HVLP: What Tips to Use for Shellac? Karl, Leon?

[-MIKE-]

I got the HVLP sprayer from HF, same one as Rockler. I used it to spray some Zinsser BIN and it came out pretty good. However, I sort of just guessed at what tip to use and I don't know if it was the best choice.

So, to you guys who HVLP a lot... before I google myself to death, what tips are for what? The Rockler manual says .9mm for latex and 1.8mm for oils.

The HF version says it comes with 1.0mm, 1.5 and 1.8, and there are three different tips holes increasing in size. I assume you use the corresponding hole sized tip for different needles.

The BIN instructions only talk about an airless sprayer.

The guy at Zinsser said they recommend .05"-.07" (1.3-1.8mm) for HVLP for all their "paints." He knew I was asking about BIN, so I'm assuming that's also for the BIN. Is that correct. BIN is pretty darn thin.

For spraying shellac I generally use a 2.0mm needle in my Earlex 5000.

I generally spray a 1 1/2# cut (with a 2mm needle), and use either 99% isopropyl alcohol or denatured alcohol, depending upon the temperature/humidity. On hot, high humidity days here on the Gulf Coast I find 99% isopropyl is less prone to blush.

That said, experimenting is the only way to getting the best results with any particular setup.

I wonder what cut BIN is. Some of their other products are 3lbs, but I can't find info on BIN. I take it the higher the lbs the thicker it will be?

[Swingman]

IIRC, the instructions on the BIN can say Do Not Thin?

You are talking the pigmented product, and not the dewaxed shellac Seal Coat, right?

Yep ...

[Swingman]

If you talking the "Seal Coat" it is 2# cut.

[-MIKE-]

Correct. I was just wondering if I could equate the viscosity of BIN to the shellac you sprayed with the 2mm nozzle.

Thanks.

I had read that. I'm talking about B-I-N pigmented shellac based primer.

[Leon]

I do not use shellac and I don't spray. ;~(

[Swingman]

IOW, until Festool comes out with a sprayer, you will continue to just rub ...

[Leon]

I like to stroke'it maaan.

Maybe ask Wa'but, ooooh but I think Wa'but is'a to es'pensive.

On another note, I was given a bottle of Willett Wiskey, 119 proof. I am afraid to open it in an enclosed area.

[Swingman]

No hay problema ... being as dangerous as that brand of shellac thinner is, I'll be glad to assume that responsibility for you, as well as verify its safety for human consumption.

Sounds like something Radcliffe could use in his BIN. ;)

[-MIKE-]

Someone in here, besides Karl, was talking about using BIN and spraying... hmmmm...... I must be getting old, like you guys. :-p

Nailshooter, maybe?

[Swingman]

That's what Leon was telling you to do ... ask "Wa'but". LOL

[-MIKE-]

I knew I should've asked this on G+, instead of in here. :-)

[Swingman]

[Leon]

Yeah probably so, he always has a lot of info.

------------------------------------------------------------- Good moonshine is 195 proof.

Only reason it isn't 200 proof is that as soon as it is exposed to air, it sucks water vapor out of the air.

BTW, 195 proof moonshine makes a dyn-O-mite martini.

Were there problems with the finish?

If not, you used an appropriate tip.

I have 1, 1.5 and 2.0 mm needles and tips for my Apollo HVLP. With a .5

- 2 lb cut of shellac I would probably start with the 1.5 tip.

How thick a film are you laying down? 3-5 mil?

[-MIKE-]

I think even if there are no problems, that wouldn't be an indicator that a better tip might yield better results.

Thanks.

HTFSIK? :-)

My supplier sells film gauges. There're cheap.
