How to thin Acrylic Craft paint for spraying
« on: May 18, 2017, 12:10:34 am »
This may have already been posted, if so my apologies

Some people just use water, but I got this formula off the web that works well-

4oz of water (distilled if available)
4oz of Windex
1oz of Rubbing Alcohol

Put the above in its own bottle.  When ready to spray mix the thinning solution and paint in a 50/50 mix, stir it up good until you get an even consistency like milk.

Some people add a couple drops of Future or Pledge floor wax and claim that makes the paint dry harder, but I haven't tried this yet.

The advantages of acrylic craft paints are the price and they come in a wide variety of colors.  If you can't find a color you need, it's cheap and easy to make your own color.  Also you don't have to wait for shipping or pay shipping costs.

Have you every added Future or Pledge?  Not sure I want to spray that through my gun.

Yes I have it does work. I spray Future through my air brush all the time.
It is acrylic. Cleans up well with Windex.

The thinning method works great but I never tried the Future or Pledge trick.  How many drops do you add to the thinned paint mix?

Have you ever sprayed it as a protective clear coat?

I put about 4 drops to about one ounce of thinned paint.
It does make the craft paint more durable. You can also use
Automotive Windshield washer fluid in place of the windex
you can get a gallon of that for the same price as a small
bottle of windex.

And yes I use future as a finish coat on car models to give
them a high gloss finish. It also makes the windows clearer.
Just don't get it too thick or fine cracks in the finish will form
over time. If they do you can spray it again with a light coat
and they will go away for a while.

I usually use branded products for painting, maybe its snobbiness but meh! So I don't really have anything to add here, the formula you added looks interesting though, and Tankton's additions also.

I have moved away from using Future/Pledge myself cause I can never tell if its the right formula version I am buying, but I have used it in the past and it never had any nasty side effects on my Airbrush, so I wouldn't worry about shooting it through neat if you need to, just be sure to pull some warm water with dishwashing soap through the gun after you spray and before the polish cures.

Back when I was doing models years and years ago I also used model specific paint too, but now there are no hobby stores anywhere near me.  It's a pain waiting for things to be shipped, and by the time you add in shipping costs it sometimes doubles the cost of the paint.  That's why I started looking for alternative options.

I thin acrylics by 'feel', or actually more by look.  I use a solution of 75% water and 25% alcohol, using that to thin acrylics by texture.  I thin then spray until the mix is useful.  Not terribly helpful I know, but the AB is a finicky beast.
