Hey, I was wondering if anyone might have an idea what I was doing wrong with green stuff. I was trying to add a bit to a magnetized metal model with the back foot on the ball of the toes. I tries putting just a little blob of Green stuff towards the center of the foot where it was out of view, but still stabilize it when I change bases. (I magnetized it to switch between a Disc of Tzeentch and a Standard Base.) However, it wouldn't dry to save my life. I used 50/50 green blue and left it for a day. It was still sticky and pliable. I left it another day with a light bulb right next to the feet to give it some extra heat if my coldish room was the problem, but it still did no good.

Any help would be appreciated. A rock to help keep him balanced would look fine on the ground base, but it would look severely out of place on the disc.

How old was the greenstuff? Maybe it's broken down.

Maybe a few months. It's been kept in the tube and was opened up to do that model as I hadn't needed it before; the 2 parts are very pliable and sticky.

I've used a lot of Greenstuff, and not run into this problem. The hardening process is about the two chemicals reacting with each other. It can be slowed by cold or sped up by heat, but the process is the two chemicals. Given a 50/50 mix (or even a 60/40 etc) it should have hardened. Therefore i believe there is something wrong within the Greenstuff. Test another blob separately. I'm going to watch here for other information, would be nice to see a solution or at least a sure causation.

Only thing i can think of was that it wasn't mixed well.

iv had green stuff lying around for years and it works fine.

was it open to the air this whole time? maybe it off gassed some vocs or something.

The only thing I can think of is that you are either living in a jungle and there's too much humidity, or you were eating at McDonalds and then mixed the green stuff with greasy fingers. Other that that I can't think of anything that would cause this. Very strange.

I'll keep you posted.

I assume you're using GWs GS? Theirs is yellow/blue when not mixed, not green/blue. But assuming you mean yellow and not green, did you make sure it was thoroughly kneaded? It needs to become a homogeneous color.

I've got my money on it not being mixed properly. Perhaps maybe the ratios were off as well, but you have to be quite a long way off before it won't cure.

Humidity shouldn't make a difference, I think greenstuff (like many epoxy putties) can cure even if it's submerged under water. Grease I'm not sure, I feel like if you mix it thoroughly it should still cure even if you did so with greasy fingers. As long as the two parts are thoroughly smooshed together they should react which causes them to cure.

Considering that my few sculpts probably had vaseline mixed in and cured just fine, I don't think grease would be an issue. If anything, it'd just make it harder to get to adhere to the model.

My bad, I meant yellow/ blue. It was a brain burp.

I tried another go of it recently. It worked fine with the same mixture. The only thing I can think of is I made sure to pull some blue/yellow that wasn't from the tips to minimize material that had been touched by air for long. It set fine. I'll actually be showing off the kitbashed plaguecaster sculpt a bit later.

Hey, all right! Looking forward to it!
