- This week I want to discuss spraying finishes. I always get asked if I like to spray my poly or other finishes. The answer is YES!!!! I LOVE IT!!! Since starting to spray, I wouldn't have it any other way.
In this video I share a couple of the guns I have used and some of the techniques that I like to us.
Hope you enjoy.

Thanks!
Great video but your excuse for not wearing a mask just does not cut it. We test and quantify exposure. Your exposure with an HVLP is significant as the aerosol is so fine. Ten or twenty years from now, you will have a far greater risk of having a chronic respiratory disease. You are not invincible. Not being able to breathe really is a terrible way to go. This is professional advice.
Craig Fourie thank you for the information.
I have a Wagner flexio sprayer. Any tips for settings when spraying poly? I feel like it sprays very heavy.
I don’t have any experience with one
I am going to spray oil base poly, do I need to thin it?
Just a quick tip; spray the edges first.
That's what I was thinking too. Thanks for confirming.
The homeright cant
Spray lacquer the
Rockler i like bettsr
I like my $20 HF Purple Gun.
I see in the comments other people were thinking the same thing I was. He's not wearing a mask! You spent the money on clamps and a spray gun but have you got yourself a mask yet? I hope so. Your lungs will thank you.
Excuse me....I have a question? Obviously your lawn mower is still orange...You didn't create a circus tent of plastic film before spraying, is over spray a concern? Does your mower have a nice polyurethane finish on it? Also, how long can material stay in the sprayer? Do you have to clean the gun between coats? Or can it live in the gun for a while? How much troll outrage did you have to endure for not wearing a nuclear radiation suit and WWII gas mask? 😁 I just bought a Fuji System and and gearing up for my first project. Thanks for the great video!
I don’t worry about overspray too much honestly, especially with a good spray system. HVLP is able to be dialed in to where overspray is minimal. This is an old video and I have a Apollo turbine and also a Fuji gun now. At most, I’ll drape some inexpensive plastic sheets on nearby tools. In an enclosed space I will wear a mask but sometimes if I’m in an open area with a lot of airflow I won’t. Which isn’t necessarily right, but it’s my choice. As for the trolls, no matter what I do they will come out 🤣🤣
@@bentswoodworking How about material time? In the gun/cup?
I concur on the overspray with the hvlp rockler, not much
When you spray oil based poly with the Rockler, which needle do you use? 1.,1.5,1.8,etc..?
In the rockler I have used only the tip that comes in the gun
So you don't use a mask????
Stephen Currie I do not, typically I am in a well ventilated area.
Bent's Woodworking "ALWAYS, ALWAYS, ALWAYS" wear a good quality mask that is appropriate for the chemistry of the product you are spraying. Urethane finishes are among the worst of the products you can spray without a mask or a hood using class D breathe air. Once they are inside your lung tissue they will harden just as if you you were spraying that tabletop, they will "never" be expelled, this will cause you too develop Emphysema...I doubt that you will believe my warning..."do the fu#king research yourself" , it will save your health.
Nice job! What do you do if you have bubbles? Because I sprayed a clear coat and see bubbles let it dry then sand it then spraying and bubbles again.
Hi Jason! Great video! I am about to stain and finish my front door. I see you suggested Oil stain in the comments and 36 hours. I was wondering about the spar urethane you also mentioned below. Is that also water based? Can you suggest a brand, please?
There are bother water and oil based spar urethanes. I like general finishes products
Hi what product you used and did u diluted anything. Also does this have a tip size I am planning to use hvlp gun which i use for cabinet painting
Thanks again for your videos. I’ve spent the last two weeks trying to lay down Endro-Var II on a walnut desktop with a brush. I’ve been holding off wanting to get a Fuji or Apollo system, but it’s just not in the cards right now. Just purchased this Rockler system hoping to get a finish that I’m happy with.
Glad you found it helpful
What size tip is important, I ordered 1.00 and 1.25 from rockler or Earlex
i dont think i heard or read if you use more poly by spraying it versus brushing it on,, also i know using brushes you get runs sometimes, do you get any runs using a sprayer..
You definitely will use more spraying then by brush. Yes you can get runs as well if you spray too much in a spot.
When you use your water based polyurethane do you dilute it a little bit or do you put it on full strength thank you sir
Great video !
Thank you for presentations. I love your indepth and work ethic you place in all your presentations.
Glad you like them!
I am having issues with spraying oil based poly (Minwax) over new stain (MInwax) . It looks great wet but It keeps drying up to a blotchy orange peel type finish (HORRIBLE). Any suggestions would be greatly appreciated.
