Thanks for showing us how it’s done & especially for the links. One stop shop, so to speak. Much appreciated.
thank you, perfect no bs vid reinforcing what i was going to need to do for the project i'm working on.
Great video man! I followed your instructions to a T, my doors turned out great.
A lot of pro tips on this short video, thanks!
Awesome Video!!!!! Right to the point!!!! Perfect!!! No Stupid Irritating Music!!!!
Thank You So Much!!!!
Thanks for the video. I just broke down and bought a 3 turbine HVLP system so from what I can tell I won't need to reduce the paint this much. Problem with reducing the paint down so far is that is can actually change the color or tint of your paint.
That red stirrers are fantastic !! I have one.
SHORT AND INFORMATIVE "I like it" thank you, PATRICK.P
Very helpful, thanks for being straight forward
old painter here I have one of the old tube scoop measurers from sears from years ago, scoop out the diluted paint and time the emptying of the tube scoop, old guys rock
Thank you for the pointers!
Just what I needed to know. Thanks.!!!
Your explanation of how to thin latex to the proper consistency for spraying is golden. Thank you!
Not mentioned in the video but is very important: Follow the paint manufacturer's thinning recommendations. Zinsser says thin no more than 10% water (3 ounces per quart). Scuff-X and Advance are no more than 2 ounces per quart.
Most importantly, too much water has adverse implications for paint integrity, stain blocking, and final sheen.
[ps. I always measure my components before mixing so that I know what ratio works well and what doesn't. ]
Yeah and with materials such as MDF that are very porous (just like drywall), some people talk about expansion from the water happening in their experience. For painted rooms this is not as much of a concern, but with fresh drywall you would definitely not want to use too much water.
5 PERCENT IS BEST
Thank god....exactly what I needed♥️🇨🇦
Hey, that was very helpful. I haven't tried to spray latex before, so this was exactly what I needed. Thanks so much.
thanks man very simple and helpful
Thanks for the tips man👊🏽
You know, I first learned this 36 years ago on automotive lacquer and enamel paints, didn't know anyone else used the technique other than me and the old guy that showed it to me.
Big help! Thanks 🙏
great tip, Brian . . . just when I needed it, too :)
Thanks for this. Wish I watched it before attempting. My paint was way too thin and I had to sand it all off again.
Why could you not leave the paint on, then paint some more?
good video this helped. I have same gun harbor freight purple gun, I did the mod to that gun making the tip 2.0 from 1.4, only took 5 minutes to mod the gun for primer.
Thank you so much. Was alot of help
I use windshield washer fluid to thin down latex paints and it works great
have you tried using the washer fluid and water combo? Wondering how it comes out
Good video man. Viscosity is key to getting your hvlp working correctly.
Well I definatly have learned a new truck thank yiu
What kind of truck?
thanks that was very helpful i well tray it soon big hi from Egypt
This helped thank you bro
thanks for the quick straight to the point video, new sub from me
Thank you very much for the information.
Very good explanations .
Hey Brian crazy to see a video of your before the revolution!
Nice video, thank you and have a great day. 😊
U are the man very good and great job thanks allot for sharing
Cool thanks
I have been spraying automotive paint for years, but it never really occurred to me to spray latex with an HVLP gun. So I built a cabinet I needed for the basement, and figured I'd give it a try. I wasn't about to use my Sata or Tenka copper.... Those guns are over $600 each... So I used an old ass Harbor Freight purple gun that I had set aside for my old lady to use on her projects. I was actually pretty surprised at how well you can spray with properly thinned latex.... It works a lot better than my airless which always seems to gum up at the tip no matter what I do to the paint. Probably the only downfall is that you really need to take the gun completely apart and clean everything thoroughly. Then dry it and let everything sit before lube & reassembly.
But it works amazingly well. Far easier than spraying Lacquer or base coat. Any amateur can get nice results. Works great.
"It works a lot better than my airless which always seems to gum up at the tip no matter what I do to the paint."
Thats a common and really normal Problem. I go through 500 KG (roughly 1100 punds) of Paint a Day at work. The Airless System gums up at the tip all the Time. I need to put it into the cleaning apparatus several times a day just to get rid of that Problem.
Interestingly about 10 Years ago i worked in Asbestos Removal. And at the end you have to spray a Latex coating there too. To bidn the "leftover fibres". Problem we had back then was in the hight of tha tIndustrial Hall. And that no scaffolding was possible. So we sprayed that using an High Pressure Cleaner. Worked really well. But i wouldnt recommend it. We basically destroyed 2 before we had the right mixture.
