Wooden parquet is a reliable and durable floor covering. Grinding parquet with their own hands will come to the rescue in the event that the surface lost its attractiveness. 
The device of a wooden floor on the beams of the ceiling. And this can happen even with careful care, what can we say about those areas of floor covering, which walk in street shoes, move furniture.
When it is not necessary to polish the parquet?
Grinding of the wooden floor. Pay attention: in some cases, the flooring elements are so spoiled that it is meaningless to perform their grinding. This will not bring the floor to normal. Such serious damages include the following cases:

What will it take to work?
There are 2 ways of grinding: machine and manual. In the first case, more material resources will be required, and in the second case - more time and effort. Manual grinding is performed with a manual cycle. In addition, you can attach sandpaper to the sole of the shoe and sand the surface with your feet. These methods are quite laborious. 
The device of a parquet. To simplify the surface leveling, a grinding machine is required. There are several types of similar equipment, each of which is designed for a certain stage of work:
In addition to the grinder, an industrial vacuum cleaner is required to remove dust and scissors for emery. The following materials are required:
- putty;
- sandpaper;
- oil or varnish;
- brushes and rollers;
- trowel rubber.

Step-by-step execution of work
Cycling parquet own hands. The room should be freed from furniture, remove the skirting boards and check if there are any torn off elements. If torn strips are found, they must be glued in place. At this stage, the necessary parquet repair work is carried out. If the heads of self-tapping screws or nails rise above the surface, they should be drowned 2-3 mm. Next, the floor is washed and vacuumed. This completes the preparation, go to the main works. On the drum of the grinder, a coarse emery is charged. Depending on the nature of the finishing of the parquet, its size is chosen:
- for the removal of varnish or varnish - № 16;
- for removal of the top layer of a tree and removal of a paint - №24-40;
- a universal option for any work - №60.
First, the machine is carried diagonally across the roomfrom one corner to the other. After that go to one of the walls and drive the machine along the wall, and then parallel to it. With each next pass you need to move 10 cm. It is very important to observe the correct direction of movement. Grinding should be performed along wood fibers. Only on the turn is a short-term passage across. For artistic parquet with a spiral pattern, you also need to move spirally from edge to center. To ensure that there are no depressions on the surface, it is necessary to lift and lower the machine in motion. At the first stage of work hard-to-reach places are skipped. It is necessary to adjust the drum pressure to the floor. For this purpose, a special screw is provided in the machine. To eliminate stains of varnish in inaccessible places and in the center a "boot" is used. If a poorly processed piece is located in the center, the machine is moved from the edge of the spot to its center in circular motions. Near the edges and in the corners, movements are made from edge to wall and back to remove the top layer of the surface. 
Technical characteristics of parquet. Next, a thin grinding is performed with a surface grinding machine. As a result of this treatment, even the smallest defects should not remain on the surface: scratches, burrs, etc. One-time processing of pelts No. 40, 60, 80 and 100 is carried out. One time means a straight and reverse passages. Then putty parquet is carried out. The floor is thoroughly vacuumed to clean the cracks from dust. It is best for the putty to use a special composition, imitating the color of wood. Puttying is performed on the entire surface using a special rubber spatula. The composition should be distributed evenly to fill all the gaps between the individual parquet elements and on their surface. When the putty starts to dry out and is not sticky, but does not start to harden, it is necessary to make an imitation of joints. This work must be done very quickly. For this, a ruler made of metal and an awl is used. If you hold the ruler with pressure, you can make curved joints. Surplus fillers are removed with a fine grinding. This is done only after the formulation dries completely. Grinding of parquet is carried out with a surface grinder with a sandpaper №100. The pressure of the drum should be reduced, the direction of movement along the wood fibers. Grinding is carried out until the surface is perfectly flat. Back to contents</a>
Finishing
The treated surface is covered with varnish or oil. 
The scheme for replacing a rotten parquet board. The surface is thoroughly vacuumed to ensure a completely uniform application of the varnish. It is necessary to apply 3-4 layers of varnish. Each new layer is applied only after the previous one has dried completely. It takes about 4 hours. Before varnishing, a primer or a toning composition can be applied to the wood surface. For the application of varnish a roller is used. The entire surface is immediately covered with the formulation. It needs to be done quickly enough, as the lacquer grasps almost immediately. After the first layer, the pile of wood can rise. Remove it by grinding, sandpaper number 100 or 120. After that, all surfaces need to be re-vacuumed. Thus, parquet grinding with their own hands can be performed qualitatively only on condition that all recommendations are observed. This work can take quite a long time, but it's better to do it longer than to do everything later. Equipment for its implementation can be rented.
