Green Stuff curing issues?

[ScottRadom]

Hey, can anyone tell me if Green Stuff needs air to cure? If I coat a base in PVA glue and sand immediately after I put the green stuff on will the green stuff cure at all, be delayed, or no effect?

Thanks to anyone who can answer.

I\'m pretty sure it\'ll cure fine. I\'ve been impatient and primed miniatures immediately after greenstuffing parts of them. I don\'t recommend it because greenstuff changes volume slightly as it cures, which can cause cracking and stuff on its surface. The parts hardened just fine at any rate.

It\'s a tiny little % of volume change, but it\'s noticeable.

Coolio. Thanks for the answer. I can deal with a small percentage of loss as it\'s just to provide some hieght and bulk to the base, which will get covered in sand, static grass ans silfor tufts anywoo.

Much appreciated, I\'m off to base up my first Avatars of War fig and I\'m exicted.

Greenstuff curing is independent of air, it\'s a chemical reaction rather than air drying. It\'ll even cure under water or while wet. (I used some to fix a leaky faucet in a pinch as I\'d heard it was similar to plumber\'s putty once.)

I can\'t really understand what you\'re looking to do here. You could just build height with Polyfilla, or PVA + fine sand, or a mixture of the two. Besides, how can you sand wet GS without it clogging up the paper?

Shrinkage is less than 1% according to the literature. If you were sculpting something 32mm tall in a single go that\'s going to be 0.3mm, max, over the total height; I think you\'d have to have pretty good eyes to be able to notice that!

Einon:

Yeah turns out the language i used was less then 100%. I wanted to put green stuff on a models base and COAT with sand immediately so I could start work on it the next morning. Oops. Anyway I tried it last night and after about 10 hrs it looks fine, and shinkage was not an issue.

I just wanted to increase the height of An Avatars of War model so it would rank up better when Iplay warhammer. I got a few hours of this morning at the last minute and wanted to try that project as a break from the regular stuff I\'ve been working on. If I could plan better I wouldn\'t have had to rush but such is life!

Wren: Thanks for the tip! I wasn\'t sure if GS cured through and aerobic action or not.

Aha! Well that sounds fine - I\'ve embedded things in curing GS, MagicSculp and another epoxy putty without problems.

Works well for me too, I have done it a few times especially on bases.

I have used this several times in building up bases, actually I think it is almost a must if you play warhammer fantasy.
