Technically, this is really Part 4 of our Wall-Hanging Tool Chest build, but because I focused so strongly on waterborne finishes and HVLP (High Volume Low Pressure spraying), it received its own stand-alone title.
When I made this project in the Guild, I asked our members what type of finish they would like to see me use. The votes came in and the majority of folks wanted to see a waterborne finish applied via HVLP. So my finish of choice was General Finishes High Performance. I used the Earlex HV6900 to do the spraying and I was thrilled with the results. Even after a couple of year of use in the shop, the finish is still holding up very nicely!
This video serves as a nice introduction to the chemistry behind waterborne finishes, HVLP techniques and spray gun maintenance.
Topics Covered:
Waterborne finish chemistry
Glycol ethers
HVLP
HVLP Gun assembly/anatomy
Basic spraying technique
HVLP gun maintenance
Bringing more "life" to waterborne finishes

Found your video when I was searching on this topic. I used you tip on pre-raising the grain and it worked very well. Thanks for the great viseo.
Nice video. Clear and concise. Not too long winded. Salient information covered. Should inspire and encourage non-experts to go ahead and experiment. One point I would add and emphasize is to never let the sprayer falter in its movement...in other words if you have the trigger depressed and there’s finish flowing from the gun you should be moving. If you think a spot has too little material on it, give it a minute or two to tack and hit it again. Thanks.
This video changed the way I view and use my HVLP sprayer. I tried a water-borne clear finish on my last project and the outcome was excellent! The finish didn't need any thinning, and sprayed on perfectly. Drying time was quicker than I expected, and the lingering odor was minimal compared to the other solvent-based finish I normally use. The final finish (5 thin coats later) was very hard. Thanks for changing my mind and practices!
It's hard to detect all that you did on your surfaces, but these vids you make are priceless and valuable to me THANKS!!
This is mammothly helpful! Thank you so much!
Enjoyed that as usual. Interesting tip on the linseed oil, but if that amber was the look I was after, a coat of quick dry oil urethane or sanding sealer. 220 sand, vacume and then top coat with clear water base for durability and depth.
Best generous, intelligent channel. Glad I discovered it. Thanks
@jdrury Watch the video closely. You'll notice that when I'm actually spraying finish, the doors are no longer sitting next to the case.
A ton of great info, and the linseed oil tip was the icing on the cake. Very helpful, Thanks!
I agree explanation is incredible every bit of the video explains everything you need to know about spraying.
Truly a master craftsman. I’ve learned much today thank you for taking the time to present the audio, lighting, equipment setup and finally the content was game changing. Thank you indeed.
I actually don't do much with paint so I'm not the best person to ask. I find the guys at Sherwin Williams or Frazee can usually point folks in the right direction for paints.
@ArtisanWoodworker You can. As long as the BLO is fully cured you should be OK. The water-based finish might still raise the grain. And you might even consider putting on a sealer coat of dewaxed shellac before applying water-based, just to be safe.
Thanks so much for this video. I like the tips and the thorough teaching. I had to create a paint booth inside my garage though after getting way too much 'dust & debris' on my finishes while painting outdoors.
It can definitely help Dan. The Earlex units really only give you two options for adjustment, fluid viscosity and tip size. And if the unit is low powered, you might have a harder time with the thicker-bodied finishes. So yes, I do believe upgrading is a good idea if you're having significant issues with the finishes you want to spray. Also, consider looking into the Fuji units as a higher quality alternative.
@TheWoodWhisperer That is good. It means that an oops to the lens is a whole lot less than a new lens.
Thanks for the info in the video. I plan to have a spray system when a get another shop up and running. Thanks again.
subscribed! nice job. understanding the technical aspects of a product clearly shows that you commit yourself to quality productions. Now on to being up all night watching more of your videos!
@ak99372 Well the real key is to apply it very thin. I usually dilute mine by about 50% with mineral spirits, wipe on, let it soak for 3-5 minutes, and the come back and wipe up all the excess. Then after several days, the finish is usually dry enough to work with. Temperature and humidity can slow the curing process down a bit so keep that in mind.
I would probably try to find a decent stain to bring the two woods into the same color family. Shouldn't be too hard to get them close.
