This is absolutely stupid question but how I can flip surface? I was thinking that direction of normal is direction surface but flipping normals doesn't do anything. When I polyextrude the surfaces (see attachment) some surfaces extrude in different direction.
or just make sure you have normals oriented in same direction and when you extrude use “existing normals”, don't let the polyextrude to precompute them.

The Reverse was exactly what I was looking for! Thx
