Spray tips!
 |
 |
Our aerosol spray tips have
a rotating aperture for horizontal and vertical spray patterns. We suggest the
vertical setting for large surface areas such as the top and back. The horizontal
setting reduces wasted overspray when working on narrow surfaces like the sides
and neck.
Before spraying, we recommend placing your spray cans in a container of hot tap water. The increase in temperature helps the lacquer flow better and reduces unwanted spitting. When an aerosol can starts to feel cold during use, we recommend switching to a warmed can as chilled cans are more likely to spit. Place the chilled can back in the hot water so it can be warmed back up and used again!
To clear the spray head, invert the can and spray for 2-3 seconds. Keep the spray
tips clean by soaking them in lacquer thinner between coats. This helps prevent
clogging and spitting.
Before spraying
Sand the wood to 220-grit or finer with the Gold Fre-Cut Sandpaper. Use a
tack cloth and vacuum to remove dust.
Fill the wood
Fill the pores of open-grained woods such as mahogany, walnut, ash, koa and
rosewood before spraying sealer. Apply the filler in small areas at a time, removing
the excess with a plastic leveler (or an old credit card). Let it dry 24 hours
before spraying sealer or lacquer. See the can for detailed instructions.
ColorTone grain filler can be used under waterbase or nitrocellulose finishes,
and can be tinted with ColorTone liquid stains before application.
Build a level surface with Sanding Sealer
Shake the can for at least one minute after the agitator rattles.
Dont spray too heavily. We recommend multiple thin coats, with the aerosol
held 8-10 inches from the surface of your instrument.
Spray 3-4 coats, allowing at least four hours between coats. Wait 24 hours before
level-sanding.
Between sealer coats, sand very lightly using a sanding block with 320-grit sandpaper
to remove any fuzz or lint that may appear. This is not the same as level-sanding:
use a light touch, being careful not to sand through to the wood.
A low humidity environment is important for best results in spray finishing.
Lacquer coats
Remember to shake the can for at least one minute after the agitator rattles.
Dont spray too heavily. We recommend multiple thin coats, with the aerosol
held 8-10 inches from the surface of your instrument.
Nitrocellulose finishes should have a total of 6-12 coats sealer, color,
and clear coats combined. The total number will depend upon how thick your coats
are, how much sanding you do, and what your final desired finish thickness is.
Beginners should spray 10-12 coats to avoid sanding or buffing through the finish.
As you gain experience, you'll find that fewer coats are required.
The first coat is your tack coat a very light mist that prepares
the surface for the regular coats to follow. About 45 minutes after spraying the
tack coat, apply your first regular coat. Keep all the coats thin: dont
try to build up the finish too quickly, or youll get runs or sags. (This
is especially true at edges, where the finish tends to build up heavily.)
Allow at least four hours between coats, and wait 24 hours before level-sanding.
If you do get a run or sag, simply let the finish harden for 24 hours, then level-sand
the blemish using 400-grit sandpaper on a backing block.
Cure the finish
This is very important: let the finish cure for 10-14 days before final sanding
and buffing. A hard-cured finish will buff out well, while an uncured finish will
drag and soften due to the friction of buffing.
Final sanding and polishing
Wet sand starting with 800-grit and finer Micro Finishing Papers. Hand polish
or buff to a high gloss using finishing papers and polishing compounds. The compounds
provided are formulated to be applied by hand with a soft cloth, or with foam
rotary polishing pads.
After final sanding to 1200-grit, start buffing with the #2 Medium Compound. #3
Fine Compound is optional, following #2 Medium for super-high gloss.
