Perfect Thinner for Acrylic Paint

Thought of sharing with you guys what I use to thin my acrylic paint with.

I use window cleaner, like Windex.

Use it on Testors, Tamiya, and on craft paint as well.

Works great, even better than the expensive specific thinners, AND it's a lot cheaper.

Problem is It is expensive. I use Windshield washer fluid. Here is a video I did showing some cheap alternatives and also a video showing how to use some of it. It is a great tip. Thanks for sharing.

Agree with you.

Here in Brazil, Windex is cheaper than windshield washer fluid.

In the U.S. you can find windshield washer fluid in big quantities, here we can find it only in 500ml bottles, as people don't have the culture of using a specific product.

Even on the cars owner's manuals they recommend to use "a few drops of household dish washing detergent" on the windshield washer bag and fill it with clean water!!!!

Remember there is no need for the windshield washing fluid to be freezing resistant here. Thus Windex being cheaper.

Ah, I apologize Tulio. I naturally assume people on here are from the states here. I am also not accustomed to your customs either. Windex would be the better solution in your case. I hope that the video's may have shed a little light on some of the ways to use them are. such as Windex is a great brush cleaner for when you hand paint acrylics. Baby wipes for keeping hands clean and yes Windex in your case is great for thinning but also the best way to clean your airbrush. One thing I will point out that windex has ammonia in it and will eat the seals in an airbrush if you let it soak in it. Besides that wiping it down and cleaning the needle it is GREAT stuff.

Yes, I know about the ammonia, but I never let the airbrush to soak, or at least never had to, as I always do the cleaning ASAP.

Since I saw your first video on acrylics and future tips, O bought some craft acrylic paint. The better brand here is Acrilex. It costs the equivalent to 90 cents a bottle of 1,25 OZ. Did some tests, and it performs as well as Testors or Tamiya. I'm predicting big savings here and have you to thank for them!!!

Does the blue color of Windex or windshield cleaner effect the paint? Seems like it would.

The blue color has no effect at all. Not sure why but I thin my clear polyurethane with it and no hue at all.

Around here we have the clear version of Vidrex (your Windex in the U.S.) but it costs more, and I have no idea why, and the regular product never interfered with the color of the paint at all, just like Chris said.

I say go for what is cheaper, window cleaner or windshield washer fluid, and never bother about the blue tint on it.

Use any of them with confidence, they won't affect your paint.

I tape off acrylics all the time. Just need to use a low tac painters tape or Tamiyal hobby tape. Masking tape is way to tacky and dries onto the paint allowing the paint to pull off. One thing that will help prevent the masking tape to pull is put a layer of gloss clear on then tape and don't burnish it down real hard. Instead, put another thin layer of clear down over the tape. This will seal the edges of the tape and keep the next color from bleeding under. If anything does bleed under then it will be clear and when you put on your main clear coat it will hide any clear as it is clear.

not all acrylics play well with windex/washer fluid.

"acrylic" is a category of paints containing dozens of formulations.

This is good to know. Can you please give names of brands so I can watch out for them? So far every brand of craft paints I have used I have not had any problems. I am sure AK, Comart or Vallejo are not good with washer fluid / windex as they are already pre mixed for the airbrush. Thanks for any info on this.

Thank you John. I have had no problems with yellowing. I have heard from some people that after like 20 years and left in sunlight they can go yellow but more people say thats not true that has used it for 50 years. My personal opinion on this is if you are a smoker and display your cars or leave them in direct sunlight would be the only way for them to yellow. Most of the people I talked to that claim they yellow were smokers in there home where they display. Any non smokers that use floor polish for 20 or more years have had no problems.

I had this problem only once. I did not primer the body before I shot the Acrylic. I learned that you need to have some adhesion to the body.

Masking tape is way too sticky. If you use low tac painting tape or Tamiya hobby masking tape it will not pull the paint up. Also with any tape if you put a clear or floor polish on before you tape it helps it come off as well. I tape and use all hobby acrylic paints for all aspects of my buil;ds and do two tones with no problem. If you use a high tac sticky masking tape it will pull paint off a wall. Switch tape and it will work just painting on the plastic.

im just getting into airbrushing and I know you can use the mop and shine for clear but can you use any other clears on acrylic or no due to the fact that is may react poorly

You can put enamel clear on acrylic. I used Crystal Clear by Rustoleum on many acrylic paints. I also use light coats of polyurethane on my acrylics. Not too sure how a lacquer based clear would do though. I am trying to stay away from chemicals. Really have no need to try anything else for my paint jobs. I do however, admit acrylics may not be the best for intricate pinstripe details as it may be too thick. That is where HOK comes in. But for one or two tone paints acrylics are great.

Considering that the active ingredient in Windex is ammonia, I wonder if just ordinary household ammonia would work the same way? Hmmmm?

Ammonia is not what breaks down the pigments. Windex just happens to have ammonia in it. Over here in the states I use windshield washer fluid that is ammonia free. It is just a glass cleaner. Ammonia is put into Windex to gut through and clean greasy fingerprints on glass windows. A quart of Windex costs $6.99 here in the states and a gallon of washer fluid costs $1.88. Some country's don't have the luxury of washer fluid or it is more expensive then Windex.