I must have a bum HF gun. I watched this today and tried shooting some simple thinned ceiling paint ( the cheapest thinnest paint I own) its like painting with an airbrush at best... I cannot get the pattern nor the volume to work correctly...... and Id like to use this to paint my interior doors.
I tried at 40psi. 60psi etc... No luck. I get maybe a 2 inch spray pattern tops, nice and clean but it would take weeks to paint anything larger than a tv tray.
@@DHodges187 im not sure how your paint is thinned or at what pressure, but I sprayed thinned Valspar at 35 psi and it worked fantastic. I suppose it couldd be the gun... I always disassemble mine afyer every use and clean out everything especially the nozzle.
Sounds to me like the paint isnt thin enough yet. I used regular tap water but you can try windshield washer fluid too.
Will the latex lay as flat and smooth as lacquer?
@@zacschmelzer8487 I suppose it would matter what kind of gun you use, and what pressure. Ive sprayed lacquer and its easy to mess it up. I messed up a few things before I learned how to use it. This sprays easy. Try it on aome scrap first, but if you have everything set right and your thinned right the paint lays nice and flat. Very easy t9 do.
They actually make waterborne lacquers and paints designed for this application due to the demand for the most durable finish without all the harmful fumes. I have experimented thinning all types of paint to spray and almost always revert back to a basic rule. Use the right tool for the job so you only have to do it once. The video was great but it is better to use measuring containers in the process so you don't go past the manufacturer recommended thinning ratios for that particular project. Other than that i used this video to help me judge consistency. Ty!
Great video
The inline water filter is always great to have but not as big a deal with latex, if it were a oil base then most def use one. As for thinning latex paint and primer its not always a good idea to thin latex paint to much, some paints it will drastically shorten the life span plus other issues. Most latex paints shouldnt be thinned the same as oil based paints. Kilz and zinser primer's are designed to be used as is and can be thinned some, but over thinning will negate the effectiveness of the paint. You are using that cheap harbor freight gun that comes with a 1.3 or 1.4 mm fluid tip, that is not ideal for latex paint and primer. I wouldnt use anything less than a 1.8 to 2.0 mm fluid tip for latex unless the paint is specifically designed to be thinned that much.
I have always wanted to try painting my room with acrylic paint, using a 2.5mm nozzle.
Do you think it works?
thank you and Great video. Please show us advance paint viscosity for hvlp.
Old dog, new trick. Thanks from Colorado. Bark! Bark! Down boy.
So the 1.4mm fluid tip was sufficient to spray out thinned latex paint? Some people say that the tip should be drill to 2mm so that enough paint can flow. Thanks for the video and God Bless
Buen video! Thanks
Thanks bro
Thank Brian for the great video. I am new to this and this was very very helpful. 1 question, is this method good for all types of paints or just certain kinds?
Great!!!!
Good vid bro you should of mentioned stirring the can of primer before transferring into another can
Eh cause everything is sitting on bottom, all the solids lol.
I was thinking the same
@@waitemc 0p
I like to add a glug or two of Floetrol, it really helps during dry weather
I use the reg blue windshield wiper fluid to thin my latex to be shot through hvlp. seems to flow a little better then plain h2o
Nice. The paint should also slide off the surface of whatever you're painting a little better too.
Paints are constantly being changed and advanced every year. You really need to know everything put into that wiper fluid is compatible with the newer paints. That is a old timer trick that I dont think alot of knowledgeable professionals would tell you to go mixing into any latex paint you come across
i used the paint filter from hb to check the viscosity.
Gonna try this….thanks for the thinning tip. What nozzle are you using? I have a 1.8mm
So it's 1/3 h2o to 2/3 paint..try this on my garage this summer.
Hold the stir stick horizontal. When you get 7 drips in a row , your good.
So when using a viscosity cup once all the paint inside de cup goes down in 30-40 secs youre ready to go?
so no stream then? just drips? After the 7 drips does it stream? Does it stream before the 7 drips in a row and still be good to go?
will thinning with water effect the sheen? will the thinned satin still match the paint that wasn't thinned ?
Shouldn't you mix the paint in the original can first BEFORE pouring it into the mixing can?
Only if you want the color to match the paint chip. ;-)
@@JasonHoningford ...Paint chip?.....he's mixing primer.......
