Zamtro Posted May 28, 2017 Share Posted May 28, 2017 Howdy, I'll preface this by saying that there is a lot of information to be gained from google and many tutorials regarding Decanting Spray Paints. The problem I'm having (or possibly having) is that virtually every tutorial specifically talks about using the decanted paint in an air brush. I don't own and air brush, and don't intend on buying one (I'm a simple man) but the spray colours I'm wanting to use only come in a can. My issue is that I will 100% guarantee that I'll need to touch up some spots from over painting other parts of my marines etc. If I was to decant a can of paint, and use a brush to apply it - are there any additives to add? (Stop the paint from drying on the brush quickly or whatever) Most tutorials say let it degas overnight (or a few hours at least) - will this form a skin or require a thinner to be added after? Hints/tips to not ruin my brushes when using decanted paint? I've also seen that using Decanted paint on an area that has been previously sprayed with the original colour can cause issues - any advice? It would be lovely if the paint I wanted to use came in a pot too... but of course it does not. I did do a search of the forums but didn't find what I was hoping for.

Imren Posted May 29, 2017 Share Posted May 29, 2017 If the paint to be decanted is water based acrylics, Then you can mix in Vallejo paint retarder and also thin it with either water or Lahmian medium or Vallejo thinner. I suggest you decant it into dropper bottles to minimize dried flakes, and skin issues. Dropper bottles have less contact area with air due to smaller opening compared to pots. If your paint is alcohol/hydrocarbon based acrylics, such as Tamiya, then use Tamiya 87114 paint retarder as retarder and X20A as thinner. But keep in mind to avoid using sable hair brushes with Tamiya acrylics, the paint will spoil the sensitive sable hair brushes. I'd recommend you to use synthetic brushes only. If the paint is enamel type, then you need to use the manufacturer's recommended retarder and thinner (perhaps white spirit will work as thinner?). Tamiya paints works fine airbrushed over Vallejo's acrylic waterbased primer, but I don't know about applying Tamiya acrylics over water based acrylics regular paint, If I were you I'd try it on a piece of sprue before and see if it works. If it does not work then apply a coat of matt varnish on the water based acrylic painted surface before applying Tamiya.

Cheers and good luck Thank you, the paint is a Tamiya TS (The paint is a synthetic lacquer that cures in a short period of time) So I will use the Tamiya Thinner/retarder recommended! Thank you for the help, it is much appreciated! I'll pick up a synthetic brush too. Champion!

Imren Posted May 30, 2017 Share Posted May 30, 2017 The thing is, tamiya acrylics have alcohol/hydrocoarbons as medium and use the mentioned retarder (that retarder is made for tamiya acrylics). You mention you'll use Tamiya TS-line lacquer paints. And for these Tamiya seems not to have a retarder. Have a look at these pages: info about TS line: https://www.tamiyausa.com/items/paints-amp-finishes-60/spray-ts-(plastics)-61500 Check out this page, they seems like this retarder called Mr Hobby paint retader might work with Tamiya TS line (lacuer paint): http://www.armorama.com/modules.php?op=modload&name=SquawkBox&file=index&req=viewtopic&topic_id=210753&page=1 Bottom line: the Tamiya products I mentioned works with Tamiya acrylics with that are alcohol based (X and XF line), and might not work with the Tamiya lacquers (TS line) Link to comment https://bolterandchainsword.com/topic/333985-decanting-tamiya-paints-to-brush-on/#findComment-4761473 Share on other sites More sharing options...

Edit: found a shop nearbyish that sells the Mr Retarder. Not sure how long before I'll actually get to start this project but I'm hoping to one day update with pictures - You've been a huge help!

Brother-Chaplain Kage Posted May 30, 2017 Share Posted May 30, 2017 If you don't have a respirator and plan on using lacquer-based paints and thinner, get one. And I don't mean the cheap little paper mask that covers your nose and mouth and has a couple of rubber bands stapled to it because those are worthless. Spend the 50 bucks or so to get a decent quality respirator because those fumes are bad news and decanting is going to atomize that stuff and you can never contain all of it.

Imren Posted May 31, 2017 Share Posted May 31, 2017 Yes, and also consider doing the decanting outdoors, preferably on a windy day. Link to comment https://bolterandchainsword.com/topic/333985-decanting-tamiya-paints-to-brush-on/#findComment-4762654 Share on other sites More sharing options...

And will definitely be doing this outside!
