It is necessary to know their secrets to be able to do a good job and achieve the most perfect finishes possible.
Here are some tips that will be very useful for you, to encourage yourself to do your own work and renew your decoration:
  • You can sand by hand or with sanding machines. The latter are useful when the surfaces to be polished are large. Otherwise, it is convenient to make a hand sanding, especially in corners and joints.
  • It is convenient that you go grading the thickness of the sandpaper: you start with a thick one and finish with a thin one.
  • In the wood you must always sand in the sense and direction of the grain.
  • To make the task more agile, the sanding more even and your fingers less tired, you must place the sanding sheet around a rectangular block (at least 2 centimeters high) made of wood, cork or other compact material.
  • Depending on the surface you are going to polish sandpaper is used to water (which can get wet) or trandicional, to dry. They exist with aluminum oxide and also coin silicone carbide (this one you can use it with water).
  • If you do not have a sander, you can use the drill with an accessory to sand or glue a piece of sandpaper to a rubber disc, which should be changed as it is worn. Anyway, the finish is always given by hand and with a fine sandpaper.
