Getting to know the sandpaper
In this process, you can not select any sandpaper under the belief that they fulfill the same function since ignorance will lead to poor results in the finish. Therefore, we must know well about the classes to be found in the market following the numbering and grains.

The type of grain should be adequate. The most recommended are those of corundum, aluminum oxide or polyvalent. These grains have a quantity and it is indicated thanks to the numbering. The fewer grains you have, the more abrasion you will have, that is, sandpaper of 60 will be more abrasive than one of 240.

We indicated the numbering and then we specified the list so you can get an idea of ​​what you can use.

40-60 (coarse grain): It disappears traces of paints and varnishes, although it is much better to avoid this type of sandpaper when working with softwoods.
80-120 (medium grain): It is the most common in all the projects of DIY or carpentry. It works to repair flaws and smooth the surfaces.
150-180 (fine grain): Used both to give a smooth texture in the last layer of sanding and to open the pores of untreated woods.
220-240 (grain + fine): Sand well between paint, primer and dye layers that exist in your piece.
280-320 (Fine grain + fine): Disappears particles or remaining powder product of the application of varnish or paint. It is extremely useful if you paint with spray.
360-600 (fine +++ grain): Removes excess shine. It is often used in cases where several layers of polyurethane or varnish are used.
Considerations when sanding wood
One of the first questions when proceeding with this activity is to have a special tapping block ready for sanding, in such a way, it will be simple and easy to manipulate the paper by different surfaces. On the other hand, ensures uniform friction because if you ignore it and decide to do it with your fingers is latent the possibility of making more pressure in specific areas.

Use only the portion of sandpaper needed for the block and when cutting it, do not use scissors or knife is better with sharp edges of a table, beam, etc. Just take the paper that is resting on the surface, pull down and out from one of the opposite ends and ready.

Always sand in the direction of the grain of the wood because this way the very nature of the material achieves that the work is fast and with a perfect smoothing. As you go sanding, the paper will lose efficiency so you have to clean it by giving a few rough blows against a table so that the dust falls.
