- Learn how to mix latex paint to be used with a spray gun. In this demonstration, we show how a thick latex primer is properly mixed to the right viscosity for an HVLP paint sprayer. The key is to use a viscosity cup and follow the instructions in the manual for your paint sprayer.
Here's a link to a viscosity cup - amzn.to/3d5gW3q

The first step to thin a finish is to know the type of finish you are using and what you need to thin it with. I use only water based paints in my woodshop, so I use clean water to thin the paint.
Next, you need to know how thick the finish should be for your paint gun. The thickness of the paint is called viscosity. To measure viscosity, you need a viscosity cup and a timer that measures seconds. The viscosity cup is dipped into the paint and then lifted out while timing how long it takes for the paint to change from a stream of liquid to the start of a drip. Your sprayer manual will tell you what measurement to use for the various types of finish.
For latex paint, I use clean water to mix the paint. Experience will tell you how much water to add, but start with a little at a time and measure the paint thickness with the viscosity cup until you get it to the right consistency as specified in your sprayer owner's manual. Ensure you mix the paint well after each addition of water.
Once you've got the right viscosity, you're ready to fire up the paint sprayer. That raises more questions for many people, so we're producing a series of videos to help you understand the aspects of spraying finishes for woodworking. In upcoming videos, you will learn how to make a compact, knock-down paint spraying booth for a small workshop. You will also learn about the difference in the air cap sets or tips used on paint sprayers. We'll also spray some clear finish to show you how to use an HVLP sprayer for your woodworking.

Great video, I’ve got an air compressor and spray gun I’ve never been brave enough to use because whenever I ask at the paint shop they just waffle on about “it depends what paint, what gun, what nozzle, what temperature blah blah”…… I just wanted to know the basic mechanics and this was perfect 👌🏼
Glad you found it helpful Nina. Cardboard is good to test on so you can see how your spray pattern is working. I always test my spray gun before spraying anything.
Lol me too. This is exactly why I'm watching. I bought them both years ago and still haven't used them. Time to add a new skill to the bag.
As a 65 year old HVLP spray paint beginner, I truly appreciate you making this and the other videos!
Thanks for your comment. That's encouraging. Scott
Excellent information. Thank you so much for actually demonstrating how it's done. I cant wait to watch the rest of the series!
Exactly what I was looking for. Thank You. Short sweet simple and straight to the point. Subbed.
The viscosity section was clear and easy to understand. Thank You!
Thanks for the feedback John! Scott
I certainly agree with your remark about there being nothing worse than watching paint flow. Thanks for speeding up those bits. But there is one thing worse, and that's watching paint dry! Thanks for your informative video.
My pleasure! Thanks for sharing your thoughts! Scott
Thank you for the video!! After reading my manual I was very confused about viscosity cup and drip times. This helped so much!
That's great! Thanks for sharing your thoughts. Scott
Brief and very informative lesson that has helped me immensely. ...... much love from Northern Ireland

Great video! Very helpful!
Thank you for your comment. It's nice to hear it's helpful. Scott
Ahhhh ThankYou kindly
A quick video. Easy to follow.
You're welcome!
I don't normally paint my projects, mostly because I don't know how. Watching your videos has given me a basic understanding.
Maybe I'll give it a try. Thanks.
Hi Robert. Happy you found this useful. We plan on making a video for spraying clear finishes as well so you might want to keep an eye out for that one.
Painting is easy. Get comfortable with a hvlp spray gun and you'll get a much better finished project
When I initially saw & heard Scott, I was truly overwhelmed by his enthusiasm!
Most people like the calm approach to our videos. I hope you watch more. Scott

I appreciate your remarks Scott, regards.
Great video thanks
Fantastic informative video thanks
Glad you enjoyed it
Very helpful!
Excellent ! Thank you 😊
You're welcome. Scott
Fantastic video
Thanks! 😃
Thanks for this keep it up 👍
Great video 👍
Glad you enjoyed it
Very informative. Thanks! Have you ever regretted not getting the “4” version of the Fuji?
I looked everywhere for a video that made paint mixing this simple when I got my HVLP. I didn’t find it until 1-1/2 years later. Great info man!
