For the compressor you want to try and match the min CFM. Remember at 10 psi the CFM goes up on your compressor more than you think. Don't waste your money see my link.

Where do you buy your air filters from or do they come with the guns?

So could I use a small craftsman 5g compressor or is that to small should I find something around 8g or.higher

Is that Chris Salmone’s partner in this video with you?

[@paul_hartsel24]

Do you recommend the same setup for stains as well?

[@cseliman]

Anyway you can talk about air compressor as well please. What type, how big and what to know about it in order to have a good quality finish for furniture. Thanks

[@pnwgrown_360]

I second that. Just bought a husky 60 gal compressor and want to know what I need to do to it in regards to like what type of filters / air cleaners you use

[@lilybecerra2035]

[@dairybarnwoodworking215]

Do you have any specific recommendations for spraying stain through an HVLP? I've sprayed Lacquer and had great results but I would love to stop brushing stain.

[@markgoingo5335]

I thought I am watching Jimmy Kimmel show. Did someone tell you you have uncanny resemblance?

[@hiseminencetheholymacdiarmada]

I think it would be worthy of note to mention that as you widen the fan, the material coverage will be less. So as you widen (or narrow) you fan size, double check your material coverage.

[@TyyDaymon]

Your hair didn’t move sprayed that too

[@perryharrison3652]

I love hvlp I use the Devilbiss that takes a zip lock bag inside the cup so you can spray in all directions and never have your gun skip from losing suction plus clean up is easier

[@wemoodydc]

What a great overview. Maybe the best I have been able to fine all over KZbin. Thank you for taking the time to make this!

[@SweetSillyFun]

Great timing on this. 2 quick questions / clarifications: 1. Can you use regular latex paints in these sprayers? If so, mixing recommendations? 2. Will a 6 gallon pancake compressor work?

Thanks Jonathan. I am proficient with Syphon feed spraying, but wanted to get into HVLP for a while now. Thanks so much for giving me some basic direction. God Bless U and Yours.

[@jonathanblackburn3449]

Aren't the guns you use in this video really "conversion" guns, not HVLP guns? When I think HVLP I think 5 psi (that's the Low Pressure in HVLP) with 10-20 cfm (High Volume). These guns must be run at much higher pressure (about 50 cfm) and low volume (3-5 cfm). I make this point for two reasons: First, these guns can't be connected to an HVLP turbine. They're designed to run off of a regular compressor. So if, like me, you have something like the Fuji SemiPro, these guns are useless to you. Second, and this I can assert from first-hand observation, these guns are much less efficient. They overspray a lot more than an HVLP setup. And third, am I totally wrong about this? Does HVLP not mean what I think it means?

[@Camden04843]

Jonathan- Is there any advantage to lvlp? I can’t find your exact kit on Amazon, but this is what I found…AEROPRO TOOLS R500 LVLP Air Spray Gun with 1.3/1.5/1.7mm Nozzles & Air Regulator, A610 Paint Guns Automotive, Car Paint Gun Sprayer, Paint Gun for House Painting, Car, Furniture, Varnish and Top Coat

[@citizen_koehn]

Any thoughts on a HVLP + compressor setup like this, versus the Earlex/Homeright Super Finish Max? I'm definitely more interested in the simplified form factor of the Super Finish Max, and it seems to work well for a lot of folks...

[@TheMarbo74]

Great video! The kit comes with diferent nozzle diameters. 1.0mm, 1.4mm and 1.8mm. Which one do you use for different finishes? Thanks

[@Metalbass10000]

New to your channel today, some really good stuff. My wife and I started a business in our home recently, as I was forced to take an extended leave from my profession, manufacturing process engineering, and production, management, and I am not the type of person to just sit on the couch doing nothing. So, we combined my prior experiences, with my education, and a particular passion of mine, music and musical instruments, with my wife's passion for art and color, as well as her work experience dealing with customers and the public, and we are building handmade, custom, electric guitars and basses. We are at the point now where we are looking at options for improving our finishing methods, and are looking for information regarding the differences, the pros and cons, strengths and weaknesses, in comparing HVLP with LVLP systems. We only have a small compressor and we are only finishing, at most, 3 instruments at a time, often just one instrument. We build all of our instruments using only high quality exotic and domestic hard woods, tone woods, many of them being highly figured pieces of these woods. So we will almost never be using paint, and opaque coloring, covering up these extremely beautiful, and extremely valuable, pieces. Applications of stains, dies, or other pigments for coloring, will usually be done by hand, or with a small airbrush kit that we have. The HVLP or LVLP system would be almost exclusively used for finishing of the instruments, like an application of a poly, a lacquer, etc. Any advice, Insight, or information, would be greatly appreciated! Thank You

