed
Produced by exposing the stone to high temperatures, it should be noted that not all materials blaze. The flamed finish is flat enough for paving, although it admits variations in the relief of its surface and presents a face composed of layers or “chips”.
POLISHED
a surface bright that enhances the complete coloring of materials, as well as its specific characteristics (the grain, the shafts, etc). Completely flat and smooth, this finish conveys feelings of nobility and refinement and reveals all the beauty and strength of natural stone.
SHOTBLASTED
The sandblasted finish is anti-slippery and especially suitable for outdoor floors and walls. Of rough surface, The blasted material is sufficiently flat and used for paving.
SANDBLASTED
The sandblasting finish is anti-slippery, e semi-rough, sufficiently flat and well suited for paving. comparatively, this finish is less rough than the blasted and rougher to the touch than the brushed.
NATURAL CLEFT/SPLIT FACE
Finish appearance 100% natural obtained through cleavage done manually with specific tools or through pneumatic cleavers, obtaining a very rough and more or less irregular appearance depending on the texture of the rock in question.
SAW‐CUT
The surface of this finish is not smooth to the touch and, however, more than enough flat and suitable for paving. Although not totally anti-slip, sawn material creates the comparatively friction than the material polished or finished honed.
SCRATCHED
The scratched finish is one of the most expensive options in terms of finishes, However, It provides a unique effect stone, this solution also requires more time to production.
WATER JET
The waterjet finish as the name implies is obtained from a jet of water, this can be adjusted according to need, thus achieving the various roughness levels.
PORTFOLIO
Each project is unique and deserves permanent, full monitoring. From the moment of choosing the product to their shipment the customer enjoys the know-how and extensive experience of our team.
