When choosing the types of granite finishes, many questions arise.

So we will show you the most used granite finishes and some tips to help you choose the finish according to the use or location of the application.

 

Granite is a stone widely used in civil construction as a floor, cladding and decorative element because it has high resistance characteristics and is not susceptible to stains.

 

In buildings, especially villas, it is widely used on balconies, thresholds, parapets and can also be used as a floor or wall covering, which gives the houses a sophisticated and elegant air.

First, what is the difference between granite and marble?

It is important to understand the difference between granite and marble, as they are quite distinct rocks and granite has more finishes than marble.

 

Granite is a low porosity rock, so it absorbs little water (the amount of water can vary according to the composition and from colour to colour).

Granites have a grainy appearance as if they were several compacted stones.

 

Marble is a rock composed mainly of limestone minerals and has a more uniform colour (without granite granules) with more defined veins. It is a less resistant and more porous material than granite, so it stains more easily if it is not waterproofed.

How is granite extracted and transformed?

We extract granite from the mountains in large blocks that we then slice as if it were bread.

After cutting the granite into slices (which we call slabs) the finishing process begins according to the purpose for which it was created and a last it is transformed into a product (curb/kerb, tiles, counter, column…)

1. Polished Granite Finishing

The polished finish granite has a mirror effect and undergoes a long polishing process until the slab shines on its own. The granite slab is completely flat and has a glossy finish.

 

For instance, it is used in: floors in dry environments, such as living rooms and bedrooms, countertops, counters and sinks.

Maintenance is easy but it is also very slippery.

2. Brushed Granite Finishing

Brushed granite leaves the stone with a silky, silky texture and a little more non-slip than polished.

For this reason, atrium floors, corridors and other spaces that are not wet are more suitable.

3. Sandblasted Granite Finishing

In order to leave a non-slippery granite floor, the stone is “washed” with a jet of sand that leaves it rough.

It has a rougher finish than brushed and less than shotblasted or flamed.

This finish is sometimes used in strips on polished granite to create a non-slip area.

4. Shotblasted Granite Finishing

The granulated finish is made with the projection of thousands of steel balls, on the granite, which leaves the surface full of mini holes, making it non-slippery.

This finish is more common for places of high use such as street and square pavements. In homes, it is often applied in the frames of swimming pools.

5. Flamed Granite Finishing

Flaming granite is the most aggressive finish of all, done through the direct application of fire on the stone.

The finish is non-slip and the appearance is slightly rough but soft to the touch.

In some granites, the colour changes due to the aggressiveness of the flames (for example, the yellow granite becomes pink).

6. Saw Granite Finishing

granito serrado

The saw granite finishing similar to brushed, but slightly rougher.

Quite used in large squares floors without the textured aspect of granulated sand, for example.

7. Natural Split Granite Finishing

Natural split granite is the most natural finish of all. The surface of the granite will have a totally irregular appearance resulting from the moment of the cut. We call it the natural cut.

So, the result is a less invasive cut, that is, there is no metal contact along with the cut, as with saw cuts.

The cracked finish is used more on walls (as cladding), walls and rustic floors.

Now that you know the most popular types of granite finishes, you can make the right choice.
