1.- SUPPORT PREPARATION
- Sand the wood with P240 and P400 grit sandpaper. The wood should be free of imperfections and stains.
- The objective of this first step is to achieve a perfectly smooth surface without defects or roughness to proceed with the application of the first undercoats.
2.- APPLICATION OF THE WHITE OR TRANSPARENT BACKGROUND – NITORLACK PRIMER
- The background is the layer of varnish that will build the base of the finish, providing a uniform surface. We will choose white for solid finishes or transparent for transparent finishes that show the grain of the wood. We recommend a minimum of 2 sprays for a good anchoring process.
- We will sand with P800 grain between coats. Minimum application of 3 to 5 coats is recommended. We will apply product until we see that there are no imperfections, it is perfectly level and the pore of the wood is completely closed.
3.- APPLICATION OF COLOR
- We apply layers of color by sanding between them with P800, allowing to dry 24 hours between coats. It is recommended to apply a minimum of 2 coats and until a uniform finish is achieved.
Take special care when sanding the first layers of color to avoid peeling.
4.- GLOSS OR MATT FINISH – NITORLACK LACQUER
- The process of applying the finish is the same as the primer. We apply finishing coats by sanding between them with P800, allowing to dry 24 hours between coats. It is recommended to apply a minimum of 3-4 coats.
- In the case of a GLOSS finish, once we see that the finish is completely uniform and the guitar is finished to our liking, it is important NOT to SAND the last layer that we have applied and let it dry for 2 to 3 weeks to be able to polish and achieve the maximum brightness.
- In the case of a MATTE finish, the last coat will be the final finish, it cannot be sanded or polished. Only let it dry 48 – 72 hours.
- Sand with water in a gradual process with 1200-1500-2000 sandpaper until all the imperfections of the application disappear.
- Try to sand in a straight line without applying too much pressure so as not to make deep marks that with the polish will be difficult to remove. It is advisable to apply a few drops of soap to the water to facilitate sanding.
- Apply a few drops of polish to the surface of the guitar and to the polishing pad.
It is recommended to polish over 1500 to 2000 rpm without applying pressure to avoid overheating the finish. Check the heating regularly during polishing.
Carry out a first polishing process with MIRKA POLARSHINE 10 and the WHITE sponge. We must already get a mirror finish.
- Finish the polishing with MIRKA POLARSHINE 5 and the BLACK sponge. With this last process we will get an extra shine.
- Wipe off the polish residue with a cloth and the guitar is finished.
- Shake the sprays vigorously for 3 to 5 minutes before application. Apply to a witness surface before doing it on the guitar.
- A finish with Nitorlack, depending on different factors, should have a total of 6 to 10 coats in total, counting background – color – finish, with a minimum of 3-4 coats of gloss finish. This will give a thickness of approximately 150 microns (0.15mm) depending on how much is sanded, how much lacquer is applied to each coat, and what thickness of finish is desired.
- If an instrument has not been finished previously, it is advisable to apply about 9 to 12 coats, so that you will be sure not to sand or polish the finish in excess, leaving parts with “bare” wood. As more experience is gained with the product and finishing method, fewer coats will be required and finer finishes can be achieved.
- If when applying it happens that you accidentally have a “sag” or “drip”, the finish must be allowed to dry for 24 hours and level by sanding with P400 sandpaper, preferably on a block of hard material. You can also “cut” the drip with a razor blade, a faster method that avoids accidents that can cause excessive sanding.
- To familiarize yourself with the process, it is convenient to do tests on scrap wood, in order to evaluate for yourself the characteristics of the process of finishing a guitar with “Nitorlack” guitars.
- It is also advisable to use a “witness” surface on which to apply the lacquer layers at the same time as on the piece to be finished. A piece of paper taped to a rigid support (wood, thick cardboard) is a suggestion. Thus, by first measuring the thickness of the paper with a caliper and then measuring the resulting thickness of the successive layers once dry, you will have a fairly accurate idea of the thickness of the layer that is being applied and thus be able to have a more accurate idea of the thickness Of the same. A thickness of 150 to 180 microns (0.15 to 0.18 mm) guarantees a fine finish, which respects the vibrations of the instrument, while protecting it, avoiding excessive thicknessAlways apply thin coats. Let dry 24 hours and sand between coats. Apply in crossed hands to distribute the product well. Apply with a distance of approximately 15 to 20 cm.SAFETY RECOMMENDATIONSApply in ventilated places or with extraction. Wear protective gloves, clothing, glasses and a mask. Wash thoroughly after handling. In case of eye contact: Rinse carefully with water for several minutes. Remove contact lenses when present and can be done easily. Continue with the wash. Highly flammable liquid and vapor. Causes skin irritation. Causes serious eye damage. May cause drowsiness or vertigo