And thanks. Glad you enjoyed the video. :)
I always wear a respirator even when spraying outside. As for dust particles, that is definitely a concern but you do what you gotta do. A makeshift knockdown spray booth would be a nice upgrade for sure.
Agreed. It's a good unit for the price range. But if you have $100 more in your budget, you can get a pretty significant increase in overall quality.
Dude you are so well versed! Love all your videos. Very helpful and as always thank you...
@materiasacra I actually do use a filter at all times just to be safe. So technically, the spotting was on the filter and not the actual lens. But I try to treat the filter as if is the lens. This video was filmed over a year ago so fortunately I have come up with some good solutions for filming myself spraying. :) But I like your idea! I'll have to give it a shot.
excellent explanation on the water borne dynamics thanks
@ShallowJam I haven't worked much with Bamboo but I imagine it responds similarly to wood. If your test area is rough to the touch then you should probably pre-raise. But I really don't know if bamboo exhibits the same grain raising properties as wood. Just rub some water in and you should be able to tell. But in terms of staining and clear coating, it should work quite well regardless of what system you use.
I do HVLP on wood doors, all trim, bookcase, cabinet, etc, to automotive finish grade on standard job sites (no spray booth, fighting dust & debris and other contractors). You never raise the hewn with straight water and 1st sand is a choice between post-primer or 1st finish coat. Primer is the water bath that pulls up, grabs and brittles any hewn. Water is a wasted step. Never use a spray cup unit inside a small cabinet. Use a free gun for mobility w/ compressor.
This very helpful and clear to follow, If I have to spray, I use Cellulose lacquer as this dries very fast as I to don't have a spray booth.
Great video!
Who let the dogs out? Woof, woof, woof, woof... couldn't resist
thanks, I am new to water base top coats. So you just put on the linseed oil wait 4 to 5 days to dry, then go straight to the water base top coat with out doing any further surface prep.
thank you thank you thank you for your articulation and scientific explanations
Really good video! I once finished some parts outside and little bugs started to land on the pieces and got stuck in the finish and that freaked me out ^^
Spray inside
That is one killer back yard.
Haven't used it much myself. But I think you might want to take a look at General Finishes Endurvar line. I have used the gloss version and it is pretty amazing.
My guess if you have come a long whay in your spray game and no longer spray a finish outside, woot I love laying on a nice fine finish... You do good work and thanks for all the effort you put into your vids!!!
very nice explained, great video
Love the video great job explaining everything 👍🏻 I also love the music 🤘🏻 sometimes when I spray the corners on the inside of a cabinet I use the circle fan I mark the volume knob for wide fan and circle so when I flip the tip I know how much material to use
@smfield Thanks for asking. She's not having the best pregnancy. 6 months into it and she's still dealing with constant nausea. Although its getting a little bit better lately...
Excellent video. Good explanation. Thanks
@scarmenl actually I always have a clear UV filter on at all times. So fortunately anything that gets on the "lens" is really just getting on the filter.
@slow69ride Neither. I try to use a brush attachment on the shop vac when possible. And the blinds are purchased. I'm too lazy to build them. :)
Super helpful, Marc. Thx so much! 💛😎
GF Enduro-Var will darker wood as if it were an oil finish. I love the stuff. Get the look of oil, but the clean up of water! It's not cheap, though, about $90/gallon from Rockler.
+titanwr I have used Enduro-var on a whole house worth of cabinets and closets. I tested it on some high use knife blocks first. Pretty tough finish.
The best presentation I have seen in ages. Hell I wanted to know what spray system you were using and, pow, there was the flash card saying Earlex 3 stage. It's got everything and for that reason I have downloaded it for reviewing when finishing. Many thanks
Jeff Harmed Hi Jeff. Sorry to go off topic a bit but I have a question. How do I download a video into my I-pod mini, Or I-phone? I would like to watch it when I'm away from wifi. I don't have cell service with this iPod. mini. Any information you can provide would be appreciated. Thank you.
I really appreciate your videos. I want to learn more about finishes and application of them on my various projects. I'm having horrible results from my finishing skills so far and want to get better. Maybe a spray gun will help but I need a spray booth.
