Wanted: a blogless theme

I have looked, and previews, and installed, and activated theme after theme, but I cannot find one that doesn’t make pages that don’t say should be blog pages, look like a blog page. I have found a theme or two that gets me closer to other things I want for my site, but I am trying to build a web site, not a blog. I would like to have one page that is a blog, but most many pages, including the main page, must have nothing that looks like a blog page. Even when I searched for small business themes, I still got pages with a place to write and a way for people to comment on that post. Real web sites, as opposed to blogs, do not do that. Is there no way to find a theme that requires extra effort to look like a blog page but by default, makes every single page look like a web page at a normal business web site? Or, do I really have to go into the code behind every single page and rip out the blog junk? Surely there are some themes that are for web pages, not blog pages, but all my searches have not found one. Any suggestions? Thanks.
