Tamiya Paint retarder - Great for brush painting Tamiya acrylics!
Posted by bluenote on Monday, October 01, 2018 9:11 AM

My usual painting technique is to use Tamiya acrylics for airbrushing and their enamels (imported from Japan) for brush painting.

I recently discovered Tamiya paint retarder and thought I'd try it out.  I used Tamiya acrylics and put a couple of drops of paint in a pallette, and added 1 drop of Tamiya retarder.  It works great!  I used it with flat black, gold leaf, chrome silver and metallic gray and painted on plastic spoons.   All colours went on very nicely.  Chrome silver and gold leaf needed a second coat, but the other 2 were fine without a second.  There was no pulling up when I applied the 2nd coat, and it basically went on much like an enamel would.  It levels perfectly.  The only downside is it takes a while to dry. 

For those who have given up on brush painting Tamiya acrylic, I would highly recommend you try their retarder.  It's dead easy, just add 1 drop to a couple of drops of paint.  That's it. 

I will no longer import their enamel paints, as this works just as well.

Anyone else have good success with this?

Not with just the retarder, at least so far; I keep meaning to try it. But their X-20A thinner is said to have retarder in it as well, and I've had good success brush-painting their acrylics that way.

That said, I shall give the other a try soon. Thanks for posting your experience

I second Blue’s comment.  Makes brush painting Tamiya’s paint so much easier.

On the workbench: 1/35 Takom T-54B; 1/35 Tamiya Char B1bis w/French Infantry; 1/48 Tamiya Fairey Swordfish Mk. 1

It does help with brush painting.

The directions on the bottle of retarder say to not add more than 10% to your paint. I mix my retarder into their X-20A thinner at about an 80/20 ratio, then I use that mixture with their acrylic paint at about 50/50 for airbrushing. But if you are happy with your ratio, I won't tell you to stop.

And yes, Tamiya acrylic paint/thinner already has some retarder in it, but sometimes more helps.

I too tried some of the retarder and was pleasantly surprised at how well it worked!  I was the same way...I AB'd with Tamiya acrylics and usually used Testor enamels for hand brushing.  But the retarder worked well with the acrylics and now I just mix that up when needed.
