  • Remove carpets and curtains;
  • Using a small chisel, detach the plinth very carefully;
  • Hammer all the nails protruding from the wooden boards;

The necessary works:

  • The process of sanding a floor from a natural treecleaning the floor of the old coating using a scraping machine;
  • sealing cracks and cracks with putty;
  • graceful grinding and scraping performed by a parquet processing machine;
  • sanding herd-to-be-touched spaces and corners;

Polishing the wooden floor

If you only need to remove the traces and imprint or slightly level your flooring, you can perform the updating of the wooden floor only. If you need to totally remove the long-standing coverage, then you need to make polishing performed for several times.

Updating

The old layer is removed or elementary grinded till it’s matt. It will be quite enough just to “walk” on the surface with orbital sanders.

Full sanding

How to sand a hardwood floorIt is necessary to make from 2 to 4 passes of a grinder. Sand a hardwood floor diagonally in the direction to the location of the fibers; wooden floors - strictly parallel to the direction of laying planks. Corners and edges before the final passage of the machine are traditionally treated with angle grinders. Then close all the cracks and seams, and after that, the clean the floor again. The next stage of work is processing sealant. After a couple of hours, you can perform grinding with a hand tool (using sanding sheets grit 120). After that, you will need to re-clean the floor thoroughly from dust and debris. Thereafter you can apply to the second layer of lacquer. It should dry well (for about 10-12 hours).

If you want to sand floors you should know that it is a qualitative report on the updating of the base at a ratio of considered as “work/results”. You can give you flooring the very original look by simulating different kinds of wood or aging equipment. One can even increase the environmental properties of timber applying natural oils and waxes.

Important pro tips

  • The result of grinding and polishing the wooden floorMore high quality polishing can be achieved by treatment with a three-disc grinding machine.
  • For best results, you can put auxiliary loads up to 110 lb.
  • It is really possible to perform polishing of parquet in the living space with a single-disc surface grinding machine. The equipment is more affordable, but the performance of similar units with the same way as the quality of the surface is significantly lower than that of similar devices with three disks.
  • It is important to remember that prior to the grinding work it is necessary to perform a careful inspection of the floor, because it is will show you if it is really necessary to perform the full grinding.
  • It is a terrible mistake to think that it is possible to sand the wooden flooring with sandpaper only – don’t follow the myths.