Well I almost never used oil based poly. But, I would say the blotchy parts could be from the stain not being fully dry. There are some great videos out there on orange peel type finishes.
My question has to do with painting your shaker doors, for which you show using MDF for your panels. You mentioned priming before painting in one of your comments to a fellow You Tuber, using the Rockler sprayer. Have you found it necesry to spray any kind of sealer over the MDF first, as suggested by some other woodworking craftsman, or is the priming sufficient?? Enjoyed the video.
I have never sprayed any sealer over them. I have been happy with my results
Another way to spray a large surface like this table to insure even coating start at the middle of the table work toward yourself spraying to the edge. Go around they other side and spray that. Even overlap, even distance is critical.
Love the video, answered a lot of my questions. I am in a bit of a jam in that I am building a massive solid hickory dining room table and didn’t do my research beforehand. I already put a natural oil based stain on to darken it a tad and got a few splotches. I am wondering if I should cover with spraying oil poly or can I use lacquer to finish? Could you see the splotches through the protective layer?
You will definitely still see them. The only way to fix it would be to sand it back, then try using a conditioner before reapplying the stain. Some woods take stain worse than others.
Awesome video, thanks. I am looking at getting a spray gun.
When using polyurethane, oil based, do I need to dilute the poly or can it be used like that?
I have never thinned clear coat
I just switched from oil to water based varnish and it’s been a mess. It dries so fast as it sprays that it cakes up the tip of my needle, and within minutes it spits and bubbles. What should I do???
What type of sprayer are you using?
Thank you so much! Do you have to water down water based polyurethane for the spray gun?
Never
Thanks for this video - i have a Fuji spray system and cant seem to get the high gloss “mirror” finish i am aiming for - cant seem to get the mix of poly/air/application right. Any hints on how much to put on for that mirror finish
Thjanks
JackBrown 2962Drums I have never used the Fuji myself but would love too. As for the mirror like finish, again something I don’t do. Customers have never wanted anything that shiny. I know a lot of people buff finishes to make them very shiny.
When you do multiple coats in a day, do you clean the sprayer between each coat, or do you cheat and clean once at the end?
Dave, thank you for the question . If I am spraying multiple coats of polyurethane then no I will not clean the gun between coats. Since the coats are going on every two hours or so, nothing will harden inside of the gun. All I do is check the tip to make sure that no polyurethane is dried that will restrict the flow and that does happen from time to time. For just cleaning it in general once I am done spraying my coats I simply take it inside of the sink rinse it out with warm water and then I will take it back into my garage put a little bit of mineral spirits and it and fire the gun just to clean off the needle and internal parts. It's really that easy. Having to guns though makes it a lot better because I have one for my stain and paint and then one just for Polly. When cleaning the one for stains and pains it is a little bit more time-consuming just because of the product itself meaning the paint is thicker and stain is more oily. When I just had the one gun for everything I will be honest my cleaning practices did not exist and I was very bad about cleaning until I actually needed to use it but then the cleaning would take twice as long. Now that I have the second gun I'm a little bit better about it.
Thank you for replying.
Dave Erickson always!!!
Hey, masks are for Karens and Sheep. Strong work!!! How necessary is it to sand between coats?
Depends on the finish used
5:36 Are you using your tongue to test the moisture in the atmosphere? Thanks for these videos, I really enjoy them:-)
Lol
I am using water based poly for the first time on some walnut coasters. I used Varathane from the can and probably put on too much, but I was trying to get good coverage. After 4 hours the pieces are still sticky and have some runs. I wiped them down with a cloth. Any advice on how to remedy this situation? Can I sand with 400 grit as opposed to 220?
What were the conditions it was drying in? That can drastically affect curing
@@bentswoodworking They started out in my garage - for about the first 20 minutes. It was at about 45 degrees. I then brought them in the house.
I keep coming back to this video for my next project, my exterior door. Its my go to video for this project, all water based and spar urethane. Haven't decided which brand, but I see you like and get great results from General Finishes. I hope my garage doesn't get too much over spray, but I already see your comments below for that. You have the best videos Jason! Keep up the awesome work buddy! Oh, and I will be trying out the Wagner hlvp similar to the Rockler. Looking forward to the project with my son 😊
If I am not using Rubio Monocoat then General finishes is definitely my top choice.
