So, I made some flocking using very fine sawdust & green acrylic paint. Forced as much as I could through a sieve but was left with many clumps and larger pieces. Image Here: imgur.com/gallery/ybPjqOXThey will crumble under medium pressure but it is slow, tedious work. Does anyone know what I may have done wrong? & Any method that would make crushing them easier?

I have only made it once, but, you may not have stirred it enough while mixing the paint. I stirred mine continuously while adding small amounts of paint at a time. I think the larger clumps can be ground down in a small coffee grinder. Battery powered ones are fairly low cost.

The different colors in the flock give it away I think. Also did you thin the paint a bit? if so I would thin it a little more.

The differing colors is the result of three separate batches mixed together after they were dry. I'll thin down the paint & try a new batch in the next couple days. & I'll be sure to add it incrementally, thanks Sam. Let y'all know how it goes. As for the lumpy bits, I may try to blend them up, although I'm also brainstorming some other ideas for them.

ok, sorry then good luck, let us know if it worked!

Aside from the clump sizes, I don't see an issue. It looks quite good. The clumps may not be a bad thing: how about gluing them on tree branches, to represent leaf clusters? Otherwise, I second the battery coffee grinder idea. Should fix them right up. Cheers!

if you want instant stuff like scotty does then you have to water down the paint a bit. making it easier to "dye" the stuff. aside from that paint will make them stick together if you let it dry. so making flocking for later use is soemthing that will happen often. i made flocking like 3 times still have a full bottle of green flocking.
what i did...
- put saw dust in the bowl. - add paint unwatered (in hindsight i should have) - mix it up and just really really mix it up. - let it dry - use sieving to make kinds of flocking. - one bottle of fine flocking which i just sieved thru small sieve. - one big where i just left it as is.
thats it, got the job done really. i just think there is no right or wrong way to do this. sometimes you do want big clumps, other time you just want it fine.

I had that issue all i had to do was add some small rough rocks to the bucket and shake the crap out of it

Nice! Old school grinding technique. Cheers!

if that help: here we use watered ink instead of paint and it doesn't have sticking issue the method is (thank to a mini train collector buddy): take a bowl of watered down ink trow the sawdust in it stir a lil take of the sawdust with a sieve spoon put the sawdust in an old rag and press the wole thing to get rid of the water put the sandust in the oven (spread it on cooking paper) at 80°c to dry it of completly now you have a nice flock
it may seems complicated but the whole thing take 15min

I have a question about the clumps. Can they be allowed to dry out completely and then forced through the sieve again?

Forcing the clumps through the sieve again, would basically be a grinding technique. It could work. Experimentation is king, Baby!

Thats what i did for mine yes. i made the thing in bulk, let it dry and then just passed it through the sieve.

How did your second batch turn out? My latest big, clumpy batch, unfortunately, gave me more troubles than the first. I have difficulties getting much through a sieve and am inundated with a majority of the sawdust in bits too large to appear natural. Alternatively, the batch that started the thread ended up beautifully. I was able to commandeer an old ' magic bullet' and grind it all down, the end result was perfect. Now, trying it out with this batch, either the sawdust is somehow different or (more likely) I've dulled the bullets blades. I have heard of people using a coffee grinder for this purpose and might try that if I can find a decent one for cheap. Thanks for asking.

I have heard of people using a coffee grinder for this purpose and might try that if I can find a decent one for cheap. Thanks for asking. I've been experimenting a bit with doing flocking my self ( using wood flour meant for smoking fish as it's commercially available and sterile ) I've not had any problems with clumping so my procedure may help you out: 1) Take a container and fill a little bit of distilled/demineraliserede water ( or use tap water I guess ), I used maybe I used just shy of a shot in a disposable plastic cup 2) Add a couple of drops of dish soap and stir gently 3) add bit of cheap acrylic paint. gently stir until the paint is completely dissolved, the amount only affects the intensity of the final colour but make sure not to add so much it cant dissolve complete - if it doesn't go back to step 1 and start over 4) add some wood flour and stir until it's completely coloured in 5) repeat step 4 until the the wood flour has the consistency of damp sand 6) spread it out on some baking paper in a thin layer 7) optionally put a 2nd baking paper on top and go ham with a rolling pint to make the wood flour layer very thin ( to speed up drying time ) once dry fold the baking paper up and pour the contents into a container for storage Only one batch had some slight clumps in it but those broke apart easily when I rubbed it between my fingers so I just poured it into a storage container and shaked it vigorously which got rid of them. The reason that one batch had clumps was that I didn't stir deep enough so the wood flour at the bottom of the cup was still still kind of globby I've a few more questions but I think I'll make a separate thread rather than continue hijacking this one ps. apologies for any spelling errors but I cannot find my glasses atm. so I have to rely entirely on the browsers spellcheck xD
