What is the best option to varnish your guitar?<\/strong><\/h1>\n

One of the topics that generates more discussion in the guitar world is about the different types of finishings, its main advantages and disadvantages, as well as the importance it has on the sound of the guitar.<\/p>\n

Well, today we are going to address all these issues in detail and we are going to give our most sincere opinion.<\/p>\n

Polyester and polyurethane finishes:<\/strong><\/h2>\n

\"Poliuretano<\/h2>\n

These “poly”<\/strong> finishes encompass both polyurethanes and polyesters<\/strong>. Both share similarities and differences between them, although their similarities<\/b>\u00a0differentiate<\/b>\u00a0them from nitrocellulose<\/p>\n

They are products that are mixed with a hardener , and dry and obtain their final hardness through a chemical reaction; nitro finishes are single component and dry by evaporation.<\/p>\n

Unlike Nitro finishes that need many coats to cover the pore of the wood and leave a smooth surface, this type of finishes<\/strong> due to its composition, are able to do it with fewer coats.<\/strong><\/p>\n

This is one of its main advantages as it allows industrial manufacturers to varnish a large number of guitars in a short time<\/strong>, and therefore the varnishing process does not generate a bottleneck in the manufacture.<\/p>\n

In order to get a good finish, and being factories that use a large amount of product, it is ideal that each of them to go through a period of product testing and even consider modifying the composition of that particular polyurethane or polyester. This way you will be getting the best possible result.<\/p>\n

Therefore, if you buy your guitar from a manufacturer that is not a luthier who makes few units per year, the most normal thing is that they come varnished in<\/strong> polyurethane or polyester<\/strong>.<\/p>\n

These finishes, in addition to their speed of application<\/strong>, stand out for their rigidity<\/strong> once applied and resistance<\/strong> to chemical agents.<\/p>\n

Here polyester stands out above polyurethane, the latter being softer and thinner.<\/p>\n

With everything explained above, it is easy to explain now why with this type of polyurethane finish, it is more difficult to scratch the guitar, but it will also be more difficult to repair if the guitar is damaged, since the thick and rigid layer does not help.<\/p>\n

In addition, if the finish is too thick, which usually happens with polyester mainly, the guitar can lose its wooden feel and look more plasticky.<\/strong><\/p>\n