I was about to say the same
I thought the same too. Should always mix first so the ingredients are evenly mixed before adding water to any amount. Also, I would never mix into a dirty paint can (it had dried paint inside). It can contaminate your paint (I guess the filter would resolve that problem, but why create the problem to begin with).
@Moon Pie - Yes you're right. Sometimes you use what you have. I did see his comment about mixing before he shot the video after I wrote my comment.
Thanks for the video. Been trying to do this. Everytime i paint something. Just using behr latex paint. Its grity or rough finish. Is it to thick and needs to be thinned more?
I read somewhere on the internet a couple years back to use windshield washer fluid to thin latex paint for spraying. I've done it a couple times, and it's worked like a champ.
I like your viscosity test: quick and easy!
I use a 2.2 tip. No thinning required.
Been doing this for ages with my cheapo harbor freight screw on cup gun. I've even left paint in over night a few times and only had to take off the horn to clear the jam.. (15 mm socket to remove the brass horn inside the spray cap)
I spray cabinet doors with it at least once a week for the past few years. If it completely clogs up its $23 for a new gun..
So many of the cheap spray guns are labeled as HVLP when in fact they're just cheap knock off old style guns with a label on them.
Those HF cheapo's are pretty much bullet proof for latex. Just blow clean water through them and clean up the gunk in the cup when you're done.
I run at normal pressure although I probably could lower it a bit..
Go figure..The very same day I'm singing the praises of the cheapo HF spray gun the two I have decided to crap out on me. One started leaking really bad, the other has no fan adjustment at all and I have an order for 6 cabinet doors to get out this week.. oh well..whaddaya want for $23?
So what was that disposable paint brush for? Did I mis it?
Doesn't it make sense to mix the paint can before pouring paint into empty can?
Good advice. I've sprayed both lacquer and water based products and found that the "latex" paint was much harder to clean out of the gun than the lacquer. Do you recommend having a separate gun for each? I use LVLP for lacquer and it does real well. Do you think HVLP is better for latex (my broad term for water-based paints. I know they've got a lot of stuff in them that isn't latex.)
So that 6lb air compress worked ?
Thanks for the tip. About to use our HVLP for the first time. Which is better do you think, gravity feed or siphon?
Depends on what you want to do. I work in the Industrial field (Pylons, Punp Skid Units etc.).
Gravity Feed is great for almost everything. Constant flow of Paint and great ergonomic. But it has one disadvantage the siphon can do really great.
Lets say you want to take care of the underbody of an Car. You will stand below it and the way you hold the Pistole the gravity feed ones will only work for about half the cup they have. Because you have to spray upwards and hold it in a way that most of the Paint remains in it.
The siphon doesnt have that Problem. Thats why i took the underbody example. There are special underbody Pistols and they all are siphon ones.
Or an example from my Work. The Pump Skid Unit is basically a huge plattform for an Pump. On top and the sides the Gravity feed one works. But the underside? Thats basically 65 square Feet. Needing an 80µm primer (zinc Dust), an 80µm yellow and on top of that the 80µm gray the customers demand.
Gravity Feed makes me go crazy there. The back and forth is annoying.
Thank you so much I want to spray latex paint I just wanted to know how thin to get it. I do still need to get the air regulated for the spray gun and the water trap , paint filters, mixing cups then I'm ready to go.
Same here. I have everything except the compressor, paint gun, water separator, paint filter, air lines, air regulator, paint mixing cup, paint cup liners, paint stirrer and paint.
@@ChristopherJones16 Same here, plus I don’t have anything to paint.
Thank you how about oil based paint? Also I have a graco I habe. Graco truecoat 360 are recommending any tip nozzles for cabinet Finnishing ?
I’d already using Floetrol at the recommended 3:1 (paint to flo) ratio, would you still recommend 5-10% distilled water? Or just the Floetrol?
In my younger days we only paint latex to concrete. Is this the same thing?
It would be nice to know what size tip you have on the spray gun and, what air pressure you are spraying with.
Is the same procces with latex paint?
Mix the paint in the first bucket first so that when you pour into the next bucket all the settled solids come with it.
You are supposed to mix before you pour into the empty can to make sure your pigment is blended well. If you need more, it may be off color or thicker than you intended. Im sure you know this, just forgot to tell us.
Bingo! First thing I thought of. And I hate to paint.
That was primer, so color isn't an issue.
Love the opener.. they do make a lid opener for that purpose. .
i thought it was kind of comical. i figure if you need to be told you need a tool to open a can of paint then you are probably too stupid to use a spray gun....
