thinning acrylics


Clark Propst
 

I’m in the process of building a trestle so my freight cars won’t get their wheels wet crossing a steam. It’s a Walther kit I’m modifying. I’m using the steel girder section and want to use MK Interactive products to weather it. They require an overcoat of acrylic paint. I had to run to Hobby Lobby for a 1/2 oz. bottle of flat black. The stuff is like soup. I added as much alcohol as I could pour into the bottle, but it didn’t help much. How do those who use such paints on their freight cars thin the stuff?

Clark,

Water (preferably distilled)…. never use alcohol, it leads to the paint drying too fast (like in the airbrush).  In the future, just buy a nice spray bomb of Model master flat black.  I even spray my brass models with it as a base coat.

Regards

Bruce

Clark,
I use two products from Liquitex. Both together for craft paints. 

Flow-Aid which increases flow and workability 
Airbrush Medium which thins the paint
Start with one part of Flow-Aid to 20 parts of Airbrus Medium

Clark as Bruce already said, "Never alcohol."  You did not specify the brand of paint you bought so I as George suggested use Liquitex Airbrush Medium for thinning.  It has worked well with various brands.

I’ve used 70% isopropanol to thin and reduce surface tension of Poly Scale in a ratio of 3 parts paint and 1 part isopropanol. I used my Paasche H with both #3 or #5 tips, depending upon the surface area to be painted. No clogs, no curdles, no errors.

The cheap "craft" acrylics are not easy to thin.  I use airbrush _cleaner_ to thin my acrylics for airbrushing, but I mostly use Polly Scale/Model Master and Accu/ModelFlex and those are already airbrush-ready or nearly so.

There was an article in RMC a few months back about the additives needed to make craft paints airbrushable.  Not home today so I can't look it up.

The Airbrush Medium is great as it does not alter the chemistry of the Acrylic Polymers. It can be usedto  thin Acrylic paint to create a wash for spraying with an airbrush for weathering. Isopropyl Alcohol is a great cleaner for Acrylic paint but will only speed drying, not something you want if the goal is to have the paint go on the model wet or to keep the paint flowing thru an airbrush.

Also most airbrush ready paints container RETARDER to slow the drying.
Not the same thing as thinner.

Clark another option: paint with your usual paints. Then overcoat with Future Floor Finish, which is a clear acrylic that sprays easily. The floor finish will give you the acrylic overcoat you need.

Guess I didn’t say I bought a 1/2 oz bottle of Model Master acrylic. These ‘additives’ you talk of? Are they available at Hobby Lobby? Closest hobby shop with a good paint selection is 2 1/2 hrs away.

Clark they may be.

Golden also has Airbrush Medium: Golden Airbrush Mediums - BLICK art materials

 Liquitex Airbrush Medium - BLICK art materials

I included the links so you know what to look for. Both of these companies are well known and respected in the artistic community. Dick Blick is a great source for things that can be used in painting and weathering. We now have one in Tampa.

Since there’s no hobby shop carrying model railroad inventory in my area, I’ve been ordering all of my model railroad supplies from HO Hobbies since Youngwood Model Railroad Supply closed. Bill gives a good discount (typically 25%) and the turnaround is pretty fast for in stock items if you use PayPal (longer if personal check, not credit cards). Of course, you have to plan ahead ; )

Thanks Bill! I see there’s a store in Iowa City – great for Nelson and two locations in the Twin Cities – closer to me.
I did see one in a shopping complex a couple miles up Naperville Rd from the Isle host hotel while we were eating at the Chilis nearby, but none of those I went to dinner with had heard of the place or had any interest in checking it out.

Although the Dick Blick store in Wheaton, presumably the one you refer to, is a great place to visit, they are also on line and advertise flat rate shipping.

I was going to suggest an artist supply store as a place for acrylic supplies. I use Liquitex airbrush thinner and a drop or two of their flow aid to thin acryic paint. Works well. Tony Wagner

Dick Blick carries PanPastel, colored pencils, and a variety of products useful for painting and weathering. While not freight car related, gauche is great for mortar effects in plastic brick. It comes in several mortar colors, and it’s the best product I’ve found yet for mortar lines. We have a store in Iowa City because the University of Iowa is located here, and the art department faculty and students are major customers.

Yes, there is a Dick Blick near our Lisle hotel. There is also one not difficult to get to in Saint Louis for those going to Collinsville RPM. I hit it last year coming from the airport. Their website is one of the best.

Clark, while there is not a Dick Blick’s store in Ames, there are several stores in Ames that carry art supplies, including the acrylic medium Bill mentioned. Liquitex has been around the for long time, I remember it from my college days. Have you check Hobby Lobby? They carry it. As does Jo-Ann Fabrics. Both of which are in the Mason City area. You have to think outside the box sometimes on this stuff.