Thanks Russell. I appreciate that. Scott
Make sure your compressor puts out enough CFM to operate your gun the wat it is supposed to. A lit of hvlp gunsvtake as much as 12cfm to atomize paint properly. If you do t push enough air volume its lime using a water hose to pa8nt. I use LVLP spray guns. They are found easily at amazon and other painting supply stores. And take a lot less air volume. 3cfm is what that require. So a medium size 33 gall8n tank. 120 volt compressor pushes plenty if air
I wish I could give this man a hundred thumbs up for this vid 👍🏾
Lol. Glad you like it! Scott
very well said
Thank you!
Thanks for sharing.The drip cup method you use is more precise than some other methods. What size nozzle do you typically use for the latex paint? Do you have another video for the nozzle that works best for latex? In your opinion what is a durable latex brand?
Here's a link to a video showing tip/nozzle/air cap set testing with 2 latex paints - th-cam.com/video/AGof3BywLvg/w-d-xo.html
I prefer Benjamin Moore Advance paint. It levels out well and you can see how great it looks in the test video
Very good, thank you
You're welcome. Happy you liked it! Scott
Great tips!! Can you show how to properly clean your help gun after you have sprayed latex paint? Thanks
Woooooowwwww. I just got my paint gun delivered, and was so confused by that chart and it having seconds... I totally understand it now😅
That's awesome! Thanks for sharing that! Scott
The answer that I sought!
Excellent! Glad it helped! Scott
Really enjoy your vids! Please keep them coming. I have a question: I am going to paint our cabinets white, and purchased the mini-mite 5 and a 1.8mm nozzle set. I am going to use Stix and BM Advance. I decided on a 5 stage to give me a better chance at a pro finish without having to thin my paint much. I have read claims that a 5 stage can handle the BM Advance straight up, do you have any thoughts on this? Should I plan on thinning a little bit?
Hi Jim. I suggest testing it. I recently did some paint testing and it will be worth your effort to get it right. You bought some quality equipment, so try it out before you commit to all your cabinets. I know it can be exciting to want to jump right in with a new tool, but like most things in woodworking, patience usually pays off. Here's a video of testing 2 different paints and 3 different air cap sets. th-cam.com/video/AGof3BywLvg/w-d-xo.html Let me know if you have any further questions.
Also, thanks for the encouraging words. I've been feeling spread thin lately and your feedback gave me the shot in the arm I needed. Thank you!
I love it
Thanks! Scott
Great videos. Very easy follow and understand and the tips provided are very useful to me as one who is just getting into spray painting. I do have a question about viscosity.
It seems that most latex paints I have used recommend no more than 8 oz of water per gallon as a thinner. I cant get close to the recommended runout times without going well beyond that manufacturer limit. Warnings are that exceeding manufacturers recommended limits may cause the paint to become structurally unstable.
If they paint is still too thick when recommended max thinning has been reached ... do you just need a larger needle / fluid valve / aircap or do you just continue to thin?
In my experience and learning from a professional finisher, I ignore the label and thin to the proper viscosity. My preferred paint is Benjamin Moore Advance as it levels out really well when drying. I hope that helps. Scott
Question can u do a video on what dmt stone to buy for sharping chisal and card scapper
thanks man!
You're welcome!
Perfect could do one for epoxy paints or is polyurethanes the same
nice video
I’ve read in certain forums it isn’t ideally to mix and thin paint for a siphon fed sprayer but this seems to work great 👍👍 look forward to trying. Any tips for cleaning out your equipment? My old foreman used to just run thinner through until it came out clear lol
For cleaning, I use warm water and run a full container of water through the spray gun to clean the internal parts. If there's paint on the accessible parts, a stiff bristle brush works well. I hope that helps. Scott
Great series man the way you explain everything so simple to understand. I was looking for this information about how to dilute or what to use to dilute paint or primer and I've went thru several video but none mentioned what they used they just mixed and retested you actually if its water based use water. My sprayer says the information should be listed on the paint can but none of my paints mention anything about diluting solvents. I've had the machine for 3 weeks and haven't used it because I didn't want to destroy my machine in a single use or botch a job because I didn't know how to properly use my equipment. Thanks again for the information man your a great teacher much better then the commies teaching our kids today lol.
