Do you want to understand how to polish granite efficiently? Then you are in the right article! Without any doubt, natural rocks are extremely versatile and can be applied both indoors and outdoors, such as kitchens, bathrooms, facades, floors, etc.
However, for stones in their natural state to be used in projects, they must be subjected to a finishing process to make them suitable for the application. This is what we call polishing.
In today’s article, Cobral brought content explaining step by step how to polish granite efficiently. Keep on reading and learn how the process works, what you will need, the precautions and much more!
Why polish granite?
Granite polishing is the first finishing process to which a natural stone is subjected. This is an essential technique for giving the rock shine and making it suitable for the next steps, such as cutting and molding.
In this context, it is an essential procedure to have a well-finished surface. Whether on countertops, sinks or another application, by polishing granite you guarantee a shiny appearance and conditions to remain sophisticated for longer.
What do I need to polish granite?
The entire polishing process is carried out wet using automatic or semi-automatic polishers, always using abrasives in fickert format.
Check the list of all necessary items below.
- metallic abrasives;
- resin-bond diamond abrasives;
- gloss abrasive (optional);
- revitalizing liquids (optional).
To achieve satisfactory and long-lasting results, it is very important to use high-quality products specific to the service. This way, it will be possible to avoid losses and develop work that will provide complete satisfaction.
Step by step on how to polish granite
The procedure for polishing granite must be carried out using quality products and accessories. This way, the results will be outstanding.
Check out a practical step-by-step guide below!
Step 1: make the plates smooth
The first step is to smooth the plates, using metallic diamond abrasives. There are 8 different grits for automatic machines (30, 40, 60, 80, 120, 150, 170, 220), each grain is a different color to help you remember the sequence.
Step 2: polishing the surfaces
After smoothening, the next step is polishing with resin-bond diamond abrasives. They are available in 15 particle sizes, which are 60, 80, 120, 150, 220, 320, 400, 600, 800, 1200, 1500, 3000, 6000, 8000 and 12000 and 5 different alloys.
When reaching out Cobral technicians, you will receive the necessary instructions to choose the best sequence according to your machine.
Step 3: Final finishing
If you used resin-bond diamond abrasives up to 12000 grit in the previous phase, it is not necessary to carry out this 3rd step. Otherwise, you will need to apply the gloss abrasive to provide a mirror-like shine to the granite in the final finish.
Step 4: waterproofing
Finally, it is important to waterproof the surface. Despite its low porosity and being more resistant than marble, granite can stain over time — especially if it is applied to kitchen countertops.
If you want perfect waterproofing, apply Impercob from Cobral and protect the granite against liquids. It consists of a specific product for this service and which guarantees remarkable quality for the proper protection of the stone.
What should be taken care of when polishing granite?
Despite being a procedure that takes place without major difficulties, some precautions are crucial. In other words, you need to be careful to avoid situations that could put the results and quality of the service at risk.
Here are some precautions you need to take when polishing granite:
- use protective equipment;
- don’t give up quality abrasives that don’t break and wear out a lot;
- adjust the sequence to avoid excessive costs using too many abrasives;
- always choose quality items.
Furthermore, always carry out each polishing step carefully and analyze the service very carefully. This way, it will be possible to identify possible imperfections and resolve them before they impact the entire work.
