Sanding is a process that will take a small part of the tree and restore the original appearance of the wood, if there is a great deal of damage, it is first necessary to repair the boards or to replace them (when replacing it is nice to look for old boards).
It is very important that the master who performs sanding is a professional and has nice machines. In many cases the masters remain after the sanding traces (dents) that are visible and the effect is very bad (link to a photograph of such traces).
The master does not always know how to sand to be able to level the curved boards on a smooth surface. This is achieved with different machine movements diagonally until all boards are level, then the actual smoothing begins to remove the rough slag from the boards. For this purpose, different types of sand pepper are grown.
Many companies offer low prices for sanding, which inevitably leads to inferior quality, in order to enter the price, they often skip sand paper and then the final effect is very bad (the floorboards sits roughly dotted as covered with grit). In order to achieve maximum quality, it is necessary to start depending on the condition of the boards, usually the old pine undercoat or with a preservative coated under the carpet for many years it is good to start with 24 number , follows the number 40,60, 80, (gap fill is made at number 80) follows number 100 and finally finishing is used 120-150 for a buffing machine.
In this sequence the effect will be maximum, and your floor will have a smooth and level surface. For wood floors in good condition (engineered wood, solid wood, parquet) that need only refresh, the high-end sander (60,80, 100-120-150) begins.
This is the easiest part of the sanding. Since the large machine (the shaft machine) cannot get close to the walls, there is always a distance that must be completed with the so-called winder. Here it is already very important for the master to be good otherwise, the floor looks like the whole of the comma, because either the machine is not set up properly or the master cannot control it. Finally, the corners remain, if they are not cleared and not brought to the level of the rest, under the effect is none, there are used small corner machines.
Generally, most customers require coloring the floor here, you should know that if the balance is left rough, the coloring is very bad because every scratch begins to see each commas, to have a well-colored floor need a very fine finishing of the board. Finally, we reach the finish line.
Hurrying to finish the project many of the masters missed an intermediate grinding on the floor
After laying the finishing base (lacquer or oil) after drying, usually 3-4 hours, sanding with very fine sandpaper 240-360 is required and then the remaining finishing hands are applied.
In this sequence of the sanding process we guarantee you a wonderful floor.
