Hey Dakka, I recently picked up some liquid green stuff at my local GW as an impulse purchase whilst stocking up on some paint. I've never used any form of green stuff before and I was just wondering what on earth do I use this stuff for?

you brush it on, for filling very minor gaps, or scratches or abrasions in a model before priming or painting.

It shrinks quite a bit, but is fairly easy to use.

I do like it for certain applications (smoothing something out, very small gaps) but use better fillers (there are tons) for bigger gaps.

Very cool, thanks for the tip. Is there a different form of green stuff that modellers use for creating custom bits? I could've sworn I used to read about it in various White Dwarfs back in the day...

It's there to fill the holes in finecast.
They'd never actually outright state that but it was designed exactly for that purpose and that's what it's used for 99% of the time.
Having said that it's pretty good for just cleaning up non-plastic models in general.

Grenn Stuff putty is a two part epoxy resin -- blue and yellow that mixes to green -- used for filling gaps and making parts. It is widely used by sculptors to make master figures.

There are various types of epoxy putty on the market. GW's Green Stuff is made by Kneadatite and can be found under that name much cheaper than in GW shops.

Milliput is another useful two-part putty that cures to a much harder finish. It can be sanded and sawn.

There are also one part putties like Squadron Green or White. These are good for filling gaps because there is no mixing and you just blob out the amount you want to use.

Other companies offer alternatives to GW's Liquid Green Stuff, for example Gunze-Sangyo's Mr Surfacer.

I find LGS is good for putting over the join point on plastic models too, it blends one half into the other so I have a nice smooth finish for priming.
It makes for a better looking paint job.
I also use it for blending in other sculpting I've done.
It's by no means essential, but I find it quite useful.

So leme get this straight;
liquid greenstuff;
shrinks,
is not sandable,
and is not 'greenstuff';clealy isnt 2 part epoxy as it would set in the pot long before we seen it.

The shrinking and lack of sandability make it the worst possible gap filler going. And thats what is supposed to be used for? lol wtf... seems like a non product to me.

Liquid Green Stuff is GW's version of Mr Surfacer or the Vallejo acrylic plastic filler.

Aero modellers use them a lot for filling small gaps.

The shrinking can be a benefit in creating smooth surfaces (i.e. it thins down flat) and it is a damn sight less shrinky (?) than glues that some would use.

LGS is a decent product, I'll not comment on the price but it is really useful for a range of small jobs. It is primarily for joints and in essence fulfils the same role that jointing plaster does; drops in the gap and also forms a neat layer over the two surfaces. Done right (with a wet brush) it can be a quick and tidy solution and doesn't require sanding.

For example I was recently struggling with a gap between the edges of a paper finish I had applied to some bases and the bases themselves. I have a plethora of fillers and putties (don't we all ) but none of them could easily be used in the gap without tearing the paper. A small brush full of LGS did the trick and I had 15 bases dome like that in not time.

Its a good product and like most fillers its situation based upon its properties.

It's like a thin Squadron green without the toxicity!

about all people use it for is filling mold "bubbles' on finecast. I also use it when im using Cork plates along the edges to strengthen it, so i dont get bits of my "rocks" chipping off and showing cork lol.

It's for filling in holes on the model.

Its for filling small gaps, if you are giving companies money for models with holes in them I would suggest you have bigger problems than 'what filler?'

I'd also consider it a pretty essential product, I like it a lot.

Yeah, as others have said, its not really comparable to "green stuff" or other two-part expoxy putties, which all fill different rules.

It is much closer to other surfacing products, like the vallejo liquid plastic, some of the mr. surface products etc.

I have found it a useful tool in my "filler" collection...each to their own job.

Use it a while, you will see where it works well...and where it does not. Chances are, where it does not...its not designed for that role - another product is with different characteristics.

best of luck!

I've seen one person use it paint on runes for his space wolves. Layering it up with multiple coats.

I use my own version of liquid green stuff ( plastic cement with some sprue shavings dissolved in it ) for small gaps and mould lines ..i alos use Apoxie sculpt(a nice two part light grey sandable epoxie for some sculpting (dries hard) and green stuff (plumbers blue/yellow) for others (dries to a semi flexable state)..depending on what I am doing ..the Blue /yellow is far easier to make small detail parts with than the Apoxie sculpt ..the ApoxieScuplt is half the price and is sandable (great for vehicle extentions and some terrain)

Although people initially hated LGS because it was introduced as a way to fix the issues with Finecast minis from the consumer end instead of the production end, I think that it's one of the best products that GW has introduced into the hobby in a long time.

As others have mentioned, there are other products that are similar but this one is water based, very forgiving, and sandable. It's perfect for fixing small problems that are overkill for epoxy putties. I use it all of the time. If you thin it down it even makes a decent brush primer in a pinch.

Bear in mind GW didn't introduce it into the hobby. They introduced it into The HHHobby.

Liquid putty products were around for years before GW repackaged them for fixing Finecast.

What did I say?