Nice!!
Thank you. Scott
What do I use to thin house pa8nt for interior walls. I use a 2mm tip on a lvlp gun. Not a typi, LVLP low volume low pressure. As my compressor puts out 6.9cfm at 40psi
Thank you!!!!
You're welcome!
thanks very much
You're welcome. Hope it was helpful. Scott
Can you use water on non-water based paints such as an acrylic paint? If yes, what is the difference to using paint thinner over just water?
Thank you.
Super, thanks. I painted cars 35+ years ago and now I’m trying to re-launch on HVLP and furniture. It’s reassuring to follow you through it. At least the drip cup hasn’t changed😀
I'm happy that helps. I guess there's some things that just can't be improved. Cheers.

Thank you.. 👍
Welcome 😊

Nice
Thanks
Great vidio I have a air compressor what paint would you say to use water base for my kitchen units
I suggest seeking advice from your local paint supplier for a paint that will work on kitchen cabinets and can provide a good quality finish when sprayed. Scott
Scott, you forgot to recommend an orifice size for your 30 to 40 second viscosity paint. I say use a 1.8 tikp. If you have 20 second paint go to a 1.3 or 1.4 tip. I got these numbers by testing paint I bought from Target Coatings. They had given me some tip sizes.
When I purchased my Fuji Spray system, it came with a viscosity cup. The manual provides target times for various types of finishes. I know there are several types of viscosity cups out there but I don't have the experience to recommend which one to use. If you do, please add a comment with the details for others to learn from. Thanks. Scott 🇨🇦
Thanks for this great video, very informative. I think I may have been diluting my paint a little too much. I have a 3 stage machine but annoyingly there's not listing for latex in the manual when it comes to viscosity just needle sizes. Have you ever tried Floetrol?
HI Ben. I haven't tried Floetrol. So far, water has worked well for thinning the finishes I use.
Nice Video! What Can I use to clean my Spray Gun?
Hi Thomas - cleaning a spray gun can be intimidating for someone who's new to it. Once you've done it a dozen times, it becomes routine. I only spray water-based finishes, so I use water to clean out the spray gun and occasionally use mineral spirits to do a final wipe of the paint cup. The key to an easy clean up is to do it immediately after you've used the spray gun. Once the finish starts to dry, the job becomes difficult.
Hello, thanks for the video! I have a few questions, I am not painting a home improvement project, but rather an electric guitar body. I don't have a controlled climate, but rather outside in which I must spray. The finish is Candy Apple Red that I am going for, so there are many layers, different colours and flake. I am on my 2nd last amount of spraying which is a self dyed red in a General Finishes water based clear coat, High Gloss.
1. How can I tell if my spraying and drying are going well or poorly?
2. How much do I have to sand until orange peel is no longer an issue?> all the way until there are no visible orange peel lines or just until they are knocked down?
That sounds like an interesting project. If you're getting an orange peel finish, you're not getting the best results. You need to change your spray settings and/or finish to get a smooth finish. Its best to practice on scrap material to fine tune your equipment, spray technique, and finish. When sanding down the orange peel, you should sand until it's smooth. I hope that helps. Scott
I'm thinking about purchasing a paint zoom pro machine ....to use with latex and oil based paint, I'm concerned with the oil based and how to clean the machine afterwards and what do you use to thin the paint when applying it to surfaces? Thanks
I avoid spraying anything other than water based finishes as you need to flush the spray gun when you clean it. I can't imagine doing that with chemicals. That's my opinion. Scott
It took me ages to find out the correct way to thin cellulose paint in the old days, nobody would tell me. Then I found an old Polish car sprayer that gladly explained that keep adding thinners to the paint, stirring, checking by lifting the stirrer, until the drips leaving the stirrer have no "tail", then, it was ready to use. That was in the 60's. Today, who knows, first "Two pack", now water based paints, probably with no instructions again!
