cruiserguy Posted September 17, 2014 Share Posted September 17, 2014 Hi Everyone, We all know Vallejo paint can be a bit fragile. I came across this comment on YouTube from a guy called Strangetonic who was commenting on a Coat D' Arms review: To make Vallejo paints more resistant to chipping and peeling, mix in a small amount of Golden GAC 200 medium. Try about 3 or 4 parts Vallejo to 1 part GAC 200. You can use this to make any other acrylic paint more durable too, including Coat D'Arms. Also, acrylic paint takes about 3 days to reach its final level of hardness, so be careful with it until then, even if it seems dry to the touch. I haven't tried it yet myself, but it might be worth trying if you have problems with paint durability. However, check the info on the Goldn site about this medium. It appears if you use to much the paint might crack Best Wishes, Will. edited to make the comment clearer 17/09/2014 - 17.09 4 Link to comment Share on other sites More sharing options...
robvulcan Posted September 17, 2014 Share Posted September 17, 2014 This looks interesting if it does indeed make paint tougher. I will check it out. Wonder how not works ! Cheers Rob Link to comment Share on other sites More sharing options...
cruiserguy Posted September 18, 2014 Author Share Posted September 18, 2014 Hi Rob, I posted because I love using Vallejo paints but have found them prone wear for a few days. I honestly don't know how the Golden stuff works. I can only guess it might be some kind of hard-wearing acrylic polymer. A while ago I had wondered whether adding a little Klear to Vallejo would toughen it up a bit, but didn't get round to trying it. As for the Golden 200 medium, it might be work checking Golden's website for more info on it. Best Wishes, Will. 1 Link to comment Share on other sites More sharing options...
bootneck Posted September 18, 2014 Share Posted September 18, 2014 Thanks Will, I've ordered some and am interested in seeing the results; although I haven't got a kit on the bench at the mo' so it may be a while. cheers Mike Link to comment Share on other sites More sharing options...
Rick Brown Posted September 18, 2014 Share Posted September 18, 2014 Watching with interest. Mind you, I don't really find Vallejo any better or worse than other acrylics. I'll be interested to see how it works with other brands. Rick. 1 Link to comment Share on other sites More sharing options...
robvulcan Posted September 18, 2014 Share Posted September 18, 2014 I only have one bottle of Vallejo I was told it was very tough flexible and scratch resistant paint. But I am interested in tough paint anyways As I miss the old days of real paint and original Humbrol Enamels which would not scratch off no matter how hard you tried. Even they are not like that now.

cruiserguy Posted September 18, 2014 Author Share Posted September 18, 2014 Hi Rick, It might be me, but I've found Vallejo a bit less durable than say Humbrol, Lifecolor, or Tamiya. Once it's fully cured its OK, but I never found it as hard-wearing as Lifecolor. I won't go back on Vallejo now as I have spent too much time learning how to use them, and too much money on the paint and accessories such as cleaner, thinner, and primers too Best Wishes, Will.

Andrew Posted September 18, 2014 Share Posted September 18, 2014 Thanks for the pointer, Will. I wasn't aware of the existence of this medium and I'm keen to give it a try. cheers, Andrew. Link to comment Share on other sites More sharing options...
viscount806x Posted September 22, 2014 Share Posted September 22, 2014 I've now got a big bottle of this stuff. It looks and smells very much like a PVA derivative. The directions on the bottle are a bit vague but suggest 75% added to the mix for solid surfaces and 50/50 on flexing surfaces, both of which seem a lot. I think I'll just try a smaller amount and see how it goes under the logic that any in the mix at all will strengthen the resultant paint finish. Thinks: Wonder if just sticking a bit of PVA in the mix would achieve similar results. I've done that to concrete mixes before now in order to water and frost proof them and used white wood glue for it successfully. Link to comment Share on other sites More sharing options...
cruiserguy Posted September 22, 2014 Author Share Posted September 22, 2014 Hi Viscount, Interesting that it smells like PVA, it would make sense in a way. The poster on YouTube said mix 1 part of the medium to 3 or 4 parts paint. I'll try it in due course, but would start with a large ratio of paint to medium (>4:1) and work towards the optimum mix. Best Wishes, Will. PS, If it doesn't work sorry for the bum steer. Link to comment Share on other sites More sharing options...
viscount806x Posted September 23, 2014 Share Posted September 23, 2014 Hi Will, I have had another thought: I'm really unsure whether or not it will work with just any acrylic paint. Thinking mainly about those which have an alcohol base such as Tamiya or Mr Color (Gunze). A bit of experimentation is in order methinks. 25% is quite a large quantity to add though and I'm with you on the softly-softly approach. I have a secondary use lined up for this if it doesn't work out for modelling - I have been using acrylic paint and undercoat for decorating in the house for the last year or so because the lack of fumes is quite nice. I think it will work in that to toughen it up a little. Cheers, Nige B Link to comment Share on other sites More sharing options...
