Definition of sandpaper - What is it, Meaning and Concept

A sandpaper is a fish marine that is part of the suborder of the spits .It is a species that It can measure up to a meter long, with a small head and serrated mouth.

The sandpaper has a grayish body that turns whitish in the abdominal area and exhibits reddish spots on the spine, although the skin is not covered of scales , it has some corneal bulges of great hardness that make it very rough.That is why the human being uses the dry skin of this animal for the cleaning and polishing of wood and metals .

The idea of ​​sandpaper, therefore, can refer to the skin of this fish which, after a drying process, is used to clean and polish surfaces.It is also called a sandpaper paper that, with emery , sand or ground glass attached to one of its faces, is used with the same end.

The sandpaper , in short, imitates the skin of the fish.It is produced through the adhesion of an abrasive material to the blade, so that it can be used as a tool .

If a person wishes to varnish a wooden table, for example, they must first rub its surface with a sandpaper so that it is very smooth.The friction between the abrasive element and the wood will generate the desired result.Once the table It is sanded, you can apply the coat of varnish with ease.

Sanding wood correctly is not an easy task, at least not for a person without previous experience in this field.While the most obvious aspect of a piece of furniture is usually its finish, be it the paint or the varnish, this is not It may look good if an impeccable work has not been done beforehand.

With the use of sandpaper it is possible to remove the marks left by other tools on the wood, such as brushes and saws , and thus smooth and level the surface.This step is recommended to work the varnish or paint, to significantly increase the degree of adhesion.

One of the first points to keep in mind is that not all types of sandpaper are suitable for any type of wood.On the other hand, once we have chosen it, we should know that throughout the process we should use several thicknesses, from the largest to the smallest, to get a professional finish .It is important that the difference between one thickness and the next does not exceed fifty percent.

We should not underestimate the importance of this change in thickness, since it serves to eliminate any damage that has caused the abrasiveness of the previous paper.If we do not include this procedure in our sanding work, it is likely that when we reach the sealing or lacquering phase we notice certain imperfections, and then it will be too late to correct them.or the grooves that can be seen on its surface.The objects with curves present a greater challenge than the planes, since if we do not pay attention we can deform them because of sanding more parts than others.It is also important to change the paper as soon as wear .

To sand wood using sealant, it is necessary to let it dry before proceeding.To know if it is at the right point a test of sanding is recommended: if we see that small strips fall, then the wood has not dried enough; if, on the contrary, only white powder comes out when sanding it, then we can proceed.
