Diamond polished floors

Diamond polishing is one of the many existing techniques to polish and improve the quality of our floor.

Therefore, at BECOSAN®, we wanted to dedicate a special article to this technique, where we will explain what it consists of, the differences compared to other floor treatments, and the discs that are used to obtain various results.

What is diamond-tool polishing?

Diamond polishing is the ideal solution for floors in a certain state of deterioration as a result of daily use and that have stains, grime, and scratches due to their continued use.

It is at that moment when a floor must be repaired by using the diamond-tool polishing technique.

Thanks to diamond polishing, we can recover the initial appearance, and shine that the floor once had when first installed.

Diamond polishing can be used on marble, stone tiles, terrazzo, concrete and many more types of flooring.

The treatment consists of grinding the surface of the floor with industrial diamond grit pads that can have different grain sizes depending on the degree of wear of the floor.

Difference between diamond-tool polishing, polishing, and crystallization.

There are many different kinds of floor treatments (polishing, crystallizing, coating, etc.), and, in addition, each must be carried out depending on the state of deterioration in which the floor is in.

Polishing with diamond abrasives

Diamond polishing floors, as we have mentioned previously, is carried out due to the damage which has been caused to the floor by its use.

It is a process that allows us to achieve the highest quality finish and a spectacular shine, something that other treatments cannot. The surface, once the treatment has been complete, looks practically new.

Floor polishing with compounds and powders

On the other hand, floor polishing or polished concrete is carried out when floor surfaces are very deteriorated due to the traffic of people and/or vehicles, as well as the passing of time.

This technique is also usually done when the floor has just been installed, to level and smooth its surface.

Before coating a floor to create a shine effect, it is essential to first polish it if we want to achieve a first-class result.

Polishing floors strips or lowers the floor a few millimeters to remove any stains, imperfections, or cracks that could have been caused by falling objects or blows.

This technique is carried out on floors that have been eroded or attacked by cleaning products that have chemicals, such as bleach, and that, as a consequence, have lost their porosity, color, or texture.

It is also applied when you want to remove cement or rust stains that cannot be removed with ordinary cleaning techniques.

In short, it is carried out on floors that have lost the initial benefits which made us chose them in the first place.

To polish a floor, state-of-the-art machinery must be used, which strips the top layer of flooring and, simultaneously and continuously, removes the residue that remains from the polishing by sucking up the water generated in this process. This way we can make sure that there will be no stains or splashes on the walls, skirting boards, furniture, etc.

The crystallization technique consists of returning the natural shine to the floor that was lost due to it being used. This is achieved by using crystallizing products with non-slip properties and that also cover the pores in a way that prevents any dirt from penetrating into them.

It also can be used to repair thin and superficial scratches as well as avoiding watermarks after washing.

How to diamond polish floors?

Diamond polishing a floor involves a process that is carried out with a special polishing machine.

Depending on the degree of deterioration, we will use a kind of diamond or another, subject to the condition and specific needs of the flooring.

First of all, the floor must be pre-cooled with a lot of water.

Soil Diamonding

Subsequently, the polishing machine glides over the surface and its vacuum cleaner removes all residues.

Then it goes over the floor again using a smaller diamond grit pad which leaves the surface completely smooth and, subsequently, crystallizes to achieve a perfect and lasting shine that gives the floor a renewed appearance.

Machines and materials used to diamond polish floors.

Floor polishers are used for floor treatments such as diamond-tool polished, crystallized or polished, although they also have other uses such as sanding parquet with sanding discs, stripping or removing dirt from porous floors.

They are widely used in companies to renovate, maintain, or clean floors in private studios, commercial buildings, public centres, offices, schools, hospitals …

They are very easy to use. All you need is a connection to an electrical network and adjust the revolutions according to the specific needs of each floor.

Choosing between one grinder or another is determined by the type of work and surface.

They can be differentiated by the number of disc revolutions, the power of the motor, disc diameter …

It’s very normal to have doubts when buying them, so do not worry.

On the other hand, we have the polishing pads, which are used by the polishers to do their work.

As we have said previously, depending on the type of floor, we may use different types of pads.

Here below we will show you what pads we use on a daily basis at work:

How much does it cost to polish a floor?

The price to polish floors is not easy to establish, since it is essential to take into account factors such as the type of floor or the state in which it is found. Here you have more information: polished concrete floor price per m2.

And then, based on this analysis, other services such as industrial cleaning or expansion joints repair services may be added.

If the floor is very deteriorated, more effort will have to be made to recover its original state, so the cost of its reparation will be higher.

In addition, the polishing treatment which is used is another factor that influences the final price, as well as the cost of the professional team, materials, and execution time.
