painting latex over oil based paint
 
I am painting latex over oil based paint that has also been feather dusted! I used Behr paint and primer after washing and sanding the walls - I have had no issues but I only did one room and now I have the rest of the house to do 2500 sq ft - should I be using oil based primer first?

Unless you are really sanding very well, a good bonding primer is required, not necessarily oil but Zinnser's Cover Stain would be a good one, Bullseye 123 or Fresh Start would work as well

The walls are in oil? How do you know?
And I've never had "feather dusted" in my prep list! lol

Definitely use an adhesion primer. It would be the rare person that would actually sand an oil finish well enough to back over it with just a latex top coat, and if you really read the data for those paint and primer in one products, they sure recommend primer in a lot of situations.

Todays acrylics have a lot better adhesion than those from the past, but a good primer will save you from a lot of future headaches. What looks good today may start quickly peeling off with actual living.
