If you paint brick, you've turned a maintenance-free surface into one that requires maintenance. I understand that you want to be able to 'clean' the brick surface after a while.
As for the Behr, if you've been reading what 'we' say about the paint being sold at Home Centers, I say return it. Look in the Yellow Pages under PAINT - RETAIL for a Paint Retailer near you. They have expert advice! Yes, you'll pay more but it's worth it. The paints in the Retail Stores ARE of a better quality. (Ask any Professional Painter.) My personal favorite is Finneran & Haley. It's local to my area but others swear by Sherwin-Williams, et al..
My best to ya and hope this helps.
PS: Do a good job of the preparation work. And get your primer from the Retail Paint Store too. If you're painting in the kitchen, consider oil-based paint although you can ask them what 'they' think (at the store.)
