I just posted this on the Home Decorating forum, then remembered that there is a paint forum!

I just received the brochure for F&B and I'm a bit confused. Here's what I gather:

Eggshell paints are for interior woodwork only?

Modern Emulsion and Estate Emulsion are for walls only? Could you explain the difference between these two options (modern and estate)?

Finally, how is F&B coverage? Does it go well over already painted walls, or will primer need to be used?

Thanks for any and all help!
