Adding texture / dragging a dry brush

[Hansi]

Hi Guys

I'm trying to find out if it's possible to create texture by dragging a dry and loaded brush across a textured underpainting, allowing the underpainting to show through, as you would if using acrylics or oils? I have tried using 'insta-dry' but it seems too clean and regular, whereas I'm trying to get a rough look...like in this attachment for example....



I would really appreciate any advice or help...

Cheers, Hansi
