One of the final stages of work on leveling the surface, made of cement mortar, is grinding the concrete floor, which must be carried out according to all the rules.
Only after this stage of work, on the main surface can be applied all kinds of impregnations, as well as varnishes and paints.
In addition, in ground concrete increases strength, resistance to abrasion and the formation of harmful to health dust, and the base gets a more attractive appearance.
The technology of grinding has its own subtleties and nuances, but with the right approach it can be performed at home with your own hands.
For industrial purposes, special equipment and machines are used for grinding the base, and in the conditions of the house for these purposes it is possible to use an ordinary Bulgarian with a special nozzle.
In general, a concrete base is considered one of the most durable and often occurring coatings, however, in order for it to serve its intended purpose for a long time, it is necessary to polish it according to all generally accepted rules.
Grinding a concrete floor is the process that can not be ignored.

Features of grinding
The modern method and technology of grinding concrete base allows not using any other types of coatings.
If you grind this type of floor qualitatively and in accordance with generally accepted rules, the result will be an effective and most practical basis that will last for many years.
Such a floor subsequently does not require the cost of carrying out restoration activities and any investment in operation, in addition it can be successfully applied as a street cover.
If necessary, grind on a large area, it is advisable to use special equipment and machinery, such as, for example, a helicopter.
Doing work in the home with your own hands, you can use an ordinary Bulgarian.
At present, ground concrete coating has found wide application in large stores, offices, warehouses, as well as home conditions.
The polished concrete base itself is one of the types of construction work that allows to optimally level the floor and maximize its strength characteristics.
The first or preliminary sanding of concrete is carried out on the third day after the final casting of the cement base is made.
In its turn, the final stage is carried out only when the concrete finally solidifies and rises. In the case when the concrete is new, it becomes necessary to remove lime milk.
It occurs as a result of the fact that during the priming process a stratification of the cement slurry occurs.
In turn, the work on the old coating makes it possible to eliminate all damage on the surface.

Carrying out this type of activities with your own hands also allows you to quickly and efficiently remove all kinds of dirt, rid the surface of deformed parts.
In any case, after grinding, the base gets a fresh look and increased characteristics. In more detail, the technology and method of grinding are analyzed in the video posted above.
Grinding types
Grinding can be carried out in two different ways, namely, wet and dry.
The main difference in their methods of conducting is their cost, and the equipment is always used the same.
In any case, the machines and tools that are used for this process must equally cope with both concrete and stone surfaces.
The wet grinding method is more suitable for those floors that have either a mosaic coating or a coating containing marble chips.
In this case it is necessary to use special abrasive nozzles.
The result should be a floor with an ideal surface and a perfect structure that will have an appearance that is not much different from polished.
In most cases, if necessary, grind a concrete floor, use a dry method, which can be done freely and with their own hands.
This method has its own nuances and requires more time for carrying out all the necessary measures, compared to the wet one.

In the process of grinding, a large amount of cement dust is formed in the surface treatment, for example by a helicopter, however this dust is much safer than the cement slurry that is formed when the treatment is wet.
In addition, it should be noted that in this case you can immediately see the defects on the ground, and quickly fix them by grinding.
For the convenience of removing the generated dust, it is recommended to use special vacuum cleaners.
Of course, for professional grinding, it's best to use professional devices, such as a helicopter, but at home you can use a grinder with a special grinding head.
Stages of operation
At the initial stage of the work, it is necessary to determine as accurately as possible the degree of application of any coating to the concrete base, if any.
In addition, you should check the flatness of the floor and the presence of all kinds of defects. Also it is necessary to check both the strength of the face screed, its rigidity.
All this is necessary in order to determine the progress of the work and the required tool.
When preparing the surface for work, make sure that there are no different pieces of reinforcement, or some other metal parts that could damage the equipment used.

After this you can start removing from the concrete surface irregularities and old application.
This can be done by milling or by using appropriate grinding equipment.
Then get rid of the cracks and potholes found in the concrete field, by filling them with epoxy mastic.
After the concrete base has gained enough strength, proceed directly to the very grinding with your own hands.
Do not carry out these work on the floor that has not been seized to the end, since in this case it is possible to damage the device used for this purpose.
For work, it is necessary to use a special device with diamond disks with a corresponding grain size.
Even if it is planned to carry out works by the Bulgarian, the surface will need to be pretreated with a special reinforcing agent that will make the concrete more durable and resistant to various kinds of influences.
Polishing is mainly dependent on the grain size of the disc used, and the higher it is, the smoother and smoother the concrete surface will be.
After a short period of time after the machining of the substrate, special polyurethane varnishes can be applied to its surface, which will make it even better.
In the process of operation of a concrete base, various deformations may appear on it for a variety of reasons, which should be eliminated as quickly as possible.

For these purposes, there is currently a large selection of a variety of tools and materials.
In general polished floor has a sufficiently high resistance to possible damage, and various defects on it appear extremely rarely.
On how to properly grind a concrete surface in the home, more details are told on the video, which is placed above.
