COMPLET PROCESS NITROCELLULOSE




Wood Preparation

The wood must be free of imperfections and blemishes.
Sand with varying degrees of sandpaper to reach P 220. It must be sanded in the direction of the grain, until no visible sanding marks.
Remove the repelo. slightly wet the wood with a damp cloth and, when it is dry, very gently with a soft sandpaper to leave the smooth surface again. The sandpaper will start the raised fibers, which will no longer trouble again. If sanding very strong new fibers will loosen and have to repeat the operation. Anyway you can repeat the process, so be sure to have totally eliminated the repelo.

Wood stained (Optional)

Wood stain with concentrated dye dissolved in solvent. Let dry 60 min. before proceeding with the process.

Background (Optional)

It is advisable to use the same finish as background nitro but diluted with solvent 540421 50%. Give one or two hands, 50% dissolved solvent. Let dry hrs hours 2-3 at hand. Let dry overnight before applying the finish sanding to level.

Colored layers (Optional)

t is recommended sanding very gently (P 800) before applying the color layers. The surface should be as smooth and soft as possible.
Apply lacquer dissolved Nitorlak guitars 30% solvent 540421, colored with concentrated solvent in a maximum of 2% dye in proportion to the lacquer dye. It is recommended that hands or colored dye are highly concentrated to be applied as thin as possible in order to achieve the desired tone. Apply 2/3 hands a day, 4 hours between each hand. No sanding.

Upper layers

Apply Laca “Nitorlak” guitars. The lacquer comes ready to use, but may adjust the viscosity solvent 540421. If working in particularly hot and humid environments and in order to avoid “veil” in the lacquer retardant solvent drying should be applied to a maximum of 8 %
Apply two to three hands per day with 1-2 hours of waiting hand. Keep in mind that as they leave applying hands in one day drying time increases, since the previous hand is not totalmenteseca when the following applies. Drying occurs between one day and another makes the drying time of the first hand the next day again be short again.
Apply 6 to 9 hands, from 4 to 7 if a particularly fine finish or “open pore” desired

Sanding and Polishing

Leave “dry” finishing 3 to 4 weeks, preferably in a ventilated and dry.
Sandpaper with water to the desired point. (It is recommended if used automotive polishes sand until at least P1500)
Polishing, both by hand and machine.

General Tips and Tricks:

Finished with lacquer “Nitorlack” guitars, depending on factors such as the wood is tinted or not, and how many layers of color are given, must have a total of 6 to 10 hands in total, including background – color – finished with a minimum of 4 hands translucent finish. This will give an approximate thickness of 150 microns (0.15 mm) depending on how much sand, how much lacquer is applied in each hand and what thickness of finish is desired. If you have not finished any instrument previously is advisable to apply a 9-12 hands and safety of not sanding or polishing finishing excess, leaving parts of wood “Bare” will. As more experience with the product and the method of finishing is acquired, fewer hands are needed and can be achieved finest finishes.

If you choose not to use background can give a first layer of lacquer “Nitorlak” guitars diluted 50% solvent 540421, this layer must “wet” wood and penetrate it, favoring the adhesion of the successive coats of finish .

If an aspect of “open pore” desired product can be diluted in order to apply less solids in each hand. However, we must bear in mind that the possibilities of “sags” or “drops” will increase and drying times are higher.

If you happen to accidentally applying a ‘pick “or” glob “be taken, leave the finish to dry (overnight) and level sanding with sandpaper P400, preferably on a block of hard material. It also can “cut” the drip edge with a razor blade, a faster method and the accidents that can cause excessive sanding are avoided.

To become familiar with the process, it is advisable to test discard timber, to assess for itself the characteristics of the process of finishing a guitar with Laca “Nitorlak” guitars.

It is also advisable to use a surface “witness” to go on applying the lacquer layers while on the piece to finish. A paper stuck with masking tape to a rigid support (wood, thick cardboard) is a suggestion. So, first measuring the paper thickness with a caliper and then measuring the resulting thickness of the successive layers once dry, they have a pretty accurate idea of ​​the thickness of the layer to be applied so we can have a more accurate idea of ​​the thickness Of the same. A thickness of 150-180 microns (0.15 to 0.18 mm) ensures a fine finish, which respects the natural vibrations of the instrument, both to protect it, avoiding excessive thicknesses