Plz provide viscosity cup manual for different types of paints such as oil paints water based paints
There isn't a universal viscosity chart as it depends on your paint sprayer. You need to refer to your paint sprayer manual to determine the viscosity needs for what fluid you're spraying. I hope that helps. Scott
Thank you, I can not figure or find a video that explain how to mix the paint for a air gun.
I want to paint with lacquer on a dark blue. Can any paint be mixed with clear lacquer? Thank you
Please do not spray lacquer in a spray gun unless you have a professional spray booth. It is both highly toxic and highly flammable. The risks are too high for a non-professional to do this, which is why you likely can't find a video about this. Scott
i wanna spray Latex for gluing any info or help from your end ?
what dose the #4 mean on a Viscosity cup? are there different size?
Do viscosity requirements change depending in whether you are using gravity feed or siphon cup? Also, if you spray latex, do you prefer a larger orifice size and thicker paint, or thinner and smaller orifice?
Viscosity doesn't change for the type of spray gun cup. The purpose of the right viscosity is to properly atomize (spray) the paint.
For the air cap set (sometimes people call this tip size), I have tested 2 water based paints with 3 different size air cap sets. Both paints performed differently when thinned to the proper viscosity. Here's a link to the video th-cam.com/video/AGof3BywLvg/w-d-xo.html Based on my testing, latex paint intended for walls performs better with a larger air cap set.
Does that answer your questions?
It does, thank you!
I assume that there are correlations between fan pattern and size and pressure? More pressure for a larger pattern and thus, more paint?
I am looking at spraying the inverted hull of a 16' foot boat with high-quality latex (it's a trailered boat and will never sit in the water long. (The boat forums have a lot of positive references to using high-quality latex paints!). I have a 2.5mm HVLP gun arriving this weekend, and have a 27-gal/5 HP compressor available to me.
what percentage are you diluting your material? most say no more than 5% but in sure you are much over that is it ok?
Hi, first of all I apologize for my language but I do not speak English very well, I'm from Argentina and I like your videos. I would like to know what tip measure you used for water enamel, 1.5 mm or 2 mm. Gracias!
I would suggest 1.5mm as the paint is likely thinner. I hope that helps.
I have a question for you - would caption/words on the screen of a video be helpful for you as English is not your first language?
Thanks,
Scott
Can I apply this on metal as well?
Good advise one thing I've learned from experience is never mix paint in the cup for your sprayer use a separate clean container and strain the paint into the spray gun.
Thanks for your tip Peter. Your method would offer more efficiency for multiple applications - mix it once, and you're done! Thanks. Scott
Thanks for the great video. May be a stupid question but doesn’t thinning the paint force you to do more coats? I’m thinking of using a spraygun for a deck which usually takes thicker paint anyway. Last thing I want is a thin little layer of paint on the boards. :-)
That's a good question Jack. I mixed this paint for an HVLP sprayer, which is intended for fine finishing. Thin layers create a smooth finish. I wouldn't use an HVLP sprayer for a deck. I recommend an airless sprayer with is intended to put out a high volume of paint. This is what's used to paint house exteriors. The paint is typically used straight out of the can. Does that help? Scott
Home Improvement Woodworking sure does. Airless sprayers a bit out of budget. Looks like its roller time. Thanks for the reply.
Hi, are those viscosity cup times the same for each spray tips? Or would they be different?
There are different viscosity cups but they're not for different tips. They're for different sprayers. I use one cup for all the tips I use.
do you use tap water or distilled water?
Scott where would chalkpaint fall in these paints types, do you think?
I haven't sprayed chalk paint, but being a water based opaque finish, it's likely similar to a latex paint. If you're looking to spray it for the first time, try a test piece with 3 different viscosities so you can get a feel for it. You will quickly be able to see what works best for your setup. I hope that helps. Scott
Hi, i am using powehouse paint spray gun, it doesnt have any instructions in the manual on how many seconds should i use for the latex paint, should i use the 20-30 second for latex paint?
