Nitrocellulose Lacquer

A quick question. I just finished my first ukulele. And was wondering how many coats of lacquer I should apply after i sand seal ? Thank you in advance

Hah! Be aware if you get a quick answer to your question. The answer is just too broad. You need to consider what final result you want. Most of us who have done this for a while are constantly searching better and ways to achieve the finishes we want.
The StewMac finishing schedule is a good general place to start. You will likely adapt it to meet you specific needs.

OK, the quick answer? Two to twelve.

Thank you Chuck. Just so happens I'm using Stew macs color tone products

Whoops. I didn't know you were using water based. I've only tried it for a short period of time when they first came out so my experience with Color Tone is very limited. I guess I'm confused. Does Color Tone make a nitro finish?
Anyway, please post your results.

Yes that is what the can says I'm applying it over there sanding sealer

Yes, I see it. Rattle can correct? I used that once a long time ago with very good results. Good luck.

Don't worry about drips or runs, they can all be sanded out. I remember freaking out when I did my first lacquer job and got some drips. They are no problem, you can sand them out.

I'm currently finishing a Stew-Mac tenor with their aerosol nitrocellulose lacquer. Because the spray cans put out a lot less material than an HVLP sprayer, you'll probably need to do as many as 12 coats to get a thick enough finish to final sand without hitting wood. You'll need to do a bit more sanding with the spray cans because the mist is not as fine as what comes out of an HVLP system, creating a slight "orange peel" effect. And be careful when a can gets low, because they tend to spit as they run out of material. At least that's been my experience; YMMV.

BTW, next time I'm biting the bullet and investing in an air compressor and spray gun so I can do a decent waterbased NC lacquer finish. My wife is complaining about the smell emanating from the garage caused by the toxic stuff in the aerosol cans.

Thats what I'm building I changed the rosette and added a little purple hart to the heel . here are a few pics first coat of lacquer

Nice! I like the shell rosette. Much prettier then the plastic strips in the kit. I see you also got a neck made of something other than mahogany. I stained mine to get a closer match.