Haven't tried that method yet, but may give it a go. I've been thinning latex paint (SW Emerald) with about 3 oz water per quart of paint, then I stir in about 1-2 ounces Floetrol. The Emerald dries like glass.
That is exactly what I do, use floetrol. I also have a "throw away" harbor freight gun drilled out to 2.0. It is just fine for latex, does a great job.
any of you two ever try using the windshield washer fluid with water and latex?
@@ChristopherJones16 poor guy has a dozen accounts and keeps posting the same dumb question over and over again! Let me help - no one will respond because it doesn't take a rocket scientist to know that windshield washer fluid is for cleaning glass - NOT - thinning paint! LMFAO - STOP - doing things just because you saw, heard, or was told to do it on the internet.
What pressure were you using in the video 40 psi? 60 psi? What size tip is recommended for latex in a gravity fed gun? Thx
I'm surprised you don't measure the water you're using. It seems that a lot of the new hybrid primer and paints only recommend diluting with 8-10 oz of water per gallon, max. Some don't advise any solution. I recently sprayed 80 cabinet doors with Smart Prime after diluting by 20% water in order to run through my HVLP and now I'm having adhesion issues. Seems like these new hybrids require airless sprayers instead of HVLP.
How about oil base primers? Can you spray them through HLVP gun using same method?
wouldnt you want to mix the paint before you poured it out of the gallon? how many solids did you leave behind?
Water huh? What about thinning duracoat? Will water work?
Never knew to use water to thin out a water based paint.
Your Amazon link is not the same color you are using ?
Should I filter the paint before I thin it??
thumbs up
Hi. What PSI do you set the air at?
Great information! Now, I'm going to guess that you use paint thinner with oil based paint? I'm also curious as to once you mix it if it stores well? I see that you're also using an expensive HF gun! Ha ha ha! Thanks for posting the video
Oil is so thin already i don't think you need to thin it.
The famous "Purple Gun" is a beast and still used by pro painters even today. Paint Society uses it
What psi/bar are you running your compressor on
Will that be good in car?
It would be best to mix the master can , paint only, and then pour it into your use can and add water, then remix.
You lost me when you left the heavier particles in the original can and then mixed the lighter/thinner material from the top of the can.
I mixed it up prior to the shoot. Guess I'll get it right next time! :)
You used the portercable 6gal pancake compressor?
How long can you paint for before it runs out of air. I was purchasing that to paint the hood of my car. Do you think it'd work out?
Linh Le how long is like asking how long a piece of string is. To paint a car hood 6gal should be ok. Bigger than that not so much.
@@bigpicturethinking5620 Lynn beat me to it. I was just looking at a 6-gallon Porter-Cable and paint setups at Harbor Freight the other day and they told me that anything less then something around a 20 gallon capacity would be a waste of time, so instead I bought the $30 electric gun. Actually wanted to paint the walls of a garage and so I just want to make it throw the maximum amount of paint, but if I could have done it with the 6 gallon pancake I would have sunk a whole bunch of money that day into air-powered tools, so perhaps it's just as well.
I used a sprayer for the first time today. Added water tonthin it out. Sprayed the wall and a 1000 runs. Wasnt happy. Out came the roller quickly. Any tips
How scout oil based paint
You used water to thin the paint? I thought that was not a good option because it breaks down the paints medium and affects the quality if the paint?
What would you thin water-based paints with then?
I am private labelling blank circular blades, I have a small air brush gun, WHAT is the best kind of Paint to use? I'm searching and thus far this is the closest I've gotten. When I first brainiac'd this idea, I used just spray paint to get an idea, however fingerprints were left, it's like it never dried, hence my request fo you guys. ANY advice would be appreciated, sincerely.
Shouldn't you have mixed the primer up before pouring it into the empty can? Otherwise, you leave the settled portion crucial for a proper mix remaining in the original can.
Exactly!
Shouldn't you have mixed it before you poured it in the other bucket?
But doesn't it matter what type of stage your turbine is ? I stage 5 turbine can spray thicker paint then a 1 stage turbine ?
Is it the same principle for all type of paient, oil based as example?
No you can't mix water into oil paint. Its why you need to use paint thinner to clean your brushes when using oil. Also oil is much much thinner already so if you thin it much more it will be like trying to spray water and expecting it not to run and drip
1/2 pint of water for gallon of paint with primer!!
