How to: Quickly Thin Paint to Spray Through a HVLP Gun 

I have always wanted to try painting my room with acrylic paint, using a 2.5mm nozzle. Do you think it works?

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

Eh cause everything is sitting on bottom, all the solids lol.

I was thinking the same

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.

I mixed it up prior to the shoot. Guess I'll get it right next time! :)

Why could you not leave the paint on, then paint some more?

Exactly!

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

What would you thin water-based paints with then?

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

have you tried using the washer fluid and water combo? Wondering how it comes out

@@ChristopherJones16 Washer fulid is already mostly water.

I prefer acetone with a tbsp of Japan dryer. It dries quicker than mineral spirits.

robert merrill thank u for the suggestion

Its better when wanting a perfect finish and running it through a hvlp sprayer

"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.

athhud he was mixing primer buddy.

It is water based so no problem there you don't want water in one big particle or not mixed in with paint

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?

Water won't work with oil-based paints

Evil Kermit says "put the water in the oil-based paint"

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.

Bingo! First thing I thought of. And I hate to paint.

That was primer, so color isn't an issue.

Because Amazon associated links give him a kickback if people but from his link

Because more then one place sells shit........

Extreme Works 🤣

That sweet sweet affiliate doll hairs.

Because there are not harbor freight stores every where and if you order from harbor freight online they charge high for shipping..

“should have”….

Thats an Imperial Dribble sir. :)

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.

Trying to keep it simple. Most people don't have a viscosity cup, like myself.

Small investment from Amazon so that you get repeatable results. For 10 bucks or less for the plastic ones. If you are spraying every day, may not need one, but if it's been a while, hard to remember exactly what the dribble is supposed to look like. Or, grab a small measuring cup from the kitchen, and drill a hole in it. As long as you are using the same cup all the time for your measurement, it doesn't have to conform to any particular standard.

@@moderndiy3290 plastic measuring cup from the Dollar store works.

Water for waterbased paints and primers. Paint thinner for solvent based.

@@toyotrustPR ok thank you

Or thinners..

You sure you mean Paint thinner? When using oil based Paint you need Paint thinner to clean your brushes. There are products like flotrol for latex paints but never can you mix paint thinner