[@katzmosestools]

I could spend hours answering this. Best advice I can give you is work hard and stay true to your passion. Sounds like you're on the right track. Cheers

[@jisezer]

Thank you for the awesome video! When I watch your videos I always feel empowered to do the projects after.

[@katzmosestools]

Thanks bud! That means a lot!

[@gabesmith6475]

So how well would this work for a production setting? Our company uses water based polyurethane. We push out 75-100 end table stumps(3 coats of poly) and 20-30 tables (4 coats of poly. coffee tables, sofa tables, benches, and dining tables) a week. Just wondering if this would be practical or would we have to refill the hopper an obscene amount of times

[@littlebeebs1]

There were many typos in my previous comment. Do you have any tips for making Alkyd Day Glo oil based paint stick to wood ? I tried primer. That didn’t work. I’ll mix the paint three parts paint, and one part paint thinner. I am thinking that maybe the paint dries in mid air before it even hits the word because it has been atomize to be such a small particle once it leaves the gun . Just a theory. These are for indoor blacklight golf courses in rental houses. They will be getting a lot of traffic. The paint literally brushes away like powder even after drying overnight.

[@CGphotoOp]

What about using a LVPL spray gun for water based poly? What’s a decent sized compressor and tip?

[@hurcorh]

Anyone contemplating the Fuji Q4 or similar, I've had mine for a year with the suction feed T70 gun. Really enjoy using it. I have recently started using the 3M pressure pot and find it a great addition.

[@PapiSmerf]

I have the mini 4 and I love it. Can't imagine using anything else now that I've got my hands on it. I use the 3M pot too and it's a mandatory accessory in my opinion, being able to spray at any angle and never worry about the consistency of the paint feed is just so nice. Cleanup is a dream. It's one of those buy one cry once purchases. Yeah I spent $1500 on my setup. Yeah, I also have perfect finishes on everything I make for the rest of my life. I doubt these things wear out to the point they can't be rebuilt. I've sprayed everything from boat epoxy to super-thin poly and even painted a living room because I could. You've got to deliberately search to find things you can't do with a Fuji setup.

[@AJstanton3]

Water always comes out the gun great. Actual paint or finish is different. Hvlp are ver time consuming.

[@macbook12345]

Love your videos you have a great delivery of the information. I had a question about compressed size. I imagine using an HVLP you can use a smaller compressor. If this is a correct assumption how small a compressor would you recommend.

[@belladonnaRoot]

Just FYI on the compressor vs sprayer air usage: most compressors rate themselves on SCFM (Standard cubic feet per minute, ie, 1cfm at 14.7 psi absolute), and most air tools use CFM at 60 or 90psi (~75 or 105psi absolute) to make their product look good. So if a compressor says it produces 5 SCFM at 60psi, it's perfectly matched for a tool that consumes 1 CFM at 60psi. A standard Porter-Cable 6-gal pancake compressor produces 2.6 SCFM at 90 psi (0.36 CFM of 90psi air). Your air sprayer specs out at about 5 CFM at 45psi (20 SCFM). So that compressor is going to need something like 8 seconds to recover for every second of using that sprayer; not unworkable but not ideal. It's dumb and confusing, and has lead to many an undersized compressor.

[@Novicks]

What formula are you using to calculate this? I'm trying to decide on an appropriate size compressor to get for doing HVLP spraying as a hobbyist or to just get a small compressor and a turbine system.

