Okay, so I've recently got back into 40k after a year or two, and I bought some green stuff to help with conversions. I'm currently trying to use it for some vines on a piece of terrain, but it's very brittle and keeps falling apart. It's only the second time I've used it, and it didn't happen the first time. Is there anything I could be doing wrong to make it so weak? Should I be leaving it longer to cure or something?

Thanks in advance.

I've always found that greenstuff is only as strong as the material you put under it. Try starting with a core of thin copper wire. This will ensure you have a strong starting point.

I found that if I left it for about ten minutes, I could make a small amount before it started falling apart. And when it did, there wouldn't be enough time to fashion it around some wire. I'll give it a try though, thanks

if it's curing too quickly try addidng more yellow to the mix, bear in mind though this will make it stickier and IMO harder to work..

Green Stuff, brittle? Eh? Never heard that one mate.

GS is famously rubbery/stretchy and nigh on impervious to breaking. Unless you're somehow confusing milliput for GS, I can only imagine that you've mixed the ratio's way off, or not mixed it thouroughly.

But even still, I don't know how on earth this could be the case. GS just isnt brittle. ???

my thoughts exactly... but still, greenstuff doesn't cure in 10 minutes, what a mystery!

Yeah I'm pretty sure it is GS. I just cut a bit off of the end and mixed equal amounts of the blue and yellow. I'm planning on doing some more later on a few models that need gaps filling, so I'll see if I get the same results then.

Just out of interest, what did the packet say? Stoopid question I know, but you could've picked up some bizzare G/Y plumbers putty for all I know!

I had the same problems with it settng too quickly and being too sticky,but i started putting it in a bowl of water an working with it while completly submerged in water.

I got it off eBay where it was listed as Green Stuff/Kneadatite. It arrived in just a clear bag, with the business' card in it.

Ahh! The penny drops. GW stuff is normally quite good.

You are probably the proud owner of some very out of date, and more than likley incorrectly stored, crap.

Bin it mate and buy fresh.

Yeah I'm kind of a cheap skate, and thought I might as well get some off of eBay first in case I was terrible at it. The fact that I got twice as much for about half the price really cut the deal for me

Once this load runs out, or it starts getting unbearable to use, I'll look into the GW stuff.

The greenstuff is Kneadatite (as you know) and can be found other places. Anywhere that isn't eBay should stock stuff well within the use-by date. GW stuff has the upshot of being easily available, but personally I prefer the tubes which don't have a strip of already semi-cured stuff down the middle. Non-GW brands are also generally cheaper as GW marks it up. A lot of hobby stores should have it, though my personal favourite is Antenociti's Workshop.

I have some plumber putty that is similar to greenstuff in color but has the properties you mention, I don't use it for modelling much. It works great in press mould though as in 10 minutes I have a hard as rock laspistol.

By the sounds of things it already IS unuseable. Honestly, fresh stuff is great stuff to work with, go on, you know you want to.

Just an FYI.

GS may be sold by GW, but it ISN'T a GW product.
It is manufactured by Polymeric Systems Inc and sold through them to other dealers.
(much in the same way as "GW's" basing scatters - they are 'rebadged' products from other manufacturers).

GS shouldn't be brittle as the stuff never truly hardens (if you want a hard edge, you need 'brown stuff'). Sounds like you might have got a bad batch though.

GS gives best results OVER a former for certain shapes. Vines should simply be a matter of rolling out thin sausages and going from there - it DOES need to be kept moist to stop your tool sticking to it and tearing it up though.

I'd recommend the Gale Force 9 tubes.

You get a gak load more for your money, and the two parts come in seperate tubes, so no dodgy part-cured centre line.


Edit - I just chuckled when I saw the auto censoring for the first time. Class! I did think all the fething and gakking was a bit strange when I first saw it.

I wonder...

I woukld say the stuff is out of date, it has to be when its like that to work with.
Best bet is to use that for small jobs (fillinf large areas and work on bases)

Buy some new stuff to work with, you will see the difference straight away.

Ill also second Orki in suggesting GF9 tubes of GS.
Same as GW stuff but alot cheaper and no partial mix.




Orki: Dont go testing that filter too much, it does have limits

I bought a tube off Heresy Miniatures online as I am hoping to do a lot of sculpting.

Had some problems with the GW strip I had previously but it was probably where the two colours touched going off so there were horrid little hard lumps in it.
Possibly it was old stock too.

Just used it up where lack of finesse wasn't a problem.
Like Jack says, for bases and such like.

Yeah, i'm not sure of the exact weight, but you get two sausage sized, umm... sausages of the stuff for a tenner. Easily mebbe 2-3 times relatively cheaper than the GW packs.

Ok I admit it, I couldn't help myself. Tried a few out earlier.

I quite like the GF9 way of putting the two types in seperate tubes. In mine it's all one tube with foil on the ends. Mine, which looks very similar, is 3.5" long for each colour, with 0.75" in diameter. (About 6.18 inches squared, or 40cm^2 for EACH colour) If that helps . Also, testing testing. Is this thing on?

EDIT: Just wanted to add that while GF9 is awesome, it's an American website. There are other places which stock the Kneadatite tubes in the UK, which will save you some shipping. Flames of War is a GF9 retailer and sells the tubes for a tenner.

Thanks for all of the recommendations guys, I'll probably get some of the GF9 stuff.

If you want to save a bit of money and only need a little bit there's a pack here : here
