Spraying lacquer with HVLP?

[bradleyheathhays]

Is it possible to spray this stuff from a gravity-fed HVLP sprayer with a 30 gal air compressor? The direction sheet doesn't mention it can be sprayed. Also, if it can, any advice on how to do it is appreciated. The only thing I've read so far is to dilute it with about 25% lacquer thinner before shooting.

Call Watco?

That is a brushing lacquer. Yes it can be sprayed It definitely needs to be thinned. How much should be marked on the can. I too suggest you call them to get specs on air needed and thinning needs. Will say this I hope you have a setup to do this kind of spraying. The fumes are dangerous and cleanup is not easy. If you have never sprayed lacquer before I suggest you find some videos to get ideas what to do and not to do. Your compressor needs to sustain air while spraying. 30 gal sure is large enough if you can control air flow. If you are doing small projects it maybe best to use rattle cans and save the clean up. Or use a waterbased lacquer. Better on environment and lungs and way easier to clean up. Good luck.

I use this water base lacquer for the furniture I make, I also use an HVLP gun.

One of the demonstrators at the last AAW symposium said he uses Hydrocote Resisthane, so I tried it - bought a cheap HVLP spray gun from Amazon and it did a decent job despite me being a novice when it comes to spray finishes. Highland Woodworking is the only place I found that sold it.

Same stuff I use. Easy clean up.

The reason my head's spinning on spraying this is because of the conflicting answers I'm getting. I called Rustoleum, the manufacturer, and the girl was quick to explain that spraying this product almost always results in a very undesirable grainy surface. I was left to speculate that some of it cures in the air before it hits the surface and remains granular, but I'm really not sure. The can gives no mention of spraying parameters.

I actually do have a good shop setup (at work) to do this reasonably properly. I would set up in front of two side by side 42" exhaust fans blowing out a 6' x 6' building port. The compressor at work is about 60 gal.

Considering I have proper ventilation to spray this non-water-based lacquer, are there advantages (other than cleanup) to using this Emtech water-based lacquer? I'm guessing the cure time and time between coats would be significantly longer. I promise I'll shut up about this and get to doing some trials soon.

Absolutely not!!!!! Same reactions with Cat stuff as with waterbased. Same burn in effect and as I said alot easier to clean. Just run water through the gun and then DNA to dry water out. As I said you have to get mixture just right when using brushing lacquers because you do have to thin it. Then there is the nozzle size you need to match up with its use. What might be a wise suggestion is to shoot with dewaxed shellac first to seal wood grains. I gave you my suggestions and wish you the best in whatever you choose to do. May want to experiment with smaller versions and see what works best for you.