Give it a try on some scrap material and see how it works. If it's too thick, you will get an orange peel look to it. Here's a video showing different air cap sets and 2 different paints. You can see the difference in the finish - th-cam.com/video/AGof3BywLvg/w-d-xo.html
I used wood primer with oil already on my dresser. But I want to use deco paint. Can I spray deco paint on this dresser? Because somebody told me if I used wood primer so I need to go with oil base paint. What I should do?
I don't know what deco paint is. If it's a water-based/acrylic finish, that can't be applied over an oil-based finish. You will need a coat of something that will allow you to use a water-based finish. I recommend talking with someone where you buy your paint to find the right product for your situation - bring your paint cans to show them what you have. I hope that helps. Scott
Seriously who disliked this video. Smh. Thanks for the help!
What is the difference between the Cup on the bottom of the gun VS Cup on top of gun?
They both work well, but the gravity cup (on the top) gives you more flexibility when working in tight spaces. The siphon cup (on the bottom) holds more paint so you can cover more area when spraying. I hope that helps. Scott
@@HomeImprovementWoodworking ok great, thank you, great job
The ILVA 2K water based paint I am planning to use says to dilute with no more than 5-10% water, I believe. If that doesn't cut enough of the viscosity, do you just step up in tip size?
That makes sense to me. I've found it really requires experimentation to find what works right for each type of finish. Cheers. Scott
@@HomeImprovementWoodworking My question was that if one cannot cut beyond 10% water as suggested in your video, would the next move be orifice size of your spray tip? It sounds like that might be the case. For my specific purposes for the 2K polyurethane paint, warming it up by placing the can in a bucket of hot water for a while made all the difference in the world.
@@luke9822 I suggest following the manufacturer's suggestion in the instructions. If they recommend a specific viscosity, you should follow that advice. Changing the orifice size will not change how the spray gun was designed to work. I've thinned paint beyond the 10% point without issues for Benjamin Moore paint, but it may be different with other finishes. Here's a demo I did using different spray tips - th-cam.com/video/AGof3BywLvg/w-d-xo.html
Question. Does thinning the paint that much lower the quality or durability?
It doesn't in my personal experience with the finished I use, but that's not a generalization I would apply to every finish. I recommend buying the highest quality finish you can afford as quality makes a difference.
Will this still apply with custom mixed paint with primer in it?
I don't suggest using a paint with a primer in it... I could be wrong, but it seems like a "marketing" trick to get people to buy a product like that. You need a primer on bare wood. You apply a quality paint after the primer. That's my advice. Scott
So for fence paint it says undiluted. Does that mean, do not mix it with water no matter how thick it looks?
If you're using a paint sprayer for a fence, you're likely using a different type of paint sprayer. Follow the instructions in your manual.
What guide do you use for paint+primer?
Sorry, I don't understand your question. Are you asking if I like using paints that are branded a paint and a primer all in one? If so, my answer is no. Primer has a separate function than paint, and one product can't effectively do 2 different jobs. I hope that helps. Scott
did you add water in paint before painting the object?
Yes, that's what this video is about
Sir water maxing in paint which paint is that please tell us
Water-based paint is referred to as latex or acrylic. I prefer to use Benjamin Moore Advance for spraying. Scott
“You got the drip” didn’t know you liked rap. Haha
Lol. that's funny
Is there a ratio that works??? Like 10:1 etc
If you mix the same paint repeatedly, you could work out a formula. There isn't one formula for every paint, which is why you need a viscosity cup. I hope that helps. Scott
Thank you! Works nice! But why am I still spitting paint?! No matter what I have done… 1.3 tip 1.8 tip, the paint still spits down it’s not a nice mist
You can use water on oil paint?
No, you need to use a solvent that works with the finish you're using
So latex paint should run around 20-30 secs?
No, you need to refer to the guide for your paint sprayer. I show my Fuji Spray manual, and what the paint viscosity needs to be. I hope that helps. Scott
Over heat problam
Can i use water based disinfectant in paint spray gun
I don't know for sure, but in theory it sounds like it would work. A spray gun is just atomizing liquid. I'd be careful though to understand what you're spraying and wear the proper respirator to protect your health. You might also do some damage to the spray gun parts - I'm not sure. Scott
