I use this product on most of the items I build for my Tau base on a desert world terrain set up. Have a look at my galleries for examples of it in use.

On most of my buildings I leave it the "straight out of the can" colour, but sometimes I paint over it. The texture works well on buildings but it would be too rough for small figures, I think. (There are several different colour mixtures, if you want to use it for scenery items.)
If you want to do a textured finish on 28mm figures, you might find something useful in acrylic media.
