Do this before you put anything into the directory. The directory permissions take precedence so you can then put files or other folders into that container and they will be protected from unwanted viewers by the directory permissions. It is common for folks to create a "personal" or "private" folder which is restricted to themselves. You can use this as a personal cloud to store anything from anywhere on the web or any computer and it is protected from others. You might also create folders for "family" and "friends" with permission granted to appropriate privacy groups.