[@Camden04843]

Jonathan recommended an 8 gallon compressor that he said works great. 3.7 @ 90 PSI. Could that be correct? He has the link posted

[@jgemeinhardt3955]

Jonathan, I've watched this video now several times, very informative and great content! One question, currently I'm building a dresser with seven drawers and was curious to know if you prefer spraying the lacquer on the long pieces of the drawers (edges half-rounded) prior to cutting, gluing and assembly or after the drawers are assembled? It seemed to me spraying first has less chance of marking up the raw wood and the joints will still have unfinished wood for the glue to hold. Thanks!

Miller Lisa Wilson Linda Harris Thomas

[@danielfiddler5014]

Nice. Thanks for sharing man. 👍🏼

[@eksine]

those water / oil separator filters are not enough for water, for automotive they just attach a leas hose about 8 inch or so and put a plastic ball water filter right at the bottom of the spray gun, inside those plastic filters are many layers of absorbent material, it almost looks like layers of cotton or something, it's $4 per filter, harbor freight has them. I learned the hard way after trying to figure out why I still had water coming ou of my spray even though I had 3 filters after the compressor. also your compressor looks like it's a tiny 8 gallon one, that's kinda small, 21 gallons would be better. and also you can make an aftercooler for the compressor using copper tubing lines at the hardware store and using a flaring crimping tool and random tubing joints

[@terrmaso]

You forgot to talk about the compressor.

[@handy-remodeler]

So you didn't thin the lacquer?

[@deanrantala]

Everyone in these videos with HVLP always talk about starting at 10 or so PSI. Honestly... I have never seen an HVLP gun that will even begin to properly atomize paint until you hit 20 or more. At 10 PSI - even 18-20, the paint is going to come out like tiny pebbles. Is there just something I have been missing all these years? Are there people out there that can actually spray paint out of an HVLP correctly at 10PSI?

[@albertshilton5336]

Really Good video. But, how about maintaining these guns?How do you clean these guns after each use? Thanks, Al

[@jimspry9188]

Can you spray epoxy resin with hvlp guns?

Timely video, just started looking into upping my game with regard to hvlp . I use a cheap all in one unit from Aldi for spraying shellac and it works well but my wife would like a big bathroom unit made and some new kitchen doors which I would like to spray with probably 2 Part paint

[@ekitching]

Nice informative video, good work. I wonder if a LVLP gun would work. Guess I will give it a try. I like how you put on that paint suit and wore gloves, very safe and a good idea.

[@MJ-nb1qn]

I thought HVLP implied using a turbine based air supply? So is the really HVLP?

[@katzmosestools]

Yes. Pressure is regulated at the gun

[@MJ-nb1qn]

Jonathan Katz-Moses - Thanks. Showing how you clean the gun up after different finishes would be great. The clean up is what has scared me off spray guns. Also, how long can the gun sit before spraying again with different finishes?

[@MD-en3zm]

HVLP can be either turbine powered or compressor powered. The guns used here are hvlp but work with a compressor. This is a cheaper option for anyone who has a good enough compressor.

[@crackerjack3359]

Stay safer?? The respirator filters you are using are strictly for dust and offer minimum protection from solvent sprays. You might as well be sniffing glue. Otherwise good video. Thanks,

[@vagelistassis7441]

May need to give an HVLP a try. I've always used airless... yes, really. Hot lacquer, pneumatic stirring on a 55 gallon drum. Of course we would turn out a high volume of cabinet, church trim....

[@BariumCobaltNitrog3n]

Not shaking the can of product really only applies if you are brushing it on. The strainer (filter) eliminates any bubbles. Even if they made it to the gun, they would be atomized. If they made it through the gun and the filter, they would pop in the air. If they didn't pop, that's a superbubble!

I've only used a sprayer a couple of times, but a couple of things I noticed. First don't spray it in the garage. Everything gets coated in a fine dust. Second, don't use it for finishes such as stain that need to penetrate the wood.

[@johnzannisplasticsurgery]

Do you thin down the water-based poly with additional water before spraying?

[@andrecastro7730]

Hey Jonathan. How those guns relates to the electric ones? You can also make the same adjustments? About the tip size, you can adjust to deliver small amounts of material even with a tip like 2.6mm?