David
Thanks for the great videos used the one for the table saw sled and now used this one on HVLP and Water Bourne finishes.
Was un Happy with trying to get Perfection from Gloss Poly and being disappointed even tried using my HVLP from Rockler and still I was not Happy.
But With the Water Bourne I am as Happy as a PIG in the Mud Puddle Just learned to live with the Clear Semi Gloss finish though I am going to try some wax after it dries for a few days.
Keep up the great Videos
@AReptileMan I like pre-finishing whenever possible and sensible. Save lots of time and effort.
I don't know if they have a size for your camera but for a lot of cameras they have a clear filter lens to protect your cameras lens in situations where you are concerned that you might get something on the lens that might damage the glass.
When removing the nozzle, shouldn't the trigger be depressed to avoid the needle scoring the back of the nozzle?
@ArtisanWoodworker Nope. It is really for water-based products only.
@conrad2001 Thanks. :) We are in the west valley area.
Like the Dunder Mifflin T-shirt! Dwight rules!
Great video's!
Very happy for your video.Nice.Thx
JB You should use a water trap attached to the air hose before your gun.
When you demonstrated you giving your gun a "good shake" before applying the next coat of finish on your project i noticed a rattle in the can/gun, do you have bead or beads of some sort in it to aid in the mixing/stirring the finish as you are spraying?
@squidskunk Perhaps if I had a nice spray booth to finish in, but I'm spraying outside. Not sure it makes a bit of difference in my situation. Boy I sure to miss spray booths.....
The Wood Whisperer build a small one out of cardboard and a square fan with air conditioning filters real easy great for small projects
waterborne is the only product I use for kitchen refinishing
Excellent video! Thank you.
What about hitting my coffee table im finishing with Varathane Water Based Polyurethane Crystal Clear Semi-gloss with polishing paste wax or something will that bring a better look to it rather than just the poly by itself? Which the table is being stained with Slate color stain...
Don't know the exact numbers, but I find any turbine to be loud enough to require ear protection. So they are all the same to me. :)
Emesis gravidarum, that's tuff. Hope she starts feeling better soon.
hi,
I have a question. you use an oil to get that lively look before you finish is with a water based coating. Doesnt that give problems with the attaching of the coat?
( exuse my english) :)
They claim it's okay providing you wait 72 hours or more or something like that.
Thanks you are great! 41,500 subs and make the time to answer a guys question thanks again look forward to next vid. Will see what I can come up with on the stains so much for dutch oil on this one
After you raised the grain & sanded your project what method did you use to clean the sanding dust off of it prior to spraying the finish on the project?
should do a contest for one of these hvlp systems, could really use one
Very good video
I have a crazy idea to ask, what happen if I spray water primer paint and then spray varnish finishing coat?
Why would a person want to put a water based finish over an oil finish? Is it for the hardness, durability, spray ability, or what of a water-based finish?
I have a Fuji Q4 gold with a gravity gun and I couldn't find the way to spray waterborne laquer from valspar zenith, I got all tips and middles, I thin the laquer up to water and do not spray fine instead it spray like taxture, plz help
Yeah that's pretty common. That's a bleeder style gun. That's how it is designed to work. Just make sure you direct it away from the work when not actually spraying.
Good informational video
Links to purchasing the equipment your use would be nice.
@immemous yep.
A bit OT but what respirator are you using here? It looks like a cartridge with a pre-filter attached also. It's pink like a 3M P100 but those are round and your's is the shape of a cartridge.
really wished I watched this video like 2 years ago.
Thank you.
I know this is an older posting, so hoping you can answer. How heavy are your layers of spray? I am acutally using a turbine sprayer with Varathane water based polyurethane. I put on a very light layer initially and then went with a fairly thick second coat.
@attainableapex We just did one recently. Missed your chance!
Hey Marc, what are your thoughts on Endurovar? I'm told it's more durable than HP and it supposedly gives an oil look like the board with boiled linseed oil. Just wanted to get your thoughts if it is actually better and if it does look like the board with oil?
@Pedrofreestyle97 yep.
Have a question. Shouldn't you only tighten the needle screw only after you have installed the tip to avoid damage to the needle?
