Change blog post to full width/page layout

When creating a new blog post the standard blog layout is used until you manually switch to the advanced editor and safe it.

I create blog posts by adding the enfold shortcode to the standard text field. But if you do that, the code is shown in the standard blog design.
If I open the page, switch to advanced editor and then safe it, everything is fine.

If I do the same with a page, it works fine. But I can’t use that, because I need to show these pages as a blog.

The problem is the standard layout of the post, with the meta data, thumbnail from the post etc. After changing to advanced editor and saving it, it’s fine.

Because all posts are created automatically I can’t do this manually.

The question is: how can I change the design of a standard post to the same design of a new page?