What about using areosol can polyurethane on small peices 22×30
You can do that
Yes, i have a can of oil based minwax poly i want to try to spray using my smaller paint gun i use for small auto repair jobs and touch ups... if i need to thin since i will be spraying small projects using a small nozzle what do i reduce with??Thanks
I have never thinned anything but paint. Most guns won’t required poly to be thinned.
Beautiful job , I have the same sprayer from rockler, could you tell me what size tip did you have in your gun and what kind of finish did you use? Water base poly I heard what brand ? Any yellowing ? I have been spraying deft lacquer they say don’t spray on the can but it worked well so far . It did lift on a couple of spots what a pain don’t know why. .?? Thanks
wHERE IS YOUR MIXING PROPORTIONS
I have both the Rockler hvlp system and the new HomeRight spray gun. I have only used the Rockler system for paint which is a pain with having to thin the paint. The HomeRight gun is still in the box. I’m thinking of spraying both stain and poly for my current project. What gun would you prefer I use for both the stain and poly? Is one better for stain and another for poly? What size tip are you using when spraying your finish in this video? Thanks in advance.
Jophus1er I would tell you to dedicate the rockler for finishes in the Homeright for stains. But if you had to pick one to do both I would choose the rockler mainly because it is easier to clean in my opinion. As for the tip it’s just the one that comes with a gun.
I use a 2.25 for paint in rockler paint is thick works fine .
Thank you very much for the video btw.
You’re welcome
When using poly, do you clean the gun between coats? How long can you leave poly in the gun between coats?
No, I won’t empty the gun between coats. I have actually left it in the gun longer than I would like to admit 🤣
Have you ever had any problems with poly fish eyeing or orange peeling? And how did you deal with it? I could be wrong but it seems like if that was a major problem, sanding wouldn't be a very efficient solution, especially if applying 6-10 coats.
Teach people to wear a mask sir !!
Thanks for the video. Have you sprayed a top coat/poly over paint before? If so how long do you let the paint dry/cure before applying the poly? I’ve never found a clear answer for this.
I never spray poly over paint. Just a personal preference
Greetings, I was pleased to know that the paint gun is very good and the type of portable compressor you recommend, thank you very much
With the Rockler sprayer how much do you have to worry about overspray?
How hard is it to clean up oil based poly?
Do you need to thin down the oil based polyurethane?
Thank you
With any sprayer overspray is a concern. I never thin any finish other than paint. I never use oil based anymore actually
I understand overspray is always an issue but my workshop in small & I don't want to have everything sticky.
My work is mainly exterior signage do you think water based poly would last longterm outdoors?
Gary Wiant I wasn’t saying that to be rude. What you can do to help with it getting on other things in the shop is lay down a few of the very inexpensive paper painters tarps. As for something doing outside, I recommend you use a spar urethane and not a poly. Spar is what you would want to use for outside due to its UV protection
Yes I've been using Varathane Spar Polyurethane either via brush or rattle can. I love the finish of the rattle can but not the cost.
Over spray not a problem once you get the sprayer adjusted , I love it rockler , it also depends on how you are spraying at one time
Man that thing makes a ton of noise. Nice looking project though can't argue with results. You really should be wearing a respirator and goggles though
Really need to keep the gun perpendicular to the surface so the coat is even not heavy to one side of the pattern. Lots of different techniques, spraying closer moving faster or further away like you are doing and going slower, just what ever works for you, but that-gun angle is always perpendicular to the surface. Automotive painter for 37 years here just so you know. Thanks for the tips.
Hi sir
dude, wear a respirator with that crap
No grain raise with water base? I have a big job coming up and im debating oil vs water base. I’m probably going with conversion varnish for the durability … but didn’t realize i needed to use a vinyl sealer after the stain and before the top coat
So when you do multiple coats of paint, do you sand them in between if yes, what grit do you recommend?
Danish Qamar I usually do a prime coat and these sand with 220 then spray the remaining coats only sanding as needed.
Great job explaining everything thank you
Glad you found it helpful
Did you use yellow pine on the table? What stain did you use?
Oak, and I can’t remember the stain but it may be in the video
Hi thanks for the great video. I didn't pick up whether you're mostly using water based material. Using NON water based, do you think the Homeright gun works any different in coating/spraying or is probably more suitable for water based? Thanks
Mostly water based but I don’t thin either in any sprayer. The only thing I have had to thin is paint.
I sprayed my paint with 2.25 tip never thinned my paint, works fine so far
hello, I was wondering if you could link the top coat that you recommend for a kitchen table
www.woodcraft.com/products/hp-polyurethane-top-coat-gloss-quart?via=5d112bea776f6f4e030006e2%2C5d112e45776f6f2c7b000622%2C5d113334776f6f393e000ccd would this work?
