I’ve read the instructions on the Enduro black lacquer I’ll be spraying this week. They give specific info on temp stuff, but nothing about humidity. I’m spraying this on very small (1/4″) quarter-round moulding, not on a big wide flat surface. So….what do I need to know about humidity. We’re having “chance of showers” the early part of this week, rather than the sunny weather previous. TIA!!
Ah…and I’ll probably spray a seal coat of shellac. Should that be a 1# cut for a small HVLP sprayer? Considerations re: humidity??

Well, Enduro is water-based. I don't think humidity is a factor.

LOL something like that.
;-)
Putting down a sealer coat of Shellac is a great idea and I believe is along the lines of what Enduro recommends. And in a round about way it's because of moisture... just not ambient humidity in the air. It'll keep the Enduro from raising the grain.

OK, back to part b of the original question: What cut of shellac should I use for spraying (small HVLP unit)? How much do I need to worry about humidity. It's about 50% in the shop, but I have a screened room set up outside for spraying these tiny little mouldings.

Is it a turbine HVLP? If so, I have zero experience with those.
I would think that a 1.5 lb or 2 lb cut would work well. I also have limited experience with Shellac. At least with clear Shellac. I've used lots of the white pigmented shellac primer.
Hi, Kevin, thanks. Nope, not a turbine.
It's supposed to stop raining tonight. I'm just gonna go for it, get a piece of MDF and practice my technique. Never sprayed with anything but a can before, but "it ain't rocket science" right?!forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)Another proud member of the "I Rocked With ToolDoc Club" .... :>)
A 2lb cut will spray just fine in an HVLP system. I've used a lot of solvent-based (real) lacquer here in Florida without any issues. I had some blushing before I got the good sense to add a filter to my air line to remove water, but we live and learn. :-)

Hi Bill, thanks for the input. I'm thinking about thinning it to a 1.5# or so just because it's a sealer coat and not sure it needs to be as heavy as a 2# cut. Fla, eh? I used to live there (little girl).

Hey Jamie,
Yeah, a 1# or 1.5# cut is just right for a seal coat. I should have clarified that I sprayed a 2# cut with my HVLP as a finish coat on some cabinets that didn't need a heavy finish.
Muggy? That ain't the half of it. Katrina may have missed our part of the state, but it's still drawing super-moist tropical air over us!
Take care.
