Some weathering powders advertise that they contain an adhesive. Has anyone tried these & do they really stick to the surface? Also I have a lot of powdered chalk & was wondering if I could add some kind of adhesive to them. Can’t think of anything that wouldn’t harden up before you had a chance to use them up…any suggestions? thanks. Jerry
I can’t think of any kind of adhesive that could be added to powdered chalk without turning it into a brick. I use AIM weathering powders in my modeling. They do stick to the surface and anything else that they come in contact with, including you and your clothing. Fortunately it does wash out.
Bragdon Weathering Powder are the ones billed as the ones with adhesives properties. You’ll still need something like a coat of dulcoat to give it something to bite on. You can find them at many train/hobby stores. AIM and Bragdon powders are probably the two most popular brands. Some like one better than the other but that is individual preference.
Here is a youtube video of a guy from NY using weathering powders and dulcoat. A warning though, the background music is boom music with language that may be offensive. Don’t worry if you mute before because he does no talking in the video. It just shows him working at 2X speed. I think he is using AIM.

A few folks, including me, are now using Krylon Crystal Clear mat finish from Walmart for about $3 for an 11 oz can as opposed to $5 for a 3 oz can of Testors dulcoat (got this from one the youtube videos). By using either dulcoat or similar you give the powders something to bite on. When you affix or seal the powder with dulcoat you will wind up “washing” powder off as well as the color. This is even more true with lighter colored powders. The darker car color will also “wash” the color of the powders.

Bragdon and Bar Mills powders and probably others say the powdered adhesive built in is activated by the rubbing of the powders on the surface. I think they are great, and gave up on chalk powders when I discovered them.