That’s a great finish
Can I use spray gun with poly stain all in one?
I don’t see why not, but I have never tried it myself.
Do you recommend spraying Minwax Helmsman spar urethane? If so do you thin it?
I’ve sprayed that plenty times and it’s great. I never thin finishes and never had any issues.
@@bentswoodworking You mention that the final spray is a very thin one. Do you mean it's a light coat or that you thinned the poly? The reply here makes me think it is the former.
David Masterman a thin coat. I never thin polyurethane
With the Rockleer system have you used any oil blends like Arm r Seal, Waterloo, etc. and if so how are the results???? Thank you, so glad I found your channel I’ve been following on IG.
Thom spillane thanks for the follow and question. I have sprayed only poly in the Rockler system. Both oil and water based with excellent results. I usually use water based due to dry time and lack of color change. I have used paint in the Homeright and that is the only product that required thinning. Also excellent results. I will only spray paint finishes now regardless of how small the project is. Hope that helps!!
Bent's Woodworking Thank You I appreciate the information.
Thom spillane no problem at all. I'm always here if you have any questions!
Great video. I have a home right sprayer and was looking for info on it. Exactly what I was looking for. When it comes to using stain on projects, do you ever find you have to go back and wipe off stain that hasn't fully soaked into the wood after you sprayed it? Thanks.
Heath Hensgens I have to do that Regardless of how I applied it.
I spray it on and wipe off depending on how dark you want it to be. Don’t wait to long you will have a mess 😢
Do you spray any lacquers at all ?
Pigmented lacquer yes
When you apply Polycrylic with your spray gun, do you dilute it?
I do not.
whats the pressure at? Seems like its blasting pretty hard
What’s the tip size in the rockler?
I believe it’s a 1.0 but I’m not certain off hand. I also believe it came with a extra size
Thanks Jason. I’ve been starting out spraying a bit, and the clear finishes seem to work well - but the cheap sprayers don’t handle the latex paints well at all.
No Mask?
Not here no
When spraying try keeping your gun parallel to your work piece, this will insure a nice even coat
Thanks 👍
I love the way your table top looks in the stained mode. Would you be able to describe or show how you apply the stain with a spray process?
great! is just what I need!
Glad you liked it!
Great content, very helpful
Thank you!
Great video
Thank you
What kind of poly do u use? Nice video!
If I am using polyurethane, I prefer General Finishes
@@bentswoodworking is there ever a need to thin Poly? If so how do you tell and what do you use?
@@bentswoodworking
Oil or water? It's good to be clear about which one.
You didn't say anything about % of diluting poly or with what did you dilute poly with?
BIG JOE 245 I don’t dilute poly. There is no need with the sprayer. Paint does require thinning though
So what ratio do you use when you use paint !!!!!
Stephen Currie with paint, they do require thinning with water. The homeright comes with a piece that is used to check the viscosity of the paint. It's a timed thing. After a few times, I was able to eyeball it. It's a very simple system. Stain and poly require no thinning at all.
To give you an idea for a full container, it would be 80-85% paint, 15-20 water.
When use water based poly, do you use water based stain. Can you put water based poly successfully over an oil based stain.
James Tollett great question. I almost always end up using oil based stain. It’s no problem mixing the two as long as you let the stain fully dry. I am usually overly safe on dry times. If the manufacturers recommendation is 24 hours, I will do 36. Hope that helps!
Bent's Woodworking Thank you for quick reply. If you have a chance to make a video on spraying stain I know it would help me and probably many more people. So glad I found your channel. You explain things very well.
James Tollett thank you Sir. I can look at doing something like that when I return from Ft Knox. What I can tell you now though is that spraying stain is even easier. You literally spray it on and then just wipe down all the excess. Downsides is it definitely makes a mess and you really need a nice, big open area. Typically I will only spray stain if I have multiple large pieces being stained the same color.
When using water base poly do u thin it out with water
Bearded Locos DIY never. Regardless of application
Great video. What type of polyurethane do you use with your spray gun?
Brady Apostolo I pretty much always use water based poly. My favorite brand is General finishes
@@bentswoodworking. Hey, Thanks for the reply. I've heard great things about General Finishes.
Brady Apostolo if I use stains or poly they are my go to!
Fine video, but you really don't explain "how" but spend most of your time discussing "should" you spray finishes.
I suggest you update the title to reflect that.
