Genesis Dambuster has to be “switched on” for each page where you want it to apply, individually. You do this in the Dambuster settings panel that appears underneath each page and post.
There is no setting to switch it on for every page and/or every post at once.
If you find that you want this functionality, then Dambuster is not the right solution. In this case what you need is a different theme, or for someone to make structural changes in the code to your current theme in order to arrive at the theme you want.
Genesis Dambuster is for tweaking the odd page or post, not for restructuring whole themes.