+gary24752 Maybe. But I've never given it much thought and never damaged a needle. They're not really fragile. Just don't force it in and the needle should find it's way through just fine.
Only problem with adjusting the flow rate using the water to begin with, is that water will have a lot lower viscosity than most finishes and the flow will be different than what you're spraying.
I have a waterborne paint, Ben Moore Satin Impervo.
What do I use to thin it? Alcohol then water? What ratio 1 to 1 alcohol to water.
What kind of alcohol denatured alcohol?
Thanks.
Videos are very informative.
Good, instructive video for water bone finishes. Subscribed!
I have to admit it can get confusing and there is limited info even from the manufacturer on these things
To sand or not to sand between the coats. I've seen some that don't send between the coats.
I've seen some start the second coat on top of the first coat with a HVLP gun.
I need to do it indoor ( I have 3 panels 4x8 to spray), unfinished room with a window, what's the best setup for this.
Some people say that if gun is not used for 5 minutes it has to be cleanned.
My boards are stained, oil based, do I need to hit them with water and I am concerned that if I raise any grains I'd impact the stain coat.
Any tips would be welcome!
thank you! the only one who say the truth about solvents. What type of filter do you recommend for this kind of job? thanks!
Did you move I couldn't tell what you were spraying was it light color our a clear coat been thinking about water base product s but I'm sure not sold yet !! ??
a very well done video, thank you. i am a professional painter in BC and have just started using a Graco hvlp turbine. can you recommend some better quality latex for spraying trim in new homes that works well with HVLP? Also, for thinning i have used extender. my results so far have been disapointing.
Nice tutorial. Thank you.
Thx.
great vid thanks for all the tips
Is this Earlex model HV6900 or 5500 - Spray Station HVLP Paint Sprayer system?? What do you use at this time to spray dye or stains. thx
What sort of psi did you have going to the gun using this product? Great video. I watched to see this info but you didn't mention it. Cheers.
Hey Wisp! You really shouldn't stick the gun needle into the gun before you fit nad tighten down the nozzle. If the needle goes just a little too far you'll ruin both parts. Fit and tighten the nozzle then insert and snug the needle gently into the nozzle. I have to say "GREAT TOOLS" I'm turning green all over and it's not just cause I'm Irish.
good video. What was the song used when spraying. It's pretty rad.
What is the difference in a stand alone and 3 stage? Thanks
i paint auto's...using an elevated screen/filter holder is a mistake...airborne particles can still enter the paint cup and destroy the finish...place the screen/filter directly on the top of the cup...just fyi
Question Refinishing oak baby changing table I found at thrift store. Question is what do you do when after you have sanded off all old finish and you find some red some white oak what do? Just run with it? use some kind of sealer to get it to finish looking the same? or just enjoy the added character? Thanks love the vid the new one about bed with the wig is great thanks again for all the info!!
Is it possible to spray clear finish over linseed oil to increase durability?
no respirator, spraying outdoors.aren't u worried about dust particles or maybe a tree branch falling on your work?
What i actually did was buy an easy-up, then tarp the sides, hang a light,a small vent fan on the ground and spray away. On some of the messier ones i have a tarp i lay on the ground so i dont ruin the concrete. Takes a few mins to set up, but keeps the spraying outside my shop and from landing everywhere.
12:51 . is that his backyard? it's massive!
For tip size: if I buy a 1.3mm good gun, I'm gonna be able to apply stain, water based sealer and varnish (Bona), and latex paints on wood? I wanna get the gravity fed Iwata W101 131G ... and also use it for my car and other small repairs around the house. I'm not doing this day in day out so I wanna get 1 gun and clean it thoroughly after each job.
Is it such a bad thing to use water and solvent paints in one gun?
You'll need a 1.8mm or larger tip for latex, but you can just buy the tip separately. I also like 1.5mm for everything else. I don't like to mix, but if your clean and keep your gun clean, you should be fine.
@@conleyhataway2618 Thanks Conley. Another confusion: I've been told that gravity gives bad results for latex because it takes too much reducer (20-30%) and it destroys the finish that way - and that pressure suction cups are the way to go because they don't need reducing that much. I don't have any experience - if I saw it in person I'd know right away - so how bad is it?
