Talcum Powder for weathering

[Olie]

I have read a couple of article, albeit older one, that talk about using talcum powder for weathering. I mixed up a 50/50 mix of baby powder with the black chalk line powder I had to make a grey. Seems like it would do the trick. I'm wondering how well it will stick and if it has issues if a clear is sprayed over it. Anyone else use something like this?

I have not heard of this, but weathering is not something I've researched all that much. If you remember articles on the subject than it must work somewhat. Take a few different scraps of material, and experiment to see if it works on a;; materials, or just some. Be sure to post results. It might work really well for concrete look.

We have a brand of baby powder here called Curash, contains Zinc Oxide and Cornstarch. It clings very well, probably because of the Cornstarch. I imagine various color chalks could be combined.

I use Bragdons Weathering Powders, which are excellent I might add and stick like poo to a blanket, but tried using regular chalk rubbed against sand paper prior to the Bragdons. What I discovered was it didn't stick to anything terribly well and when a clear coat was applied, that tended to "blow the chalk" around. Because it didn't stick, it didn't matter what color I used, the color didn't stay/show up.

The other (almost opposite) issue I discovered was when using chalk to replicate mortar lines between the bricks. One of two things would occur when giving it a clear coat - the clear coat would blow the chalk around and cause it to clag up heavily in spots across the wall.

Now, using chalk powder with baby powder might be better, I really can't say but can;'t imagine it improving the adhesive qualities of the chalk either.

Would be terrible if Bragdons and others were only colored Cornstarch, eh.

Yep it would and thankfully Bragdons isn't

I've heard a lot of good things about Bragdons. I will get some of their stuff, in the meantime though, I'm always looking for new a different ways to use on hand items.

There's a lot of different mediums that could be use for weathering like cornstarch, makeup, etc. While they may work when initially applied, the long term durability of these products is unknown.

I would stay with the main stream weathering powders, oils, paints and caulks.

Thanks.

I have no experience with Bragdon, but AIM and Humbrol powders both work very well for me. I have heard/read that Doc O'Briens powders are also good.
